Digressa is closely related to apicalata^ sophrona^ errdbunda^ snowo- 

 ruTTi, and obscura. Superficially it has much the appearance of apl- 

 calata. It differs from the latter in the small, punctate, lateral proc- 

 esses of the scutellum, the first segment of the flagellum distinctly 

 shorter than the second and in the color of the pubescence of the 

 abdomen. The genitalia are similar to those of obscura and are 

 therefore not figured.
