450 TIPULIDJE. 



almost imperceptibly black. Wings yellowish, with numerous 

 dark brown marks ; pubescent, along the veins, the hairs normally 

 yellow, especially along the bright yellow costa, but the hairs 

 are black here and there, forming the dark wing-spots. The 

 auxiliary vein and the 1st longitudinal lie so near the costa as 

 to be hardly visible ; the 2nd longitudinal vein beginning at one- 

 third the length of the wing, forking beyond the middle, the 

 upper branch forming a rectangle at its origin, both branches 

 running parallel with the margin of the wing ; the very short 

 marginal cross-vein placed at the angle in the upper branch ; the 

 3rd longitudinal vein beginning near the middle of the wing, its 

 basal section in a line with the anterior cross-vein, which itself 

 joins the pointed basal end of the 2nd posterior cell ; the 3rd 

 vein and the upper branch of: the 4th longitudinal exactly 

 parallel ; the lower branch of the 4th vein forked just before 

 its middle ; posterior cross-vein situated just beyond the middle 

 of the wing, in a line with the anterior cross-vein ; the 5th, 6th 

 and 7th veins practically straight. The wing-markings are com- 

 posed of small patches of black hairs, and are distributed in the 

 following manner : five small spots on the costa, a 6th being at 

 the tip of the lower branch of the 2nd longitudinal vein ; also one 

 at the tip of all the veins posterior to, but not including, the 3rd 

 vein ; an elongated spot over the cross-veins and one each over 

 the fork of the 2nd vein, and that of the 4th vein ; the 3rd vein, 

 for some distance in its middle, bears black hairs ; similar black 

 hair-spots occur here and there with apparently more or less 

 irregularity. Halteres brownish yellow. 



Length 2| millim. 



Described from two females taken by Dr. Annandale at 

 Kurseong, 26-27. vi. 10. 



Type and second specimen both in the Indian Museum. 



Kather easily distinguished from all other species by the black 

 hair-spots giving the wing a spotted appearance. 



321. Erioptera ferruginea, sp. nov. 



cj . Head : vertex and upper part of back of head shining light 

 reddish or ferruginous brown ; frons, which is rather narrow 

 less than a third of the width of the head and lower part of 

 head behind the eyes, yellow; post-ocular orbit silvery white. 

 Antennal scape and base of flagellura yellowish ; remainder of 

 flagellum brown. Proboscis yellow, palpi brownish. Thorax light 

 ferruginous brown, very shining ; dorsum with a narrow black 

 line in the centre, very attenuated towards the anterior margin, 

 which it barely reaches; it also does not continue posteriorly 

 beyond the suture. Some bristly hairs on the dorsum give the 

 appearance of the usual two well-separated rows of dorso-central 

 ones. Scutellum and sides concolorous or a little lighter ; metano- 

 tuin not shining. Abdomen bright yellowish, almost ferruginous
