ERIOPTERA. 451 



brown, with pale yellow hairs at the sides ; segments considerably 

 emarginate ; belly similar. Grenitalia brownish yellow ; a large 

 basal stout subovate pubescent joint, with moderately long bifid 

 yellow claws at the tip. Legs yellow, tibiae a little tinged with 

 brown. Wings nearly clear, pubescence on the veins very incon- 

 spicuous. Venation nearly normal ; lower branch of the 4th 

 longitudinal vein forked widely at half its length; posterior 

 cross-vein at some distance before the fork of the 4th vein ; the 

 7th vein short, turning down to the margin of the wing imme- 

 diately after quitting the proximity of the 6th vein. Halteres 

 yellow, clubs black. 



Length 4 millim. 



Described fcom a single male taken by Dr. Annandale at 

 Pallode, near Trivandrum, Travancore State, South India, 

 15. xi. 08. 



Type in the Indian Museum. 



This species resembles E. halterata in general appearance, 

 especially in the black-clubbed halteres. It is, however, easily 

 distinguished by several apparently good characters : by the 

 inconspicuous pubescence of the veins ; the ferruginous shining 

 thorax, lightly though distinctly striped with black ; the different 

 position of the posterior cross-vein ; the short 7th vein turning 

 down somewhat sharply to the margin instead of running parallel 

 with it for a considerable distance, as in E. halterata. Also the 

 fork of the lower branch of the 4th vein is different, lying beyond 

 the middle of the vein, and being widely open, with the veinlets 

 quite straight. 



322. Erioptera distans, sp. nov. 



c? . Head dark grey ; frons very broad, three-fourths the width 

 of the head, and with long black hairs. Proboscis, palpi, and 

 antennae brownish yellow ; flagellar joints oval, moderately large 

 and long, distinctly elongate towards the tip. Thorax : dorsurn 

 wholly blackish, a little greyish below the shoulders and in front ; 

 sides dark grey, with a little grey dusting. Abdomen : the 1st 

 segment pale dirty yellow, the remainder black. Genitalia some- 

 what concealed by a pair of large blackish curved plates; yellowish, 

 two-jointed, hairy, with two small filamentous appendages and an 

 upper pair of small brownish yellow subconical organs. Leys 

 brown, with much longer pubescence than usual, especially on 

 the femora. Wings pale grey ; pubescence very inconspicuous 

 but distinctly present. The auxiliary vein ending opposite the 

 beginning of the 3rd vein ; the subcostal cross-vein at a little 

 before the tip of the auxiliary vein ; the 1st longitudinal vein at 

 its tip, indistinct, where the wing is a little darkened, as through 

 the beginning of a stigma ; remainder of venation normal ; the 

 lower branch of 4th longitudinal vein forking rather early ; the 

 posterior cross-vein half-way between the fork of the 4th vein
