slightly exceeded by the ovipositor; male valve roundingly pointed, 

 plates broad and short; antennae with small, slightly elongate discs. 

 Occurs on willows. Specimens are at hand from Iowa, Nebraska 

 and Colorado. The short, broad form and cinnamon color will read- 

 ily separate this species from any other.

Large, pale, yellowish, washed with brown, a large spot against 

 either eye and a line between the two spots on the vertex, dark brown. 

 Length, 9 7 mm.; c?, 5.5 mm.; width, 9 2 mm.; c?, 1.5 mm. 



Face yellow, usually a large triangular spot against either eye, a 

 smaller one on the front just within and below either ocellus and a 

 band between the two spots on vertex, dark brown. Pronotum pale 

 yellowish, milky posteriorly, more or less marked with darker. Elytra 

 milky white, the nervures distinct, dark brown, outer anteapical cell 

 very variable in size, often wanting. Ultimate ventral segment of the 

 female strongly medially produced ; male antennal discs large, twice 

 longer than wide. 



Mr. Van Duzee notes it from Franconia and Mt. Washington, N. H. 

 (Mrs. Slosson), Mountains of Northwestern Colorado (Gillette.) 



Specimens are at hand from Ontario, New York, and Colorado. 

 This is a very variable species both in size and coloration and has 

 been confused with several other species. When the spots on the face 

 are present they will readily separate it from any other species ; when 

 wanting, as is often the case in the male, the short or wanting anteap- 

 ical cell, the produced female segment, and the long nearly parallel- 

 sided disc of the male antennae will serve to readily separate it. 



The /. productus of G. & B., on examination of a type, ])roved to be 

 founded on nothing but a pair of crushed specimens of the above 

 species, the " remarkable form of the head " being due to the vertex 

 having been pushed forward and crushed along a middle line — prob- 

 ably when the specimens were very fresh, as the coloring matter had 

 somewhat segregated into the crushed area, but not forming a distinctly 

 bounded black sj)Ot as shown in the cut accompanying the description.
