56 STRATIOMYIDJE. 



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

 encroaching over bind margin of 4th segment. Venter yellowish, 

 with microscopic pale yellow pubescence. Leys yellow or brownish 

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

 (except at tips), and last four joints of hind tarsi dark brown. 

 Wings colourless; veins yellowish; 3rd vein forked towards tip; 

 halteres bright yellow. 



Length, 4| mm. 



Described from two $ $ 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 more broadly yellow, and three pairs of 

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

 much larger and irregularly oblong. 



Subfamily STRATIOMYINtE. 



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

 elongate, no arista. Thorax subquadrate, often only slightly 

 arched ; scutellum generally with two spines. Abdomen 5 to 6- 

 segmented, generally subquadrate, not much longer than thorax, 

 often much flattened and frequently with obvious pale markings. 

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

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

 vein with three terminations or veinlets, seldom reaching wing- 

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

cross-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 closelv 

 over middle of abdomen, leaving side-margins exposed ; alar 

 squama? small, thoracic pair large, pubescent. 



The principal characters of this subfamily taken in conjunction 

 are the subquadrate abdomen of the typical genera (Stratiomyia , 

 Odontomyia), the elongate antenna? devoid of arista, and the 

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

 segment more or less long and narrow.
