exterior edge of the areole, 9 and 10 on a short stalk from its apex, 11 from its centre. $ not known. Costa 
Rica. 
C. abnoba Schs. (167 g). Dark violettish grey with white scales in the submedian area and before the 
marginal spot which is yellow, extending from the costal margin to the anal angle, covered with dark brown 
except the apical area and in several other smaller parts, traversed by a large curved brown strigiform spot 
which is strangulated below the middle; a round white spot at the cell-end with a black dot in it, and a qua¬ 
drangular dark submedian spot in the basal third. Hindwing without the blue reflection. 7 and 8 of forewing 
separated, arising from the areole, 9 and 10 together from its apex, 11 from the basal third. Only the $ is known. 
From Brazil. 
C. ardosiata Dejn. (167 g). Forewing dark violettish grey, lighter in the $, coarsely striated darker; a 
diminutive white brightening before the marginal spot, the spot itself dull yellow, strewn with brown with an 
irregular brown marking at the interior edge and a small isolated spot beside it; it extends from the costal margin 
to the anal angle. Hindwing dark. Veins 7 and 8 of forewing separately from the areole, 9 and 10 on a short 
stalk in one specimen, arising together in another one. French Guiana. 
C. orima Drc. (= stoica Dgn.) (169 i). Forewing dark grey, finely striated blackish, an extensive white 
area before the large straw-coloured marginal spot; the spot itself is black at the costal margin and anal angle 
and contains 2 large roundish black spots slightly projecting outwards, the lower one extending to the margin. 
Veins 7 and 8 of forewing on a long stalk from the areole, 9 and 10 together from its apex, and 11 from the 
basal third; one specimen shows the stalk of 7 and 8 shorter. Brazil, Bolivia, Peru. 
C. magna Schs. (181 f). Dark grey, intensely speckled whitish, with an extensive light, though not 
contrasting area before the marginal spot; the latter is dull ochreous, with an angled brown marking inside 
and an ochreous crescent before it, from which streaks proceed above and below, the upper one angular, the 
lower one extending to the margin; costal margin, anal angle and fringe brown. Hindwing dark. Veins 7 and 8 
of forewing distantly separated from the areole, 9 and 10 on a short stalk from its apex, 11 from the centre. 
Only l $ known from British Guiana. 
C. magnifica Stkr. (= norax Drc.) (181 a) is very similar to magna , but it is much smaller, the white 
areas on the forewing clear and distinct, especially that before the marginal spot; the latter is somewhat lighter 
yellow than in magna, the upper end of the dark marking not angled and the two horns of the crescent often 
reach the margin. Veins 7 and 8 of the forewing arise on a long stalk from the areole, 9 and 10 likewise stalked, 
but the stalk only half as long, 11 from the centre of the areole. Florida, Mexico, Guatemala. The larva is said 
to bore in the trunks of oak and hickory. 
C. omaia Schs. (167 h). Fore wing long and narrow, pointed. Forewing dark red-brown with a small 
subbasal black transverse streak in the middle; the lighter parts yellowish like the marginal spot, especially 
a round spot at the cell-end and before the marginal spot; the latter contains an irregular brown basal line, 
streaks at the costal margin and anal angle and two large irregular central spots, the lower one extending to 
the margin. Veins 7 and 8 of forewing arise separated and parallel, 9 and 10 together from the apex of the 
areole, 11 from its centre. Only the <$ is known. From British Guiana. 
C. arpi Schs. (= nigripuncta Dgn.) (167 h). Forewing narrow and pointed in the <$, less in the §. Light 
grey, speckled white, with a large subbasal quadrangular black spot. Marginal area dull brownish yellow and 
greyish, the fringe dark, but not so contrasting as usual, the costal-marginal and anal-angular spots and the 
central marking dark velvety brown, variable, mostly quadrangularly lobate, the lower angle extending to the 
margin. 7 and 8 of forewing separated, 9 and 10 together. From Guatemala, Costa Rica, Panama, Colombia 
and Guiana. 
C. oletta sp. n. (167 h). Forewing of $ narrow and pointed, dark grey with black transverse striae and 
lines,* a whitish quadrangular spot submedianly in the discal area, and a slight brightening before the marginal 
spot; the striae form a straight black line in the basal third, and a more irregular one before the marginal spot; 
the spot itself is light yellow, the fringe dotted brown, the costal -marginal and anal streaks brown, in the middle 
with a brown strigiform spot which despatches below a strong arm to the margin. Hindwing dark brown. Veins 
7 and 8 of forewing arise separately and parallel from the areole, 9 and 10 together from its apex, 11 before its 
centre. Medina (Eastern Colombia), 500 m; type in the U. S. National Museum (A. H. Fassl leg., Coll. Dognin). 
C. gaudeator Schs. (182 g) is very similar to magna (181 f), the $ of which has bipectinated antennae 
(<d unknown), while the antennae of gaudeator-^ ($ unknown) are singly pectinated outside, though there are 
very distinct short double pectinations at the base. The markings are different: while magna shows the brown
