Beneath, the light median bands of both wings appear alike in colour, being of the same shade as that on the 
upperside of the hindwing, the dark areas are reddish brown, only being black in the anal angle of the hindwing 
and the posterior half of the postmedian band of the forewing. 
I;. Forewing blackish with two greyish yellow, irregular curved transverse bands directed slightly obliquely towards 
the costal margin. Hindwing black or blackish with red Sublimbal band bearing black spots. Large insect. 
C. pylades Stoll (5 c), occurring in Cayenne, Brazil, etc., is on the whole darker than our figure indicates, 
and the greenish sheen seems usually to be less distinct. — The larva lives in bananas. 
M. Both wings blackish with light markings consisting of numerous spots or narrow bands, recalling the pattern 
of Neptis. 
C. galinthias Hpffr. (6 a), from Brazil, has the basal area of the hindwing below whitish, and the ground¬ 
colour above is usually darker, more blackish than i then case is our figure. 
C. strigata Wkr. (- - discoidalis Buchecker) (6 b), from Brazil, sometimes has the whitish band originating 
in the middle of the costa separated into spots in the distal half, or, one might say, it is absent there, while 
the white spots in the apical half of the wing are larger and more numerous than in our figure of godarti Men. 
— The larva is said to live in orchid-roots. 
C. decussata Godt. (6 a). Brazil. A large $-form (expanse 91 mm.) differs in that the anal angle of the 
hindwing bears a reddish yellow spot and that the larger basal half of the underside of the hindwing is pure white. 
I name this form fulvipyga form. nov. 
X. Wing white, with black marginal marking. 
C. cronis Or. (6a) is distinguished from the other Pierid-like true Castnia, viz: 
C. cronida H.-Schdff. (6 c) very easily by the differences shown in the figures. Both occurr in Guiana. 
0. Small brownish insects, with two narrow whitish transverse bands, partly divided into branches and directed almost 
vertically towards the costal margin, with light innermarginal band, and some of them with a central longitudinal one. Hind- 
wing black, with red and white markings. 
C. huebneri Latr. (= sternbergi Roll., castnioides Buchecker) (6 b). Brazil. In true lmebneri the two 
light bands of the forewing and the light median row of the hindwing white (purer white than in our figure), 
and the fringes usually pure white in the apical half. — In fa. impura form. nov. these markings are dirty 
ochreous and the fringes uniformly greyish brown, as well as the ground-colour of the entire wings above 
somewhat darker. — If in addition the row of light spots in the dark area on the hindwing is entirely or 
almost entirely obsolete, we have the form indecora form. nov. 
C. uruguayana Burm. (6 b). Characterised inter alia by the light longitudinal stripes on the thorax dor- 
sally, varies considerably in the markings of the hindwing, and has lighter and darker transverse bands on the 
back of the abdomen, which are not visible in our figure. — A form of which a $ is before me is distinguish¬ 
ed by the proximal red transverse band of the hindwing not being connected with the median one, while 
the latter only once touches the distal one, moreover there are no isolated light spots between the bands of the 
forewing. To this form, the exact locality of which is unfortunately not known to me, I give the name separa¬ 
tula form. nov. 
P. Ground-colour of wings reddish, brown or orange, hindwing with narrow black marginal band having light 
spots, forewing with one or more small subapical vitreous spots (with the exception of bogota). 
C. therapon Roll. (= therapion B.sd., paradoxa H.-Schdff.) (7 a), from Brazil, has the same ground- 
colour beneath as on the hindwing above; the black marginal band on the underside of the latter has two 
rows of light dots below. The larva lives in Oncidium crispum (cf. Snellen, Tijdschr. v. Ent. 38, p. 9) and 
Catasetum sp. (cf. Klug in Abh. Ak. Wiss. Berlin, p. 245 to 257, 1848). 
C. rutila Fldr. (7 a), also from Brazil, has no black marginal band on the underside of the hindwing, but 
a sublimbal row of brown spots. 
C. bogota Strand. $. Forewing reddish brown, darker at the cliscocellular, the fringes white, at least 
posteriorly, inner margin narrowly black. Beneath orange-yellow in the middle and in the dorsal region, more 
reddish basally; a band about 2 mm broad at the costal margin becomes gradually broader from the middle 
to the margin, attains a width of 7 mm. at the apex of the wing and then becomes gradually narrower poste¬ 
riorly reaching to vein 2, from where it continues to the inner margin as a black band thrice deeply indented 
on its inner side. In the marginal area veins 3 to 5 are also dusted with black. Discocellular spot deep black, 
in an oblique position and 2 x 1.2 mm. in size. Hindwing above and below orange with deep black marginal 
band which is 5 mm. broad, but becomes somewhat narrower anteriorly and is minutely dentate on its inner side; 
above in each of cellules 1 to 4 it encloses a small spot with a bluish sheen; similar but still larger spots 
are also present beneath, where the band is truncate between veins 5 and 6. Body above blackish, below 
orange as are also the legs. Expanse 42, length of wing 25 mm. — Bogota (Type in coll. W. Niepelt).
