N0 - 3622 STRATIOMYIDAE — JAMES 13 



head width, frons narrowing gradually to 0.14 head width at callus, 

 then widening onto face; frons above callus and vertex shining, with 

 very sparse, microscopic white hairs; lower part of frons and face, 

 particularly facialia, densely white tomentose, becoming somewhat 

 yellowish below. Flagellum large, 1.5 as high as long, kidney shaped 

 from inner view; apical half of flagellum blackish; arista black; 

 antennae otherwise yellow. Proboscis brownish black with concolorous 

 hairs. 



Mesonotum with appressed brassy-yellow hairs, well distributed 

 but relatively sparse and not conspicuous; supra-alar prominences 

 and scutellum except base with similar black hairs; posterior bulge 

 of mesopleuron and sternopleuron with scattered semi-erect white 

 hairs, rest of mesopleuron and pteropleuron bare and shining. Scu- 

 tellum (fig. 20) overall triangular, the effect accentuated by the 

 distinctly margined, slightly upturned, flattened apical part, which 

 takes in about one-third the length of the scutellum; entire sides of 

 margined area beset with microdenticles. Legs wholly pale yellow, 

 the femora on apical half slightly tending to brownish yellow. Halteres 

 yellow, brownish on basal part of knob. Wings hyaline; heavier veins 

 yellow, brownish on basal half; venation similar to that of Meristocera 

 laticornis (fig. 15), but all veins except part of M separating discal 

 cell distinct throughout; R2+3, however, distinct throughout, though 

 feeble, and branching from R 8 at cross- vein; cross- vein r-rn distinct 

 but short; anal cell narrower than combined width of basal cells; 

 and R 8 more strongly evanescent at base. More than half of anal cell 

 clothed with microtrichia. 



Abdomen gradually expanding to base of third segment, thence 

 rounded; area of denser punctures extending to apical part of fourth 

 tergum, the fifth and sides of third and fourth broadly shining; venter 

 with first sternum and sides of second densely punctured. Ovipositor 

 yellow. Length 2.50-2.75 mm.
