marcus. 
C. marcus Jord. (8 c). $: Body green, with bluish and ochreous red tints. Eorewing metallic dark 
green, in the centre of the costal area a large irregular creamy yellow spot. Hindwing ochreous red, hut so 
strongly shaded with purplish black that the ground-colour is only distinct at the anal angle and fn a small 
area in the cell; the wing has a blue or green sheen in certain lights. Expanse 42 mm. — Pehas. 
C. gramivora Schaus. Body above light brown, below whitish. Eorewing light brown, partly olivaceous, gramivora. 
in the distal half a large semitransparent area, which does not extend to the margins, is transsected by 
brown veins and anteriorly interrupted by a large brown spot, which extends from the costal margin. Hind¬ 
wing brown, reddish at the base, with reddish brown marginal spots and a large semitransparent submarginal 
area. The wings are much paler beneath. Expanse 64 mm. Sao Paulo, Brazil. — The form of the $ figured 
on pi. 8, parana form. nov. (8 d), is presumably not specifically distinct from gramivora, but is smaller (45 mm), parana. 
the semidiaphanous area of the forewing is centrally not interrupted by a brown spot, the cell of the fore¬ 
wing bears a semitransparent spot, and both wings have a narrow brown marginal band. Castro, Parana,

C. corrupta Schaus. Dark brown, appearing dark metallic green in certain lights, anus orange-red. corrupta. 
At the anal angle of the hindwing a red spot, and between this spot and the centre of the wing creamy 
white scales. On the underside the wings are dusted with reddish scales, which form an indistinct band on 
the forewing and two more distinct ones on the hindwing. Expanse 110 mm. — Colombia. 
C. angusta Druce. S : Body dark brown, legs black-brown. Eorewing dark brown, bluish at the base angusla. 
and distally on the veins; at the apex of the cell a light yellow spot, beyond which there is a narrow 
yellow transverse line running from the costal margin to the hind angle; fringes yellow. Hindwing with the 
ground as on forewing; beyond the centre a transverse row of narrow, yellow, luniform spots from near the 
apex to the anal angle, and near the margin a row of 6 round yellow spots, fringes also yellow. Underside 
lighter brown, on the forewing the yellow band much broader than above, and there is a sublimbal row of 3 
yellow spots; hindwing with two rows of yellow spots. Expanse 165 mm. — Ecuador. 
C. laura Druce, from Chapada in Brazil, has the forewing brown with a broad white band from the laura. 
centre of the costal margin to the hind angle, narrowing posteriorly; near the apex 6 round white spots, 
of which the three anterior ones form a straight row, while the three posterior ones are placed in a slightly 
curved row; fringes brown and white; underside like upper, but the white markings more sharply defined, 
there being moreover a row of large orange-yellow marginal spots. Hindwing brown, with a row of large, 
pure white spots from the costal margin almost to the anal angle, and large orange-yellow marginal spots; 
underside like upper, but lighter; fringes brown. Body and legs dark brown, anus orange. Expanse about 
102 mm. 
C. dolopia Druce. Abdomen black, brown at the base like the rest of the body; antenna black with dolopia. 
light brown apex. Forewing dark brown, with large greyish brown spot at the apex of the cell, beyond the latter 
a transverse row of greyish brown spots edged with black, at the hindmargin two black luniform spots. Hind¬ 
wing black, with a row of brownish white spots from near the anal angle almost to the apex; fringes brown¬ 
ish white. Underside of both wings light brown, all the spots much more distinct and edged with black. 
Expanse 197 mm. — Ecuador. 
C. delecta Schaus. S'. Thorax whitish grey, venter orange-yellow, the body otherwise brown. Forewing delecta. 
reddish brown, with large (dark brown?) spot at the apex of the cell, a dark brown line from the centre 
of the hind margin to the apex, a subapical white spot, and dark brown fringes. Hindwing reddish, black 
posteriorly at the base, distally with 5—6 darker spots and a brown marginal band from the anal angle to 
vein 6. Expanse 49 mm. In the $ the forewing yellow, partly darker, with two white subapical spots, basal 
area reddish brown. Hindwing reddish yellow, with orange veins, and smaller spots. Expanse 57 mm. — 
Costa Rica, Mexico. 
C. wagneri Buchecker, from Colombia, is unfortunately not known to me, nor have I seen a descrip- wagneri. 
tion. 
The two following species form a group by themselves, being characterised, inter alia, by the small 
size and the magnificent colouring (at least in erycina); they are both unknown to me in nature. 
C. erycina Westw. (= hyperbius Westw. in tab.), from Ecuador, is (together with the next species) an erycina. 
isolated form recalling Erycinidae, from which it has derived its name. The size (expanse 40 mm) is quite excep¬ 
tionally small among the Castniae ; the forewing is blue at the base for a distance of 5 mm, then follows a 
red transverse band, slightly narrower, the rest of the wing being glittering green; the ground appears to be 
dark everywhere. Hindwing blue-black from the base to two-thirds, glossy silvery green in the distal area, 
and blood-red at the costal margin. 
C. pelopia Druce, from the interior of Colombia, is said to be nearly allied to erycina, but is much pelopia. 
more black, the underside of both wings is grey-green, and the venter light red, while in erycina it bears 
green bands.
