at the posterior end, too. On poplars, willows, alders and other deciduous trees. Cocoon thin, velvety, with 
intermixed hairs. — The butterflies are not rare in many districts. 
H. caryae Harr. (= annulifascia Wkr., carrye Eothsch.) (59 a). A rather imposing, brightly coloured caryac. 
species. Forewing pale yellow, with numerous red-brown streaks which set off the veins and cross the cell. 
Parallel to the border there run 5 or 6 bands of diaphanous, white lustrous spots; thorax marked brown. Canada 
and the United States. -— porphyria H.-Schdff., likewise from the United States, has the hyaline spots smaller, porphyria. 
very numerously and distinctly surrounded by dark. — propinqua Edw. (59 a) is the large and beautifully propinquu. 
marked southern form representing the species in Mexico and Central America; here the veins are very beautifully 
marked red, the reflecting spots are large and touch each other in the single chains. — mixta Neum. (— pseudo- mixta. 
carye Eothsch.) is the form from Arizona; the yellow ground-colour is thickly covered with brown, and the 
reflecting spots are likewise yellow, so that they do not contrast so much. — bicolor Wkr. (= pura Neum.) (59 b) bicolor. 
looks quite different from all the other caryae- forms, but it is reported to have been bred from caryae-larvae. 
Here the hyaline spots are not surrounded by dark, but they only rest, as unsealed patches in the uniformly 
light yolk-coloured ground-colour, so that only at a certain exposure to light or on the darkened background 
they are prominent as unclusted interspaces or lustrous, small reflectors. This form occurs in Arizona and Mexiko, 
we figure it from the latter country. — Larva with a black head, venter and feet above greenish white, speckled 
black, on the 4th to 10th rings with tufts of long black hair, standing together above the dorsum. Rings 4 to 
10 with long lateral hair-pencils; some long hairs are above the head, and at the sides there are white hair. It 
lives on the hickory-nut (Carya alba) and nut-tree (Juglans) and pupates in a cocoon intermixed with hair. In 
many places common. 
H. ingens Ediv. ( — scapularis Stretch) (59 b). Thorax dark yellowish-brown, vertex, tegulae, patagia ingens. 
and a median stripe on the thoracic dorsum white, abdomen yolk-coloured, forewing olive-brown with silvery 
white, small reflecting spots arranged in rows, similar as in argentata (59 b), but the spots at the costal margin 
much larger, like those in the submedian space. Hitherto found only in the Rocky Mountains, in Colorado 
and New Mexico. 
H. alternata Grt. (= albiguttata Esd.) is quite similar to ingens, but the thorax is uniformly mixed alternates 
with black and white, the ground-colour of the forewing is black, intermixed with small white scales, base and 
inner-marginal area are mostly more spotted. Mexico, Cuba. 
H. argentata Pack. (59 b). Head above yellow, body yellowish white, otherwise very much like the argentata. 
preceding. Ground-colour of forewings a beautiful yellowish brown, intermixed with small white scales, the 
reflecting spots being arranged in straight rows are of a bright silvery white, the hindwing mostly in the disc and 
before the apex spotted brown. — In subalpina French from the Rocky Mountains the thorax is of a brighter subalpina. 
red-brown and the forewing at the costa and proximal margin so profusely covered with ochreous-whitish, that the 
wings are of a pale colour here. — On the contrary, sobrina Stretch is a more monotonous form from the Cali- sobrina. 
fornian coast, the forewings showing a uniformly deep brown ground-colour and the silvery spots being smaller. 
From British Columbia through the Pacific States as far as Colorado, New Mexico and Arizona. 
H. andensis Schs. (59 b). As large as the preceding and also very much like it, but the spots of a andensis. 
fainter silvery gloss and somewhat diaphanous, though not hyaline. The ground-colour is profusely strewn 
with yellow and white atoms; hinclwings hyaline, in the apical part spotted brown. Abdominal dorsum brownish. 
Colombia; the figured specimen from the Quindiu-Pass (Central Cordilleras). 
H. affinis Eothsch. (59 b). Thorax darker olive brown, vertex, collar and patagia white, the latter affinis. 
with a thick black shoulder-dot. Abdomen yellowish-brown, with blackish hair on it. Ground-colour of the 
forewings uniformly dark olive-brown, the numerous silvery white macular rows somewhat irregular; a marginal 
row of white spots. Vera Cruz and Peru. 
H. hyalinipunctata Eothsch. (59 b). The ground-colour of the forewing more sepia-brown, watered hijdlini- 
witli white, the spots very large, purely hyaline, so that fine writing may be legible through the wing; the macular punctata. 
rows straighter, more regular than in affinis, at the border only small fine white marginal dots. Peru, the figured 
specimen from Cillutimarca in Bolivia. 
H. tessellaris Abb. dk Sm. (= antiphola Watch.) (59 c). Pale ochreous-yellow, wings thinly scaled, tcssellaris. 
traversed by yellowish hyaline bands, the antemedian one being broad, the postmedian one bifurcated towards 
the costa, the subterminal one irregularly composed of squares. Abdomen yolk-coloured. Canada and Atlantic 
States. — The bands may, in aberrations, vary in the shape: in ab. antipholella Strd. (— ab. 1 Hmps.) the two antiplioleUa. 
median hyaline bands are partly or entirely confluent. — In ab. tessellaroides Strd. (ab. 2 Hmp>s.) the spaces tessellaroi- 
between are of a darker tinge, and the two distal hyaline bands are connected with each other by a bridge. -—- 
meridionalis Eothsch. (59 c) is a large form from Mexico, which we figure from Mexican City; here the hyaline meridiona-
