length of the abdomen. Ferruginous; antennae blackish; except 

 the scape, which is concolorous with face; propodeum black; wings 

 hyaline or subhyaline, stigma pale brown; legs ferruginous, posterior 

 coxae on apical third, apical segment of posterior trochanters beneath, 

 and apex of posterior femora and tibiae, black or blackish; all tarsi 

 more or less infuscated; first tergite black, ferruginous at base; 

 second tergite more or less ferruginous; remainder black. 



Male. — ^Agrees in every way with the female; antennae are 30- 

 segmented as in the type. 



Type.— Cat. No. 24969, U. S. N. M. 



Type locality. — Hell Canyon, New Mexico. 



Described from six female and two male specimens reared by C. 

 Heinrich, October 17, 1916, from a larva of Acronycta, species, in the 

 Bureau of Entomology, under Hopkins, U. S. No. 13965] 1. Besides 

 the type material the United States National Museum contains a 

 large series labeled '^Pinus ponderosa; pars, on Euschausia, species, 

 Ariz.," and two other specimens, with no labels whatever, that have 

 cocoons pinned with them; these cocoons are very dark brown, 

 almost black, with a little loose grayish silk. In the collection of 

 Doctor Brues, of Harvard University, I have seen nine additional 

 specimens of this species, from Flagstaff, Arizona. The number of 

 segments in the female antennae, varies from 29 to 30; in the male 

 antennae, from 29 to 31. The blackish markings vary somewhat, 

 but apparently are more constant than usual in the species of this 

 genus.

Type. — Those of versicolor and bimaculatus are probably in the 

 Brussels Academy of Science; that of decoloratus in some German 

 museum. 



Very similar to hypJiantriae, but differs in possessing shorter 

 antennae, which are normally 27 to 30 segmented; and in the re- 

 current vein always raching cubitus decidedly before the first inter- 

 cubitus. The propleura are usually somewhat more regulose; the 

 propectus is impunctate and polished; and the propodeum is usually 

 more evenly rugulose than in hypJiantriae, with a petiolarea rarely
