dusky, incompletely outlined by blackish scales. Secondaries smoky, paler at base, the fringes whitish. Beneath, whitish, the primaries smoky on disk; both wings with discal marks and more or less obvious extra-median lines.

Habitat: Esper Ranch, Brownsville, Tex.

One male and one female, in good condition; from the collection of the Brooklyn Institute of Arts and Sciences. The species is allied to vinnula and paupercula, but is smaller than either and much more delicately marked. Comparatively, also, the primaries of the new species are shorter and broader.

Noctua larga nov. sp.

Head and collar bright rusty brown, the head darker in shade. Thorax brown with a more or less marked rusty tinge. Primaries gray-brown with a reddish tinge, varying in the specimens. All the lines single, punctiform. Basal line marked only on costa and in the cell. T.a. line with black venular spots and a scattering of black scales that marks the line across the costal region. T.p. line even, marked by distinct black dots on the veins, in course parallel to the outer margin. S.t. line wanting. A series of black, inter-spatial terminal dots. Claviform vaguely indicated by scattered black scales. Orbicular indicated by a few black scales, or altogether wanting. Reniform marked by a black dot and a variable number of black scales; not complete, or even so outlined as to make out a definite form, in any case. Secondaries pale at base, outwardly dusky, darker throughout in the female. Beneath, primaries smoky, secondaries whitish, both darker in the female. Expands 1.80-2.10 in. = 45-52 mm.

Habitat: Palmerly, Cochise County, Arizona, August; Huachuca Mountains, Arizona, June 16.

Three males and one female, in good condition; from the Museum of the Brooklyn Institute. The specimens were taken by Mr. Carl Schaffer, who says they were commonly found under shelter, much as our clandestina are sometimes found in large numbers. There are other rubbed examples in the Museum collection; but all seem to be very much alike. The large size and simple markings, allied to those of clandestina, distinguish the species.

Rhizagrotis acclivis Morr., Ann. Lyc. Nat. Hist., N.Y., XI, 93, Agrotis, 1875; reclivis Dyar, Jour. N.Y. Ent. Soc., XV, 106, Rhizagrotis, 1907.

Mr. Morrison's specimen came from New York and the type is in the Tepper Collection. About the same time, Dr. Harvey described Agrotis opaca, from Texas, and in 1890 I recorded my belief that the two gentlemen had named the same species. I had, then and later, examples from Texas,

Arizona and Colorado, and, as the type of maculation and structure was unusual for the eastern fauna, I questioned whether the locality of the specimen in the Tepper Collection might not be erroneous. An examination of Dr. Harvey's type in the British Museum confirmed my belief; and in my Catalogue of 1903 (Bull. 44, U.S. Nat. Mus., 79) I cited the two names as referring to the same species, and gave the New York locality with an “(?).” Until 1907 I did not see another eastern example, though I had a number from southwestern localities. In a miscellaneous lot received from Dr. Dyar for determination, there was an example which I named acclivis, and to which I appended the note quoted by Dr. Dyar: "The first authentic specimen I have seen from this region. It indicates that the New York locality which I questioned in my Catalogue may have been correct, or it may indicate two very similar species which I have not had material enough to discriminate."

Dr. Dyar did have material to discriminate, and he gives the differences between the eastern and the southwestern forms; but in giving a name he re-describes the eastern form that served Morrison as a type, and therefore creates a synonym merely. I assume that Dr. Dyar is correct in determining that there are two species, though I have not been able to verify that point; but, if this is so, it simply means that Dr. Harvey's name must be restored to the list and that the southwestern specimens now labeled acclivis Morr. in collections must be re-labeled opaca Harvey.

Euxoa cocklei nov. sp.

