buccate between antennae, slightly concave on middle, mouth margin 

 not produced; cheek less than half as high as eye at its lowest part 

 and gradually increasing in height posteriorly; vibrissa strong and 

 long, incurved, behind the vibrissa there is an almost equally strong 

 bristle which is upcurved and reaches almost to middle of eye. Mar- 

 ginal bristles distinct and not particularly numerous ; mouth opening 

 large, labrum slightly protruding, proboscis broad, at apex sucker- 

 like, short; palpi small, with a few weak bristles; antennae rather 

 above the average size, standing well clear of the eyes, third joint 

 pilose, broader but barely longer than second, which has on the inner 

 side at apex several distinct setulae; arista tapering, basal joints dis- 

 tinct, but slightly thickened; pubescence sparse, distinct from slightly 

 beyond base, arista in length equal to from its base to vertex ; eye 

 bare, distinctly longer than high. 



Mesonotum with posthumeral bristle strong, incurved ; three pairs 

 of dorso-centrals present ; acrostichals distinct from near anterior 

 margin, between them and the anterior dorso-central there are 3-4 

 rows of short discal setulae ; scutellum with eight marginal bristles as 

 in fontinalis Fallen, disk bare ; postnotum glossy black. 



Abdomen shorter than thorax, cylindrical in shape; second segment 

 much elongated, the others short, all segments with numerous hairs, 

 which are particularly noticeable, long and bristle-like laterally on 

 apical segments ; hypopygium rounded, large, knob-like, its surface, 

 particularly on venter, covered with numerous rather long hairs. 



Legs strong; fore tarsi gradually and distinctly dilated from base 

 to apex; mid-tibia with seven dorsal bristles (2:2:3) and 1-2 on ven- 

 tral surface ; mid-trochanter with a strong bristle ; apex of mid-meta- 

 tarsus with 3-4 end bristles ; hind femur with a series of 5-6 bristles 

 on apical half of antero-ventral surface; hind tibia with four rows of 

 hair-like bristles, one on almost the ventral surface from base to 

 apex, which is longest on middle, one rather shorter on anterior sur- 

 face which is rather longest at base, one on dorsal surface consisting 

 of 6-7 rather widely placed bristles, and a fourth much shorter on the 

 postero-dorsal surface which is regularly and rather widely spaced 

 and becomes longer toward apex; hind tarsus thickened, joints about, 

 2:3:1^ :i :2. 



Wings with costa to end of vein 3, second costal division I 2-3 times 

 as long as third; costa setulose to end of first vein; outer cross-vein 

 distinctly before the vertical line of apex of vein 2, the section of 

 vein 4 between cross-vein equal to basal section of vein 3 ; outer cross- 

 vein about half as long as section of vein 4 preceding it; last section 

 of vein 3 slightly but gradually and appreciably bent forward.
