Fulvous bruwn, resembling maculipennis, but with a broad yellow 

 stripe on the clavus. Length, ? 5.3 mm.; cJ*, 5 mm.; width, 1.7 mm. 



Face as in maculipennis in both sexes, pronotum lacking the black 

 spots and the light margin, the two outer spots smaller, the middle 

 one elongate; scutellum entirely rufus, darker in the male. Elytra 

 fulvous brown, the nervures indistinct, scutellar margin black ; just 

 outside this to the inargin of the clavus and extending back to just 

 before the apex of the outer claval nervure where it rounds off is a 

 distinct bright yellow area ; costal margin with a hyaline spot before 

 the tip. 



Structurally very close to maculipennis, slightly smaller, readily dis- 

 tinguished by the bright yellow clavus. 



Occurs, with the preceding, on the different species of Crafcegus. 

 Specimens are at hand from Canada, New York, Iowa, Colorado, and 

 Van Couvers Island, B. C. Mr. Van Duzee has furnished records* of 

 its occurrence at Montreal, Winnipeg, and Hamilton (Jas. Johnson), 

 Mt. Washington (Mrs. Slosson).
