LeConte described fissilabris from Lake Superior and 
Hudson’s Bay Territory and since the time of its descrip- 
tion very few specimens have been taken. These, how- 
ever, show that there is a close relationship between it and 
cinerea. The author was unable to distinguish between 
the two species at the time he wrote his revision of the 
genus, except on the basis of color. Subsequent speci- 
mens indicate from their distribution that fissilabris is a 
marginal form of cinerea. It has been taken at Aweme, 
Manitoba; Tokio, North Dakota; Hope, Arkansas and 
Smithville and Stillwater, Oklahoma. These localities 
coincide fairly well with the northern and western limits 
of cinerea. The Arkansas and Oklahoma specimens were 
taken in company with normal cinerea.

It is hoped that at last our common margined blister 
beetle has a name that will stick with it. 
Epicauta ficta sp. n. 
This unicolorous grey species is most closely allied in 
our fauna to cinerea (Forst.), having similar antennse but 
broad posterior tibial spurs. It differs from grey speci- 
mens of pestifera in its short, stout antennse and from 
brunnea Werner by the broad posterior tibial spurs and 
unexpanded anterior tarsi in the male. It seems to be 
most closely related to Epicauta obesa from Vera Cruz on 
the Caribbean coast of Mexico. 
Length: 9 to 12 mm. Black, densely clothed with de- 
cumbent cinereous to yellowish-cinereous pubescence. 
Antennse short but of a form similar to those of cinerea. 
Head subtriangular. Surface microreticulate, densely 
ard rather deeply punctured. Midline very feebly im- 
pressed, usually not visible under low magnification. 
Antennal calluses small, slightly raised, denuded and
