projection in the form of a ligula. The mentum is emarginated. 

 The sternum exhibits no particular prominence, and the hooks of the 

 tarsi are always simple. The anterior tarsi are frequently wanting 

 in several, either ab ovo or because they are deciduous. 



The length of the alimentary canal is always very great ; occa- 

 sionally (as in Copris lunaris) ten or twelve times that of the body. 

 The chylific ventricle occupies the largest portion of it, is studded 

 with conoid papillae, is closely folded together and kept in this state 

 of agglomeration by numerous tracheal bridles. The intestine is 

 filiform, and terminates by an inflation. The testes of the Copro- 

 phagi, dissected by M. Dufour, appeared to him to consist of six or- 

 bicular, slightly depressed spermatic capsules, usually united by tra- 

 cheae in one bundle, each placed on a tubular and tolerably long 

 pedicle, which terminates in a short vas deferens. There is but one 

 pair of vesiculae seminales ; they are very long, filiform, and in nu- 

 merous folds. 



This first section corresponds to the third division of the genus 

 Scarabaeus, Oliv., or to that of Copris, but with the addition of some 

 of the Scarabaeides — Aphodiiis — of that naturalist. 



In some, the two intermediate legs are more remote at base than 

 the others ; the labial palpi are very hairy, with the last joint much 

 smaller than the others, or even indistinct ; the scutellum null or ex- 

 tremely small, and the anus exposed. 



Coprophagi of this division peculiar to the eastern continent, with 

 a rounded body, usually depressed above or but slightly convex, simi- 

 lar or but little different, and without horns in both sexes; in which 

 the antennae of nine joints terminate in a foliaceous club ; without 

 scutellum, or sutural hiatus indicating its place ; in which the four 

 posterior tibiae, usually furnished with ciliated or hairy fringes, are 

 slender, elongated, not dilated at the extremity, or but slightly so, 

 truncated obliquely, and terminated by a single stout and spiniform 

 or acuminated spur ; and finally, in Avhich the epistoma is more or 

 less lobate or dentated, form the genus 



Ateuchus, Web. Fab., 



Since, however, restricted to those species in which the exterior 

 margin of the elytra is straight, or unemarginated and without a 

 sinus near their base exposing the corresponding portion of the 

 superior margin of the abdomen. The tibiae and tarsi of the four 

 last legs are furnished with long hairs ; the four first joints of the 

 tarsi are generally longer than in the others. The first joint of the 

 labial palpi is nearly cylindrical, or in the form of a reversed cone. 

 The epistoma is most commonly divided into three lobes or festoons, 

 and its contour presents six teeth. 



These Insects which M. Mac Leay, Jun., in his ingenious Horce 

 Entomologicce, I, p. 184, designates by the generic appellation of 

 ScarabcBits, as being the name originally bestowed upon them by the 

 Latins *, and of which in the same Avork — part II, p. 497 — he gives 

 an excellent Monograph, conceal their ova in balls of dung, and even
