catalogues, without any published characters, I abandon it and adopt Escholtz' manuscript name of Adoretus, as the characters are detailed by M. Laporte in the 'Suite de Buffon (Articulés), vol. ii. p. 142.

Sp. 41. femoralis. An Adoretus of Escholtz, and the type of the genus, (according to a manuscript letter which I received from the author previous to his death), is Melolontha compressa of Weber. The species allied to it are chiefly from tropical Africa, Asia, and the Polynesian Isles. It has been reported in England and France that Dr. Escholtz died of cholera; this is erroneous, as he died of a bilious fever.

Sp. 42. cærulea. I consider this insect as a Popillia; it occurs in the East Indies, and not in Africa.

I

Sp. 43. cæruleocephala. Now a Popillia. In form it approaches the African more than the Asiatic species, its locality is probably the Cape of Good Hope. The reader is referred to Mr. Newman's monograph on this genus. Sp. 44. bipunctata. The type of the genus Popillia, Leach. No locality is mentioned by Olivier; it is from the Cape. Sp. 45. maura. This insect is the same as Melolontha cardui, Fab., and is the type of Latreille's genus Glaphyrus. Sp. 49. globator. This insect appears to afford sufficient characters for constituting a sub-genus: it is probably a Schizonycha of Dejean; as, however, the Baron has not published its generic details, I cannot adopt it. The form is not confined to Africa or Asia, it occurs alike in the old and new world.

Sp. 51. rauca. An Apogonia of Kirby. M. Laporte mentions two species from Africa, namely, Ap. africana and pusilla, from Senegal.

Sp. 54. rufa. I have not seen this insect in any collection but the Banksian: from the description and general appearance it cannot be ranged with any modern genus. Sp. 58. errans. No locality is mentioned by Olivier: I have received it from M. Leconte, of the United States. Sp. 59. innuba. This insect I have received from Rio Janeiro its country is not mentioned in Olivier.

Sp. 60. nitidula. Entomologists must be careful not to confound Mel. nitidula, Fabr., (which is probably an Anisoplia), with Mel. nitidula of Olivier. The latter insect is probably a Bolax of Fischer.

Sp. 64. aulica. Olivier has properly changed the annexed

The Monograph is unpublished; a synopsis of the new species is given in the 'Mag. Nat. Hist.' vol. ii. n. s. p. 336.-Ed.

name in his work to aulica, which Fabricius in his 'Systema Eleut.' had converted into aulicola.

Sp. 67. gibba. Now a Trochala of Laporte. Vide three new species of this genus described in the 'Suite de Buffon, Hist. Nat. (Articulés), par Laporte de Castelneau, p. 149, vol. ii.

Sp. 68. versicolor. In my 'Manual' I have given this species as a Serica, ML.; it may however belong to the genus Trochalas, Laporte.

Sp. 69. variabilis. The localities of North America and Germany are given to this insect: probably more than one species is included under the name.

Sp. 73. Zebra. This insect is the type of Strepsipher, G. P. No locality is mentioned by Fabricius; Olivier mentions South America as its country, which is erroneous: I have frequently received it from the Cape of Good Hope. Cetonia vittata, Fabr., is the Mel. Zebra of Olivier.

Sp. 74. vittata. Now a Glaphyrus of Latreille. I have lately received it from Persia.

Sp. 75 & 76. These insects are the different sexes of the same species; the former is the male and the latter the female of Amphicoma vulpes, Fabr.

Sp. 77. crinita. According to Olivier Fabricius cites (Pallas 'Ins. Siber.' tab. a, fig. 17), Scarabæus bombyliformis, as Mel. crinita; the former author thinks that the insect described by Pallas is distinct.

Sp. 81. proboscidea. Olivier states that this species occurs in Asia and Africa; I am disposed to think it peculiar to the East Indies.

Sp. 82. limbata. No locality is mentioned in Olivier, it is undoubtedly from the Cape, and the type of the genus Agenius of Serville.

Sp. 83. praticola. Olivier's figure would lead one to believe that praticola was an Anisoplia, according to Illiger it is an Hoplia.

Sp. 88. regia. This species was named regia by Fabricius; the Linnæan name aulica should be adopted, as previously used by that author. It occurs in Spain and Barbary, from whence I have received it. Sp. 96. marginata. I am totally unacquainted with this insect. I give it as an Hoplia; without a doubt its locality, according to Badier, is Guadaloupe.

Sp. 98. atomaria. M. le Baron DeJean in his catalogue, gives the generic name of Gymnoloma to this insect. As I am not aware of the characters being published I purposely refrain from adopting it. Any future entomologist who chooses to publish the details, is entitled to name it. Ma

nuscript names published in catalogues such as Dahl's, Megerle's, and DeJean's, &c. &c. &c., cannot stand.

Sp. 99. crassipes. In my Manual I considered this insect as a Monochelus of Illiger. It appears to be a Pachynema of Serville, according to M. Laporte.

Sp. 101. Podagricus. I am inclined to consider this insect as a Cape species, although the locality given by Olivier and Fabricius is that of Coromandel.

Sp. 103. gonagra. In the same Manual I gave the term Monochelus to the above species, with a query, and as I suspected, it turns out to be a Dichelus of Serville.

