russet; middle and hind tarsi buff, last joint and tips of 

 remaining joints dark brown. 



Angola : type and five other specimens from Bihe, No- 

 vember-December 1904 {Dr. F. Creiyhton IVellman) ; a sixth 

 specimen from Benguella, 1905 [Dr. F. C. IVellman). 

 Dr. Wellman's field-note on this species states : — " About 

 60 specimens in plains and edges of bush, 300 miles from 

 coast. Active." 



H. inflaiicornis is sufficiently distinguished from its African 

 congeners at present known by the broad grey lateral border 

 to the abdomen. In the case of one specimen in Dr. Well- 

 man's series, on the third and following segments there is a 

 dark mark in the grey border on each side, Avhich would 

 appear to indicate that the border has been produced by the 

 fusion with the grey lateral edging of a dorsal series of 

 paired grey spots.
