joints quadrate, subapical joints slightly longer than thick, apical, 

 joint distinctly elongate. Humeral margin of pronotum finely punc- 

 tate, opaque; mesoscutum and scutellum shining, with rather coarse 

 distinct punctures, notauli represented by deep pits anteriorly from 

 which very faint impressions converge backward to a shallow median 

 impression; thorax laterally mostly highly polished, anterior half of 

 mesopleurum and mesosternum finely punctate; propodeum, except 

 the polished areola, finely punctate, areola not separated from basal 

 area, the combined area more than twice as long as broad at middle, 

 where the costulae are received ; hind femur hardly twice as long as 

 deep. Abdomen very finely and rather densely punctate. 



Black with cinereous pubescence, longest on face, sternum and 

 coxae; mandibles, upper margin of face, and antennae ferruginous; 

 front and middle legs reddish stramineous, middle coxae and femora 

 more or less brownish; hind coxae except apex and femur except 

 extremities black, hind leg otherwise testaceous; wings yellowish 

 hyaline especially basad of stigma, where the venation is also yellow, 

 stigma and apical venation brownish; venter pale brownish yellow; 

 sheath of ovipositor whitish. 



Type locality. — Batu Caves (Dark Cave), Selangor, Federated 

 Malay States, 800 feet from entrance. 



Type.~Q,2.i. No. 41102, U.S.N.M. 



Four females, all taken by C. Dover. 



PANISCUS PLATYPES. r.ew species 



Remarkable chiefly for its very distinctly flattened tarsi. In my 

 key to North American species ^ it runs best to paUens Cushman, but 

 is distinctly larger, the abdomen and legs stouter, and the tarsi much 

 more strongly flattened. 



F&mdle. — Length 18 mm., antennae (broken). 



Temples rather strongly convex and only a little narrower than 

 eyes; ocelli large and nearly contiguous with the eyes; face hardly 

 as long as broad, fully a half broader than frons, minutely opaquely 

 shagreened, sparsely punctate, strongly elevated medially; clypeus 

 more than half as long as interfoveal line with basal groove arched 

 above level of foveae, weakly emarginate at apex, weakly convex, 

 sculptured as face but with punctures larger and sparser ; malar space 

 short but distinct; antennae broken, flagellum apparently tapering 

 from base to apex, the twenty-second joint about twice as long as 

 thick. Thorax very finely and densely punctate opaque, the pleura 

 less densely so and shining; notauli long, shallow; scutellum mar- 

 gined to apex, the space between the carinae nearly two-thirds as 

 broad at apex as at base; metapleurum finely striato-punctate; pro-