Sp. 106. longipes. Probably a Dichelus; the locality is the Cape of Good Hope.

Sp. 108. monticola. All the species of this genus are peculiar to the Continent of Australia.

Sp. 110. rarians. I know not under what modern genus I can place this species; it has never fallen under my inspection. Can it be a gigantic Anomala?

Sp. 112. hæmorrhoidalis. No locality is given by Olivier. From the figure I am inclined to consider it a Mimela, and consequently as inhabiting the East Indies.

Sp. 114. picipes. I have added the name of Mimela with a doubt; the country is not mentioned.

Sp. 116. ignea. Probably a Bolax of Dr. Fischer.

Sp. 121. 12-punctata. This species is evidently the same as Sc, aureolus of Pallas, and is now considered to be an Hoplia.

ART. IV. Description of two new species of Beetles, belonging to the Family Cetoniidae of MacLeay. By Mr. ADAM WHITE. THE two species now to be described belong to a family which comprises about 600 species, and is peculiarly tropical, not more than seven species having been registered as British by the most latitudinarian entomologist. By Linnæus and old authors they were included in the genus Scarabæus, and even after the division of that overloaded group into several genera, some of the Cetoniide were placed along with Melolontha. Latreille, MacLeay, Kirby, St. Fargeau, Serville, Gory and Percheron, have by their labours, rendered the study of them a work of comparative ease.

The genus Trichius of Fabricius, distinguished at once from Cetonia of the same author by many characters, among others by the mentum not covering the maxilla, and by the epimeron (Audouin,) (pièce axillaire Latr.) not being promi

I

nent between the thorax and elytra, contains several remarkable forms; one of the most singular of these is a very flat African genus first characterized by Mr. MacLeay in the appendix to his celebrated' Hora Entomologicæ,' part I. p. 151, and there named Platygenia. The only species known at the time of the establishment of the genus (Pl. zairica,) seems to be the insect described shortly before at great length by Afzelius, in the appendix to the third part of Schönherr's 'Synonymia Insectorum,' p. 38, (Trichius barbatus,) an insect which Mr. MacLeay himself, in his memoir on the Cetoniide of Africa, says certainly belongs to the sub-genus.

M. M. Gory and Percheron, in their monograph of the family Cetoniide, have figured an insect, which, from the emargination of the clypeus, and the want of the tufts of hair on the inside of the intermediate and posterior pair of legs, may possibly be the female of the Platygenia barbata, though it is impossible, from the rarity of specimens in collections, to determine this point by the mere inspection of a figure. The figure in Guerin's 'Iconographie,' (pl. 26, fig. 6,) seems to be copied from that given in M.M. Gory and Percheron's beautiful work. Mr. Samouelle found two specimens of a new species in a collection brought from the Gambia; he has named it after the distinguished author of the genus, whose works on the Annulosa have done so much to promote and facilitate the study of his favourite science. Both of these specimens are in the collection of the British Museum, and seem to be females, both wanting the strong spine at the base of the claws.

Head pitchy brown; clypeus in front emarginate, much and coarsely punctured, the spots decreasing in number in front of and between the eyes; the vertex quite smooth, side of clypeus at base (canthus) extended like an arch over the middle of the eye, and fringed with ferruginous hairs.

Thorar pitchy brown, lateral margin not ciliated; the sides are coarsely and much punctured, the dorsal part is very delicately and sparingly punctured.

Scutellum distinct, rounded at tip, and at base impressed transversely close to the slightly produced posterior edge of thorax, the impressed part in front punctured.

Elytra subferruginous, throughout wider than thorax; widest in the middle, towards the suture slightly raised; each elytron with eight impressed longitudinal lines somewhat arranged in pairs, none of them reaching either the anterior or posterior edge; the three inner at base not impressed, formed of an interrupted line of dots; the sides of the lines are punctured, as are the lateral margins of elytra and the tips, especially at the end of suture, which part is also clothed with short ferruginous hairs; segment between the second and third pair of legs without hairs in the middle. Apical segments of abdomen beneath with a few short hairs on the sides.

Legs and under side pitchy brown; femora compressed and punctured. Tibia, anterior dilated at tip and furnished externally with three distinct teeth, the intermediate the strongest; at the tip internally there is a strong tooth; the surface above is punctured, some of the dots being arranged in lines.

Tarsi and tibiæ of intermediate and posterior pair of legs with spinous short hairs, the posterior tibia behind the middle with a tuft of flattened spine-like hairs arranged transversely and inserted on a projecting part.

Lamarck in 1801, in his 'Systême des Animaux sans Vertébres,' first separated certain species of the Fabrician genus Cetonia, characterized by having short antennæ, terminating in a trilamellar knob-no upper lip'-membranaceous mandibles-and a straight head, with a projecting forked or bifid clypeus (Syst. p. 209). He named this division Goliathus, from the gigantic size of the typical species, first figured and described by Drury, (Illustr. I. pl. xxxi.) in 1770, and in the

they feed; in the perfect state they generally subsist on the sap of trees, at the roots of which several species are found. (Gory & Percheron, 'Monog.' p. 21 &c. MacLeay, Illustr. Annul. S. Africa,' p. 16. Stephens, 'Brit. Entom. Mandib.' iii. p. 229).
