sharply truncate, this truncation continues to the posterior ventral 

 margin, and leaves a shelflike depression to the sternum which is 

 prominent and armed with two teeth posteriorly; abdomen polished, 

 cjdindrical. longer than head and thorax; propodeal spiracle at about 

 the middle of the lateral margin; sheath straight above, obliquely 

 truncate apically, convex below; wings long and slender; interradius 

 curved at almost a right angle and joining the radius slightly beyond 

 the middle of the third cubital cell; third cubital longer on both 

 radius and cubitus than the first and second combined, receiving 

 the second recurrent a little beyond basal fourth; first recurrent at 

 about the middle of second cubital; first discoidal cell elongate, the 

 first recurrent shorter than the basal; nervulus half its length beyond 

 basal. Black; clypeus, labrum, mandibles (except apices), and 

 tegulae yellow; antennae black with fourth and following joints and 

 apical part of third beneath, f errugineous ; abdomen brownish with 

 a longitudinal median dorsal and lateral lines somewhat paler; 

 propodeum dark brown with a yellowish median spot; legs yellowish, 

 coxae black, posterior femora and tibiae rufous; wings uniformly 

 yellowish; venation black, costa and stigma f errugineous ; tibiae 

 and tarsi with short hair. 



Type locality. — Kumaon, Ramgarh, 6,000 feet (about 1,818 

 meters), British India. 



Described from one female collected August 21-26, 1918, by 

 T. B. Fletcher. 



Type.— Cut. No. 22610, U.S.N.M. 



TENTHREDO BALABATEA, new species. 



Judging from the descriptions, this species is probably more 

 closely allied to (Allantus) Tenthredo incognitus (Bingham), but it 

 may readily be distinguished from that species by the black thorax. 



Male. — Length, 9 mm.; length of antenna, 4.5 mm. Labrum 

 polished, broadly rounded apically; clypeus shining, with widely 

 separated, setigerous punctures, the anterior margin deeply sub- 

 squarely emarginate, with broad roimded lobes; head with close 

 (sometimes almost confluent) rather large punctures; middle fovea 

 elongate more or less ellipitical in outline; antennal furrows not 

 especially prominent; postocellar area well defined, rectangular 

 in outline, twice as wide as long; postocellar line sub equal with the 

 ocellocupital line but hardly half as long as the ocellocular line; 

 antennae thickening apically, the third joint as long as the fourth 

 and fifth which are subequal; mesonotum shining, with distinct, 

 rather close, well defined punctures : mesepisternum closely punctato- 

 granular, opaque; scutellum gently convex; stigma straight below; 

 obliquely truncate at base and apex; third cubital cell longer on both 

 radius and cubitus than the second; interradius received at about
