and all of the flagellum beneath, all yellowish. Two large spots on 
scutellum, line on metanotum, and large spots at postero-lateral angles of 
propodeum, all yellowish. Band on tergite five reduced to medial and

Type, a male collected at Bridgeport, Nebraska, July 11, 1917 
(C. E. Mickel). Allotype, a female collected at Bridgeport, Ne-

one female paratype collected at Bridgeport, July 11, 1917 (C. E.

Related to nanus, but differs from that species in the smaller 
size, the second submarginal cell not petiolate, the distance be-

teriorly on the median line, large spot covering the sides of propodeum 
entirely (except a deep emarginate area near the spiracles) and extending 
onto the posterior face, large spot almost entirely covering the metapleura 
and with a linear extension running to the posterior coxae, large spot on
