KEW AND LITTLE-KNOWN INDIAN BUTTERFLIES. 183 



marked with black at the ends of the veins. Antennae 

 with the shaft anteriorly entirely pure silvery-white, in which respect 

 it agrees with G. sumitra, Moore, and G. pcro, mihi. Female, 

 Upperside, forewing with the lower spot in the subtnedian interspace 

 larger than in the male, as also are the five subapical spots; a 

 minute spot at the base of the second median interspace. Cilia 

 posteriorly barely marked with pale yellow. Antennae, as in the male. 



G, patula differs from the descriptiou of G. sumitra in having 

 two spots in the submedian interspace of the forewing in both 

 sexes instead of one only, the cilia are not alternately broadly brown 

 and orange-yellow, and the female of 0. patula lacks the yellow 

 costal spot above the oblique discal series of white spots on the 

 upperside of the forewing described in C. sumitra. 



Described from a single pair from Sikkim. The female of C. 

 patula is unique as far as I know amongst this group of the genus 

 in possessing antennas that are anteriorly white, this being usually a 

 male character. I am certain of the sex of my type specimens, as 

 I have examined the primary sexual organs. 



20. (16) CELiENORRHINUS PERO, n. sp., PL B, Fig. 12, J . 



Habitat : India. 



Expanse : 5 , 2*2 inches. 



Description : Male. Upperside, both wings differ from those 

 of C. pyrrha, mihi, in being paler in colour. Forewing marked as in 

 that species, but the yellow spot one-third from the base of the wing 

 in the submedian interspace more prominent ; cilia broadly pale 

 yellow and brown. Hind wing as in G. pyrrha, but the yellow spots 

 on the disc smaller, and the cilia almost entirely pale yellow, only 

 just touched with brown at the ends of the veins, as in G. patula 

 and C. jlavocincta. Underside, both tvings as in C. pyrrha, but the 

 spot one-third from the base of the submedian interspace of the 

 forewing much larger than on the upperside and white. Antennas 

 shining silvery white anteriorly throughout, posteriorly black. Palpi 

 white below instead of pale yellow as in G. pyrrha. 



C. pero agrees with G. sumitra in having the antennas anteriorly 

 white, but differs from the description of that species in having the 

 palpi and front of the thorax beneath white not pale yellow, and in 

 possessing the additional yellow spot one-third from the base and 

 the white spot one-third from the outer margin in the submedian 

 interspace of the forewing on the upperside.
