vein more extensively white and on the lowest radial branch finely continued to the margin; the other branches 
are but slightly white at the place where they rise. Hindwing of a purer white. Expanse of wings: 30 mm. 
Arizona. — bellamusa Dyar (45 a) is larger, the white markings somewhat broader, particularly the branches bellamusa. 
at the lower cell-end more distinctly white, so that a tricuspidate marking is produced with a middle tooth 
extending to the margin. Hindwing somewhat more brownish. Mexico (Zacualpan). 
N. coronides Drc. (45 a) is the largest species, green with a more brass-like gloss, the costal-marginal coronides. 
stripe more mixed with brown, like the fringes, the median not white, at the lower cell-end a minute white 
spot strewn with brown. Hindwing more brownish. Mexico (Zacualpan, Guerrero). — pendula Ottolengui, on pcndula. 
the contrary, like the other species from Arizona, is a more intensely white form, particularly the cellular spot 
is of a purer white. 
156. Genus: l*sectrotarsia Hmps. 
Distinguished from Chalcopasta by the rounder frontal projection with a raised edge, but without the 
central appendage, with somewhat shorter, but also porrect palpi and a purely haired thorax without tufts, 
the abdomen being tuftless, too. The anterior tarsi exhibit outside on the first joint a row of 7 spines. Only 
3 species have been described. 
P. fuscirena Hmps. (45 a). Forewing yellowish-white, strewn with brown, the median area of a bright fuscirena. 
lemon-colour, the margin light yellow, the maculae are in white rings and strewn with brown, the reniform 
macula is centred with blackish. Hindwing of a pure white. Argentina. 
P. flava Dgn. (45 a) has cpiite yellow forewings being powdered with red-brown only at the costal flava. 
margin and postmedianly, with reddish-brown transverse lines, the posterior line being finely dentate, the 
macidae are feebly marked with red-brown. Hindwing light yellow with a darker central luna and subterminal 
band. Peru. 
P. tamsi Giac. is as large as fuscirena ; forewing above uniformly coloured fine light greenish-ochreous, iamsi . 
hindwing white with a brownish marginal band. Argentina. 
157. Genus: Enargia Hbn. 
Proboscis developed, palpi erect, frons smooth, thorax only clad with hair, and tuftless like the abdomen; 
but the latter at the base and laterally hairy. Beside several palearctic species also a North-American species 
is known. As to further particulars cf. Vol. Ill, p. 233. 
E. decolor Wkr. (45 a). Porewing orange-red, strewn with brown, with brown transverse lines and decolor. 
a broad brown postmedian shadow as far as the lower cell-end; the large maculae are surrounded by brown, 
the reniform macula with a blackish spot at the lower cell-end. Hindwing light yellow with a reddish tint. A 
very variable species. — infumata Grt. is densely strewn with a brownish grey. — niia Strd. ( — ab. 2. Hmps.) infumata. 
has much lighter yellowish-white forewings but feebly speckled dark. — sia Strd. ( = ab. 3. Hmps.) is also light m . m - 
yellow, but strewn with red-brown and with reddish markings. From Canada to California. 
158. Genus: l>errinia. Wkr. 
The genus contains but one small, rather slim species distinguished from the preceding one by a slight 
roundish frontal projection with a horny plate below it; the hairy thorax is covered with scales and tuftless, 
like the abdomen. The anterior tibiae exhibit inside one claw and outside 2. 
B. stellata Wkr. (45 b). Thorax pinkish crimson, forewing olive-yellow, at the costal and distal margins stellaia. 
broad pink, in the disc with 2 silvery white small spots in black rings, and before the pink marginal area with 
a subterminal row of small white spots. Hindwing on the yellowish ground densely powdered with pink. 
— In the form Henrietta Grt. the two small discal spots are likewise in pink rings, the row of white spots is henrietta. 
less prominent, and the hindwing is not pink but ochreous yellow.—In cinocentralis Strd.(= ab. 1 .Hmps.) cinocentrci- 
the proximal one of the two small discal spots is centred with grey. From Massachusetts and New York to hs 
Florida. 
159. Genus Grt. 
The chief characteristic mark of this genus is the large horny frontal projection, shaped like a reverse 
heart, with raised edges, the lower edge being extended into a somewhat upturned point, below it a horny plate; 
proboscis developed; palpi rather porrect; thorax clad with large rough scales, in front and behind with loose 
tufts, the ends of the shoulder-covers somewhat upturned. The anterior tibiae exhibit inside at the end a 
long bent spine. Abdomen tuftless. Several species partly very difficult to separate, from North and Central 
America.
