though these are never so ample as in spreta. — In ah. stenospila Warr. they show their minimum ot development, sienospila. 
the yellow outer band of the forewing being only about 3 mm wide. Name-typical perithea is common in 
the South Moluccas. — keiensis Prout is a large, deeply-coloured form from the Key Islands and perhaps heh-nsU. 
Manovolka, with the yellow ground-colour of the forewing extending along the hindmargin nearly to the 
anal angle and often showing also in streaks on the black costal margin. "Distal border of hindwing broader 
than in spreta. 
C. exacta Warr. In this and the following 7 species, many of which resemble the preceding group exada. 
in the scheme of markings, the 3rd joint of the palpus is short and the 2nd tarsal joint of the <$ is as long as. 
or longer than, the undilated terminal part of the 1st joint, only in prodroma very slightly shorter, exacta is a 
very distinct species in the deep colouring and in the thin grey line which on both wings traverses the black 
marginal band. Solomon Islands. 
C. prodroma Meyr. (= remutata Prout). Oblique black band of forewing incomplete, terminating at pndronm. 
the fold or at the 2nd submedian vein. British New Guinea. 
C. commutata Walk. (3 i). Oblique black band broader than in prodroma, unique in being acutely commutaia. 
angulated at fold, thence running obliquely inward to hindmargin. Only known from the Aru Islands. 
C. angustisignata Prout. Similar to prodroma, oblique black band narrower, slightly curved: distal anguslisig- 
border of hindwing, also of forewing posteriorly, greatly narrowed, the latter consequently angulated about 
the 2nd radial. Sudest Island. 
C. probola Prout. Also similar to prodroma but with the oblique band continued to the anal angle, probola. 
joining the black border, and sometimes with some yellow scaling in the paler part of the apical area of the 
forewing, thus superficially recalling a small mutata, which is in a different structure-group. Tip of palpus 
with the black more extended than in prodroma, hindtarsus of <$ predominantly blackish (in prodroma yellow). 
Humboldt Bay, Dutch New Guinea. 
C. pallidicolor is geographically variable, or possibly there are two or three species mixed. $ antenna 
with less strong sex-scales in proximal part than in probola. hindtibial process and hindtarsus deeper black, the 
processes both of the tibia and tarsus very strongly developed. Oblique band of forewing always broader than 
in probola, reaching the base of the 2nd median vein. - pallidicolor Warr., from Waigeu and Dutch New Guinea, pallidicolor. 
has the oblique band well defined proximally, the proximal area (excepting the costal margin) being entirely 
yellow. — hirtipes Warr., from the Upper Aroa River, British New Guinea, has the borders less deep black but liirtipes. 
rather broader, the yellow subapical band of the forewing consequently somewhat less broad, the proximal 
area of the forewing usually, though not invariably, more or less strongly suffused with grey. • — griseofusa Warr., griseofusa. 
from Eergusson and Normanby Islands and the coast districts of British New Guinea, has the yellow subapical 
band narrower still, the grey proximal suffusions always strongly developed, sometimes also extending to the 
abdominal region -of the hindwing. 
C. aurata Warr. (5 a) differs from all the other species in having the black markings reduced to lines aurata. 
— on the forewing one along the base of the costa and two oblique ones from nearly one-half and nearly three- 
fourth of the costal margin, on the hinclwing a single submarginal line; none of these lines reach the hindmargin. 
Some specimens further show a minute black tip to the fore wing. Confined to R-ossel Island. 
C. mutatipes Prout (5 a). Smaller than pallidicolor, rather more deeply coloured, the oblique band nudatipes. 
always broad, sometimes extremely broad. Hindtibia of $ yellow, tarsal process mixed with yellow; first 
tarsal joint- shorter than in the allied species, not so long as the tibial process. Upper Aroa River, British New 
Guinea. 
C, latiflava is still smaller, rather less narrow-winged and differs structurally in that the $ hindtibia, 
though dilated, lacks the terminal process and the first tarsal joint lacks the triangular swelling. — latiflava tatiflava. 
Warr., from Dutch New Guinea, has the black border of the hindwing rather narrower than in the following 
race, tapering almost to a point at the anal angle; the black oblique band of the forewing is also on an average 
narrower, but is variable. Face predominantly yellow. — nigriceps Warr., from British New Guinea, has nigriceps. 
the face black-grey. — ab. restricta Warr. has the oblique band of the forewing greatly widened, the hindmargin resirida. 
of both wings broadly suffused with black; thus on the forewing only a very small yellow basal patch remains. 
C. recurvata Warr. (= flavotogata Pagenst.) (3 i) resembles latiflava in the structure of the $ hind- recurvaia. 
leg, but is very different in the black thorax, black base of hindwing and very broad black borders. Very 
characteristic is the extension of the yellow outer band along the costal margin nearly or quite to the base. 
North Moluccas. — reversa Warr. (3 i), from Obi, differs in the blacker abdomen and in not having the yellow reversa. 
band extended proximally along the costal margin.
