Kellogg describes this subspecies as follows: 



Differs from the types of fissus by having a hair in 

 the eye, by having 4 pustulated hairs on each lateral 

 half of the posterior margin of the metathorax instead 

 of 3, 2 being median and 2 being near the angle; by 

 having the median longitudinal uncolored line of the 

 abdomen limited to the first 2 segments, and by being 

 markedly larger.
