CAENIDES. By Dr. C. Atjrivillius. 
8. Genus: Caenides Holl. 
Antennae long, reaching to the apex of the discal cell of the forewing; the long and thin antennal tip 
is bent down. Vein 11 of the forewing straight and separated from vein 12. Vein 5 of the hindwing distinct. 
Large or medium sized species, generally with large, honey-coloured, or smaller, whitish hyaline spots on the 
forewings. 
Review of the Species. 
I. Forewing above with hyaline spots. 
A. Forewing above with a hyaline spot in area 2. 
a. The hyaline spot in area 2 of the forewing is always nearer at the base than the spot in area 3. 
*. The hyaline spot in area 2 of the forewing is small, broader than long, rarely almost square or 
elongate, whitish or yellowish, not of a pure white. Area 1 b of the forewing without a spot or 
with a small spot which does not touch the spot in 2. 
§. Forewing with a hyaline dot in area 5 *), as well as in 4 *). 
o. Hindwing beneath deep blackish-brown without spots or with some minute white dots 
at most; above uni-coloured or with a transverse row of light dots ($). 
1. Forewing in the discal cell with two oblong, separate hyaline spots, which may also 
be united into one spot. Hindwing beneath at the margin lighter violettish-grey. 
—- (J. Fore wing above between the base of vein 2 and vein 1 with a fine mealy 
(androconial) streak. Hindwing with a large black hairy spot in the centre. 
a. The hyaline spots of the cell of the forewing are separated or only contiguous; 
the hyaline spot 2 is smaller and short, or only extended into a point at vein 1. 
C. dacela. 
b. The hyaline spots of the cell of the forewing are united into one large, rectangular 
spot; the hyaline spot 2 is larger and oblong. C. soritia. 
2. Forewing in the discal cell only with two entirely separate hyaline dots. Hindwing 
beneath as far as the margin brown, only somewhat lighter than in the centre. — 
d' unknown. C. corduba. 
oo. Hindwing beneath with a whitish-yellow ground-colour and blackish-brown spots and 
markings; above behind the centre with a yellow spot in 4 and 5. C. lacida. 
ooo. Hindwing on both sides with a white transverse band. C. malthina. 
§§. Forewing without a hyaline dot in area 5. 
o. Forewing with a hyaline dot in area 4. Hindwing beneath on a grey ground with 
transverse rows of dark spots. C. cylinda. 
oo. Forewing above without a hyaline dot in area 4. 
f. Abdomen above as far as the apex brown. 
1. Hindwing beneath uni-coloured dark brown with or without 1 to 3 small whitish 
dots in 1 c to 3. C. Jcanguensis. 
C. arela. 
2. Hindwing beneath with dark markings on a lighter ground. 
a. Large species; expanse of wings about 66 mm. The hyaline spots of the discal 
cell and of the areas 2 and 3 on the forewing are large and of a bright yellow. 
C. balenge. 
b. Smaller species; expanse of wings about 33 mm. The hyaline spots of the 
discal cell and of the areas 2 and 3 on the forewing are small and whitish. 
Hindwing beneath with a whitish-yellow ground-colour. C. zaremba. 
ff. Abdomen above in the apical half white. O. cretacea d 1 . 
**. The hyaline spot in area 2 of the forewing is large, of a pure white (snow-white). 
o. The hyaline spot in area 2 is only separated by vein 2 from a similar spot in area 1 b; these 
two spots and the likewise white spot in the discal cell together form a coherent or almost 
coherent transverse band. 
§. Hindwing beneath deep blackish-brown, towards the margin somewhat lighter, but 
without a white transverse band. 0. hidarioides. 
*) In the o of C 1 . dacela sometimes of a minute size.
