basal marking on the hinclwing. The larva resembles that of eglanterina, but inclusive of the thorns it is all 
black with an undulating whitish substigmatal line; it lives on Salvia. 
32. Genus: Coloradia Blake. 
In the structure likewise very near to the 3 preceding genera; second inner-marginal vein of the 
hindwing present, too. Shape of wings narrower, hindwing smaller. Antennae in the $ bipectinated, in the $ 
serrated. Cross-vein in both wings stronger and not angled; in both wings the origin of vein 5 is a little below 
the upper cell-angle, 6 and 7 arise from the same place or on a short stalk in both wings. The larvae of pandora, 
according to Aldrich *), are considered a delicacy by the Mono Lake Indians who collect the larvae coming 
down from the trunks for the sake of pupation in July, by cutting ditches around the trees; the insects are then 
roasted in earth which has been made hot by fire, passed through a sieve, spread out on bark for 2 days, 
whereupon they are preserved cool and dry in bags and prepared for meals like “Irish Stew - '. Aldrich found 
the tough “delicacy” to taste insipid and saltless, somewhat like linseed oil. The Indians call this food: Pe-aggie. 
Type: C. pandora Blake. 
C. pandora Blake (= loiperda Dyar) (120 g). Forewing strewn with black and white, hair-shaped pandora. 
scales, with 2 notched black transverse lines which are more intensely bordered with white on the inverted sides 
especially at the costal margin; at the cross-vein a small black spot; the irregularly notched subterminal line 
is distally bordered with whitish; fringes speckled white on the ends of the veins. Hindwing whitish with a 
very feeble flesh-coloured tint, somewhat more distinct at the inner margin, with a black median spot, a 
notched postmedian line and a marginal band in which we notice a feebly lighter indistinct subterminal line. 
Larva on Pinus jeffreyi, at Lake Mono in altitudes of 7000 ft., biennial and pupating without a web in the 
soil; evolution in spring. Rocky Mts., from Montana to Mexico. 
C. davisi B. <£• Benj. (120 g) is closely allied to pandora and similarly marked, smaller, more variegated, davisi. 
blacker, without any brownish tint, the subterminal line more conspicuous white. Hindwing and the under 
surface intensely tinted pink. White Mts., Arizona. 
C. doris Barnes (= lois Dyar) (120 g) is much smaller than pandora, the wings are much less scaled, doris. 
more monotonously grey, particularly the $ dull brownish sooty grey; the subterminal line is scarcely scaled 
white distally. Hindwing in the <$ almost hyaline whitish, only at the inner margin very feebly haired reddish, 
in the $ quite sooty grey. Colorado. 
C. luski B. & Benj. bears the same relationship to doris, as davisi to pandora, blackish-grey, scantily luski. 
strewn white, with faded markings; hindwing intensely tinted pink like the whole under surface. Sexually 
dimorphous, in the $ the hind wing is much darker and more densely scaled than in the White Mts., Arizona. 
Expanse of wings: $ 57 mm, $ 60 mm. 
C. lindseyi B. cb Benj. is allied to pandora and may be regarded as its northern race; somewhat darker lindseyi. 
than pandora, the hindwing more pinkish,; in the $ the forewing is much duller and more brownish, hindwing 
and under surface more suffused with reddish than in pandora. California, Oregon. Expanse of wings: 
$ 78—80 mm, $ 82—87 mm. 
C. bonniwelli B. & Benj. is similarly marked as pandora, smaller, in the <$ darker, more variegated, bonniwelH. 
rather like davisi, in the £ more softly scaled, more as in doris, but with more contrasting markings; hindwing 
and wings beneath as in pandora. New Mexico. Expanse: 64—70 mm, $ 75 mm. 
C. chiricahua B. &- Benj. is still smaller, the ground of the wings more intensely strewn with white, chiricahua. 
the black transverse lines therefore more prominent, the subterminal line very distinctly white outside. Hindwing 
almost white, with a slight pink hue; without any brownish tinge. Under surface lighter than in pandora and 
without its brownish dingy colour. Expanse of wings: 60 mm. According to a from Arizona. 
C. duffneri B. d: Benp is similar to clmi'icaihna, largei, intensely stiewn with white, paiticulailv the duffneri. 
median area contrastingly white; transverse lines strong, subterminal line only marked by the distal white 
dusting; discal spot very small. Hindwing and under surface more intensely red. Expanse of wings: 67 mm. 
Cochise County, Arizona. 
C. euphrosyne Dyar (120 g) is more brownish, the median area somewhat more prominently white, the euphrosyne. 
transverse lines broad, faded, scarcely notched, discal spot small. Hindwing variable, in the inner-marginal 
half dark pinkish carmine, marginal area more or less broadly blackish-grey, with a black discal spot which 
may be either isolated or also contained in the more or less broad brownish-grey median band. Mexico City.
