- THE CANADIAN ENTOMOLOGIST 409 



above the ventral ends of the eyes, 13-jointed with two ring-joints, 

 the club normal, the pedicel subequal to funicle 1, twice longer 

 than wide at apex. Genal suture distinct. Clypeus sinuate, at 

 the meson with a distinct, sharp tooth; clypeus subglabrous, 

 nonstriate. Caudal tibial spurs distinct, double. Venation as 

 in Pteromaliis but the marginal vein is thickened a little at base. 

 Mandibles 3- and 4-dentate. Otherwise as in Habrocytus rhodobani 

 Ashmead, but the median carina of the propodeum is absent (the 

 lateral distinct), and the spiracular sulcus is only somewhat indi- 

 cated by a hollow (no true sulcus). Has nothing to do with 

 Homoporus or Phanacra, and is a miscogasterid of the present 

 Metastenini. 



THE OCCURRENCE OF NEODEROSTENUS GIRAULT IN 

 NORTH AMERICA (HYMENOPTERA). 



BY A. A. GIRAULT, GLENNDALE, MD. 



A species from the woods, June 4, 1916. The abdominal 

 petiole in this American species is transverse-linear. 



Neoderostenus bipunctatus, new species. 



Female. — Length 0.95 mm. 



Brassy metallic green, the wings hyaline, the venation dark, 

 the legs and scape (except the middle and caudal coxae except at 

 extreme apex), white. Head and thorax densely scaly, the scutum 

 scaly-punctate, the scutellum with a compound, 3-foveate puncture 

 at middle between meson and lateral margin (and sometimes with 

 another puncture caudo-mesad of the fir t), somewhat as in the 

 Australian Achrysocharoides sarcophagus Girault. Parapsidal fur- 

 rows at cephalic sixth mere sutures, thence subglabrous, rather 

 broad grooves. Propodeal spiracle minute, round, cephalad (but 

 over its own diameter from the cephalic margin). Propodeum 

 subglabrous. Postmarginal vein no longer than the short stigmal, 

 the marginal fringes of the fore wing very short. Funicle joints 

 subequal, each about twice longer than wide, a third longer than 

 the pedicel which is a little longer than club 1 ; terminal spine of 

 club distinct. Mandibles 5-dentate, the two outer teeth large, 

 subequal, the inner three subequal, minute. 



One female by sweeping, Glenndale, Maryland.
