palpus much longer than preceding segment ; antennae much longer 

 than the body, 54-segmented in type; first flagellar segment very 

 long, a little longer than the eyes. 



Thorax rather stout, deep; prescutum very prominent; notauli 

 f oveolate posteriorly ; scutellum elongate, more than half as long as 

 propodeum; propodeum ruguloso-reticulate ; sides of pronotum 

 mostly smooth, the impression straight, weakly foveate; mesopleura 

 smooth above, confluently punctate below; metapleura faintly sha- 

 greened, subopaque ; posterior coxae delicately transversely lineolated 

 posteriorly; apical teeth of trochanters well developed, conspicuous; 

 radius arising from scarcely beyond middle of stigma; radial cell 

 extending very nearly to extreme apex of wing; submedian cell 

 weakly hairy, with a completely hairless area apically ; nervulus post- 

 furcal by nearly its own length ; mediella nearly three times as long 

 as lower abscissa of basella, the latter but little longer than the upper 

 abscissa and not distinctly as long as nervellus. 



Abdomen distinctly longer than head and thorax combined; first 

 tergite fully twice as long as broad at apex, closely finely aciculate, 

 the spiracles about as far from each other as from base of tergite; 

 second tergite slightly longer than broad, completely closely finely 

 aciculate, the lateral depressed margins narrow, the sculptured part 

 of the tergite not, or scarcely, widening from base to middle; third 

 tergite very nearly as long as broad at apex, delicately aciculate on 

 basal two-thirds; remainder of dorsum of abdomen smooth; ovi- 

 positor sheaths a little longer than the body. 



Yellow-ferruginous; antennae testaceous, blackish apically, the 

 two or three basal flagellar segments not darker than the following; 

 palpi pale yellow; legs concolorous with body; wings hyaline or 

 subhyaline, stigma brownish yellow, indistinctly paler at base ; veins 

 dark brown; propodeum and first abdominal tergite weakly tinged 

 with reddish brown. 



Male. — Essentially similar to the female; antennae of allotype 

 52-segmented, the scape somewhat swollen; flagellum brownish. 



rj^ioe.— U.S.N.M. No. 43504. 



Type locality. — Carlisle, Iowa. 



Host. — Pyrausta ainsliei Heinrich. 



Remarks. — Described from seven female and six male specimens 

 reared by G. C. Decker at the Iowa Agricultural Experiment Station, 

 June, 1926. The national collection contains, in addition to the 

 type series, 14 specimens reared from the same host at Manhattan, 

 Kans., by R. Schopp ; and one specimen collected by H, H. Smith at 

 Coleta, Ala. I have also seen four specimens in the collection of 

 the European Corn Borer Laboratory at Monroe, Mich., from Car- 

 roll County, Ind., and likewise reared from P. ainsliei.
