336. Lechria bengalensis, Brun. (PL IX, fig. 4.) 



Lechria bengalensis, Brunetti, Rec. Ind. Mus. vi, p. 301 (1911). 



c? 5 . Head blackish grey ; frons rather broad and flat, with 

 short sparse hairs ; proboscis yellowish, palpi dark. Antennae 

 black ; 1st joint of scape long, 2nd short, both broader than the 

 14-jointed flagellum, which has traces of white at the tip of each 

 joint and at the base of the 1st joint. Thorax yellowish, well 

 arched, mesonotal suture deep, posterior to which the colour of 

 the dorsum is pale livid brown, as is the scutellum ; rnetanotum, 

 blackish grey. Sides of thorax yellowish, pleurae a little dusted 

 with white. Abdomen moderately dark yellowish grey, with short 

 yellow hairs ; belly concolorous, genitalia in both sexes small, 

 brownish yellow. Legs brownish yellow, thin and long ; femora 

 with some stiff black hairs at the tip which, if viewed from 

 certain directions, give almost the appearance of two black spines ; 

 tibiae unspurred. Wings clear yellowish grey, veins distinct. 

 Auxiliary vein ending just beyond middle of wing, the subcostal 

 cross-vein at its tip ; the 1st longitudinal ending in the 2nd at 

 the point where this latter vein forks ; the 2nd vein originating 

 at or just beyond the middle of the wing, at a sharp angle and 

 turning at one-fifth of its length suddenly upward, forking 

 beyond its middle, w-here it meets the tip of the 1st vein, the 

 upper branch shorter than the lower one ; the 3rd vein issuing 

 from the 2nd at the angle in the praefurca, the anterior cross-vein 

 placed just before this point ; the latter of moderate length, 

 placed over the middle of the discal cell, which is in the middle 

 of the wing, three times as long as broad, the proximal end 

 pointed, emitting three nearly parallel veins to the wing-margin ; 

 posterior cross-vein near base of discal cell ; 5th, 6th, and 7th 

 veins nearly straight. 



Length 4 millim. 



Described from a male and three females dated respectively Pusa, 

 15. viii. 08 (type d ) ; Calcutta, 19. viii. 07 (type ? ) and 18. vi. 09; 

 Bangalore, 3000 ft., 12. x. 10 (Annandale) Pusa, 16. vii. 10. 

 Dr. Annandale has found it on tree-trunks in gardens. 



Type <5 in Pusa collection, $ in Indian Museum. 



The venation of this genus is distinctly abnormal, the only 

 previously known species, L. singularis, Skuse,* coming from 

 Australia. The 1st longitudinal vein ends in the 2nd at the 

 point where the latter forks widely, thus giving the appearance of 

 two long veins crossing one another at an angle of 45, the point 

 of contact in singularis being pnnctiform, In my species the 

 point of contact appears almost as a small cross-vein. 



* With the exception of L. lucida, Mcij., recently described from Java;
