C. multifaria Wkr. (26 g) differs from the preceding by the entirely black forewings with a snow-white 
costal margin and fringes; the latter are blackish between the lower median and upper radial veins, on both 
wings. Head, shoulders, and proximal margin of the shoulder-covers scarlet, in f. luteoscapus Neum. and Dyar 
orange-yellow. California. 
C. rubroscapus Men. (= walsinghami Hy. Edw.) (26 g) greatly resembles the preceding, but it has 
an entirely black costal margin and fringes; the latter are whitish only at the apices of the wings. — In 
ochroscapus Grote & Rob. (= corvina Bsd.) the red parts of the anterior body are orange-yellow. Western 
United States. 
C. virginica Charp. (= latreilliana By.) (26 g) is one of the largest species with dull blackish-brovm 
forewings and somewhat darker, faintly lustrous blue hindwings; at the base of the forewing there is a metallic 
blue spot. Palpal base, vertex, neck, shoulders, and base of shoulder-covers orange; thorax and abdomen with 
a greenish-blue lustre. From the United States and Canada. •— The larva being very densely haired black 
and white, on the dorsum yellow, shows white subdorsal and undulate lateral "stripes; on the dorsum nine double 
hair-tufts. It lives on grasses. 
C. fosteri Rothsch. has an orange-yellow head, basal half of the collar, and inner side of the shoulder- 
covers. Thorax and abdomen are sooty blackish-brown, beneath sooty black. Forewings dark wooden brown, 
hindwings sooty black, both with white fringes. Length of forewings: 21 mm. Paraguay. 
C„ conchyliata spec. nov. (26 f). The body is blackish-brown, abdomen and hips with a blue lustre; 
the two first palpal joints, throat, hindhead and neck are carmine-rosy. The forewings are unicolorously dark 
brown, the hindwings in the marginal third with an irregular proximal bordering inclusive of the fringes purple 
red, the rest bluish-black. Described according to a $ from Peru (Vilcanoa). Type in the Coll. Draudt. Accor¬ 
ding to the description, Propyria nigriruja Rothsch., being unknown to me, must look like it. 
C. affinis Druce. Anterior body olive-blackish with a bluish shine, the first 2 palpal joints, the neck and 
throat are orange, abdomen black with a blue lustre. Forewings olive black, fringes at the apex white, so is 
a triangular spot at the proximal angle. Hindwings black with a metallic blue lustre, ends of' fringes white. 
Expanse of wings: 34 mm. Guatemala. 
C. clavia Druce (26 g). The dark brown forewings exhibit a broad, yellowish-white longitudinal stripe 
from the base to the margin, the white hindwings a broad, brown border, being in the middle expanded like 
a spot, and proximal margin. Body metallic bluish-green with long black hair. Ecuador. 
C. albolineata Druce (= projecta Dogn.) looks like clavia (26 g). The body is black, on the thorax 
and abdomen with an intense metallic blue lustre. Forewings black; a w r hite line extends from the base through 
the middle of the cell below the apex almost to the border; above its end there is a small, round, white spot; 
base and proximal margin are striped metallic blue. Hindwings black with a broad, white costal band not 
reaching the apex. Expanse of wings: 48 mm. North Peru. 
154. Genus: Dahana Grote. 
Siphon well-developed; palpi rather long porrect, the terminal joint turned somewhat downward. 
Antennae doubly combed. The $ shows at the base of the abdomen lateral tubercles with an aperture beneath. 
Wings long and narrow, both above the proximal angle somewhat concavely indented. The veins similar as 
in Ctenucha, but the upper radial vein, on the forewing, comes from the upper cell-angle; on the hindwing, 
both the lower radial veins come from the lower cell-angle, the subcostal vein at some distance before the upper 
cell-angle. 
D. atripennis Grote (26 g). Head and thorax blackish-brown with a metallic blue lustre. Palpal base, 
vertex, base of shoulder-covers, and upperside of the abdomen orange, the latter being spotted black beneath, 
laterally metallic blue. Forewings blackish-brown, dusted rusty brown, at the proximal angle an ochreous- 
yellow cuneiform spot. Hindwings black with a metallic blue lustre. Expanse of wings: 42 mm. Florida. 
D. cubana Schaus. Head dark blue, beneath and laterally red, like the palpal base. Thorax black, 
shoulder-covers striped blue. Abdomen blue, the 2 last rings carmine, extending above almost to the base. 
Forewing black, at the base striped metallic blue. Hindwing metallic blue, apex and distal margin black. Ex¬ 
panse of wings: 28 mm. Cuba. 
155. Genus: Epectaptera Hmps. 
Palpi porrect, just projecting beyond the forehead. Fore wing with a very much extended apex and a 
very oblique, somewhat concave distal margin, the veins being the usual ones; on the hindwing, the lower 
median vein rises far before the lower cell-angle, out of which the upper median vein and the lower radial 
proceed the middle radial vein rising from above the upper cell-angle, the uppermost radial vein and the 
subcostal from the upper cell-angle.
