10 LAMELLICORNIA. | Copris. 
obliquely for some distance below the dung which they frequent in order 
to deposit their eggs in safety. 
Cc. lunaris, L. Suboblong, convex, of about the same size as 
Geotrupes stercorarius, entirely black, shining, with the under-side of 
head and anterior femora, and sides of the pro- meso- and metasternum 
clothed with ferruginous hairs ; head semicircular in front, with a frontal 
horn, and with a somewhat uneven raised margin, which is sharply 
incised in centre; thorax strongly reflexed in front, rather deeply 
channelled longitudinally, differing in the sexes ; scutellum apparently 
wanting ; elytra strongly striate, with the strize very feebly, and in some 
cases almost imperceptibly, crenate, interstices slightly convex, sparingly 
and exceedingly finely punctured ; pygidium visible, strongly reflexed, 
coarsely punctured ; legs black, tarsi clothed with reddish hairs.  L. 
14-20 mm. 
Male with a long pointed horn on the head, which is, as a rule, very 
slightly recurved towards apex ; at its base on the inner side are two 
small teeth, and the whole inner surface is rugose and uneven; the 
thorax is deeply excavated on both sides in front, and furnished at the 
sides of the excavation with a broad and short, but very distinct, horn, 
or horn-like prominence. 
Female with a short horn on head which is emarginate at apex, and 
the thorax very closely punctured in front with two shallow impressions 
answering to the excavations in the male, on each side of which is a 
more or less obsolete prominence ; occasionally these are almost wanting, 
and the depressions are only feebly indicated. 
The formation of the thorax is variable, and occasionally small 
specimens of the male are found which have the thorax formed as in the 
female, and the horn on the head short as in that sex; the apex of the 
horn, however, appears not to be emarginate in the male, even in these 
specimens, but always more or less acuminate ; in no case does the female 
ever present the formation of the male thorax.

ONTHOPHAGUS, Laireille. 
This genus is one of the largest in point of numbers that are found 
among the Scarabeide ; it contains upwards of three hundred and fifty 
species ; these are found chiefly in hot and tropical countries, and appear 
to be more characteristic of the Old than the New World, although this 
may perhaps be found not to be really the case; the species are distin- 
euished by their ovate and rather depressed form and almost crescent- 
shaped thorax, which is long in proportion to the elytra; the third joint 
of the labial palpi is obsolete, and the tarsal claws are distinct, and 
situated at the end of a rather long onychium.
