of the forewing, a broad black stignia, and dark costal margin of the hindwing. The 2 is dark brown with a 

 band of yellowish-red spots. The under surface is light yellow, in the $ dark olive-grey on the hindwing. Verj^ 

 widely distributed and mostly common in the eastern and southern States of North America, from Mexico 

 to Argentina and in all the West Indian Islands. — The light green pupa with darker green dorsal and lateral 

 stripes lives on herbs and changes into a light green pupa. 



H. andina Stgr. might be a dark local form of 'phylaeus. It differs by much broader blackish-brown andhia. 

 distal margins of all the wings, not being dentate on the hindwings. The costal-marginal part of the hindwing 

 is also much broader dark, also the veins and the inner-marginal part, so that almost two thirds of the surface 

 of the wings are dark. The imder surface is much more intensely spotted dark, especially on the hindwing, which 

 mostly are of an ochreous-brown ground-colour. From Cocapata (Bolivia). 



H. peruana Sf. nov. (180 f) is somewhat smaller than phylaeus and is very closely allied to fasciolata, peruana- 

 on the forewing scarcely different, the black longitudinal spot at most behind the upper cell-end being some- 

 what larger and thicker; the hindwing exhibits below the cell yet 2 small black longitudinal spots. The 9 is 

 much lighter yellow. The under surface is quite different: dull ochreous-yellowish, in the $ almost without 

 any reddish tint, the markings from above repeated in distinct, small, jet-black, wedge-shaped spots which 

 are smaller than above and all well separated by light veins. From Cuzco (Peru). 



H. fassli sp. nov. (180f). There only exists one $, for which reason its position is not certain. Thrice iamli. 

 as large as peruana, above light yellow as the $ of peruana with an ochreous-reddish tint, marked as there, 

 but the black markings particularly of the distal margins are much broader ; especially on the hindwing proxi- 

 maUy not dentately, but straightly defined; on the middle radial vein the yellow colour projects pointedly 

 towards the margin, whilst from the cell it is folloAved in an acute angle by a black discal angular spot; fringes 

 ochreous, towards the apex feebly speckled. The under siu'face is most peculiarly and differently marked. On 

 the forewing similar as above, but duller, the small subapical spots whitish, the anal angle lighter. Hindwing 

 likewise as above, but much lighter, the margins strewn with a violettish grey, the subcostal within the cell 

 distinctly whitish-yellow, below it whitish hairing; behind the inner-marginal fold there is a blackish longita- 

 dinal spot, the anal half of the wing more sand-coloured yellow. 1 $ from Cuzco (Peru), taken by Fassl. 



H. isonira Dyar (180 f ) is very closely allied to phylaeus; in the ^ the black margins are broader, almost isonira. 

 forming a proximally dentate band. The $ is only slightly darker than the cJ, the markings not so much flown 

 together. Beneath light yellowish, hindwings tinted grey with a lighter discal band, bordered by a dark red, 

 sharplj^ broken, the lower segment straighter than in phylaeus, not spotted black. From Peru, rising to altitudes 

 of 14 000 ft., in July and October. 



H. fasciolata Blch. {= emma Plotz) (180f) is somewhat smaller and stouter than phylaeus, of a deeper fasciolata. 

 reddish -yellow, above somewhat more intensely marked black; also the $ is marked and coloured almost lilie 

 the cj, instead of the scent-stripe there are 3 small black spots. The principal difference consists in the very 

 much black-spotted under surface. From Chile. 



H. fulva Blch. (= grynea Ploiz, lujana Plotz, antarctica Mab.) (180 f) is larger, especially the 2 is fuh-a 

 much more intensely marked black; beneath the $ is much strewn with brownish-grey, with a white postdiscal 

 macular band and cellular spot, the ^ is light yellow with small black punctiform spots and a black proximal 

 margin of the forewing. Chile. 



78. Genus: Eryniiis Schrk. 



The antennae are somewhat longer than in Hylephila, but still shorter than half the costal margm; 

 the club is longer, the hook-shaped apex better developed. The scent-scale stripe of the ^ is broader and extends 

 to the rise of the lower median vein. Otherwise not different from the preceding genus. 



E. comma L. (= virgula Retzius) has been dealt with in the palearctic part (p. 348, t. 88 d) and 

 occurs in a number of forms in America. — f . matlitoba Scddr. (180 f, g) is a slender form above lighter yellowish- Manitoba. 

 brown, -with slightly darkened margins above. Beneath on the hindwing the whitish marginal band is quite 

 coherent and sharply angled, the ground-colovir dark brown or with a greenish tint. To the north as far as 

 Canada, to the south as far as Colorado and North California. — f . viridis Ediv. ( 1 80 g) is on the hindwing beneath viridis. 

 distinctly green, the marginal band being often interrupted. — f. juba Scddr. has above somewhat broader /((6a. 

 darkened margins of the wings ; beneath the apex of the forewing is more darkened, the spots of the hmd-«ings 

 are less coherent. — f. nevada Scddr. (180 g) is smaller, above the (J is of a deeper yellowish-red, the margins nevada. 

 are less darkened; beneath the spots of the hindwing are very small on a greyish-green groinid. — f. Idaho Edw. idaJw. 

 (180 g) is a very light form in which the marginal darkening is reduced almost to a marginal line; the hindwing 

 is beneath light yellowish-grey, the small light spots are little prominent. — f. Colorado Scddr. (180 g) on the Colorado. 

 contrary is very much more darkened, also the basal area. Hindwing beneath dark greenish-grey with angrilar, 

 torn, light spots. — f. Columbia Scddr. (180 h) is above almost just the same as beneath, but quite light sand- Columbia. 

 coloured yellow, almost unmarked, still lighter than idaho. — f. oregonia Edio. (ISOh) resembles manitoba oregonia. 

 above, but the $ is much lighter and more similar to the (J, beneath light yellowish-grey as idaho, with a very
