both of which T. hlanha may instantly be known by the forewing on 

 the underside having no markings whatever. 



Described from a single example in Dr. Martin's collection, which 

 was taken in October. Namoe Blanka is the name of a Battak kam-

35. Chaeana cepheis, n. sp., Plate V, Fig. 10, c?. 



Habitat: Assam. 



Expanse : <?, 1*8 inches. 



Description : Male. Upperside, both wings glossy purplish-black. 

 Forewing with the basal two-thirds of the interno-median area ending 

 outwardly in a point and the basal half of the sutural area rich deep blue 

 of about the same shade as in the male of Camena icetas, Hewitson. 

 Hinchving with the outer half from the second subcostal nervule to the 

 submedian nei'vure, crossed by the black veins, rich deep blue ; a diffused 

 and indistinct submarginal black spot in the first median interspace ; the 

 outer margin narrowly black ; the anal lobe orange-ochreous, bearing a 

 few white and blue scales ; the tails black, fringed and tipped with white. 

 Underside, loth wings with the basal two-thirds pale chrome-yellow, the 

 outer third purplish-brown. Foreioing with the purplish-brown area 

 bearing two macular deeper brown bands, which are farthest apart in the 

 middle but meet at each end, thus enclosing an oval space of the ground- 

 colour ; a submarginal whitish thread reaching from the anal angle to 

 the middle of the wing. Jlindwing, the outer purplish-brown area bears 

 two macular deeper brown bands, the inner one posterioi'ly highly zig-zag 

 and recurved to the abdominal margin, the outer one reaching only to 

 the second median nervule ; the first median interspace bears a round 

 black spot with an outer rust-red ring; the anal lobe is jet-black, 

 anteriorly bearing a few turquoise-blue scales, and bearing anteriorly 

 to these again a rust-red line, which is continued to the abdominal 

 margin along the edge of the incised portion of the wing anterior to 

 the anal lobe, this red line defined on both sides with a very narrow 

 black line. Cilia of the hindwing narrowly tipped with white, those 

 of the forewing black. 



This species is very near to G, mandarinus, Hewitson, from Sikkim, 

 Bhutan, Assam, and Burma, from which it differs in the following 

 particulars : — The blue coloration of the uppei-side is quite different, 

 being of a much darker and richer hue, in C. mandarinus it is distinctly 

 " dull cerulean blue," the blue colour also does not extend into the 

 discoidal cell of the forewing as it does in that species ; on the under- 

 side the outer area of both wings is purplish-bx'own instead of rufous, 

 in the forewing the macular bauds touch at both ends instead of being
