is distinguished with difficulty from Onthochwris, by the very broad 
hind legs ; at least, in the Berlin collection, I have a series of species be- 
fore me, in which a gradual transition is found in the hinder tarsi, from 
the broadest form, as in the Anomiopus, to the narrower, as existing in 
the 0. myrmidon. 
The genus Buhas, Meg., has been distinguished from Onitis, by Mul- 
sant (Col. Fr. p. 76), from having no scutellum, nor any free space 
in place of it ; the first joint of the labial-palpi not smaller than the 
second, the body tolerably convex, and the prothorax forming projections 
anteriorly ; the species are 0. bison, F., and bubalus, 01. 
Hope has described some new species of Copridw from Western 
Africa (Ann. Nat. Hist. ix. p. 494) : Gymnopleurus hilaris, Iwtus, and 
Heliocopris Diance. 
The New Holland Fauna has been enriched with eleven species of On- 
thophagns, five from Port Essington by Hope (Proceed. Ent. Soc. p. 43), 
and six from Van Diemen’s Land* by the reporter (Arch. 1842, i. p. 154). 
The presence of the genus Copris in New Holland, appears to be con- 
fined to the north coast. Hope (Proceed. Ent. Soc. p. 44) describes a 
species, C. glahricollis, from Port Essington, and mentions that he is in 
possession of three other species from Melville Island. 
The AphodiidcB have been divided by Mulsant (Col. Fr. p. 160, &c.) 
into two divisions, and the number of genera increased. The first divi- 
sion, Aphodiarii, with narrow hinder tarsi, and distinct claws upon them, 
is separated into three sub-divisions : — 1. Aphodiatoe, has normally the 
strias on the elytra with simple interstices, the head flat or slightly 
convex, half-six- angled or semicircular, and then slightly emarginated 
anteriorly; well developed membranous maxillary lobes. 1. Colohop- 
terus ; elytra truncate, not completely covering the pygidium; A. erra- 
ticus. The following genera (2-6) have the clypeus laterally dilated 
before the eyes. 2. Coprimorphus ; first joint of the hind tarsus as 
long as the four following put together ; A. scrutator. 3. Eupleurus ; 
scutellum long, back of the elytra flat; A. subterraneus. 4. Otophorus ; 
scutellum long, back of the elytra convex, dilatation of the sides of the 
clypeus forming a right angle ; A. hcemorrhoidalis. 5. Teuchestes ; like 
4, only the dilatation of the sides of the clypeus is rounded; A.fossor. 
6. Aphodius ; scutellum short; A. scrybalarius, conjugatus, fcetens, 
fimetarius, rithms, Dej.; alpicola, new species, from Savoy; vernus, 
new species, from the South of France ; ater, granarius, bimaculatus, 
plagiativs, ^L-maculatus, tristis, exiguus, new species ; pusillus, Hbt. ; 
monticola, Dej., new species ; hydrochceris, F. ; sordidus, F. ; lugens, 
Cr. ; immundus, Cr. ; nitidulus, F. ; merdarius, F. ; ferruginous, Dej., 
* One of these has been called 0. hirculus, a name under which a species, 
abundant in Brazil, has been described by Mannerheim, and which must 
therefore be altered.
