Rather broadly distributed and well known species, with a black 

 bifid stripe on the pale yellow abdomen, and with well-defined cross- 

 band, reaching to the hind margin of the clear wing. 



Female. Head slightly broader than the thorax. Face moder- 

 ately prominent below the antennae, partly covered with polished 

 yellowish brown (not uniformly) calli, and the rest parts densely covered 

 with rather deep yellow tomentum ; the narrow median yellow stripe 

 which is much broader than that in Chrysops mlokosietviczi, Bigot, 

 and widens out at its top just under the antennae, and which is reach- 

 ing to an itnaginate line between the very small facial deep pits which 

 is at the outer sides of the bottom part of each facial callus ; facial 

 calli at the side above hardly touching to the eye margin, and at the 

 upper end slightly reaching to the transverse sulcus just below the 

 antennae ; oral callus never devided by a yellow median line into two 

 lateral ones, and outside that a fairly narrow, oblique, yellow-tomentose 

 patch which usually extends to the eye margin and cosequently separates 

 the facial and buccal calli, but the facial and oral calli are united, and 

 the both together well figured like a letter V ; buccal calli shining 

 black or blackish, extremely large, round in shape, extending from the 

 eye margin to the lower mouth-edge, and covering the mostly parts of 

 the jowls which are covered with a witish dust only a small space 

 near eye margins below the buccal calli. Pubescence on the face very 

 few and short, whitish, almost inconspicuous, but at the yellow middle 

 line and near the eye margins slightly conspicuous, especially on the 

 former ; the pubescence on the jowls (near the mouth-edge and just 

 the below buccal calli) conspicuous, long and somewhat tawny, but not
