yellow. Halteres brown. Legs, femora brown, somewhat darker at 

 the tip; tibiae brown; fore tarsi with the basal two-thirds of the 

 metatarsus brown, remainder white, hind tarsi entirely white. Wmgs 

 infumed with darker, the tip brown, a narrow brown seam on r, veins 

 dark brown; venation: (see pi. 42, fig. 1), Sc endmg far beyond the 

 origin of Rs, Sc^, about three times as long as /Scg, Rs about three 

 times as long as the deflection of R^+^. 



Abdominal tergites dark brown with about the apical half of each 

 segment dull yellow, the sternites similar with about the apical two- 

 thirds dull yellow. 



Habitat. — Java. 



Holotype. — Tjibodas, Mount Gede, Java; altitude, 4,500 feet 

 (Bryant and Palmer). 



Type.—Cfit. No. 19007, U.S.N.M. 



From the other described species with white tarsi, D. albitarsis 

 differs as follows: D. saltens Doleschall and cuneiformis de Meijere 

 have subcosta short, ending before the origin of the radial sector. 

 D. longivena Edwards ^ has the subcosta long but is a much smaller 

 insect (wing 5 mm. instead of 9 mm.). D. Tcobusi de Meijere ^ has the 

 tibiae white with black rings, the radial sector short, oblique, cell 

 1st il/g of the wmgs lacking, etc. B. novaeguineae 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 J/g. 



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 

 black, the mouth parts injured. 



Color of the thorax dark slate-gray with a sparse brown bloom. 

 Halteres brownish black. Legs dark brown, the femora a little 

 brighter than the other segments. Wings subhyaluie, stigma rounded, 

 brown, the margins not clearly defined; a brownish mark at the 

 origin of Rs; venation : Sc endmg opposite the origin of Rs. 



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 

 with scattered hairs and a dense short pubescence. 



Habitat. — Java. 



Holotype. — Tjibodas, Mount Gede, Java; altitude, 8,000 feet 

 (Bryant and Pahner).
