also crossed by several pale ochreous bands in continuation of those on the forewing, viz., a 

 basal one, a subbasal one reaching the submedian nervure, the disco-cellulars defined by a 

 third, another discal reaching the first median nervule, thence to abdominal margin forming 

 a W-shaped figure, a fifth beyond joined to the fourth at the first median nervule. A 

 broad ochreous band from the discoidal nervule to the anal angle, the outer margin marked 

 as in the forewing, but the fine lower black spots placed within the submarginal lunulated 

 white line more distinct. Underside marked as above, but all the bands crossing the 

 wings narrower and less distinct, the anal lobe of the hindwitig marked with a diffused 

 prominent black spot. Female rather larger, the basal portion of both wings has the ground- 

 colour very pale sap green. C. periander is the only Indian species with the apex of the 

 forewing truncate. 



Dr. Anderson took very numerous specimens of C. periander in the Mergui Archipelago 

 in the cold weather, it occurs in Tavoy, Mr. Westwood* records it from Mysore, and it was 

 taken by Dr. Horsfield in Java. Mr. Butler (1. c.) records it from Assam {^Warivick),h\x\. 

 as in the case of all the species given under this reference, the specimens probably came from 

 Burma on the Malay Peninsula. 



The remaining species are of very small size, and have the second subcostal nervule of 

 the forewing emitted beyond the apex of the cell.

Habitat : Kumaon, Sikkim, Assam, Upper Tenasserim, Java. 



Expanse : 1*65 to i'95 inches. 



Description : Male. Upperside, both wings rich ochraceous ; crossed by a basal 

 pair of fine black straight lines, the space within irrorated with black scales, another pair 

 beyond, two similar discal lines, the outer one with a series of pale ochreous triangular 

 spots placed inwardly against it, more prominent on the hindwing ; followed by a steel-blue 

 line, somewhat macular on the forewing, where it is divided in the middle by a pale ochreous 

 patch and another at the apex, a submarginal fine black line outwardly more or less marked 

 Willi pale ochreous patches, and a similar marginal line. Forewing with a basal line, the disco- 

 cellulars defined on both sides with a fine black line, a single line defining those nervules on the 

 hindivino. Underside a little paler than above, the spaces between the fine black lines paler 

 and faintly tinged with violet, the markings much as above. Female rather larger, the 

 wings broader, markings similar but paler. Mr. Doherty writes (1. c.) :— " Kumaon specimens 

 are lighter in colour and more delicately marked than Sikkim ones. Three of the bands 

 below are in both sexes beautifully glossed with lilac on the hindwing, and to a less extent on 

 the forewing." 



C. risa is a common species in Sikkim at low elevations, and occurs to the eastwards as 

 far as Sibsagar in Upper Assam at any rate, and again in Upper Tenasserim, Mr, Moore 

 recording it from "Moulmein to Meetan ; Moolai, 3,000—6,000 feet."

 Expanse : i -3 to 1 7 inches. 



Description : " Male and female. Upperside, both wings pale ochraceous, crossed 

 by the following fascise :— a somewhat curved basal dark ochraceous fascia, margined with 

 fuscous, commencing at about subcostal nervure of forewing and terminating slightly beyond 

 submedian nervure of hindwing ; this is followed by a straighter but more irregular fascia of 

 the same colour, which, commencing abou t costa of forewing, pa ss es the cellular apices o f
