310 SCENOPINIU^. 



margin, just encroaching on the discal cell, and with a small 

 irregular clear space in each of the two submarginal cells ; 

 halteres with knobs wholly black. From the narrow frons and 

 the appearance of the abdomen I conclude the single specimen 

 is a d" . 



Length, 10 mm. 



Kurseong, 27. iii. 1910 (Annandale). 



Type in the Indian Museum. 



Family SCENOPINID.E. 



Head nearly semicircular ; frons and face nearly flush with the 

 eyes ; three ocelli ; epistome short, retreating ; proboscis very 

 short, labella broad ; palpi short, cylindrical, or slightly clavate. 

 Eyes bare, generally contiguous in <3 , wide apart in § ; upper 

 facets larger than lower ones in S 6 with contiguous eyes ; in 

 life the eyes with coloured bands. Antennae three-jointed, placed 

 close together at base, inserted below middle of frons ; 1st and 

 2nd joints short, 3rd elongate, strap-shaped, no style or arista. 



Thorax oblong, dorsally rather flattened, with extremely short 

 scaly pubescence on disc and minute pubescence on pleurae ; 

 scutellum broad, short, flat ; metanotum rather large. 



Abdomen flattened, 7- or S-segmented, each segment with an 

 impressed transverse line across its middle ; <5 genitalia rather 

 large and knob-like ; ovipositor concealed. 



Legs generally short, moderately stout ; tibiae unspurred, with 

 a very small bristle or two at tip ; two pulvilli, empodium reduced 

 to a bristle. 



Wings at rest lying flat on abdomen. Costa ending before wing- 

 tip, ambient vein fading away at about middle of hind margin ; 

 auxiliary vein short, ending at middle of wing ; 1st and 2nd longi- 

 tudinal veins ending shortly beyond middle ; 3rd vein beginning 

 near base of 2nd, forking rather widely at half its length ; anterior 

 cross-vein present, at about middle of discal cell ; 4th vein, forked, 

 upper branch ending above wing-tip, lower branch forming basal 

 and hinder sides of discal cell, but barely reaching wing-margin ; 

 discal cross-vein closing discal cell ;* 5th vein forked, upper 

 branch short, ending in lower inner angle of discal cell, lower 

 branch turned down rather suddenly, meeting anal vein some 

 way before wing-margin, closing anal cell ; axillary vein indistinct. 

 Upper basal cell long, 2nd short, anal cell long ; two submarginal, 

 three posterior cells ; alar squamae small, thoracic squamae almost 

 absent ; halteres normal. 



The whole body is devoid of strong bristles. 



* Lundbeck considers the discal cell technically absent, treating that space 

 as a 4th posterior cell, because he regards the 4th vein as unforked. Presum- 

 bly, therefore, he sees the posterior cross-vein in the basal portion of the lower 

 branch of the 4th vein, but he does not actually state that the posterior cross- 

 vein is present.
