402 TIPULID.E. 



Genitalia of male consisting mainly of a very large pair of hairy 

 yellow fleshy bifid claspers, snrmounted by a pair of small black- 

 tipped hooks ; a small palp-like organ emerges from below the 

 ultimate segment of the abdomen ; these organs are not enclosed 

 by any protecting plates or sheaths. In the female the ovipositor 

 consists of a rather larger upper conical piece, ending in two 

 comparatively small sheaths, and below this a pair of shorter 

 smaller organs, which also terminate in a pair of hard chitinous 

 sheaths ; the upper piece bears a pair of peculiarly curved bristles 

 directed backwards. Legs dark brown, basal part of femora pale, 

 and also broadly pale beyond the middle, leaving a moderately 

 wide black ring at tip. Wings nearly clear ; a brownish square 

 stigma at tip of 1st longitudinal vein ; base of prsefurca very 

 slightly suffused ; veins black. Halteres with the stem pale, 

 considerably pubescent ; knob black, bare. 



Length 5 millim. 



Described from several specimens in th^ Indian Museum from 

 Calcutta (September to February), where it is not uncommon, 

 and Katihar, Bengal, 7-31. viii. 10. I have seen it from Madhupur, 

 Bengal, 13. X. 09 (Paiua), and it is in the Pusa collection from 

 Pusa, 18-20. ii. 08 (on moss) and ix. 07.

Described from several examples in the Indian Museum taken 

 at Kurseong by Dr. Annandale, 3-5. vii. 08 and 18-29. vi. 09, when 

 he found it common amongst ferns and low herbage, often entering 

 houses at night, attracted by a light.
