The twelve specimens (six of each sex) from which the 

 above particulars are taken agree with the description of 

 H. dentatithorax, except that the author does not allude to 

 the polished black space beneath the third and fourth 

 antennal joints in the ^ . The only other S. African 

 species with toothed sides to the prothorax represented in 

 the collections before me is H. curvidens, a very different 

 insect. The ? is extremely like that of H. marshalli, Gorh. 

 ( = inarmatus. Pic), the latter having the black basal portion 

 of the head reduced to two spots. Fig. 16 a ^Pl. XUI.)
