 State Ent. Bull., 17, p. 88, (1916). 



Size and general appearance of balli, vertex slightly shorter 

 and genitalia distinct. Length 6-6.5 mm. 



Vertex bluntly angulate, one-half broader than long, one- third 

 longer on the middle than next the eye, margin thick.

 three-fourths the way to base, the apical half of the excavation
