spot, which is contracted in the middle hehind and does not reach 

 the sides of the segment except at the extreme base, where it joins 

 a hiroe livid spot on the same segment oF the venter. Lens all 

 black and bare. Wings grey, yellow at base, a yellowish-brown 

 suffusion from the centre of the costa reaching half-way to the 

 posterior border, and a similar suffusion at the wing-tip extending

Described from one $ in the Indian Museum collection, from 

 Mungpliu, Sikldm District. 



This species bears a considerable general resemblance to 

 V. peUucens, L., of Europe, but in that species the wliole of the 

 2nd segment is livid yellow, this colour passing over the sides 

 of the segment in its full width, whereas in hasalis it is 

 narrowed to the extreme base of the segment ; also in pelhicens 

 the sides of the thorax along their upper edge are always brownish- 

 yellow, of which there is no trace in hasalis ; moreover, the 

 scutellum in ijelluceus is bright tawny, whereas in hasalis it is 

 nearly black.
