in Alpine and northern Enrope, and many portions of Arctic and 

 eastern Siberia ; the var. ustulata Gebler is found throughout eastern 

 Siberia, and at Kanitschatka, and is the prevailing American form,

391. Leptura {Strangalia, Pachyta) sexmaculata Linn. 



This is likewise a northern species. My specimens are from Mt. 

 Washington, N. H. From there it extends northward to the Hud- 

 son's Bay region and westward to northern Michigan and the Lake 

 Superior region. Vexatrix Mann., formerly placed in synonymy, is 

 a true species as shown me by Dr. Horn. Europe (Sweden, Finland).

392. L. erythroptera Kirhy. 



A variety of canadensis Fab. is almost certainly variicornis Dal- 

 man. According to Mr. E. A. Schwarz (Ent. Am. ii, 161) cinna- 

 vioptera Hald. is a synonym. Oribrlpennis Lee. is another variety. 

 From an examination of a number of specimens of each of the 

 American forms I am led to believe the varieties named to be merely 

 individual variations in a variable species. The species as a whole 

 extends across the northern part of the continent from the Atlantic 

 to the Pacific, and down the Rocky Mountains to New Mexico.

 eastern Siberia to the mouth of the Amur. Col. Am. 147 ; Heyden,

CHRYSOMELID^E 



393. Donacia dentata Hoppe. 



This species remains unidentified in our fauna. It inhabits p]u- 

 rope and western Siberia. Heyden, 197. 



394. Zaug-oplaora scutellaris Sujf., snbsjnnosa Gebler. 



Mr. Schwarz takes this species at Detroit, Mich. ; my specimens 

 are from northern Illinois. Its occurrence elsewhere has not been 

 noted. Europe (France. Germany). Western Siberia. Heyden, 198. 



395. Crioceris asparagi Linn., var. maculipes Gebl. 



Introduced from Euroj)e about 1859 into Long Island, N. Y. ; it 

 is slowly spreading inland, and is abundant (Geneva, N. Y. ; Balti- 

 more, Md. ; Fairfax Co., Va.) Lugger. For figures of it in all its 

 stages; see Lintner's First Rep. N. Y. 239-46. It inhabits Europe 

 and Siberia. Hevden, 198.
