Falls Church, Virginia. Described from two females, one (type) 

 recorded under Bureau of Entomology No. Ilopk. U. S. 11325c and 

 from two males (one, allotype) recorded under Bureau of Entomology 

 No. Hopk. U. S. 10175c. These numbers refer to notes stating that 

 this species is a primary parasite on Difrion lecontei, material col- 

 lected and reared by William Middleton and S. A. Rohwer. 



Type.— Ceit. No. 18521, U.S.N.M. 



LAGAROTIS VIRGINIANUS, new species. 



This species is very like Lagarotis diprioni but may be separated 

 from that species by having the propodeum and most of the mesepi- 

 sternum black, and by having the abdomen black except whitish 

 bands on the third and fourth tergites. 



Falls Church, Virginia. Described from one male recorded under

Genus HOMALOMMA Forster. 



This Foersterian segregate has as yet had no species placed in it. 

 The following three species seem to agree with Foerster's and subse- 

 quent writers' conception of Foerster's genus. 



The roughened cheeks, the lack of a depression separatmg the 

 clypeus from the face readily separate this genus from most of the 

 others. From Habrodactylis it is separated by the shorter apical 

 joints on the hind tarsi and by the completely areolated propodeum. 



Type. — Homalomma caliroae, new species. 



The following table will differentiate the three species here con- 

 sidered : 



Black, with white markinge pteronideae. 



Femiginoua 1 



1. Apical middle of the eecond tergite smooth, impimctate eriocampoides. 



Apical middle of the second tergite sculptured like the rest of the segment. m?i>oae. 



HOMALOMMA CALIROAE, new species. 



Female. — Length 4.5 mm. Apical margui of the clypseus slightly 

 depressed, the surface shining, almost impunctate; the entire head 

 opaque with fine granulations, median tubercle much reduced; 

 ocellocular luie subequal with the postocellar line; postocellar area 

 parted by a faint furrow; third and fourth antennal joints subequal; 

 mesoscutum opaque, laterally with a few large, separate punctures; 

 scutellum sculptured similar to the scutiun but the punctures smaller 

 and sparser; propodeum completely areolated; basal area but little 

 wider anteriorly than posteriorly, hexagonal in outline; the anterior 

 lateral legs subequal in length with the anterior face, and but about
