numbers on willows at Wallace, Kansas, on the Smoky Hill River in 

 western Kansas during July. One specimen was beaten from willow 

 in Comanche County, southwestern Kansas." 



The dates on specimens examined were: Kansas, July i, 2, 3; Iowa, 

 July 28; Illinois, August 3 (specimen not typical) ; Awame, Manitoba, 

 July 7; Virginia, June 27. The other specimens bore no date of 

 capture. 



The general distribution seems to be from Manitoba and Lake 

 Michigan, south to the Gulf of Mexico and westward to the extreme 

 western boundary of Kansas. 



Poecilonota cyanipes Say. Plate VI, figs. 13 and 14 and Plate VII, figs. 6 

 and S. 



The original description as set down by Say^ is : 



" B. cyanipes — Elytra at tip narrowed; entire and divaricated ; scutel 

 transverse." 



" Inhabits Missouri." 



" Body dark cupreous, tinged with greenish ; head, before the antennae, 

 green ; antennae dark green ; thorax confluently punctured ; scutel large, angu- 

 lated each side behind, and excavated in the middle ; elytra with darker 

 abbreviated, elevated irregular lines; tips very slightly recurved, divaricated, 

 entire or obsoletely truncate; beneath bright cupreous, not canaliculate, tail 

 deeply emarginate : tarsi blue." 



"Length two fifths of an inch." (10 mm.) 



" Missouri . . . resembles the divaricata in the manner of terminating 

 of the elytra." 



The examination of a considerable number of specimens has re- 

 vealed the fact that this species varies considerably ; the elytra are nar- 

 rowed, prolonged and divaricated; the extreme tips are truncate or very 

 slightly concentric, tending to be bisinuate; scutellum transverse and 

 extremely variable in form. Color varies from cupreous to coppery- 

 green to dull black and dark purple. The front may be green or cop- 

 pery without regard to the sex. Antennae green, first joint often cop- 

 pery. Thorax coarsely, confluently punctured, more so laterally, with 

 an elevated, smooth median line ; elytra sparsely punctate, prominently 

 striate, tips usually coppery ; under parts cupreous, sometimes bright, 

 sometimes dull. Fresh specimens often covered with a cotton-like sub-
