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

 are usually found furtJier south than the preceding species *. 



A last division of the Pimelius — CRYPTOCHyLE, Lat. — is composed 

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

 the mentum covered by the prsesternum, 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 f. 



Under the generic appellation of Erodius were formerly united 

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

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

 as wide posteriorly as the base of the elytra, and terminated on each 

 side by an acute angle ; and the praesternum dilated posteriorly in 

 the manner ef a lamina or point, with its posterior extremity resting 

 on the mesosternum. 



These Erodii now form three subgenera. In 



Erodius, Lat., 



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

 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 (^encadre) in- 

 feriorly and covers the base of the maxillae. Their body is usually 

 convex \. 



ZopHosis, Lai. — Erodius, Fab., Oliv. 



Where the antennae are almost filiform or enlarge insensibly towards 

 the end, with the tenth joint very distinct from the preceding, some- 

 Avhat larger and almost ovoid, and where the anterior tibiae as Avell as 

 the following ones have no tooth near the middle of the outer side. 

 The mentum is incased (^encadre) interiorly, and covers the base of 

 the maxillce. The third joint of the antennae is hardly longer than 

 the second, and the ninth and tenth are almost turbiniform §. Those 

 of the third, or the 



Nyctelia, Lat. — Zopnosis, Germ., 



Are almost similar to the Zophoses, but the third joint of their 

 antennae is much longer than the preceding one; the following, as 

 well as the ninth and tenth, is nearly globular. The base of the 

 maxillae is exposed. Besides this, these Insects are ppculiar to South 

 America, whilst the Zophoses and Erodii are exclusively confined to
