Math. — Three c? . Very closely related to S. concinna, difteiiiii;' cliielly in the more produced 

 fore \viii<>>!, with the outer angle more oblique, and in its larger size. Head above and tliorax 

 ash-gray, with a slight olive-green tint, behind reddish brown, as in S. coneiiuui. Fore wings much 

 produced toward the apex, tlie outer edge very oblique. The marlcings and shades and discolora- 

 tioii absent, exactly as in *S'. coiicinna, including the costal region, the internal region, and tlie 

 position, shape, and color of the round black discal dot. The internal region or nuirgin of the 

 wing is less black than in (S'. concinna, and more as in (S'. badia, but darker and claret reddish ; the 

 costal region is more distinctly marked with oblique dusky strcalcs than most of my examples of 

 S. concinna, and in this resi)ect the costa is marked more as in badia. The long narrow blackish 

 basal streak on the submedian fold as in (S'. concinna. Hind wings whitish, with a large dusky 

 patch at the internal angle. The underside of both wings pale whitish and marked as in S. 

 concinna. 



Expanse of wing, S 48 mm.; length of body, S IS mm. 



Grote, in his description, compares this moth with ;S'. badia, and does not refer to its close 

 resemblance to »S'. concinna. It differs entirely from S. badia in its round discal dot, that of <S'. badia 

 being long and linear; the thorax and wings are less reddish brown, and the wings are much 

 more elongated toward tlie pointed apex. 



Larra. — Dyar, who regards (Psyche, November, 1891, p. 177) this species as "improperly 

 referred to CEdemasia," and places it " next to S. leptinoidc.s and near Janassa,'' (juotes the following 

 brief description of it from a letter from Dr. Thaxter: 



(Edemasia exiinia resembles Ccclodasi/s leplinoidcs in coloring, but structurally is perhaps more lilie hiijittlatiis 

 (ipomeie). When at rest it is greatly bunched anteriorly, and the furcate prominence on segment i is very long. I 

 should say it ^vas surely a Ccelodasys. 



I copyDyar's description of Stage IV of this species. He states that the "larva superhcially 

 greatly resembles Schizura leptinoides, and was at first mistaken for it." 



^'■Fourth larval staije. — Head high, slightly bilobed, flat before; sordid whiti.sh with a vertical 

 band on each side composed of brown-black dots confluent in streaks, continuous on its posterior 

 edge but breaking up inwardly, the pair connected across the median suture by three more reddish 

 but similar bands, \\hich are indented on the snture and, joining there, border the clypeus. 

 Markings on side of head also reddish, dotted, confusedly, broadly reticulate. Width, 2.3 mm. 

 A long, nutant process on joint 5 preceded by an elevation on joint 4; a slight hump on joint 9 

 and a little larger one on joint 12, bearing the whitish tubercles 1. Sides of joints 2-4 sordid 

 whitish, confusedly reticulate with bands of reddish dots which become blackish stigmatally and 

 dorsally, forming a narrow stigmatal and dorsal band. Body jiale brown, faintly marked with 

 dots of ledbrown or blacki.sh. V-mark distinct, jjale yellow, with no inclosed dot. There is a 

 velvety brown-black subdorsal shade, irregularly touching the region of tubercles 1 and 2, 

 beginning in a narrow line on the side of the process on joint 5, becoming more and more 

 pronounced po.steriorly till it fills in all the space around the V-mark. Joint 12 is again lighter, 

 the brown shade forming a pair of narrow lines on the anterior side of the hump, but obtaining 

 again on joint l.'>. Trace of a lateral line, but broken and diffu.se. A distinct snbstigmatal line. 

 Abdominal feet on joints 7-10 pale, marked with reddish mottlings, the claspers vinous. An 

 oblique brown line runs from base of the born on joint 5 to the anterior side of the foot on joint 7, 

 and another, subventrally, from below the hump on joint 12 to the posterior side of the foot on 

 joint 10 and, continued back subventrally, ends on the anal foot. Setie short, rather dark. 



" Fifth stage. — Much as belbre, but the process on joint 4 is pronounced, leaning backward to 

 touch the horn on joint 5; width of head, 3.5 mm. There is a trace of a hump only on joint 8. 

 V-niark distinct, ^^/hAwA, with centering red lines, but remaining narrow, not diffuse. Dorsal 

 shade mossy olivaceous brown, distinct only on joints 9-13, often quite greenish on joints 10 and
