Moth, — Three S . Very closely related to coneinna, diflering cliiedy iu the more produced 
fore ■wings, with the outer angle more oblique, and iu its larger size. Head above and thorax 
ash-gray, with a slight olive-green tint, behind reddish brown, as in S, concinna. Fore ivings much 
produced toward the apex, the outer edge very oblique. The markings and shades and discolora- 
tion absent, exactly as in 8. concinna^ including the costal region, the internal region, and the 
position, shape, and color of the round black discal dot. The internal region or margin of the 
wing is less black than iu 8, concinna^ and more as in 8, badia^ but darker and claret reddish; the 
costal region is more distinctly marked with oblique dusky streaks than most of my examples of 
8, concinna^ and iu this respect the costa is marked more as in bndla. The long narrow blackish 
basal streak on the subraedian fold as in 8, coneinna. Hind wings whitish, with a large dusky 
patch at the internal angle. The underside of both wings pale whitish and marked as in 8, 
C07icin7ia. 
Expanse of wing, 3 48 mm.; length of body, ^ 18 mm. 
Grote, iu his description, compares this moth with 8, badia, and does not refer to its close 
resemblance to 8, coiiciniia. It differs entirely from 8. badia in its round discal dot, that of 8, badia 
being long and linear; the thorax and wings are less reddish brown, and the wings are much 
more elongated toward the pointed apex. 
Larva. — Dyar, who regards (Psyche, November, 1891, p. 177) this species as “improperly 
referred to (Edemasia,” and places it “ next to 8. Icptmoides and near quotes tlie following 
brief description of it from a letter from Dr. Thaxter: 
(Edemasia eximia resembles Ccclodasys lepiinoidcs iu coloring, but structurally is perhaps more like hiyattatus 
{tpomeui). When at rest it is greatly bunched anteriorly, and theiurcate proinineuce on segment 4 is very long. I 
should say it was surely a Ccelodasys. 
[ copy Dyar’s description of Stage IV of this species. He states that the “larva superficially 
greatly resembles Schizivra leptinoiden.^ and was at first mistaken for it.” 
^^Fouvth larval stage. — Head high, slightly bilobed, flat before; sordid whitish with a vertical 
band on each side composed of brown-black dots confluent iu streaks, coutiiuious on its posterior 
edge but breaking up inwardly, the pair connected across the median suture by three more reddish 
but similar bauds, which are indented on the suture aud, joining there, border the clypeus. 
Markings on side- of head also reddish, dotted, confusedly, broadly reticulate. AA^idth, 2.3 mm. 
A long, nutaut process on joint o 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 bauds of reddish dots which become blackish stigmatally and 
dorsally, forming a narrow stigmatal and dorsal band. Body pale brown, faintly marked with 
dots of red-brown or blackish. V-mark distinct, pale yellow, with no inclosed dot. There is a 
velvety brown-black subdorsal shade, iiTegularly 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 posteriorly 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 13. Trace of a lateral line, but broken and diffuse. A distinct substigniatal line. 
Abdominal feet on joints 7-10 pale, marked with reddish mottlings, the claspers vinous. An 
oblique brown line runs from base of the horn on joint 5 to the anterior side of the foot on joint 7, 
and another, subventrally, from bedow the hump on joint 12 to the posterior side of the foot on 
joint 10 and, continued back subventrally, ends on the anal foot. Sebe short, rather dark. 
“ Fifth stage. — Much as before, but the proc.ess 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-mark distinct, pinkish, 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 aud
