and the apterous division. The genera with tarsi on the fore-legs are : 
Aulacmm, Dej. {Mintophilus, Lap.), including the only known New 
Holland species, A. carinatum, Reiche {Aid. Hollandice, Hej.) ; Coprce- 
cus, Reiche, differing from the preceding by the simple rounded posterior 
angles of the thorax, is not yet sufficiently defined, as the specimen of 
the C. hemisphcBricus, Peron (from New Holland), in the Paris collection, 
according to Latreille and Guerin, wants the antennas and parts of the 
mouth ; Tessarodon, Hope {At. hollandice, F.), only known to the author 
from Hope’s plate, and placed here conjecturally. In the others, the 
anterior tarsi are wanting : Circellium, Latr. {A. Bacchus, F.) ; Eucra- 
nium, Dej.; Glyphiderus, Westw., which has two — Pachysoma and 
Mnematium, MacL., having a single spine on the intermediate tibiae. 
Westwood (Proceed. Ent. Soc. p. 51) has made known two new New 
Holland genera of Ateuchidce. Cephalodesmius ; clypeus in medio 
4-dentatus, dentibus intermediis valde elongatis, prothorax magnus 
8-angularis, pedes valde elongati, tarsi antici distincti, breves : C. 
armiger. Temnoplectron ; clypeus in lobos duos minutos obtusos pro- 
ductus, prothorax lateribus rotundatis (et cum elytris subcontinuis) 
antice parum angustior; tarsi antici minuti; ungues subtus denticulo 
instructi : T, rotundum, from Melville Island. To the genus Tessero- 
don {At. Hollandice, F.), he adds two species, T. angulatus from 
Swan River ; and T. piceus from Port Essington ; the latter is also 
described by Hope (Proceed. Ent. Soc. p. 44). 
Westwood has also (Proceed. Ent. Soc. p. 58), pointed out some new 
genera of the same family : Arachnodes and Nanos, however, alone 
belong to the Ateuchidce, both formed at the expense of Epilissus, Dej. ; 
the former {Circ. nitidum, Lap.), with the mentum not emarginated, 
slender labial-palpi, sides of the prothorax angular and reflexed ; long 
legs, and the last tarsal joint running out to a small spine ; Nanos {Give, 
pygmeeum, Lap.), mentum strongly emarginated, labial-palpi very short 
and thick, sides of the prothorax rounded, shorter legs, and crooked tibias. 
The following belong to the real Copridee, having tibiae broader 
towards the end, and the tarsal joints of the hind legs gradually 
narrower : Macroderes, almost hemispherical, with emarginated clypeus, 
very large prothorax rounded at the sides ; the type is Onthophagus 
Greenii, Kirby ; Uroxys, oblong, somewhat flat, clypeus sharply 2-lobed 
anteriorly, sides of prothorax angular in the middle, elytra pointed 
posteriorly, elongated fore-legs, and (in the one sex) tibias angular 
internally ; U. cuprescens from Columbia. 
Westwood has mistaken the genus Scatonomus of the reporter ; 
both the species mentioned by him, 8c. myrmidon {Onth. myrmidon, 
Lacord.) from Cayenne, and 8c. smaragdinus from Brazil, belong ta 
Onthocharis, Dej., from which 8catonomus is essentially very different. 
Anomiopiis, with two new Brazilian species, A. virescens and nigricans,
