36 STRATIOMTID.i;. 



1 have not seen the male with certainty, and the follo\\ mg notes 

 are from Gerstaecker's deseriptioa oi: that sex. Very distinct from 

 2 , much smaller. Head considerably broader than thorax, deep 

 black, with one white hair-spot ahove antennae ; the latter with 2nd 

 scapal joint and lirst two annulations of 3rd joint reddish jellow, 

 rest black. Thorax with ground-colour dark blackish brown, side- 

 margins and two very indistinct median stripes of emerald-green 

 scales. Scutellar spines, especially middle pair, mucli longer than 

 in 5 and mainly reddish ^yellow. Abdomen deep black, with paler 

 sides, white spots as in $ , but posterior ones absent. Wimjs as 

 in 5 , pale spot on inner border absent. 



A S from Coorg, S. India, in the Pusa collection, may be this 

 species: also a S from Pashok, Darjiling, 200U ft. 11. vi. 1916 

 (Z. C. Ifa7'tless), though neither of them agrees quite with 

 Gei'staecker's description.

Genotype, Stratiosphecomyia variegata, Brnn. 



Head flattened, semicircular, narrower than greatest width of 

 thorax, nearly bare ; occiput not at all projecting behind eyes ; 

 ocelli on small, very distinct prominence, equidistant; eyes in S 

 quite contiguous for a moderate distance, hinder and lower facets 

 distinctly smaller than anterior and upper ones. Proboscis thick, 

 apparently moderately long but mainly concealed \^ithin the 

 mouth-opening, probably producible; pal[)i elongate, a little 

 pubescent, apparently of one joint only. Antenna? elongate, 

 nearly filiform, two-thirds as long as head and thorax together ;, 

 1st joint about twice as long as broad, 2nd about half this length ; 

 flagellum with eight distinct annulations, subequal, except the 

 last which is rather longer and pointed. Thorax approximately 

 oval, widest at level of wings, only slightly arched ; microscopically 

 pubescent here and there. Scutellum of n)oderate size, semi- 

 circular or subtriangular, unspined. Abdomen with a little soft 

 pubescence towards sides at base, apparently 5-segmented, the 

 emargination between the 2nd and 3rd segments extremely in- 

 definite, possibly these forming but a single segment ; the 1st very 

 short, transvei'se, 2nd as wide as 1st at base, tlience suddenly 

 narrowing at half its length to cylindrical form, the 3rd at base 

 as wide as tip of 2nd, rapidly widening to tip; the abdomen 

 widening to tip of 4th segment, thence rapidly narrowing, the tip 

 rounded, the 2nd to the 5th segments subequal in length. 

 Genitalia exposed, fairly complex, consisting of a dorsal plate and 

 a pair of two-jointed hairy claspers, with apparently at least one 

 other pair of appendages. Legs quite slender, moderately long,, 

 minutely pubescent ; hind legs longer and slightly stouter, hind 

 femora barely thickened towards tips, hind metatarsi distinctly