Head, thorax and primaries dull brown, varying from chocolate to smoky, and more or less irrorated with black. Collar with a more or less marked black median line. Disk of thorax and patagia with a sparse admixture of yellow scales. Primaries with all the maculation traceable, and usually well written. Basal line geminate, black, included space yellowish. T.a. line geminate, included space yellow, the edgings black; upright to median vein outcurved in the space below and outwardly bent below vein 1. T.p. line geminate, inner portion lunulate, not well marked, outer portion hardly distinct; the included space yellowish, variably marked and not always continuous; in course moderately outcurved over the cell and then parallel with outer margin. S.t. line a little irregular, broken, yellowish, sometimes reduced to scattered yellow scales. A series of dusky terminal lunules, which are rarely distinct. There is a tendency to a darkening below the median vein, between the basal and t.a. line, and in one example there is a distinct black line. Claviform moderate, black-bordered. Orbicular round or oval, moderate in size, with a narrow black edging within which is a ring of whitish scales. Reniform moderate in size, kidney-shaped, edged with black scales, then with an inner (more or less incomplete) border of yellowish; the spot sometimes darker inferiorly. Secondaries smoky yellowish, almost uniform, with an obscure dusky lunule. Beneath, dull

smoky; secondaries more yellowish and powdery; all wings with an outer shade band and discal mark, less evident on primaries.

Two males and five females; from Dr. James Fletcher, collected by Mr. J. W. Cockle, after whom the species is named. All the examples are in good condition and no two are alike. The two males are smaller than all the females, although the larger of the two is almost as large as the smallest female. So the males are also darker and less distinctly marked, the ornamentation in one case, indeed, being scarcely traceable. In all the females all the markings are at least traceable, and in one case every feature is complete, and, in addition, the s.t. space is a little paler than the rest of the wing. The type of maculation is similar to insulsa, but there is no darkening of the cell and the wings are also too powdery. There are no strong positive characters, and in Hampson's Tables it falls between submolesta and procellaris, neither of them American species.

Euxoa criddlei nov. sp.

Head, thorax and primaries mahogany-brown; the head and thorax darker, without markings; primaries with all the transverse maculation lost, except the s.t. line, which is traceable by a line of pale scales edging the darker, more blackish terminal space. No trace of claviform. Orbicular faintly indicated by a blackish powdering. Reniform faintly outlined by scattered pale scales inferiorly filled with blackish. Secondaries dull yellowish becoming smoky at outer margin, with a dark discal lunule. Beneath, smoky, powdery; primaries darker; all wings with a discal lunule. Abdomen dull smoky.

Habitat: Aweme, Manitoba, Aug. 24, 25, Sept. 4.

One male and two females, in good condition; from Dr. James Fletcher, collected by Mr. Criddle, after whom the species is named. This is a very simply marked form, and in fact, at first sight there appear to be no markings at all, so feebly are they indicated. In wing form the species is like pastoralis, with which it will be most naturally associated in the list. In Hampson's Tables the species would fall in next to stigmatilis Sm., to which the new species has but a slight resemblance.

Euxoa quinta nov. sp.

Head, thorax and primaries dull ashen gray, the entire surface with uniformly placed brown irrorations, which are quite conspicuous under the glass, and give a soft shading to the insect. Transverse maculation, except s.t. line, brown or black

ish, broken, more or less lost. S.t. line pale, rather conspicuously relieved by a smoky preceding shade. Basal line marked by a geminate spot on costa and sometimes by a dot on median vein. T.a. line geminate, outer line best marked, evenly oblique, with small outcurves in the interspaces; always broken. T.p. line geminate, only a little bent over the reniform, parallel to outer margin; outer line a series of venular points; inner tending to become diffuse. A broad, diffuse, obscure median smoky shade. S.t. line irregular, complete or nearly so, emphasized by white scales. A series of small black terminal dots and a narrow line at base of fringes. Orbicular moderate, round or oval, incompletely marked by whitish scales. Reniform moderate, kidney-shaped, outlined by a vague yellowish ring, inferiorly black-filled. Secondaries smoky fuscous, more yellowish at base, with a dark discal lunule and pale fringes. Abdomen pale ashen gray. Beneath, primaries smoky with a powdery pale-gray border, an extra-median line marked on costa, and an obscure discal spot; secondaries pale gray, powdery, with a conspicuous black discal line and an incomplete extra-median band, beyond which the marginal area is blackish.

