provided -with lateral sotte; in $ simple. Palpi slightly aseending; third joint imssiug beyond, the 
front, second joint slightly curved n]»ward, the scales beneath the joints being short; tliird joint 
half as long as the second, porrect, being directed forward at a slight angle Avith the second joint. 
Thorax short; the scales of the protliorax distinctly marked. 
Fore Avings hardly one-half as long as broad; costa A’ery slightly concaA^e in the middle, 
toAvard the tii) a little convex; outer margin oblique; internal angle obtuse; the inner edge near 
the base of the wing full in 3 , in the $ straight. Venation: A short subcostal cell, the discal 
vein of both wings forming a regular curve. PTind wings with the costa long and straight, apex 
subrectangular; from thence the.outer margin is longer than usual and slowly rounded to the 
not very distinct internal angle. The wings reach to the basal two-thirds of the abdomen. 
Legs pilose, the anterior femora densely" so, those of the 9 Avith longer scales, and more 
irregularly and thickly pilose. 
Abdomen long, cylindrical, with lateral tufts, ami tip of $ slightly tufted. 
In coloration the species are generally gray, Avith dark streaks running parallel to the A*enules. 
There is a distinct basal longitudinal mesial streak and an outer very distinct geminate curved line. 
The long, slender, acute pal])i, the high conical tufts on the verier of the head, the shape of 
the Aviugs, their markings, and the A^enatioii are sufficiently diagnostic of this genus. 
Egg. — Shape of a Hattened si)hert)id, the upper pole somewhat conca\’'e, a little broader at the 
base than at the top. Surface of the shell covered Avith polygonal areas, Avhieh Amry somewhat in 
shape, size, and distance Jipart, the intersptmes being rather broad. 
Larva. — Head round; body elongated, rather slender, of nearly uniform thickness, Avith a low 
rounded black dorsal knob on the eigldii abdominal segment; no other armature except a i)air of 
snbdorsal black Avarts on tlie tirst abdominal segment. Anal legs slender, ui)lifted. Three lateral 
black lines, and base of all the legs with a black patch. Freshly hatched larA^a : Head very large, 
body tapering behind; end. of bod}' Avitli the slender anal legs, which are bookless and slightly 
reversible, held up while in motion. Two subdorsal conspicuous papilhe on the tirst abdominal 
segment, and two siinilar but much smaller ones on tlie eighth, which in the last stage form the 
single dorsal knob. Glandular hairs unusually long, thick, clavatc, black, clear, and colorless at 
the end. 
Cocoon. — Thin, loose but somewhat tough, covered Avith bits of earth, etc., and spun on the 
surface of the ground. 
Fuim . — Cremaster conical, cleft at the end, each fork blunt, and bearing three hooked setfe. 
GeograjgMcal iltstrlhuiion. — Of the two species known, one [interna) is eonlined to the 
Appalachian subprovince and the other ranges through the Appalachian and the Austroriparia i 
siibproA'inces. 
(EdemaHia senata Dnice (Biol. Ceutr. Amer., p. 235, id. 25, iig. 1), from Jalapa and Panama 
(volcan de Ohiriqui), has the shape of fore wings and the markings of a Dasylophia, and I am 
quite of the oimiion that it is not an (Edemasia (Schizura); the two black round spots near the 
inner angle are just as in 7>, anguina. In fact I regard it as very closely related to 1). angiiina.f 
and hence as a representative species. 
Mr. Neuiuoegen has kindly shown me Nysialea amazonica Stand., from Brazil, and Avhich is a 
genuine Dasylophia very closely related to our D. anguina. If this is so, then the genus ranges 
through the Mexican (‘-^Sonoran”) subprovince and the Central American region to Brazil. 
A. Indiana Grote I am inclined to regard as a Noctnid. ^

* I copy from Nenmoogeu and Dyar’s Kevision the following description of this moth, Avhich I have been 
unable carefully to examine: 
^‘Xijiiialca indiana Grote, Papilio, iv, p. 7, 1884. 
“Anteriorpart of thorax with a dull yellowish patch as in Datana, bordered by black ; the rest gray. Fore Avings 
nitich elongated ; antennas simple, ciliate, the cilia longer at base, a tuft on each joint at each side. Primaries cinereous, 
paler on the disc, distinctly mottled; subbasal line faint, T. a. and t. p. lines close together, straight, parallel, 
narrow, blackish-hrown, equidistant from the indistinct hhick discal ringlet. On A'eins 2-3 (viih-viii), near the 
base, a black patch; another hetween veins 3-4 (vii-Va) Just outside t. p. line. Suhtorminal row of small black 
dots, two in each interspace, and terminal black shaded spots. Secondaries blackish, pale at base. Expanse, 40 mm.
