in his figure but a variation not uncommon in this genus would 

 cover this discrepancy. I believe Telamona brunneipennis 

 Buckton to be but a synonym of this species. 



10. Telamona ampelopsidis Harris. 



A common and well known form found everywhere on the 

 Virginia creeper. The males are shorter than the females and 

 usually much darker, sometimes almost black, but even in these 

 dark examples the sidss of the pronotum below the crest are 

 paler, showing the outline of the brown vitta characteristic of 

 the female. It was redescribed by Fairmaire as Thelia cyrtops. 



n. Telamona coryli Fitch. 



This species is very close to ampelopsidis but it is propor- 

 tionately shorter. It has the square crest of that species but 

 the whole pronotum is more or less fuscous irregularly mottled 

 with paler which at times may cover nearly its entire surface; 

 but in all cases the anterior margin of the crest is distinctly fus- 

 cous or brown and on its posterior one half is a broad brown 

 vitta which is dislocated on its base and then runs straight to 

 the lateral margins; either side of this band the surface is paler 

 and the apex is brown or fuscous. The apex of the elytra is 

 marked with a dark fuscous spot which covers the terminal 

 areole and invades both those adjoining it. In ampelopsidis 

 there is a broad fuscous brown vitta running obliquely forward 

 from the middle of the lateral margins and covering the entire 

 dorsal crest except a central spot superiorly ; the pale line bor- 

 dering the inferior margin of this vitta follows the base of the 

 crest across the metopidium and is sharply sinuated at either 

 anterior angle. The fuscous spot on the apex of the elytra is 

 narrower and outwardly does not quite cover the terminal 

 areole. In coryli the clypeus is shorter and less distinct and 

 the surface of the face is more deeply and transversely im- 

 pressed across the base of the clypeus than in ampelopsidis 

 where it is distinguished by the usual incised angled line. 



The male of this species is almost entirely fuscous and here- 

 tofore has been identified with tristis Fitch but I have in my 

 collection a female taken near Quinze Lake, Quebec, by Mr. 

 W. J. Palmer and have seen another taken at Westfield, N. J., 

 by Mr. W. T. Davis that are darkened to an almost uniform
