Pachylomerus was given by Kirby to a large species of 

 Ateuchus with the anterior femora much swollen and dilated. 

 Indeed, such gigantic femora seem quite out of place on the 

 insect. 



The male differs from the female in being furnished with a 

 short stout spur on the under side of the anterior femora in the 

 centre towards the outer margin. The females appear to have 

 the under side of the anterior femora plain. The clypeus is 

 divided into three lobes, the centre one of which is 4-toothed. 



P. opacus, Lansberge, does not appear to differ hova. femoralis, 

 Kirby, in any definite particulars. 



The habits oi Pachylomerus are similar to those of Ateuchus.

This is the Scarabaus of Linnaeus and other authors. The 

 species are peculiar to the Old World, and by far the greater 

 proportion of the described species are found in the Ethiopian
