branch of the cubital fork ; stigma yellow ; veins mostly dark brown 

 but the stem of the cubital vein and postical vein conspicuously yellow- 

 ish ; posterior cells all widely open but the fourth cell slightly con- 

 tracting at the niargir ; anal cell closed long before the margin ; the 

 upper branch of the. cubital fork without recurrent veinlet ; discal cell 

 about as long as the second posterior cell but narrower than that. 

 Squamae rather large ; in the alar pair glassy grey with a blackish 

 margin and rather longer brown fringe which grows into the long 

 yellowish tuft at the angle ; in the thoracal pair yellowish with a brown 

 yellow margin and a very fine pale fringe. Halteres yellowish brown 

 with darker knob. 



Legs brown, with the basal half of the first tibiae, tip of the

 erior tibiae (except the apical portion) yellowish, all these colours 

 being not well defined ; front coxae ashy grey, covered with long 

 yellowish grey pubescence ; front femora blackish brown, slightly dust-

 through the whole length, at its inner margin there is a conspicuous 

 and dense fringe composed of comparatively long and blackish bristles ; 

 pubescence on the posterior femora all yellow, short and depressed, 

 but on the base of the dorsal surface and on the ventral surface there 

 are paler long erect fringes ; pubescence on the front tibiae very 

 abundant, depressed and black, and consequently the ground colour ot 

 •trie tibiae obscured by it ; on the middle tibiae depressed and yellow, 

 but on the apical half and on the whole dorsal surface with similar 

 black hairs intermixed ; on the hind tibiae similar and yellowish, but 

 with a conspicuous somewhat long and black ciliation on the dorsal 

 surface, and on the apical half or more with inconspicuous short black 

 hairs intermixed ; front tibiae about the tip and tarsi with a few scatter-
