No.2301. DESCRIPTIONS OF NEW SAWFLIES—ROHWER. 107 



Subfamily Phymatocerinae. 



TOMOSTETHUS (TOMOSTETHUS) TENUICORNIS, new species. 



In the rather long, slender antennae this species differs from the 

 other members of the genus. In color it is much like liirticornis 

 Rohwer, but the legs are darker than they are in that species. 



Female. — Length, 6.5 mm.; length of antennae, 4.75 mm. Cly- 

 peus long, the anterior margin very slightly emarginate, the lateral 

 angles rounded; supraclypeal area triangular in outline, gently con- 

 vex: middle fovea large, deep, nearly circular in outline, open below; 

 antennal foveae deep, extending dorsally to a little above the level 

 of the middle fovea; antennal furrows and pentagonal area obsolete; 

 a line-like depressed area in front of anterior ocellus; postocellar 

 line but little more than half as long as the ocellocular line; posto- 

 cellar furrow poorly defined; vertical furrows deep, straight, com- 

 plete; postocellar area one and one-third times as wide as long; 

 antenna slender, slightly tapering apically, covered with short hair, 

 the third joint only slightly longer than the fourth; stigma rounded 

 below, truncate apically; third cubital cell very short, its length on 

 cubitus subequal, on radius shorter than the third intercubitus ; 

 interradius curved, joining radius somewhat beyond middle; claws 

 with an inner tooth near base; sheath concave above, convex below, 

 rounded apically. Black; pronotum, mesonotum (except scutellar 

 appendage), and upper part of mesepisternum rufous; tibiae dark 

 piceous; wings hyaline, with a faint dusky tinge; venation dark 

 brown. 



Type locality. — Murree, 7,500 feet (about 2,272 meters), British 

 India. 



Described from a single female collected June, 1918, by Dutt and 

 orwarded by the Imperial Entomologist of India. 



Type.— Cat. No. 22542, U.S.N.M. 



TOMOSTETHUS (TOMOSTETHUS) GRACILICORNIS, new species. 



In general appearance more like Tomostethus (Eutomostethus) assa- 

 mensis Rohwer, but the antennae are more slender and the femora 

 yellow. 



Female. — Length, 6 mm.; length of antenna, 3 mm. Anterior 

 margin of clypeus truncate, the lateral angles rounded; supraclypeal 

 area rectangular in outline, only gently convex; median fovea large, 

 deep, rectangular; antennal foveae deep, extending well above the 

 top of the median fovea; pentagonal area triangular in outline, 

 enclosing the anterior ocellus, lateral walls rounded, ventral wall 

 poorly defined; antennal furrows well defined; postocellar furrow 

 poorly defined; vertical furrows deep, well defined, slightly curved; 

 postocellar line one-fourth shorter than the ocellocular line: antenna 

 slender, clothed with long hair, joints not well separated, third joint
