segment dull yellow, the sternites similar with about the apical two- 
thirds dull yellow. 
Habitat. — Java.

From the other described species with white tarsi, D. alhitarsis 
difi'ers as follows: D. saltens Doleschall and cuneiformis do Meijere 
have subcosta short, endmg before the origin of the radial sector. 
D. longivena Edwards ^ has the subcosta long but is a much smaller 
msect (wmg 5 mm. mstead of 9 mm.). D. Jcohusi de Meijere ^ has the 
tibiae white with black rings, the radial sector short, oblique, cell 
1st M2 of the wmgs lackmg, etc. D. novae guineae de Meijere^ is 
larger, the tibiae paler, the venation quite different in the very short 
subcosta, the shorter radial sector and the position of cell 1st M^. ■ 
DICRANOMYIA ATRESCENS, new species. 
Body-coloration dark slate-gray; wings subhy aline with the 
stigma brown. 
Male. — Length, 6.3 mm.; wing, 7.2 mm. Head dark brownish

Abdomen concolorous with the thorax; the pleurites of the hypo- 
pygium small, cylindrical; the ventral lobe large, almost globular, its 
inner margin produced entad into a sharp conical point that is fringed 
with long hairs along the caudal margin; the lobe itself is provided
