4. Unknown. 
Type, Glen, Sioux county, Nebraska, altitude 4,000 ft., August 
15, 1906 (P. R. Jones) ; one paratype, same label as above. 
The paratype differs from the type in being slightly smaller, 
in having the postscutellum yellow, the first abdominal segment 
entirely reddish with a subinterrupted yellow band, and the sec- 
ond segment reddish basally; these two segments are also red- 
dish ventrally. Allied to nigrescens, from which it is very distinct.
