 twice as long as thick; end joint a little more than twice as long as thick; 

 flagel dullish, almost straight in outline; antennae blackish throughout;

 more puncture-widths apart, mostly the latter; notauli represented by a 

 shining line; mesopleurae dullish with pale-ochreous hairs throughout, finely 

 reticulated and mostly covered with shallow pits, that are mostly three or 

 more pit-widths apart; scutel with longer hair and sparser sculpture than 

 the dorsulum ; metanotum hairy Hke the scutel, more densely sculptured than 

 the dorsulum; tegulae dark brown, polished; wing-base mostly pale stramin- 

 eous, subcosta blackish, stigma and other veins pale stramineous, membrane 

 uniformly tinged with brown; legs blackish excepting the tarsi which are 

 rather dark brown, legs covered with ochreous hairs; hind metatarsi at most 

 hardly wider than mid-metatarsi and nearly half as wide as hind tibiae at 

 apex of the latter ; propodeum with its enclosure poorly defined, with irregular 

 weak rugae at basal edge, finely reticulated elsewhere, rounded off at apex, 

 rest of upper face sculptured somewhat like the mesopleurae but dulUsh 

 and with closer pits and covered with ochreous hair; propodeal pleurae 

 sculptured apparently hke the remainder of the propodeum outside of the 

 enclosure; abdomen with its tergum shining, almost polished, finely reticu- 

 lated and indistinctly punctured, the punctures mostly four or more puncture- 

 widths apart ; first tergite with erect pale-ochreous hairs, second and following 

 tergites with appressed sparsely distributed ochreous hairs; second tergite 

 with its elevated portion down the middle : depressed portion : : 17 : 6; 

 fifth tergite with its basal blackish portion covered with poorly defined 

 punctures that are as many as four or more puncture-widths apart, rest of 

 fifth tergite and exposed portion of sixth and seventh tergites with a stramine-

 tergum with rather inconspicuous hairs that are not supplemented by con- 

 spicuous hair-bands; hair at apex of abdomen of a golden hue; cardo finely

In a male paratype from Mt. Washington, New Hampshire, 

 Tuckerman's Ravine, July 8, 1914 (C. W. Johnson), the cheeks 

 are simpler so that the production found in the type is barely 

 outlined; otherwise this paratype seems to agree throughout with 

 the type.
