COEQUOSA; CLANIS. By Dr. A. Seitz. 
australasiae. M. australasiae Don. (= banksiae Btlr.) (66 cl). Forewing earth-coloured brown, mixed with grey and 
loam-colour. From the costa a large dark triangular spot extends, its apex reaching to the submedian; a similar 
quadrangular spot is opposite to it on the inner margin. Hindwing golden yellow; in the anal portion and at 
the margin dark brown with grey embedments. More to the south of the Australian continent, in South Queens¬ 
land and New South Wales. Not common. 
19. Genus : Coequosa Wkr. 
Separated from the preceding genus by the hind tibiae having but 1 pair of spurs, whilst in Metamimas 
there are 2. The imagines are still larger than Metamimas. 
triangularis. C. triangularis Don. (— castaneus Perry) (66 cl). Larger, stouter than M. australasiae, with rounder 
forewings, the margin hardly projecting below the apex. Hindwing relatively larger. Forewing darker brown, 
the triangular spot on the costa deep umber-brown; on the inner margin there is not such a spot. Hindwing 
dark brown, only at the base and costa orange. — Larva extremely large and stout, green, shagreened, with 
7 lateral oblique stripes. Head small and very pointed, frons prolonged, so that the larva seems to end in front 
in a somewhat curved cone. On the hornless posterior end the larva shows above the claspers two black, pearl- 
or button-shaped lustrous ocelli. On being disturbed it peculiarly moves its anterior part in a swinging or 
striking way, so that one is inclined to consider the hind part with the sham eyes to be the head of the insect. 
On Banksia, Acia, and Persoonia. Eastern Australia, from Queensland and New South Wales, in many 
districts not rare. 
20. Genus: Clanis Hbn. 
The seven species of this genus (for further particulars cf. Vol. II, p. 239) all occur in the Indian Region; 
five are confined to it, whereas two, owing to their chief distribution, are palaearctic. Large insects partly 
of a very squat structure, with a short proboscis which, however, is able to take up liquid, and long wings. 
phalaris. C„ plialarls Cr. (= cervina Wkr., pagana F., nicobarensis Schz.) (66 a). Shape most similar to that of 
Oxyambulyx to which this genus is allied. Apex pointedly produced, distal margin of forewing rectilinear. 
Colouring earth-brown, with a more or less reddish tint; forewing with 5 or 6 distinct, darker, parallel transverse 
stripes. Thorax with a dark median line which, however, is no more distinct on the abdomen. —- Larva green, 
granulated, oblique stripes white. -— North India to the south as far as Ceylon and the Andamans. 
stenosema. C. stenosema B. du J. (66 c as stenosoma) is much larger than phalaris, with broader hindwings. In the 
forewing a light triangular spot rests with its broad base on the costa, the hindwing is deep blackish-brown 
excepting the margins. From Nias. 
brooksi. C. brooksi Bothsch. is still larger than stenosema (the male of brooksi as large as stenosema -§). The light 
area extending from the costa inwards is much longer than in the otherwise quite similar bilineata (Y ol. II, 
pi. 37 c), but not quite so long as in stenosema (66 c), not reaching to the 2nd line; 1st and 2nd lines much 
straighter, not angular nor notched. In the hindwing the black colour does not reach so far to the apex. Sumatra. 
undulosa. C. undulosa Mr. (= bilineata Leech nec Wkr., gigantea Bothsch.) (Vol. II, pi. 37 b). Shape and wings 
similar to brooksi, but the forewing without the costal triangle and crossed by numerous chains of crescents. 
pallescens. Hindwing covered with blackish save the margins. - pallescens Melt is a pale form in which the transverse 
roseata markings are much or altogether reduced. roseata Melt, from South China, shows the antennae and thorax 
acuta, tinged with pink, with less black in the hindwing. - - On the contrary, acuta Milt shows the black colour on 
the hindwing extended to the margin; the transverse lines of the forewing are distinct, the longitudinal stripe 
from the costal margin to the termen is light brown; Kwang-tung. — Larva green or yellow with reddish mouth 
and pectoral feet, the lateral oblique stripes quite dull and thin, the horn in the adult insect is merely a stump 
1 mm long. On the Papilionacea Lespedeza viatorum. — From the banks of the Yangtsekiang R. to the east 
as far as Formosa, to the south as far as North India and Assam, local though in some places in great numbers. 
For further particulars cf. Vol. II, p. 239. 
deucalion. C. deucalion Wkr. But very few specimens are known, from North-West India. Quite similar to 
undulosa and perhaps only a form of it (the male genitals have not shown any differences). It chiefly differs in 
the shorter margin of the forewing, a smaller black spot on the hinclwing, and in the costal area of the forewing 
not being lighter; the spurs of the hind tibiae are also shorter, and the 1st foot-joint on the hind leg is shorter, too.
