ORDER COLEOPTERA. 453 



The Ateuchi, whose elytra have, at the external edge, 

 near their basis, strong emargination, are now, the 



Gymnopleurus, lUig. 



The four posterior limbs, are, in general, simply ciliated, 

 or furnished with small spines, and the last articulation of 

 their tarsi is as long, or longer than the preceding taken to- 

 gether. The first of the labials is dilated at the internal 

 edge, and almost triangular. The corslet has a fosset on 

 each side.* 



Other coprophagi, very analogous to the preceding, and 

 ranged also with the ateuchi, by Fabricius, are distinguished 

 from them by their intermediate limbs, the extremity of 

 which, as well as that of the last two, often dilated, or in a 

 knob, presents two spurs or spines. The hood has, in many, 

 but four or two teeth. The first articulation of the labial 

 palpi, is always larger than the following, and dilated at the 

 external side. The third and last articulation is distinct. 

 At first comes 



Sisyphus, 



Which differ from the other coprophagi in their antennae, 

 having but eight articulations, and by reason of the triangu- 

 lar form of their abdomen. The last four feet are long, 



the A, laticollis, variolosiis, semi punctatus, miliaris, sanctus, &c. of Fabri- 

 cius, and some others. See the fore-mentioned work of Mr. Macleay; 

 and the Entomography of Russia, in which some species of this sub-genus 

 and the following are perfectly figured. 



* The Ateuchi, sinuatus, pilularius, Jlagellatus, Leei, Koenigu, cuprcus, 

 profanusy &c. of Fabricius; the Sc.fulgidus, of Oliv., &c. ; the ateuchi of 

 Fabricius, which are proper to America, belong to the other sub-genera. 

 Mr. Macleay {Hor. Entom. I. part ii. p. 510) preserves still the Gymno- 

 lopleuri with the ateuchi, or his scarabsei, but he makes a division of 

 them, in which he indicates the species.
