Puate VII. 
Calinaga Sudassana, sp.n. 
?. Wings: Upper side smoky grey, subhyaline, merging into 
black towards the outer margin beyond the disco-cellular ner- 
vules; primaries elongate-triangular ; costa somewhat arched, with 
whitish grey powdering of scales between this and the subcostal 
nervules; posterior margin slightly emarginate, having a double 
series of submarginal white spots in the following arrangement :— 
Two in the centre of the space between the lowest subcostal and 
the upper discoidal nervules, two a little wider apart between the 
two discoidal nervules, two smaller and closer together between the 
lower discoidal and the first median nervule. Between this latter 
and the second median nervule the outer spot all but touches the 
posterior margin; the inner is central, large, and whitish; there is 
a large grey dash between this and the median nervure, and there are 
similar markings between the second and third median nervules, 
Between this last and the submedian nervure the spots and dashes 
get more conspicuous and almost confluent, merging into the space 
between the submedian nervure and the anal angle in a long sweep 
of almost unbroken light grey, nearly corresponding in size to the 
discoidal cell, which is of a similar colour, with slight central 
clouding of darker hue; the median nervure is very distinctly 
clothed with black scales, as in C. Buddha (Moore), and the ner- 
vules in hke manner also are very marked. The secondaries have 
also a double row of submarginal spots; the discoidal cell and 
abdominal margin pale hyaline grey, the latter tinged very con- 
spicuously and prominently with bright ochraceous yellow; the 
median nervure notably clothed with dark black scales, as also the 
median nervule. Under side as in the upper, but less clearly 
marked, the black giving way to a suffused brown, and the clear 
ochre-yellow at the abdominal angle of the secondaries is barely 
noticeable. Thorax reddish crimson, with long soft hairs. Abdo- 
men black, with scattered black hairs. In the two specimens I
