puffed out behind the eyes, where it is covered closeh- with very 

 sma'l creamy orange scales. Mouth border whitish, bare. 



Thorax. — Dorsum dusky olive-l)rown, with two faint but dis- 

 tinct, narrow, widely separated blackish lines. Anterior part and 

 sides with pubescence as in niveiventris , except that it is whitish 

 below the posterior calU. Scutellum as in nivsiventris. 



Ahdomoi as in niveiventris. The genital organ is concealed 

 within the body, but is covered with whitish shimmer and fine black 

 bristles, its tip apparently consisfng of a pair of rather complex 

 orange-coloured claspers ; the upper side of the tip being covered 

 with thick, black, bristly spines. 



Legs. — The under side of the fore femora is pale, and the spines 

 below the hind tarsi less conspicuous. 



Wings wholly very pale grey, including costal cell. The 

 veins in the middle at the base of the wing are pale orange, as are 

 also the subcostal, third and fifth longitudinals. Halteres cream 

 colour. 



Described from a single example taken by Dr. Annandale in 

 company with niveiventris 9 , of which species I conclude the 

 present specimen is tlje & . The frons is barely appreciably nar- 

 rower, therefore the narrowness of the back of the head above, 

 the difference in shape of the genital organs, and the nearly clear 

 wings are the only points in which it materially differs from the 

 previous!}' described species.
