12 PBOCEEDINGS OF THE NATIONAL MUSEUM vol. 7&- 



beyond middle of stigma; nervellus nearly perpendicular, slightl}.'" 

 broken not far below middle; hind basitarsus hardly three-fifths as 

 long as tibia and distinctly shorter than rest of joints combined; 

 postpetiole barely thicker than petiole; second tergite two and a half 

 times as long as broad at base, sides divergent. 



Pale yellowish testaceous; occiput, vertex, and frons fuscous; orbits 

 yellow; antennae fuscous with apices of joints of basal half narrowly 

 pale; stigma largely whitish, other veins brovrn; legs somewhat in- 

 fuscate; prescutum entirely and areas between scutellum and wing 

 bases fuscous, as are also basal half of second tergite and more or less 

 of sixth and seventh. 



Mal^ — Eyes divergent below ; diameter of ocellus distinctly shorter 

 than ocell-ocular line; second tergite little more than twice as long 

 as broad at base ; color like female. 



CREMASTUS RHYACIONIAE, new species 



Very similar to epagoges Cushman, to which species the female 

 runs in my key to North American species. Because of its large 

 eyes and ocelli the male runs to forhesii Weed. 



Female. — 6-7.5 mm. (type 7 mm.). 



Differs from epagoges female principally as follows: Face dis- 

 tinctly narrower than height of eye ; malar space shorter than basal 

 width of mandible ; pronotum laterally polished, ver}'^ weakly f oveo- 

 late at bottom of impression (in epagoges the pronotum is shagreened 

 laterally and strongl}?^ foveolate in impression) ; mesoscutum more 

 finely and sparsely punctate, notauli weaker; ovipositor sheath a 

 little more than twice as long as first tergite. 



Face black medially; orbits uninterrupted yellow but much nar- 

 rower than in epagoges^ especiall}'- at top of eye; thorax entirely 

 black except humeral angle of pronotum which is brownish and 

 basal part of scutellar carinae which is whitish (sometimes the 

 scutellum is more or less reddish brown) ; stigma broadly pale along 

 anterior margin. 



Male. — Differs from epagoges male as follows : Eyes much longer 

 than width of face ; malar space hardly half as long as basal width of 

 mandible; diameter of ocelli more than half as long as postocellar 

 line and nearly twice ocell-ocular line. 



Host. — Rhyacionia frustrana var. hushnelli Busck. 



Type locality. — Pactola, S. Dak. 



Type.— Cat. No. 41997, U.S.N.M. 



Seven females and two males reared by L, G. Baumhofer from 

 the host in Pinus ponderosa under Hopkins U. S. No. 17511.
