pleurum, narrow anteroventral margin and hind corner of pronotum, 

 tegula, subtegular ridge, usually a spot on mesopleurum next to base 

 of middle coxa, mesepimeron, sometimes a narrow stripe on meso- 

 sternum next to sternaulus, large elliptical spot in upper hind part of 

 metapleurum, usually the apex and sides of median lobe of meso- 

 scutum, lateral edge and rarely mesal edge of lateral lobe of meso- 

 scutum, scutellum, postscutellum and adjacent part of metanotum, 

 and apical 0.35 ± of propodeum, pale yellow; front and middle legs 

 pale yellow, in the female the coxae partly black basally and the 

 femora partly pale brown behind; hind coxa black, in the male pale 

 yellow below, its apex narrowly pale yellow; hind trochanters and 

 hind tarsus pale yellow; narrow apex and obscure subbasal ring on 

 hind femur pale yellow, the hind femur of male more or less pale 

 yellow below; hind tibia of male pale yellow basally, below, and at 

 apex, the rest somewhat infuscate; hind tibia of female pale yellow 

 basally, the rest yellowish fulvous, brownish toward apex, but at the 

 extreme apex fulvous; first tergite often more or less pale yellow 

 basally ; first four through six tergites of male with a broad pale yellow 

 apical band; first two tergites of female with a broad pale yellow 

 subapical band which does not reach the lateral margin; third through 

 fifth tergites of female with variously developed or interrupted, narrow 

 subapical pale yellow bands; ventral part of fourth through seventh 

 tergites and under side of abdomen pale yellow; female subgenital 

 plate pale yellow with a subventral brown stripe that is strongest

The specimens from Michigan and Minnesota have the punctures 

 on the metapleurum denser (separated by about 0.5 their diameter) 

 and the yellow markings a little less extensive than in specimens from 

 farther east. They may represent a distinguishable subspecies.
