semi-longitudinal keels ; the apex at the top is stoutly 

 margined ; at the top is a triangular area, the sides with 

 stout oblique keels, meeting in the centre ; the pleura 

 coarsely irregularly reticulated, the sternum irregularly 

 transversely striolated; its side stoutly keeled with a 

 sharp margin at the edge, the pleura at the side of this 

 being hollowed ; the sternum widely hollowed, the hollow 

 becoming gradually wider towards the apex. Abdomen 

 shining, impunctate ; the base stoutly longitudinally 

 striated ; the basal ventral segment strongly reticulated ; 

 keeled down the middle to near the apex ; the other 

 segments with punctures at the apex, these being fewer on 

 the middle and more numerous on the apical segments. 



MUTILLID^E. 



Since my paper on the Indian Mutillidas (Manchester 

 Memoirs, V ., 1892) was published, some additional 

 species have come into my possession from Mr. Rothney 

 and from Col. Yerbury. The collection from the last- 

 named gentleman is of especial value, as it enables us to 

 unite the sexes of a few species. 



The discovery by Mr. Rothney of an apterous 6 Mutilla, 

 although not unique, is of interest. It is remarkable that 

 the four known apterous species of 6 Mutilla have the 

 thorax emarginate, as it often is with $ Mutillce, while it 

 never is so in the winged males.
