NO. 1920. NEW BEES AND ICirXEUMON-FLTES—VIERECK. 625 



A series of paratopot3^pcs shows this to bo a variable species in 

 color and size, ran<j:ing paler or darker than the type and smaller; 

 structurally, however, it is quite fLxed. The paratypes from north 

 Peru a,verage somewhat larger than the type and are better devel- 

 oped, with the intumescence ending in a carina and with the false 

 suture distinctly foveolate. 



MONOGONOGASTRA, new genus. 



Proposed to cover a group of species distinguishable from Campy- 

 loneurus Szepligeti by the absence of a median area or carina on the 

 third dorsal abdominal segment. 



Type. — Bracon atripectus Ashmcad. 



PERH-ITUS EPITRICIS, new species. 



Female. — Length, 1.5 mm.; labial palpi apparently two-jointed; 

 stramineous, smooth and polished, black around the ocelli, mandibles 

 with castancous tips, flagel mostly brownish, 18-jointed, the joints 

 longer than thick; notauli rather foveolate and meeting at the hind 

 margin of the mesonotum which is somewhat brownish; venation 

 virtually as in Perilitus meUinus Provanchcr, the membrane practi- 

 cally colorless, veins and stigma brownish stramineous; legs rather 

 uniformly stramineous, except the apical joint of the tarsi which is 

 rather brownish; propodeum impressed posteriori}', poorly reticu- 

 lated; petiole well differentiated, smooth, almost parallel sided, post- 

 petiole, longitudinally striated, a little shorter than the petiole, wider 

 at apex than at base and longer than wide at apex; first segment a 

 little longer than half of the rest of the abdomen, sheaths of the ovi- 

 positor at least as long as the first segment. 



Type-locality.- — Clarksville, Tennessee. 



Type.— Cut. No. 14725, U.S.N.M. 



AUotopotype. — Differs from the type chiefly in the 21 -jointed flagel, 

 blackish front, vertex, and dorsum of apical third of abdomen, rest 

 of head, thorax, and propodeum rather castaneous. 



Thet3'peis labeled "reared May 28, 1911, the allotopotype June 0, 

 1911, and two female paratopotypes May 25, 30, 1911, from adults of 

 Epitrix paroula, S. E. Crumb." The cocoon is pure white and wooly. 



APANTELES (PROTAPANTELES) FELTI^, new species. 



Female. — Length, 2.5 mm.; related to Apanteles (Protapanteles) 

 cassianus Riley from wliich it differs in the shining face, in the wings 

 being colorless with stramineous veins between the base of wing and 

 base of stigma, and with bro^vnish tinge and brownish veins beyond, 

 in the blackish stigma, in the black toguhr, and blackish wing base; 

 in the first segment being truncate and indistinctly sculptured at 

 apex, in the second plate being nearly as wide at base as long down
