extends obliquely across the submedian and first median interspaces and 

 ends anteriorly on tlie second median nervnle a little in front of its origin. 

 HiNDWiNG, casta greatly arched at the base, thence straight to the apex ; 

 apex rather acute ; outer margin evenly and regularly convex to the anal 

 angle ; anal angle very acute ; abdominal margin straight ; the wing 

 extends a little beyond the apex of the abdomen ; the cilia towards the 

 anal angle very long ; costal nervure ending at the apex of the wing ; 

 first subcostal nervule arising long before the apex of the cell ; disco- 

 cellular nervules almost in one straight line, outwardly oblique, the 

 upper a little longer than the lower ; discoidal nervule obsolete, but 

 its position is indicated, were it to be present, by a fold in the wing 

 membrane, and by this fold the relative length of the disco-cellular 

 nervules is given ; second median nervule arising just before the lower 

 end of the cell ; first median arising about four times as far from the 

 second as the second does from the third ; suhmedian and internal 

 nervures straight. Legs. Hindleg with two pairs of spines on the tibia. 

 Sepa is nearest allied to Matapa, Moore, from the type species of 

 which it may be at once known by the discoidal cells of both wings 

 being more truncate at the end owing to the disco-cellular nervules 

 being less strongly oblique ; the shape of the wings differs also, the 

 inner margin of the foi'ewing in Matapa is longer than in Sepa, con- 

 sequently the outer margin in the former is less oblique than in the 

 latter ; the hindwiug differs in that, in Matapa, the anal angle appears to 

 be somewhat produced owing to the wing about the termination of the 

 first median nervule being somewhat eraarginate, in Sepa the wing is 

 evenly curved throughout. Type, Sepa cronus, de Niceville.

Habitat : Battak Mountains, N.-E. Sumatra. 



Expanse : c?, T? inches. 



Description : Male. Upperside, hotJi tvings rich dark shining 

 brown. Forewing with three pale ochreous dots, two subapical, the 

 anterior one most minute, the third in the second median interspace 

 about twice the size of the lower subapical spot ; a narrow obscure discal 

 black stigma or " male-mai^k " crossing obliquely the submedian and 

 first median interspaces, that portion of the stigma in the latter inter- 

 space having a prominent pale ochreous semi-transparent line placed 

 outwardly against it. Hindiving immaculate. Underside, both wings 

 exactly as above except that the ground-colour is dull, not shining. 

 Cilia concolorous with the wings throughout, those of the hindwing at 

 the anal angle unusually long, though not quite as long as in Lophoides
