 lateral tooth some distance from apex which is directed laterad.

Type, male and allotype, Elizabeth, 111., July 8, 1917. Paratxpe, male,

This species closely resembles qiierci Fitch, but the spots on the elytra are 

 larger and less clearly defined than in typical qiierci, the male hypopygium of 

 the latter lacks the lateral tooth, and the apex of the sheath of the ovipositor 

 in the fem.ale of qaerci is deep black.
