CELAENORRHINUS. By Dr. C. Aurivillius. 
11. Genus: Celaeiiorrliinus Hbn. 
This wide-spread genus containing many species is also represented by many species in the Ethiopical 
region. They all exhibit above a black or dark brown ground-colour with numerous, often large, yellow, or 
rarely white spots of the forewing and often also of the hindwing. The forewing often shows a basal spot in 
1 b and sometimes also in 11 and 12, and discal spots in 1 b to 8, 11, 12, and in the discal cell; the spot in 
the cell consists of two large, invariably united spots. Hindwing above with one or several distinctly defined 
yellow spots or rarely without such spots, but as in many of the species of Sarangesa, with transverse rows 
of large dark spots distinctly contrasting with the somewhat lighter ground. 
Forewing: vein 2 before the centre of the cell, 3 about just as distant from 4 as 4 is from 5, 5 in 
the centre between 4 and 6, 11 separate. Hindwing: vein 2 far behind the centre of the cell, 3 almost from 
the posterior angle, 5 distinct. Margin of hindwing between the veins 1 b and 3 almost straight or somewhat 
emarginated. Antennal club almost in the centre bent down with a long and sharp point. Terminal joint of 
palpus short coniform or knob-shaped. — <$. Hind tibiae with a hair-pencil; first tarsal joint with appressed 
scales, without hairs. 
Review of the Species. 
I. The two discal spots of area 1 b of the forewing above are separated, touch each other only in one place, 
or they are united into a narrow transverse spot the anterior part of which is square or only slightly 
longer than broad. 
A. All the spots of the forewing yellow, orange or honey-coloured, more or less transparent. 
a. Hindwing above densely covered with rusty-brown hairs, with black veins, a black costal margin 
and black marginal band. 
*. Hindwing above without black spots in the rusty brown part. C. rutilans. 
**. Hindwing above with some large black spots in the rusty-brown part. 
C. rutilans v. nigropunctatus. 
(3. Hindwing above blackish-brown without rusty-brown hairs, 
f. Hindwing above with one or several yellow spots. 
*. Hindwing above at or near the margin with bright yellow spots or with a yellow marginal 
area. Forewing almost invariably above with 2 or 3 basal spots (in lb, 11 [and 12]). 
§. Hindwing with a large yellow marginal area covering at least the greatest part of the 
areas 2 to 5. 
1. Forewing in 4 and 5 with yellow discal spots near the margin, which are united into 
a small transverse streak. C. galenus. 
2. Forewing without discal spots in the areas 4 and 5. C. homeyeri. 
§§. Hinclwing in the areas 4 and 5 as far as the margin yellow, uni-coloured or with 1 or 2 
black spots; the spot in 4 and 5 is often united with smaller yellow spots of the areas 
3 and 6. Forewing generally with discal dots in 4 and 5. 
1. The yellow spot of the areas 4 and 5 of the hindwing is not spotted, entirely filling 
up the two areas. C. intermixtus. 
2. The yellow spot of the areas 4 and 5 of the hindwing encloses two black spots some¬ 
times dividing the yellow spot (almost) into two halves, an interior and an exterior 
half. C. biseriatus. 
**. Hindwing above without yellow spots at the margin, only in the centre at the end of the 
discal cell with a distinctly prominent yellow spot. C. mokeezi. 
ft- Hindwing above without any yellow spots, on the somewhat lighter ground with transverse 
rows of dark spots. C. modestus. 
C. bettoni. 
B. All the spots of the forewing white and, transparent. 
a. Hindwing just like in C. mokeezi (76 b) with a yellow central spot. C. humbloti. 
p. Hindwing without yellow spots, blackish-giey with transverse rows of black spots. C. proximus. 
II. The discal spots of the area 1 b of the forewing above are always united into one spot; the anterior division 
of this spot is elongate, more than twice as long as it is broad. 
A. The spots of the forewing are transparent, white. Hindwing above black without markings. 
C. macrostictus. 
B. All the spots of the forewing yellow or honey-coloured, more or less transparent. 
a. The discal spot in 1 b of the forewing is only moderately long (generally only half the length of the 
spot in 2) and its posterior division much smaller than the anterior, square or streak-shaped.
