 lar sculpture. Head transverse, narrowed behind, the posterior orbits 

 hardly half as wide as the transverse diameter of the eyes; ocelli 

 small, the greatest diameter of a lateral ocellus slightly less than the 

 postocellar line which is about equal to the ocell-ocular line; eyes 

 distinctly but not deeply emarginate, malar space longer than the 

 width of a mandible at base ; opening between clypeiis and mandibles 

 not large; antennae 33-jointed in the type, all flagellar joints two or 

 more times as long as thick; parapsidal grooves present but not

 scutellum; propodeum granularly rugulose with a median longi- 

 tudinal carina ; first radial abscissa of the forewing shorter than the 

 first transverse cubitus and a little more than half the length of the 

 second radial abscissa ; second cubital cell narrowed slightly apically ; 

 submedian cell longer than the median by about one and one-half 

 times the length of the nervulus; abdomen as long as the head and 

 thorax, the first, second, and third tergites very finely rugulose, the 

 first and second with a median carina which is also traceable on the 

 third; ovipositor exserted about the length of the fourth tergite. 

 Color dark fusco-testaceous, the eyes, triangle enclosed by ocelli, 

 mesoscutum except broad parapsidal stripes, upper part of meso- 

 pleura, mesosternum, propodemn, base of first tergite, and the ovi- 

 positor sheaths blackish; antennal flagellum blackish apicallj'^, the

Type.—Qsit. No. 20382, U.S.N.M. 



Host. — Peridroma nmrgaritosa. 



Type, allotype, and four paratypes from Tempe, Arizona, reared 

 by L. J. Hogg, from the larvae of Peridroma margaritosa and re- 

 corded under Webster No. 11978 ; paratype reared by W. R, McCon- 

 nell at Roswell, New Mexico, from unknown larvae and recorded in 

 the Bureau of Entomology under Webster No. 12634; paratype, 

 Brownsville, Texas, R. A. Yickery, Webster No. 6437, reared from 

 Heliothis ohsoleta; paratype. Springer, New Mexico, C. N. Ainslie

This species is closely related to autographae Viereck, from which 

 it differs principally by having larger ocelli, more finely sculptured 



» If the conclusions of Mr. Vioreck In Bull. 83, U. S. Nat. Mus., p. 7, are correct this 

 name should be changed to Aleio'lea.
