DASIMALLOMTIA. 495 



separated above by a hairy frons, less than one-third the width of 

 the head, contiguous below for a short space. Antennae missing, 

 except the scape, which is normal but rather less in size, and the 

 three basal joints of the flagellum, which also have every appear- 

 ance of normality, being rounded and verticillate. Abdomen 

 narrowed at base, widened beyond the middle ; genitalia of 

 moderate size, normal. Legs conspicuously pubescent throughout 

 with moderately long hairs. Wings moderately broad, anal angle 

 rounded but distinct ; two submarginal cells, four posterior cells ; 

 discal cell open, being coalescent with the 3rd posterior cell. 

 Auxiliary vein lying close to 1st longitudinal, ending at about the 

 middle of the wing, the 1st longitudinal ending a little beyond : 

 the 2nd longitudinal beginning at one-third of the wing, forked ; 

 marginal cross-vein just before tip of 1st vein ; the 3rd vein 

 beginning a little before the fork of the 2nd ; the 4th forking 

 close to the anterior cross-vein, both branches forked ; posterior 

 cross-vein just beyond fork of 4th vein ; 3rd posterior cell pointed 

 at base, 6th and 7th veins slightly sinuous. 



Range. Darjiling district. 



Although this genus stands out as quite distinct from others, it 

 is difficult to define its peculiar characters. Perhaps the robust- 

 ness of the body (affording some general resemblance to Teucho- 

 labis), the narrowed abdomen near the base, and especially the 

 somewhat shortened, thickened, very hairy legs, are the best 

 distinguishing features from Gnoplwmyia, Os. Sac., which seems 

 to be its nearest Eastern ally.

5 . Head : frons forming one-fourth the width of the head, 

 grey, with some long, rather shaggy yellow hairs ; back of head 

 similar. Proboscis brownish yellow, short, rather stump-like; 

 palpi normal, elongate, four-jointed, pubescent. Antennae with 

 apparently two scapal joints nearly alike, rather short, slightly 

 wider at the tip, the flagellar joints oval (only three are remaining, 

 the rest being broken off) ; scape dark, flagellum brownish yellow. 

 Thorax : dorsum yellowish ; a moderately broad, very shining 

 black stripe in the middle from the anterior margin to the suture, 

 slightly narrowed in front ; a short, very shining, black stripe on 

 each side of the median one, with an isolated black spot in front 

 of it near the shoulders ; behind the suture, near the dorsal 

 margin on each side is a very black shining triangular spot, and 

 on the dorsum (behind the suture) a pair of normal wide blackish 

 stripes reaching to the scutellum, which latter is small and yellow, 

 with the base a little blackish. Sides of thorax with a pinkish 

 tinge ; some short yellow hair on the pleura? and near the wing- 

 roots ; metanotum blackish. Prothorax moderately large, produced 

 into a short stout neck. Abdomen black, roughened; posterior
