The type of this species has not been seen by the writer, his con- 

 ception of the species being based upon a specimen in the National 

 collection determined by A. B. Gahan after an examination of the 

 type. This specimen was collected at Agricultural College, Michi- 

 gan. In addition, the National Collection contains a female speci- 

 men taken at Cailinville, Illinois, by Charles Robertson; also an- 

 other female reared by H. L. Parker at Hagerstown, Maryland, 

 September 10, 1916. The writer has also seen three female speci- 

 mens, taken at Ames, Iowa, which are in the collection of the Iowa 

 Agricultural Experiment Station.

 polished ; propodeum rugoso-punctate, with a distinct roughly circu- 

 lar areola; apical angles projecting strongly posteriorly; forewing 

 with the metacarpus longer than the stigma, and the radius much 

 longer than the transverse cubitus; posterior coxae shining; inner 

 spur of posterior tibiae not quite half the length of the metatarsus ; 

 abdomen large and stout, at least as long as the thorax ; first tergite 

 broad at base, narrowing somewhat toward apex, finely ruguloso- 

 striate, and with an indistinct median longitudinal depression on 

 apical half ; second tergite transverse, very short, but longer medi-
