that species, except that on the head the fontanelle is much larger, 

 broader, and situated higher up, being nearly as close to the vertex as 

 to the front margin of the head; the ocelli are a little nearer to the 

 eyes than in arizonensis; the mandibles are perhaps larger, or at

 brown, the rest of the body and legs yellowish; the wings are gray, 

 about as in arizonensis.
