DISTRIBUTION OF COLEOPTERA. 131 



291. Cercus bipustulatus P.nik. 



A few individuals of this European species were once taken near 

 Boston, Mass., Horn, but any further record of occurrence has not 

 been observed ; var. suturalis Mots, is found in eastern Siberia ; T. 

 vii, 272 ; Murr., 233. 



292. Carpophilus hemipterus Linn., hiinncniatns Mels., flexnonHn Payk. 



Variable both in ornamentation and thoracic structure, cosmo- 

 politan. Florida, Canada, Alaska, are the extreme points of its 

 occurrence. I take it here mostly in boxes of dried fruit, as raisins, 

 currents, etc., brought from foreign countries. It also occurs in Si- 

 beria, 1. c. 277 ; Murr., 362; Heyden, 91. 



293. C. dimidiatus Fah., mutildtns Er., lurkhis Murr. 



" Occurs everywhere in our country excepting the Pacific coast. 

 Its original habitat was probably the West Indies, but it is now cos- 

 mopolitan," Horn, 1. c 278 ; Murr., 377-79 ; some of the points of 

 its occurrence are Florida, here in Pennsylvania, Ohio, Texas, New 

 Mexico, Colorado, Alaska. Mann., 1852. 



294. Epursea sestiva Linn., cdiirexinscula Mann. 



On this continent this species appears to affect the colder parts. 

 Canada, northern Michigan, New Mexico, Alaska, are all points in 

 its distribution. Mr. F. Blanchard found it in the mountains of 

 North Carolina {in Utt.) loc. cit. 299. Europe. Western Siberia. 

 Heyden, 92. 



295. E. luteola Er., iexana Crotch. 



Dr. Horn states that this species is becoming cosmopolitan. 

 " Originally occurring in our Gulf States and Cuba, it has spread to 

 Europe {Beiche) and Ceylon (Murray)," 1. c. 301. 



Obs. — Several species of Epurcea of the boreal and Arctic regions, 

 when those of both continents shall have been collected by some 

 competent entomologist, will })i\)bably be found identical. 



296. Nitidula bipustulata Linn. 



This beetle occurs in many countries, and has been introduced 

 here by commerce. It now extends from Florida to Canada and 

 westward to Colorado, whence I have specimens. West and east 

 Siberia ; Amurland, 1. c. 302. Heyden, 92 ; Heyden, 1886. 



297. N. rufipes Linn., ob.icnnt Fab., osshim Kirby. 



This sjjecies has likewise been introduced from Europe, and has 

 about the same American distribution, extending northward to Hud- 

 son Bay. AVest and east Siberia, 1. c. 303; Heyden, 92; Amur 

 Territories; Heyden, 1885.
