brown band across the middle of tliis cell ; the borders of the 

 discal cell and the 5lh longitudinal vein narrowly suffused with 

 brown. The veins api)ear generally liable to a slight sutfusion, 

 and the hinder part of the wing is a little darker grey distally, 

 Halteres ^^ellowish with brown tips. 



Length 3| millini. 



Described from a female in the Indian Museum collection, 

 dated 30. vii. 10 (no locality given, but probably Assam), and one 

 in my own collection from Peradeniya, Ceylon, xii. 07 ; in the 

 former specimen both the hind legs are missing. 



The wing agrees perfectly with van der Wulp's plate. The 

 antennae and abdomen in his type specimen were injured and he 

 described the male only. Of the antennae, the first three joints 

 (not two, as he says *) are yellow, joints 4 to 8 yellow with 

 brownish marks, or wholly brownish, 9 and 10 quite black, 11 

 and 12 yellowish white, 13 to 16 quite black, the 16th with a short 

 white style. The two basal abdominal segments are mainly dirty 

 yellowy with black posterior borders, tlie remainder being brownish 

 yellow with broadly black borders ; the apical segments wholly 

 blackish. Belly similar. The palpi are black. Wulp described 

 his male from Java.

 the first and the infuscated wing-tip ; the clear space immediately 

 adjoining the infuscated wing-tip encloses a pale blackish oblong 

 spot placed lengthwise on the costa; outer side of the discal cell 

 with a black suffusion ; a black round spot in the 1st basal cell ;
