 yellowish on the caudal margin. Pleura with the dorso-pleural area 

 light yellow extending from the pronotum to the wing-root; remainder 

 of the pleura dark brown with two white stripes, the ventral stripe 

 broad, clear-cut, beginning on the fore coxa extending to above the 

 hind coxa; dorsal stripe suffused with dusky, not clear-cut, sometimes 

 obliterated ; the brown vitta separating these two white stripes well- 

 defined. Halteres light brownish yellow passing into grayish brown on 

 the knob which is obscurely tipped with dull yellow.

 hind tibiae white, the extreme base and apex light brown; fore and 

 middle tarsi dark brownish black; hind tarsi dark brown, the basal 

 half of the first segment whitish.

 veins dark brown ; wings subhyaline ; stigma distinct, oval, brown ; a 

 vitreous spot before and beyond the stigmal spot. Venation as in fig. 

 i; Sc very short, ending far before the base of the sector, this distance 

 about equal to from one to two times the length of the sector ; Rs short, 

 only a little longer than the deflection of R4 + 5; cell ist M2 open, 

 except in abnormal specimens where it may be closed. 



Abdominal segments brown, the caudal margins broadly dull light 

 yellow. Hypopygium as in fig. 3 ; dorsal appendage of the ninth pleur-

 hook with the apex blackened ; ventral appendage prominent, the 

 apex flattened, smooth, chitinized, the ventral angle produced into a 

 slender finger-like lobe, the apex of which is blackened; the dorsal
