NO. 2219. A REVISION OF THE VREMAISTINI—CUSIIAIAN. 621 



CREMASTUS (CREMASTUS) FLAVICEPS, new species. 



Female. — ^Length 7 mm., antennae 4 mm., ovipositor 2 mm. Dis- 

 tinct from the first two species described above in its much shorter 

 malar space and from the last four in its inwardly ])arallel eyes. 

 Head from in front broadly oval; temples weakly rounded, strongly 

 sloping; eyes straight and parallel within and about as long a.s width 

 of face; face elevated in middle, impressed at sides, minutely sparsely 

 punctate, foveo-ocular line three-fourths as long as interfoveal lino, 

 clypeus about as long as the former, broadly, evenly rounded at 

 apex; malar space equal to basal width of mandible; lateral ocoliar, 

 postocellar, and ocell-ocular lines in proportions of 1:2:1.25, ocelli 1; 

 occipital carina weak and broadly interrupted above. Thorax stout, 

 propodeimi rather steeply sloping from near base and barely reaching 

 middle of coxae; notauli fairly strong anteriorly; mesonotum dis- 

 tinctly punctate, more sparsely in middle and more densely in posi- 

 tions of notauli; scutellum punctate, strongly convex and with 

 weak lateral carinae extending to apex; thorax laterally rather 

 wealdy, sparsely punctate except pohshed longitudinal, mesopleural 

 impression, sternauli weak, metapleura more strongly punctate; 

 propodcal carinae rather weak, areola and petiolar area not dis- 

 tinctly separated but both transvei*sely rugulose, the combined 

 areas about four times as long as wide at costulae; other areas, 

 especially basal lateral and middle pleural, punctate; legs slender, 

 hind basitarsus little more than half as long as tibia and scarcely as 

 ong as next three joints; stigma about half as wide as long, radius 

 distinctly beyond middle; second abscissa of radius straight nearly 

 to apex; second recurrent very nearly interstitial, basal vein nearly 

 straight, its inner angle with median acute; nervcllus interstitial; 

 second discoidal cell slightly less than half as long at base as at apex; 

 all veins of hind wing pale and weak, the nervcllus straight and per- 

 pendicular. Abdomen less than twice as long as head and thorax; 

 first tergite distinct!}'- longer than second, petiole cylindrical without 

 carinae or foveae, stcrnite inclosed by tergite; second tergite three 

 times as long as basal width, much wider at apex, longitudinally 

 aciculate; remaining tergitcs laterally weakly punctate; ovipositor 

 one and one-half times as long as first tergite. 



Testaceous; head, including mouth parts and scape beneath, 

 flavous with ocellar triangle black, occiput and spot above each 

 antenna brownish; rest of antennae dark brown; proscutum with a 

 longitudinal dark spot which is nearly black at its anterior and poste- 

 rior ends and pale brownish in the middle, lateral lobes of mesoscutum 

 brownish; scutellum pale testaceous, surroundc<l by blackish which 

 extends backward to form a large, subtri angular spot at base of pro- 

 podeum; pre pectus blackish; petiole and second and third tergitcs 

 blackish at base, the second nearly to apex in middle; wings hyahno.
