of the antennae black anteriorly dotted with white, not anteriorly 

 wholly silvery-white. The male differs from G. pulomaya, Moore, 

 fromKuln, Sikkiin, and Bhutan in having the lower of the two spots 

 placed obliquely in the submedian interspace of the forewinginboth 

 sexes white, in C. fulomaya it is yellow. C. putra, Moore, from 

 Bengal, is unknown to me; the description agrees, however, with 

 some examples of C. leucocera, Kollar. 



Described from a single male from Bhutan (I have examined the 

 prehensores, so am certain that the specimen is a male), and six 

 females also from Bhutan, one female from Chenrapunji, and one 

 male and three females from the Khasi Hills. 



18. (14) CEL^ENORRHINUS PLAGIFERA, n. sp., VI. B, 



Fig. 13, ?. 



Habitat : Sikkim, Bhutan. 



Expanse : £ , $ , 2'0 to 2*3 inches. 



Description : Male and female. Upperside, forewing differs from 

 C. pyrrha, mihi, in never having a spot one-tbird from the base in 

 the submedian interspace. Hindwing with the spots larger, and of a 

 richer (more orange) yellow colour ; the alternate yellow portions of 

 the cilia also of a deeper orange. Underside, forewing lacking the 

 two diffused whitish spots in the submedian interspace beyond the 

 two obliquely-placed transparent spots which are found in C.pyrrh a; 

 otherwise as in that species. Ant entice as in C. pyrrha, 



I have described this species from nineteen specimens in the 

 collections of Mr. A. V. Kny vett and myself. It appears to be very 

 constant. The sexes are very difficult to discriminate ; I have been 

 able to distinguish them only by an examination of the organs of 

 generation. 



19. (15) CEL^ENORRHINUS PATULA, n. sp., PI. B, 



Fig. 4, $ . 



Habitat : Sikkim. 



Expanse : 6,2-2; 9,2-5 inches. 



Description : Male. Upperside, forewing with the white spots 

 forming the discal band smaller than in C. pyrrha and C. plagifera, 

 mihi, no spot at the base of the second median interspace, the lower 

 of the two spots in the submedian interspace minute. Cilia anteriorly 

 dark brown, posteriorly pale yellow. Hindwing with the yellow spots 

 on the disc larger and clearer than in either the above-mentioned 

 species. Cilia almost entirely yellow, instead of being prominently
