transversally between points just in front of the outer anteapical cells ; 

 a third smoky area covering the three inner apical cells and the 

 appendage. Veins in the light areas milky white and in the dark 

 areas dark brown. Body and legs below pale, except the distal tips 

 of the tibiae and the tarsi, which are tipped with brown, and the 

 blackish claws. 



The females are generally more strongly colored, usually with a 

 large dark spot on the rounded vertex, bisected by a pale line, and 

 a black spot on either side, the elytra and scutellum are also stronger 

 marked in this sex. 



This species occurs in Central Europe. Fieber described it from 

 a male from Austria. (Have been unable to consult Kirschbaum's 

 writings.) Edwards gives only a few localities of its occurrence on 

 the British Islands. Jensen Haarup gives a single locality in Den- 

 mark. In this country it has been taken at the following places : 

 Maspeth, L. I., N. Y., Aug. i, 1908, Oct. 10, 1916, Sept. 1, 1917; Port 

 Washington, L. I., N. Y., Sept. 15, 1908; Winfield, L. I., N. Y., July 

 17, 1909 (Chris. E. Olsen). Irvington, N. J., July 14, and other New 

 Jersey localities (Edgar L. Dickerson and H. B. Weiss). In all 

 cases where food-plant is mentioned Populus alba is given. 



I wish here to express my appreciations to Prof. Herbert Osborn, 

 Dr. E. D. Ball and Mr. E. P. Van Duzee for their kind and helpful 

 correspondence of which I availed myself in the preparation of the 

 above notes.
