479. Neoclytus erythrocephalus Fab. — Tliis species occurs in Europe, in 



Dalmatia aud Istria in the Adriatic Sea. It is common here, and in- 

 liabits nearly every portion of our territory eastward from the Rocky 

 Mountains. Mr. Fanvel says this species should be erased from this and 

 the European catalogue, having been merely an accidental importation 

 into Europe from America. 



480. Rhagium inquisitor Linn., indigator, miniitum Fab., var. lineaium Oliv., 



investigator Muls. ; var. investigator Mann.. 1852. — Common from Florida 

 to Alaska in the pine regions; Mexico. Kamtschatka, Japan, countries 

 of the Amur, the pine regions of Siberia and Europe. Col. Am., 149; 

 Heyden, 192. This widely distributed species offers varieties which 

 have been considered specific. Their identity seems to have been suffi- 

 ciently established by Kolbe, Entom. Nachricht, 1884: lineatum is the 

 'general American form; investigator Mann, occurs in Alaska, and to 

 some extent on the Pacific slope. 

 4S1. Acmeeops pratensis Laich, strigilata Fab., var. ustnia Gebler ( fulvipennis 

 Mann., longiceps Kirby, semimarginata Eand.).— From Hudson Bay to 

 Alaska, southward to Maine and northern Michigan, and down the 

 Rocky Mountains to New Mexico; California; alpine and northern 

 Europe, many portions of arctic and eastern Siberia, northern China; 

 the var. ustulata Gebler is found throughout eastern Siberia and in 

 Kamtschatka, and is the prevailing American foim, 1. c. 235; .T. A. P. i, 

 312 and 323; Annals and Mag. Nat. Hist. 1870, v; Col. Amur. 148; 

 Heyden, 194. 



482. Leptura 6-maculata Linn., G, fasciata Fab. — Hudson Bay southward 



to Lake Superior and Michigan, Mount Washington, N. H., northern 

 Europe, the Alps, western and eastern Siberia; J. A. P. i, 312 and 333; 

 Col. Am., 148; Heyden, 195. The varieties parallelopipeda Mots, and 

 dentatofasciata (Mann.) occurred at Nikolaevsk. Heyden. 1884, 228. 



483. L. canadensis Oliv,, Fab., var. variicornis Dalm. {erythroptera Kirby, cin- 



namoptera Hald.), Schonh. System Ins. i, 3, 482; var. cribriptnnis Lee; 

 very variable. Variicornis should be compared with erythroptera or 

 cinnamoptera, as a comparison with typical canadensis might be mislead- 

 ing {see Ent. Am. ii, 161, and Can. Ent. xxv, 278) ; it does not apnear in 

 ('at. iv. Across the northern part of the continent from the Atlantic 

 to the Pacific, through the Rocky Mountains to New Mexico, and also 

 in the Alleghanies. Europe (northern Germany; Russia); western and 

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

 Heyden, 196. Japan, Jour. Linn. Soc. xviii, 217. An entirely black 

 example was taken in Japan by Mr. George Lewis, 1. c. 

 Obs.— It is probable that in the progress of systematic investigation several 

 other species of the Cerambycidse of the two hemisi)heres may be found 

 to be at least racial. Maeklin, in his comparisons of related forms of 

 northern Coleoptera (Bidrag Kannedom om Sakallade, etc., 1855, p. 53) 

 mentions the following as close: Asemum striatum Linn, and maestum 

 Hald. ; Criocephalus rusticus Linn, and agrestis Kirby I Tetrojnum fnscum 

 Fab. and cinnamopterUm Kirhy \ Callidiuyn xneum DeG. aud cicatricosam 

 Mann.; Monohamiiius sutor Linn, and scutellatus Say.
