192 THE CANADIAN ENTOMOLOGIST. 



LEPIDOPTERA FROM MARSHALL PASS, COLORADO. 



The late Mr. W. S. Foster sent me some years ago a lisl of Lepidop- 

 tera taken by himself in 1888 at Marshall Pass, Colorado, which deserves 

 to be put on record as a contribution to the knowledge of alpine ento- 

 mology. The collecting was done at altitudes from 10,000 to 13,000 

 feet, on the slopes of the Continental Divide and Mt. Ouray, on the north 

 side of the railroad track. This is in Saguache county, and about forty 

 miles from the district in Custer county, of which the alpine insects are 

 recorded in Can. Entom., 1890. The list is as follows : — 

 Papilio zolicaon^ Bdv. Pyravieis kwitera, Fb. 



" asterias, Fabr. Ccefionyjnpha ochracca, Edw. 



Parnassitis sminthetis^ D. & H. Erebia viagda/ena, Strk. 



Pieris sisymbri, Bdv. Chionobas clwyxus, Westw. 



" protodice, B. & L. " taygete, Hbn.? 



" oleracea, Bdv. Lyccetia shasta, Edw. 



Colias meadii, Edw. Chry$opha7ius snotvi, Edw. 



" alexatidra, Edw. Lycxtia melissa, Edw. 



*' scudderii, Reak. Pyrgiis centaurex, Ramb. 



" eurytheme, Bdv. Deilephila liiieata, Fb. 



Argynnis freya, Thunb. Alypia lorquinii^ G. & R. 



" eiayjioffie, Edw. Gnophaela vermiculata., G. & R. 



" heletia, Edw. NemeopJiila pianiaginis, Auctt. 



Eiiptoieta claudia. Cram. Plusia Jiochenwarthi., Hoch. 



Melitcea brucei, Edw. Drasteria erec/itea, Cram. 



" atiicia, Auctt. Amer. Botis tiirjualis, Grt. 



" palla, Bdv. 



Afel. briicei is the real anicia, and anicia, Auctt. Amer., should appar- 

 ently be called i/ieglashanii, concerning which see 12th Rept. Colo. Biol. 

 Assoc. Mem. plantaginis of the Colorado Mountains would now, I 

 suppose, be referred to peirosa, Walk. 



In Prof. J. B. Smith's list of Lepidoptera, while petrosa is accepted as 

 distinct, " hospita, Schiff." is referred to it as a variety. This latter is, 

 however, a variety of the European JST. plantaginis, L., and consequently 

 the American hospita-Wke. aberration apparently requires a new name. 

 Boiis turmalis is now referred to itysaiis, Walk. The doubtful Chion. 

 taygete is very possibly the species lately named C. brucei by Mr. W. H. 

 Edwards. 



Of the thirty-three species enumerated, about half may be regarded as 

 specially alpine ; the others occur also at much lower elevations.
