Wright's figures (PI. VII, Figs. 54, 54b, 55, 55b, 55c) we think may 

 all be referred here. The larva of hyantis has been briefly described 

 by Mead from the Yosemite Valley (Psyche, Vol. II, p. 183) and 

 seems to show points of distinction from the description of the larva 

 of ansonidcs found in Edward's Butt. N. Am., Vol. II. ; careful breed- 

 ing and observation by collectors on the spot is however very essen- 

 tial to establish the relationship of the forms and the number of yearly 

 broods. 



Lotta Beut. is in our opinion a race of this same species from 

 Utah, Arizona and the Rocky Mt. region in which the discal spot of 

 the primaries has become greatly enlarged and quadrate; Verity has 

 redescribed it under the name of bclioidcs; in Utah it occurs from the 

 end of April to the beginning of June and we have a few specimens 

 from Glenwood Spgs., Colo., taken in May; our Arizona material is 

 unfortunately undated ; these Arizona specimens are intermediate 

 between hyantis and Utah specimens of lotta in the size of the discal 

 spot and the amount of green on underside of secondaries; they are 

 figured by Wright (1. c. PI. VII, Figs. 54a, 56b).

Although it is extremely difficult to point out any definite means 

 of separation between this species and crcusa we incline to think it a 

 distinct species and not a summer form of the preceding as surmised 

 by Verity. The larger size, greenish white ground color in the $ in 

 contrast to the pure white of crcusa, the tendency in the $ 's to show 

 ochreous tinted secondaries and the narrower and yellower character 

 of the markings on the underside of the secondaries with less of the 

 pearly hue on the white portions all point to a specific distinctness; 

 we have further the fact that the larvae as described by Mead and 

 Edwards do not appear identical ; our dated specimens from the lower 

 regions of California (Alameda Co.) show no date later than May; 

 specimens from Mineral King, Tulare Co., at an altitude of about 

 10,000 feet, were captured in the first week of July, but it is extremely 

 improbable that they were preceded by a spring generation. The 

 species is well figured by Holland (1. c. PI. XXXII, Figs. 24/25) and 

 Wright's figure (PI. VII, Fig. 57c) evidently represents this species 

 also; the type from Coll. Oberthur is figured by Verity (1. c. PI. 37, 

 Fig. 20). The species extends northward into Alaska and eastward 

 into Colorado where it has received the name coloradensis Hy. Edw. of
