the antennae of the sexes did not differ : the cocoon is reti- 

 culate and silvery. 



GoNiMBRASiA, n. gen. 



Allied to Imhrasia^ but the antennse of the males pectinated 

 to the apex, the outer margin of the primaries usually 

 straighter, the outer margin of the secondaries obtusely sub- 

 angulated, not caudate. Type O. nictitans. 



To this genus may also be referred Imhrasia rhodophila 

 and /. alopia. 



Gonimhrasia ohsciira, n. sp. 



Primaries dull reddish brown, ferruginous towards the base, 

 clouded with fuliginous at and beyond the end of the cell, 

 speckled with grey upon the external area ; a dusky inter- 

 rupted zigzag transverse streak, broadly bordered externally 

 by a diffused pink belt, limiting the basal area, a nearly semi- 

 circular hyaline white spot at the end of the cell ; an oblique 

 diffused dusky stripe, from costa to inner margin, immediately 

 beyond the hyaline spot ; a dark brown oblique discal stripe, 

 parallel to the outer margin, bordered on both sides by pink 

 stripes, the outer one irregularly sinuated, both diffused and 

 expanded at the costa, so as to form a broad costal patch : 

 secondaries olive-brown, becoming fuliginous towards the 

 centre of the wing ; abdominal border reddish ; base rosy ; 

 two divergent white stripes from the abdominal border to the 

 subcostal vein, the outer one obtusely subanguhitcd and 

 bounded externally by a narrow blackish stripe ; a large cen- 

 tral ocellus touching the outer stripe gravel-yellow, with semi- 

 circular hyaline white centre, black iris, dull lake-red margin, 

 and pink border ; disk from the abdominal margin to the 

 radial (or third subcostal) branch traversed by a pinky-white 

 zigzag squamose stripe : body clay-coloured, becoming ferru- 

 ginous towards the head, posterior border of thorax pink. 

 Wings below altogether paler, broadly tinted with pink, the 

 stripe neai'est to the base of primaries obsolete, the stripe at 

 the end of the cell very broad and diffused ; two dusky discal 

 stripes, beyond which is a broad zigzag pink stripe : secon- 

 daries with an ill-defined dusky stripe beyond the black stripe ; 

 ocellus reduced to a hyaline spot with fulvous margin ; zigzag 

 discal stripe continued to the first subcostal branch : body 

 clay-coloured, uniform in tint. Expanse of wings 5 inches. 



Old Calabar. 



This genus is most nearly allied to Buncea both in pattern 

 and structure, but differs in its shorter antennje and more 

 angular secondaries.
