inner half (within the discal vein) is deep orange yellow, the outer paler (in both wings). The 

 black cloud or patch is wider and rounder than usual. 



Under side of wings much paler than in the normal form, especially in the outer margin 

 of the wings. The broad median band or median third of the wing is brown on the edges and 

 regularly scalloped externally, and irregularly so on the inside; the band is much more dis- 

 tinct and more regularly scalloped on the hind wings. The ocelli are smaller than above, and 

 not so round. 



Expanse of fore wings, 9 150-168 mm. 

 Length of fore wing, 71-80 mm. 



Ocellus of fore wings, 9 by 8; of hind wings, 8 by 8 mm.; on the under side of fore 

 wings, 8 by 8 mm.; of hind wings, 5 by 6 mm. 



Whether this is a dry geographical race, peculiar to Arizona and the neighboring nearly 

 rainless, hot, arid regions, remains to be seen when we have more specimens for examination. 

 It is not decidedly paler than eastern examples and has considerable black in the spots and bands. 

 Did I not have a nearly similarly pale 9 from the Eastern States (exact locality unknown), I 

 should be inclined to regard oculea as a climatic variety, but until we have seen the larva, we 

 should hesitate about regarding it as such. [Var. oculea was taken by Snow in Gallinas Canyon, 

 N. Max.] 



[Mr. J. Doll writes (litt., July, 1912) that the type female of T. polyphemus oculea "Differs 

 in pattern on the under side of hind wings in the wide bands almost uniformly on middle third," 

 and adds, "all our oculea have the marked dark dash extending basally from the eye-spots on 

 the primaries." Mr. Doll further expresses the opinion that Druce's figure of T. aurelia in the 

 Biologia Centrali-Americana is " a fine figure of the 3 of oculea." Strecker (litt. to Dr. Packard) 

 also expresses the opinion that aurelia was oculea.] 



[A female from Albuquerque, N. Mex., June, 1902 (J. G. McNary), must be referred to 

 oculea, although it lacks the evident dark shade basad of the ocelli on the primaries. It is 

 large (length of primaries about 69 mm.) and has little light color beyond the dark submarginal 

 band, agreeing hi this last character with the Mexican race (PI. LVI, figs. 3, 4) as well as with 

 oculea. The general color of the upper surface is very warm but light ochre-red, and the white 

 part of the upper section of the subbasal band on primaries is very broad and conspicuous. 

 On the under side the median broad area is shaded with a very fine cinnamon-red, while the basal 

 part of the secondaries is very white. The red median area on the hind wings is very broad. 



I do not know how far north oculea occurs, but at Boulder, Colo., the insect is smaller, 

 with a strong white or pinkish shade beyond the submarginal band, and must be referred to 

 polyphernus proper. There are, however, several varietal forms: 



Var. a. — General color above warm reddish-ochreous, like the Albuquerque oculea, but 

 region of wings beyond ocelli and before submarginal band more blackish; pinkish white shade 

 beyond submarginal band very distinct; ring round hyaline area on primaries (as in aU Boulder 

 specimens) pale yellow (in the Albuquerque oculea it is cinnamon); under side with more 

 blackish scales than in Albuquerque oculea; band on hind wings very much narrower, and 

 basal part hardly whiter than the part beyond the median band. Female. Boulder, July 20, 

 1906 (F. W. Ptohwer). 



Var. b. — Strongly vinaceous-red ; shade beyond submarginal band delicate pale lilac; area 

 around ocelli of hind wings strongly blackened ; under side also strongly vinaceous, the lighter 

 parts of the secondaries suffused with pink; the median band of secondaries broad, formed 

 essentially as in the Albuquerque msect, but darker and more vinaceous. Male. Boulder, 

 June 3, 1912. Received from Miss Eva Miller. The female of this form (except that it lacks 

 the black suffusion around ocellus of hind wings) is figured by Holland in The Moth Book, PI. 

 IX, fig. 1. 



Var. c (ab. nov. olivacea). — Ground color above pale grayish olivaceous; shade beyond 

 submarginal band white. Under side marked like var. b.; but colors olivaceous, with no 

 vinaceous or reddish whatever; dark markings deep brownish olivaceous; basal part of second-
