one-fourth longer than the fourth; stigma tapering from near base; 

 third cubital longer on both radius and cubitus than the first and 

 second combined; interradius curved, received at apical third; ner- 

 vulus somewhat less than its length from end of cell; claws with a 

 large erect inner tooth a little beyond middle; sheath slightly con- 

 cave above, strongly convex beneath, rounded apically. Black, 

 shining; legs below apices of coxae yellow; apical tarsal joint slightly 

 infuscate; wings hyaline; venation black. 



Male. — Length, 5 mm. Agrees in color and structure with female. 



Type locality. — Shillong, British India. 



Described from one female (type) and seven (one allotype) males 

 collected June and July, 1918, by T. B. Fletcher at an altitude 

 of 5,000 feet (about 1,515 meters). Forwarded by the Imperial 

 Entomologist of India. 



Type, allotype, and paratypes. — Cat. No. 22543, U.S.N.M. 



Paratypes (males) returned to imperial entomologist of India. 



Subfamily Nematinae. 



HEMICHROA (HEMICHROA) ORIENTALIS, new species. 



This species is closely allied to the European H. crocea (Geoffroy), 

 but may be distinguished by the black hind legs and the shape of the 

 sheath. H. major Rohwer the only other oriental species belonging 

 to this genus is quite different. 



Female. — Length, 7 mm. ; length of antenna about 5 mm. Ante- 

 rior margin of the clypeus with a deep U-shaped emargination, the 

 lobes broad and rounded apically; supraclypeal foveae deep elongate, 

 confluent with antennal foveae; supraclypeal area broadly triangular 

 in outline, gently convex; middle fovea elongate rather well defined, 

 breaking through the crest; ventrad of middle fovea is a small rounded 

 tubercule; ocellar basin hexagonal in outline, rather well defined, 

 especially so dorsally; a small nearly circular fovea below anterior 

 ocellus; inter-antennal area parted by a deep furrow; postocellar line 

 a trifle shorter than the ocellocular line; postocellar furrow present 

 but not sharply defined; vertical furrows well defined, diverging 

 posteriorly; anterior width of postocellar area not quite twice its 

 median length; antenna tapering, the third and fourth joints sub- 

 equal; stigma broadest at base gradually tapering to apex; interradius 

 curved, received at about middle of cell; recurrentella about the 

 length of intercubitella before intercubitella; sheath broad, straight 

 above narrowly truncate at apex, tapering to broad base. Rufo- 

 ferruginous; antennae, trophi, proepisternum ; mesosternum, meta- 

 pleurae, metascutellum, sheath and legs (except the apices of ante- 

 rior femora and the tibiae beneath) black; wings brownish, clearer
