'^riiif; seems to lie a more eomnidii species in California llian in llie East- 

 ern States, (lioiiuh il is widely diU'iised over the colder [loit'on and. alpine, 

 reirioiis of the country east of the liocky Moiinlains. It is ([uite closely allied 

 to Cm. jxjlata, lint dill'ers in the fore wings heing more olilnse at tli(; apex, and 

 the eosta more convex. Jt may he recognized hy the nnmerous, jiarallel, 

 scalloped, lila(d<isli-i,M-ay lines; the large, distinct discal dot; the general steel- 

 l)lu<! gray color of the; winirs; the very few yellowish scales; and I)y the 

 entindy clear, pale, smoky, tlesh-colored hind wings. 



On examining }iV. Guenee's collection, I recognized it from memoiT as 

 his Sparganiu mag)iollat(i ; and Mr. I\lorr;son has since.' iidinined me thai he 

 identified it as sncdi from I\I. Guenee's deseripliou, with which it airrees W(dl. 



I can tind no dilferences lietween two specimens from the Atlantic States 

 (one G. and IJ.'s type- from Bulliilo, and one from ]\lain(!, collected liy myself), 

 and twelve examples Irom California, Cdllected \)y .Mr. Edwards. Jt sei'nis 

 to 1)0 mucdi more common in Caliiornia than in the East. It is nearly r(dat(;d 

 to (j. polata. 



The Ctdorado male (length of fore wing, (>2 inch) is much larger than 

 three feinales from New York and Northern New England ; the length of 

 the wing of the largest heing 0.55 in(di. The Calih)rinan s])ecimens are also 

 much larger (the fore wing of the largest female ineasuring 0.63 incdi). Of 

 nine Californian specimens, three are of the same siz(Mind the rest larger tiian 

 eastern examples. There is, however, scarcely any dillerence in the shape of 

 the wings, though the Caliii)rnian specimens have on the wlude very slightly 

 more acnle wings.
