The males of this species (and of odontophora) have the fifth seg- 

 ment of the flagellum distinctly wider than any other segment in it. 

 In both species the males have the second sternite with an evident 

 process, but discisa differs from odontophora in having the anterior 

 tarsus of normal form, in having the posterior border of the middle 

 femur plain, and in having the apical segment of all tarsi entirely 

 or in part black. The fasciae on the tergites of both sexes of discisa 

 are almost white and are narrow, narrower than those on spinosa and 

 much narrower than those on variegata.

 combination or fusion of yellow and ferruginous. As distinct from 

 the black ground color the maculations are as follows : labrnm ; man-

 tween and below insertion of antennae, except median apical spot; 

 scape and first four segments of flagellum ; anterior orbits shortened
