 paratype male, Thomasville, Alabama, W. D. Pierce collector. 



ROGAS RUFOCOXALIS, new species. 



Ferfmle. — Length 5.6 mm. Head transverse, the posterior orbits 

 about as broad as two-thirds the eye-width; sparsely punctate and 

 polished ; vertex transversely rugose ; ocelli rather large, in an equi- 

 lateral triangle, the postocellar line less than the ocellocular; frons 

 less strongly wrinkled than the vertex; face transversely rugulose 

 above with a strong median ridge ; cheeks punctured and shining like 

 the posterior orbits ; malar space distinctly longer than the width of a 

 mandible at base ; opening between clypeus and mandibles moderately 

 large and nearly circular; eyes distinctly though not deeply emargi- 

 nate ; antennae longer than the body, 47-jointed in the type, the first 

 flagellar joint about twice as long as broad or a little longer, following 

 joints slightly shorter; mesoscutum and scutellum shining with weak 

 punctures, the parapsidal grooves terminating posteriorly in a rugu- 

 lose area; propodeum rugose with a distinct median carina; tarsal 

 claws distinctly pectinate; first abscissa of radius shorter than the 

 second which is about equal to the first intercubitus, second intercu- 

 bitus equal to the first or nearly, the second cubital cell subquadrate ; 

 nervulus far behind the basal vein, the first and second abscissae of 

 discoideus equal or nearly so ; abdomen a little longer than the thorax, 

 the first, second, and basal half of the third tergites strongly rugoso- 

 striate with a distinct median carina on the first and second ; apex of 

 third and all of the following tergites polished. Head, antennae in- 

 cluding scape, palpi, and all legs except their coxae black; thorax, 

 abdomen, and all coxae ruf o-testaceous ; wings hyaline, the costal vein 

 and stigma black, other venation dark brown. 



Male. — Similar in every respect to the female except that the apical 

 segments of the abdomen are blackish and closely covered with white 

 hairs. 



Type-locality. — Eocky Ford, Colorado. 



Type.—C2ii. No. 20385, U.S.N.M. 



Hosts — Autographa brassicae and Peridroma margaritosa. 



Type, allotype, and four paratypes reared by H. O. Marsh from 

 larvae of Autographa brassicae and recorded in the Bureau of Ento- 

 mology under Chittenden No. 1088 ; also two males and one female 

 from Tempe, Arizona, reared by L. J. Hogg, from larvae of Peridroma 

 margaritosa and recorded under Webster No. 11978. 



This species is apparently exactly like the type of molestus Cresson 

 except that the mesosternum, mesopleura, and propodeum of molestus 

 are black. It would not be surprising if it would ultimately turn out. 

 to be merely a color variety of Cresson's species.
