1 86 Records, of the Indian Museum. [Voi.. XVI, 



The appendages in general beat a close resemblance to those of 

 A. pallidum (Selys). (vSee Rec. Ind. Mtis., VIII, pi. xvi, fig. 4.) 



Female. 



Colouring as in the male, except for the following : — 



Dorsum of segment i of abdomen black. 



Segment 2 has a broad black dorsal band running longi- 

 tudinally the whole length of the segment widening a short 

 distance before the apex of the segment, and narrowing to a point 

 at the apex. 



Segment 8 has a black dorsal mark shaped hke the head 

 of a spear, the point directed forwards, not touching either ex- 

 tremity of the segment which, like 9-10, is otherwise gray. 



Segment 9 has a basal black mark, bifid posteriorly on the 

 dorsum, occupying nearly half the length of the segment. 



Types cf 2 will be returned to the Indian Museum.

To Selys" account it may be added that in the adult female 

 specimens the abdomen is of a dull orange brown colour above; 

 black marks occur only on segments 1-2 and the extreme base 

 of 3, whilst segments 1-6 have a very fine black terminal ring and 

 7-10 are browner and darker than their predecessors.

These specimens cannot I think be separated specifically from 

 examples of A hisopa from Burma, as described by de Selys. 



The two males that I have seen are, however, characterized 

 by having a black triangle on the dorsum of the eighth abdominal 

 segment, with its apex directed towards the hinder end of the 

 segment, and extending for nearly the full length of the segment. 

 This mark does not occur so far as I know on Burmese speci- 

 mens and if constant is of enough importance to separate two 

 races.
