provided witli lateiiil setu-; in 5 simple. I'ldpi .slifilitly ascendinf;'; third Joint pas.sing beyoud. the 

 trout, second Joint slightly curved upward, the scales beneath the Joints being short; third Jiint 

 half as long as the second, porrect, being directed forward at a slight angle with the second Joint. 



Thorax short; the scales of the prothorax distinctly marked. 



Fore wings hardly one-half as long as broad: costa very slightlj' concave in the middle, 

 toward the tip a little convex; outer margin oblicpie; internal angle obtuse; the inner edge near 

 the base of the wing is full in i , iu the 9 straight. Venation: A short subcostal cell, the discal 

 vein of both wings forming a regular curve. Hind wings with the costa long and straight, ajiex 

 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 with longer scales, and more 

 irregularly and thickly pilose. 



Abdomen long, cylindrical, with lateral tufts, and tip of $ slightly tufted. 



In coloration the species are generally gray, with dark streaks running parallel to the \enules. 

 There is a distinct basal longitudinal mesial streak and an outer very distinct geminate curved liue. 



The long, slender, acute paljji. the high conical tufts on the vertex of the head, the shape of 

 the wings, their markings, and the venation are sufficiently diagnostic of this genus. 



7J//r/. — Shape of a flattened spheroid, the upper pole somewhat concave, a little broader at the 

 base than at the top. Surface of the sliell covered with polygonal areas, which vary somewhat in 

 shape, size, and distance apart, the interspaces being rather broad. 



Larrn. — Head round; liody elongated, rather slender, of nearly unif<irm thickness, with a low 

 rouiuled black dorsal knob on the eight ii abdominal segment; no other armature excei)t a pair of 

 subdorsal black warts on the iirst abdominal segment. Anal legs slender, uplifted. Tliree lateral 

 black lines, and base of all the legs with a black patch. Freshly hatched larva : Head very large. 

 body tapering behind : end of body with the slender anal legs, which are bookless and slightlj' 

 reversible, held up while in motion. Two subdorsal conspicuous papilla} on the first abdominal 

 segment, and two similar but much smaller ones on the eighth, which in the last stage form the 

 single dorsal knob. Glandular hairs unusually long, thick, clavate, black, clear, and colorless at 

 the end. 



Cocoon. — Thin, loose but somewhat tough, covered with bits of earth, etc.. and sptm on the 

 surface of the ground. 



Pupa. — Cremaster conical, cleft at the end, each fork blunt, and bearing three hooked setie. 



Geofjruphiad distribution. — Of the two si^ecies known, one {inter}!)!) is confined to the 

 Appalachian subprovince and the other ranges through the Ajipalachian and the Austroriijaria i 

 subprovinces. 



(J'Jih'masia sciintu Uruce (Biol. Centr. Amer., p. 23."(, pi. 1'5, fig. 1), from Jalai)a and Panama 

 (volcan de Chiriqui), has the sliape of fore wings and the markings of a Dasylophia, and I am 

 quite of the opinion that it is not an (Edemasia (Schizura); the two black round spots near the 

 inner angle are just as in J), anijuina. In fart I regard it as very closely related to I), anyuiua, 

 and hence as a representative species. 



Mr. Neumoegcn has kindly shown me Xi/.sfalea ammonica Staud., from Brazil, and which is a 

 genuine Dasylophia very closely related to our i). nmjuina. If this is so, then the genus ranges 

 through the Mexican ("Sonoran'') subprovince and the Central American region to Brazil. 

 ^. Indiana Grote I am inclined to regard as a Noctuid. ' 



SYNOPSIS OF THE SPECIES. 



Kody anil liasal rogioii of fore wiugs white; a distinct black line along cubital vein D.amjuina 



Body and wings mouse-brown; no black line; basal region of fore wings tawny brown I), interna 



' I copy from Xeuuioe:j;en and Pyar's Kevision the following description of this moth, which I have been 

 unable carefnlly to examine: 



"Xjlxtaltii iiidlcDiu Grote, Papilio, iv, p. 7, 1884. 



"Anterior part of thorax with a dull yellowish patch as in Datana, bordered by black ; the rest gray. Fore wings 

 much elongated; antenna' simple, ciliate, the cilia longer at base, atuftoneach joint a teach side. Primaries cinereous, 

 paler on the disc, distinctly mottled; subbasal line faint, T. a. and t. p. lines close together, straight, parallel, 

 narrow, blackish-brown, equidistant from the indistinct black discal ringlet. On veins 2-3 (viiii-viii), near the 

 base, a black patch; another between veins 3-4 Cvij-v^) just outside t. p. line. Subterminal row of small black 

 dots, two in each interspace, and terminal black shaded spots. Secondaries blackish, i)ale at base. Expanse, 40 mm. 

 Hab. Florida."
