men, and more strongly granulated elytra, on which the two 

 inner elevated lines are almost effaced. 



In other species, Trachyderma, Lat., the abdomen is propor- 

 tionally narrower and mdre elongated, and frequently much com- 

 pressed laterally; the legs are long, and the tibise, the anterior ones 

 not excepted, slender, narrow, and terminated by small spurs. They 

 are usually found further south than the preceding species(l). 



A last division of the Pimeliae Cryptochyle, Lat. is composed 

 of species in which the body is relatively shorter or more thick-set, 

 the mentum covered by the presternum, and the antennae are ab- 

 ruptly terminated by a club, divided into two parts, one formed by 

 the ninth joint and the other by the two following ones, which are 

 confounded together. These species appear to be concentrated in 

 the southern extremity of Africa(2). 



Under the generic appellation of Erodius, were formerly united 

 certain Pimelarie, closely allied to the preceding ones, but in which 

 the body is ovoid, short, arcuated or gibbous above, the thorax 

 short, as wide posteriorly as the base of the elytra, and terminated 

 on each side by an acute angle; and the presternum dilated poste- 

 riorly in the manner of a lamina or point, with its posterior extre- 

 mity resting on the mesosternum. 



These Erodii now form three subgenera. In 



Erodius, Lat. 



Or Erodius properly so called, the two last joints of the antennae 

 are united and form a small globuliform club, the anterior tibiae 

 have a stout tooth near the middle of their outer side, and another 

 on the same side at the extremity, and the mentum is incased (en- 

 cadre) infenorly and covers the base of the maxillae. Their body is 

 usually convex(3).

Where the antennae are almost filiform or enlarge insensibly to- 

 wards the end, with the tenth joint very distinct from the preceding, 

 somewhat larger and almost ovoid, and where the anterior tibiae as
