transverse band placed on base of 5th segment, the middle part 

 encroaching ovt-r hind mai-gin of 4th .segment. Venter yellowish, 

 with microscopic pale \ ellow pubescence. Leys vellow or brownish 

 yellow j front tarsi wholly, apical half of middle pair, hind tibiae 

 (except at tips), and last, four joints of hind tarsi dark brov\n. 

 Winc/s colourless; veins yellowish; 3rd vein forked towards tip; 

 lialteres bright yellow. 



Lengthy 4| mm. 



Described from two 5 5 from Abbottabad, N.W. Frontier 

 Province, vi. 1916 {Fletcher). 



Type sent to the British Museum ; co-type in Pusa collection. 



The abdomen might equally well be described as black with the 

 base narrowly and tip moi'e broadly yellow, and three pairs of 

 yellow side-spots, the first pair triangular, the 2nd and 3rd pairs 

 much larger and irregularly oblong. 



Subfamily STRATIOMYINiE. 



Head short, rather flattened in front ; antennas with 3rd joint 

 elongate, no arista. Thorax subquadrate, often only sliglitly 

 arched; scutellum generally with two spines. Abdomen 5 to (>- 

 segmented, generally subquadrate, not much longer than thorax, 

 often much flattened and frequently with obvious pale markings. 

 Legs of moderate lengtli and strength, or somewhat weak. Wings 

 with 3rd vein generally forked, ending far before wing-tip; 4ih 

 vein with three terminations or veinlets, seldom reaching v\ing- 

 margin, one or more often absent or extremely weak ; posterior

ci'oss-vein present, so that the 5th vein never forms any part of 

 the discal cell; anal cell closed near wing-border; 5 posterior 

 cells, united on wing-margin. Wing in repose folded (•h)Sely 

 over middle of alidomen, leaving side-maigins exposed; alar 

 squamae small, thoracic pair large, pubescent. 



The principal cha'-acters of this subfamily taken in conjunction 

 are the subquadrate abdomen of the typical genera {Stratiomyla, 

 Odontomyia), the elongate antennae devoid of arista, and the 

 presence of the posterior cross-vein. Larva peripneustic, last 

 segment more or less long and narrow.
