other. Hindwing with a large round black spot at the apex • a sub- 

 marginal ochreous line. Female. Upperside, both wings dead plumbeous- 

 black, Foreioing with a short streak of blue scales in the lower 

 discoidal interspace beyond the end of the discoidal cell. Hindwing 

 unmarked. Undersidk, both wings as in the male. Cilia throughout 

 more prominently marked alternately black and white than in the male. 



A comparison of the figure here given of the male (which, how- 

 ever, is a very poor one, drawn from a very small specimen, the first 

 I received), with that of Pithecops fulgens, Doherty,* from Margherita, 

 in Upper Assam, of which I possess three males and two females, 

 including the type specimens, will at once disclose the fact that on the 

 upperside the male of P. marice has the blue area of much greater 

 extent (it is also of a deeper, more truly blue, shade), and on the 

 undei'side, that it is far less heavily mai-ked, the two costal dots of the 

 forewing being often absent, and the apical spot of the hindwing often 

 smaller. 



The discovery of a second blue species of the genus is highly 

 intex'esting. I have described it from several male examples received 

 from Hofrath Dr. L. Martin • one taken by myself at N"amoe Oekor in 

 October, in the virgin forest, and three female examples in my own 

 collection, and one in Dr. Martin's, after whose amiable wife I have 

 great pleasure in naming it. Though this butterfly is so small, the 

 male immediately attracts attention when flying by the wonderful 

 refulgence of the coloration of the upperside of the wings.

 m^edian interspace. Underside, both ivings dead white, all the black 

 markings unusually large and prominent ; a marginal series of prominent 

 spots, oval in the forewing, round in the hindwing ; a submarginal promi- 

 nent line, broader and lunulated in the foi-ewing, narrower and more 

 highly lunulated in the hindwing ; a very fine anteciliary black thread.
