PLASTINGIINJE. 213 



elongate, one in the lower sub-costal space, quadrate, and three in the median and 

 sub-median spaces, in a line receding from the border. Cilia ochreous. 



One male, Margherita, and a similar one, Sadiya. The species is a local form 

 (differing in the large sub-apical spots, the absence of the outer — fourth — discal sput. 

 the undivided cell-spot separated from the interno-median one, and in the ochreous 

 patch of the hindwing consisting of two hyaline and one opaque space and confined to 

 the disc) of another found in the three ludo-Malayan islands, the Malayan Peninsula 

 and Mergui, but everywhere rare. The Javanese form {calllneura) seems, judginf from 

 my specimens, to dift'er but slightly. The single, very worn ]\lergui specimen, taken 

 by Dr. Adamson, has been identified by Mr. Moore as PlastiiKjia latoia, Hewitsun. 

 But that species (and P. calUneura, Felder, which is regarded as conspecific with it) 

 has been described and figured by Hewitson, Felder and Distant, with uchreous sub- 

 marginal spots on the hindwing below, no blue ones being mentioned. In any case 

 the above-mentioned characters separate my species as a distinct local form. 



The egg of several species of Plastingia examined by me generally resembles that 

 of Snastus. But like those of Hesperia satwa, de Niceville, and the species of Cuj'it/ia, 

 though in a lesser degree, it possesses a large crown-like mass of white cells apically, 

 surrounding the micropyles, as delicate in structure as the finest lace. They are the 

 most beautiful butterfly-eggs known to me. (Doherty.) 



Expanse of wings, $ 1^ inches. 



Habitat. — Assam. 



Distribution. — The unique type from Margherita, in Upper Assam, is in (.'oil. 

 Elwes ; we have not seen it, and therefore give copies of Doherty 's fio-ure.
