PENTODON CONTBACTUS. 11 



smooth, the former having a broad median impression, 

 the legs are thick, the anterior tibiae have two very stout 

 teeth on the outer edge and one at the apex, the inter- 

 mediate and posterior tibiae have the apical margin and 

 two transverse ridges on the outer side armed with small 

 spines. The length of the body is 1518 millm.

Found throughout Caffraria (' Insecta Caffrariae.').

This species is very similar to the preceding, but is of 

 a rather smaller size and of a duller black above, the 

 head is less closely punctured in the middle and smooth 

 at the base and apex, with the transverse line almost 

 obsolete, and the apical margin of the clypeus more 

 strongly reflexed and without points, the basal margin 

 of the thorax is straighter, the scutellum is smaller, 

 and the elytra are shorter and more rounded, with the 

 rows of punctures more regular, and the interstices 

 slightly convex. The length of the body is 12 14 millm. 



Both the foregoing species of Pentodon have been 

 forwarded as Wheat-pests, which are believed to be 

 similar in their mode of attack to the Heteronychus 

 arator. As the two genera are closely allied, their habits 

 are probably similar. Both the species of Pentodon are 

 to be easily distinguished from H. arator by their larger, 

 more ovate and convex form and duller colour. 0. E. J. 



Occurs in the region of the Eiver Limpopo (' Insecta 

 Caffrariae.').
