carina posteriorly; mesopleura smooth and polished; anterior wing 

 with the second abscissa of radius more than twice as long as the first 

 and almost as long as the third, which goes nearly to extreme apex of 

 wing ; second segment of posterior tarsi longer than the fourth ; abdo- 

 men rather broad, mostly polished; first and second tergites weakly 

 roughened; ovipositor sheaths just about as long as the abdomen. 

 Ferruginous; head, including face, black with narrow rufous inner 

 orbital lines; thorax ferruginous except the propectus and mesopec- 

 tus, which are black; wings blackish; fore and middle legs entirely, 

 and the posterior legs, except their femora on the basal half or two- 

 thirds and the basal half of their tibiae, which parts are yellowish, 

 black; abdomen entirely ferruginous. 



Male. — Exactly as in the female except that antennse are 35-seg- 

 mented and the posterior femora are black only at apex. 



Type.—C2it. No. 28071, U.S.N.M. 



Type-locality. — San Angelo, Tex. 



AUotype-locality. — Liberty, Tex. 



Host. — Isophrictis, species. 



Described from 1 female and 1 male reared by L. J. Bottimer, from 

 larvae of the above host, the type being obtained May 27, 1924, from 

 a larva in the flower of Helmnthus and the allotype May 13, 1924, 

 from a larva in the flower-head of Rudheckia hirta. 



Subfamily Meteorinae 



METEORUS TETRALOPHAE. new species 



Very similar in general appearance and in many details to in- 

 dagator (Riley), but differs from that species particularly in having 

 the ventral margins of the first tergite joined from almost the ex- 

 treme base of the segment to a point near its middle, and in lacking 

 the large conspicuous dorsal fossae on the petiole. 



Female. — Length, 4 mm. Head transverse; temples rather flat, 

 strongly sloping; eyes exceptionally large, converging below, hairy; 

 malar space so short as to be practically wanting; face exceedingly 

 narrow, apparently even slightly narrower than in indagator., the 

 distance from the antennal foramina to clypeus being about one 

 and one-half times as long as the width of face at base of clypeus; 

 face and clypeus weakly rugulose; ocell-ocular line slightly greater 

 than the diameter of an ocellus; antennae of type broken, but a fe- 

 male paratype has the antennae 30-segmented ; mesoscutum mostly 

 smooth and shining, but with a largely strongly rugulose area be- 

 hind the middle lobe; scutellum short, broad, moderately convex; 

 propodeum only slightly hollowed out behind, and completely 

 strongly rugulose ; propleura finely rugulose and opaque ; mesopleura 

 rugulose below and in the upper anterior angles; entire thorax cov-
