Secondaries pale ochreous or pink, shaded with bright yellow along inner margin and lower 

 portion of outer margin; a large black patch on costa near base of wing, from the lower outer 

 margin of which a narrow curved black line extends to near inner margin, occasionally the whole 

 basal area may be suffused with black as on upper side; other maculation as above. Expanse 

 37-43 mm.; 9 similar in maculation to the s , but with the markings more sharply denned; 

 generally brighter in color, the primaries being either bright yellow suffused along costa and at 



base with deep pink, or else entirely pink. Beneath the ground color 

 of both wings is deep orange-yellow shghtlv suffused with pink. 

 Expanse 40-43 mm. Transition forms leading over to ab. denudata 

 Neuni., in which all the maculation is obsolete, and to form alt. 

 shastaensis Behrens, a melanic form from high altitudes, are not rare in 

 themalesex. Described from 10 t? <?,3 9 9 , in collection Barnes, from

 [Variety uniformis Cockerell is based on a male collected by 

 Mr. S. A. Rohwer south of Island Lake, Colo., September 2, 1905, at an 

 altitude of 11,000 feet. The ground color of the wings, above and 

 below, is a rather light ochreous yellow, the secondaries above a little 

 brighter and clearer than the primaries, but the difference is hardly 

 noticeable. There is no yellow shade beyond the discal spot on 

 primaries. The form and markings are as in eglanterina, not as in he ra.]

 and Santa Clara Counties, Cal.] 



Larva. — Stage I: [From Manitou, Colo., received from Prof. C. V. Riley; Pergande's notes, 

 July 22, 1877, state that larva? were found by Prof. Riley at Manitou, feeding on willow; a half 

 grown larva was blown, and marked 889P.] Length 5 mm. The spiniferous tubercles are 

 arranged, as in Automeris io, in eight rows, those of the two rows, one on each side of the median 

 Line of the body, and the subdorsal ones being the larger and longer, while those on the side of 

 the body become shorter and smaller as they approach the under side of the body. The spine- 

 bearing warts are larger and swollen compared with those of A. io. The dorsal spines on the 

 prothoracic segment differ from those of A. io in having the trunk spmulated, the spinules being

long and each bearing a long, tapering hair; the main spine is pale but ends in two long black 

 forks, each tine of which is two-tliirds as long as the trunk of the spine itself, while the bristle 

 arising from each fork is as long as the later. The spines of the two lower rows are spinulate 

 on the trunk but are pale throughout, while the larger ones on the back are dark at the end, 

 being pale at the base. The dorsal spines on the abdominal segments differ from those of the 

 thoracic segments in having a somewhat verticillate arrangement of the large five or six terminal 

 spinules, all being pale except the terminal one, which is considerably larger than the others. 

 The single median spines on the eighth and ninth abdominal segments, respectively, occupy 

 the same position asiiii. io, but are larger in proportion and are not forked as they are in A. io;
