NOTES ON EUCHLOE HYANTIS, EDW. 



BY KARL R. COOLIDGE, PALO ALTO, CALIF. 



The hisiory of Eiic/i/oe /lyanf is well illustrates the state of confusion 

 of some of the western Euchloei?ice. In 1871 W. H. Edwards described, 

 in the Transations of the American Entomological Society, both sexes of 

 a species of Etichloe (Anihocharis)^ which he called hyafitis, the types 

 coming from Mendocino, Calif In his Pac. Coast Lepidoptera papers 

 (Proc. Calif Acad. Sci., No. 22, 1876), Hy. Edwards writes: ^^A?ithocharis 

 creusa, Dbl. I have little doubt, from an examination of a figure by Mr. 

 Butler, of the British Museum, kindly loaned to me by Mr. W. H. 

 Edwards, that this species is the same as A. hyaiitis, Edw., which is well 

 known to occur in the Sierra Nevadas, and in other high lands of the 

 State. It is said by Dr. Behr to be far from rare in the neighbourhood of 

 Oroville, and has been subsequently taken by Baron R. Osten Sacken in the 

 Yosemite Valley, and by myself near Lake Tahoe. It is probably often 

 confounded with A. ausonides, but it is abundantly distinct." W. H. 

 Edwards, in his list of Rhopalocera, published in 1877, places it as a 

 synonym, and in his later list (1879) it is entirely omitted. In 1878, 

 however, Hy. Edwards changed his former opinion and gives it specific 



rank. 



Of the later authors Beiitenmuller (Revision N. Am. species of 

 Euchloe\) places hyaiitis as a synonym of creusa^ and describes as new, 

 under the name lotta, the form heretofore known as creusa. 



Creusa was named by Doubleday and Hewitson, and, according to 

 BeutenmuUer, the figure given in their " Genera of Diurnal Lepidoptera " 

 agrees well with hya?itis or possibly auso?iides. There is no mention of 

 hyantis in Holland's Butterfly Book or in the Check List of American 

 Macro-Lepidoptera published by the Brooklyn Entomological Society in 

 1882. Dr. Skinner* makes coloradejisis, Hy. Edw., a synonym of 

 ausonides, and places hyantis as a variety. The same writer in his supple 

 ment puts elsa, Beut., and iotia, Beut., as varieties of creusa. Smith in- 

 his catalogue gives hyantis specific rank, as does W. G. Wright (Butt. 

 West Coast). Dyar^ places hyatitis as a variety of ausonides. Dr. A. G. 

 Butler (Can. Ent., XXXI, 1899, p. 19), writes : " As regards E. creusa, I 

 believe to vary seasonably as much as its very close ally, E ausonia ; the 



tAm. Mus. Nat. Hist., x., p. 235-248. (1898).
