Four of the type males of coronada are deep red-brown with primar- 

 ies crossed by two narrow white lines and with siibterminal line faintly 

 indicated by a series of irregular brownish patches. This is the form 

 described by Dr. Dyar as valcns. The fifth $ type has the primaries 

 suffused with gray scaling to such an extent that the red-brown 

 ground-color is more or less hidden ; the white lines are edged nar- 

 rowly \\ith red-brown, which shows more prominently against the gray 

 back-ground than the lines themselves. ^lore extreme forms than 

 the type are before us in which the primaries are light gray, crossed 

 by two very distinct reddish lines bordered with white, the basal one 

 outwardly, the median one inwardly ; an irregular dark brown sub- 

 terminal line shaded broadly inwardly with lighter brown is also pres- 

 ent. In other specimens of the red-brown form the white lines have 

 become broadly suffused and form bands of white, about 1.5 mm. in 

 width, across the wings. The 9 9 are apparently less subject to varia- 

 tion, being all of the pale ochreous form. If it is considered necessary 

 to retain a name for each form, coronada could be applied to the gray 

 form, whilst coronada al?. I'alciis would designate the dark red-brown 

 male. 



With regard to the early stages we have received ova, dried larva 

 and pupa from Mr. Biederman who breeds this species each year. The 

 egg is oval, pure white, with a greenish micropyle, situated at upper 

 end; length from base to microi)yle 2 mm.; breadth 1.5 mm. The 

 eggs are laid in even rows during the latter part of July, according 

 to Mr. Biederman, on Qttcrcus arlzonica, hatching early in August. 

 The young larvae are silvery white, turning when half grown grayish- 

 brown. In the day time they rest in clusters on the bark, marching 

 out during the late afternoon in single file to the leaves and feeding 

 at night. They hibernate about ■;4 grown, pupating during the latter 

 half of April. The dried larva before us is very similar to the 

 European' qucrcus, covered with a thick coat of red-brown fur, and 

 numerous long silk)' white hairs. We can discern no trace of mark- 

 ings; the stigmata are bright 3'ellow. The cocoon is a loosely spun 

 web of black-brown silk, through which the pupa is indistinctly visible.
