ajiical patch ; there is uo pale line before R' and uo pale costal area. The blatk 

 patch oil the hiiidwing is restricted, louger at SM- than at IV, and appears 

 sinuate between M' and SM- ; there are tawny brown scales between this patch 

 and the apex of the wing. The individual came from N. India, and has uo more 

 precise localitj-. A <^ in the Oxford Museum from E. India (Hnttou) agrees well 

 with this ?. Another cJ in the British Museum, from the Leech collection, obtained 

 by Captain Young at Knlu, belongs doubtless to this species. It is very pale, as pale 

 as the palest pludaris. It agrees with undulosa in the midtibiae not being white 

 above like the hmdtibia and in the presence of a black streak on the underside 

 of the forewing. The specimen is comparatively small, the forewing measuring 

 only 47 mm. in length ; the lines of the forewing are scarcely traceable, the black 

 patch of the hindwing is still more restricted than iu the type of daiicalion, the 

 black scaling not extending beyond the end of the cell between R^ and SG-, while 

 the ai'ea between cell and apex of wing is shaded with pale tawny. The two males 

 difter structurally from iinchdosa in the following points : the hindtibia is as long 

 as the first tarsal segment, and this barely longer than segments 2 to o together ; 

 the terminal ]iair of spurs is very unequal, shorter than in undulosa, the long one 

 only half the leugth of the first tarsal segment. The genital armature is as in 

 ioidulosa, but the lobes of the tenth tergite are somewhat slenderer, and the steniite 

 is rounded. 



The shorter distal margin of the forewing, the reduced, sinuate, black patch 

 of the hindwing, the absence from the forewing of a pale costal area and of a 

 white line before R-", the shorter spurs of the hindtibia, and shorter first hindtarsal 

 segment, are the principal characters by which this species can be distinguished 

 from undulosa. 



The larva mentioned by Forsayeth, I.e., may belong to this or some other 

 species.

(J ?. In colour and pattern and the proportions of the tibiae, spurs and tarsi 

 close to the much larger CI. titan. Differs as follows : front of head and end of palpus 

 blackish, black mesial line of occiput and collar heavier ; distal margin of forewing 

 in both sexes about 6 mm. shorter than internal one, the distal edge of the pale 

 area of the forewing more oblique between R' and R-, the blackish line proximally 

 of subcostal fork reaching down to R^ not developed to a large cloud or patch, the 

 following line baiely indicated, the line halfway between fork and apical jiatch 

 rather stronger marked than in titan. On the underside only the external one of 

 the three discal lines of the forewing is indicated, and there is on the hindwing just 

 a faint trace of the middle one of the three lines. 



c?. The diflerences in the sexual organs of the J are very marked ; the harpe 

 (PI. XXXll. f. 9) is raised to a low submesial ridge cm, which fades away distally 

 into the irregular folding of the inner sheath of the clasper, and which ends 

 proximally in a pointed small tubercle. The dorsal process jjd of the clasper is 

 similar to tiiat of phalaris. The tenth tergite (PI. XXIV. f. 'Z) is deeply sinuate, 

 the lobes are much broader than in titan and less sharply hooked (PI. XXIll. 

 f. 26) ; the steruitc is truncate, with the angles rounded and soruewhat curved dorsad-