Habitat: High River, Alberta (Mr. Thomas Baird); Kaslo, B.C., June 1, 30, July 7, 10 (Mr. J. W. Cockle).

Three males and two females, all in good condition; received from Dr. James Fletcher. The examples are all very much alike, a slight difference in the amount of dark filling in the reniform and in the completeness of the transverse lines being all the variation noted. The species belongs with the bostoniensis series, but differs from all those previously known to me, in the dark secondaries of both sexes. It recalls scandens at first sight, but is much darker than that species throughout.

Euxoa capota nov. sp.

Head dark brown in front, vertex reddish gray, a black line dividing the two. Collar reddish at base, tip velvety black; a white line between the two. Disk of thorax reddish gray. Primaries brown; median space very dark purplish brown, almost black; costal region to t.p. line whitish; the ordinary spots of the brown ground-color. A black basal shade margins the costal pale area inferiorly. T.a. line geminate, black, obsolete on costa, very distinct below it and with an inward curve at the middle of its course. T.p. line geminate, black, the outer line less distinct, almost straight from the costa to end of cell and then with a very small incurve. S.t. line pale, only a little irregular, chiefly defined by the slightly darker terminal area against the s.t. space, which is the lightest part of the wing. Claviform narrowly outlined in black, incomplete, concolorous. Space between the ordinary spots black-filled. Orbicular, U-shaped, open to the costal pale area. Reniform large, incompletely outlined by dark and pale scales, lunate rather than kidney-shaped. Secondaries smoky brown, with a small, darker discal lunule. Beneath, reddish gray, powdery, with a common outer line and a discal lunule on all wings.

Habitat: Palmerly, Cochise County, Arizona, July and August.

Eight examples, mostly in good condition, all very much alike and all females. The reference to Euxoa is in the sense in which that genus is used by Hampson. The frontal structure in this species is as in Chorizagrotis, but the body is not depressed. As there are no males, the antennal structure of that sex cannot be used as a guide, and the generic reference must be provisional. The species is altogether unlike any other form known to me from our fauna, and the peculiar course of the median lines should serve as a means of recognition.

Ufeus electra nov. sp.

Ground-color dull chocolate-brown. Head and thorax with dark hair intermingled. Primaries so densely set with long black hair as to give the whole a blackish appearance. A black basal streak in the sub-median interspace extends almost to the middle of the wing. Another streak extends, with little interruption, through the cell and beyond it to the outer margin. T.a. line lost. T.p. line outwardly bent from costa, obscure, blackish, with small outward extensions on the veins. A series of black inter-spatial marks at base of fringes, becoming longer toward the apex. Secondaries dull yellowish, smoky, with an overlay of black hair; a distinct discal lunule and a well-marked extra-median shade line. Beneath, reddish gray, powdery, darker at the margins on primaries; secondaries with an obvious extra-median line and a distinct discal lunule.

Two female examples, without date or name of sender. Evidently they are electric-light captures, and more or less defective; but their difference from the allied forms is obvious. The species is nearest to plicatus in type of maculation, and it is quite probable that in some specimens, traces of the discal spots will occur.

Ufeus hulstii nov. sp.

Ground-color rather light red-brown. Head and thorax without markings. Primaries with fine black hair, the veins a little darker. T.a. line distinct, single, blackish, outwardly oblique, with three distinct outward angulations, one on the sub-costa, one below the median and the other on vein 1. T.p. line single, black, followed by a slightly paler shade, evenly and moderately outcurved, with short outward spurs on the veins. A series of small black terminal dots. Fringes cut with yellowish. Secondaries silky gray with a reddish tinge. Beneath, very pale pinkish gray, immaculate.

Expands 1.38-1.42 in.

= 34-35 mm.

Habitat: Black Hills, Wyo.; Stockton, Utah, July 22.

Two male examples. One of them is from the Hulst Collection, with
