(ATELEUTI) ERIPTERNUS ELONGATUS (Davis). 

 EXERISTES NUBILIPENNIS, new species. 



Female.-— Length, 9.5 mm.; agrees with Exeristes Jiyalinipennis 

 Viereck, from which it may be separated by the darker wings, the 

 nervellus which is broken above the middle, and the smooth, highly 

 polished lateral aspects of the pronotum. 



Type locality. — Columbia Falls, Montana. 



Type.— Cut. No. 14741, U.S.N.M. 



Labeled in the same way as Exeristes Jiyalinipennis Viereck. 



EXERISTES HYALINIPENN-IS, new species. 



Female. — Length, 9 mm.; of the European species of Exeristes 

 and allied genera or subgenera this apparently agrees best with 

 Exeristes rohorator Fabricius, from the typical form of which it may 

 be distinguished by the smooth, poorly punctured head, thorax 

 and propodeum; by the nervellus being broken below the middle; 

 by the reddish and blackish hind femora; by the blacldsh hind 

 tibiae with strainineous base; by the blackish hind tarsi with the 

 base of the first segment or metatarsus stramineous; by the black 

 vaguely punctured abdomen and by the fii'st, dorsal segment being 

 apparently longer down the middle than wide at apex. 



Type-locality. — Columbia Falls, Montana. 



Type.—Ctit. No. 14742, U.S.N.M. 



Labeled, "No. 8582 Hopk.U. S., from Pissodes species, May 10-15, 

 1911, Josef Brumier collector." 



This species may prove to be only a mutant of Exeristes nubilipennis 



Viereck. 



FIEBRIGIA, new genus. 



Head lenticular; temples along the upper fourth of the eye, ^as 

 seen in profile, not extending beyond the hind edge of the eye; 

 mesopleurse with a distinct concavity extending obliquely from the 

 anterior, superior edge backward and downward. Related to 

 ZacJiarops Viereck and AmorpJiota (Foerster) Howard. 



Type. — Campoplex texanus Ashmead. 



CAMPOPLEX (HYPOTHEREUTES) EXIGUAE, new species. 



Female. — Length, 5.5 mm.; related to Hypotliereutes geometrse Ash- 

 mead, from which it may be distinguished as follows: Malar Une 

 nearly as long as mandibles are wide at base; scape and pedicel 

 blackish; fore and mid coxas brownish; femora reddish bro-\vn; fore 

 and mid tarsi brownish stramineous, liind tarsi dark brown, only the 

 basal joint pale at base, hind, proximal trochanter blacldsh; areola 

 wider than long; the areopetiolarea similar in outline to the same in 

 Hyposoter parorgyise Viereck, planate, at least not appreciably con-
