quadrate, second intercubitus distinctly broken; second recurrent 

 interstitial, rather weakly and evenly curved thoughout; nervulus 

 postfurcal b}' about two-thirds its length; postnervulus broken at 

 upper third; nervellus broken slightly above upper third; hind femur 

 distinctly less than two-thirds as long as tibia; tarsi slender, apical 

 joint of middle tarsus about as long as third, claws small with about 

 ten large teeth. Abdomen rather slender; first tergite four times as 

 long as wide at apex, spiracle at basal third; second tergite nearly 

 twice as long as wide at base, sides moderately divergent. 



Testaceous; face andfrons medially paler; clypeus, orbits, and ver- 

 tex yellow; antennae fuscous except at base; wings hyaline, vena- 

 tion blackish, stigma and costa pale; legs concolorous, tarsi slightly 

 paler. 



Type-locality. — Ritzville, Washington. 



Type.— Cat. No. 25989, U.S.N.M. 



Two females taken May 13, 1921, by M. C. Lane. 



The paratype is slightly larger than the type with the antennae 

 more extensively testaceous at base and lacks the abnormal stubs of 

 veins on the second intercubitus and second recurrent that are present 

 in the type; but is otherwise very similar. 



PANISCUS SPINIPES, new species. 



Female. — Length 14 mm.; antennae 13 mm. 



Temples rather broad and strongly convex but not distinctly buc- 

 cate; face broader than long, sparsely punctate, medially somewhat 

 elevated, nearly a half broader than frons; clypeus short and broad, 

 convex, broadly truncate at apex; frons flat, subopaque, transversely 

 aciculate; ocelli slightly removed from eyes; antennae rather slender, 

 joints beyond middle less than twice as long as thick. Thorax shin- 

 ing; mesoscutum very finely and inconspicuously punctate, notauli 

 extending well onto disk; scutellum margined throughout, space be- 

 tween carinae broad and rather weakly convergent; mesopleurum 

 slightly more distinctly sculptured than mesoscutum; metapleurum 

 very finely punctate; propodeum rather strongly rounded from base 

 to apex, transversely striate, apophyses weak, spiracles broadly oval; 

 areolet subpetiolate, subquadrangular ; second recurrent slightly 

 postfurcal, strongly curved above, nearly straight below middle; 

 nervulus postfurcal by about two-thirds its length; postnervulus 

 broken at upper third; nervellus broken at upper third; hind femur 

 distinctly less than two-thirds as long as tibia; tarsi rather slender, 

 apical joint of middle tarsus slightly longer than third, claws small 

 with about ten large teeth; legs conspicuously spiny. Abdomen 

 moderate; first tergite not quite four times as long as wide at apex, 

 spiracles slightly beyond basal third; second tergite nearly twice as 

 long as wide at base, subparallel-.sided.
