COLEOPTERA. 407 



usually presents two little fossulae near the middle of the posterior 

 margin. In 



Onitis, Fab. 



The second joint of the labial palpi is the largest, and the scutel- 

 lum, though very small and depressed, is still visible. The anterior 

 legs are generally longer, more slender and arcuated in the males. 

 •The tarsi are usually deficient, and the thorax, that of a small num- 

 ber excepted, is without horns(l). 



Phanjeus, Mac Leay. — Lonchophorus, Germ. — Scarabxus, L. — Co- 

 pris, Onitis, Fab. 



Where the first joint of the labial palpi is the largest and dilated 

 on the internal side. A simple sutural hiatus indicates the place of 

 the scutellum. The males differ greatly from the females in the 

 horn-like prominences of their head and thorax,* but the respective 

 length of the legs is the same. 



Several large and beautiful species of Copris, Fab., peculiar 

 to America, compose this subgenus(2). 



GopRis, Geoff. Fab. — Scarabxiis, Lin. 



This subgenus, or Copris properly so called, is at present com- 

 posed of those species only, whose antennae are terminated by a tri- 

 foliate clubj in which the four posterior tibiae are strongly dilated and 

 truncated at the extremity^ that have neither scutellum nor hiatusj 

 in which the body is always thick, and differs above according to 

 the sex, and whose labial palpi are composed of three distinct joints, 

 of which the first is the largest, almost cylindrical and not dentated 

 on the inner side. 



The largest species belong to those parts of Africa or India 

 that are situated between the tropics or in their immediate vici- 

 nity. 



C. lunaris; S. lunaris, L.; Oliv., lb., v, 36. Eight lines in 

 length; black, very glossy; the head, emarginated at the anterior 

 edge, is provided with a long horn, longer and pointed in the 

 male, short and truncated in the female — S. emarginaius, Oliv., 

 lb., viii, 64 — thorax truncated before, with a horn on each side; 

 elytra deeply striated(3).
