112 On new Species of Rhopalocera from Burma. 
brown instead of bluish fuscous. Underside no purple 
suffusion. 
A character common to both sexes is the almost complete 
absence of the discal zigzag fuscous fascia which crosses the 
middle of both wings in typical C. erota, the white band in 
the female and the lighter band in the male of Cynthia circe 
being almost immaculate. I have a series of males from 
Burma which present absolutely no variation in the characters 
described above, and I possess but one female from Toungoo, 
Burma, which is exactly matched by a female in the British 
Museum from Beeling, Tenasserim. If the C. asela of 
Moore, from Ceylon, is recognized as a species distinct from 
C. erota (Fabricius), this species must also be regarded as 
distinct, as the Ceylon form is much nearer C. erota (typical) 
in both sexes. 
Charaxes ajax, sp. n. 
Hab, Battak Mountains, Sumatra: June, July. 
Description.—Male. Allied to C. cor ax, Felder, from which 
it differs in the ground-colour of upper and underside being 
darker, the outer black band on the upperside of the fore wing 
being slightly broader and extending broadly black to the 
anal angle of the fore wing, its inner | edge straighter, as the 
crescentic markings are clearly detached in the intermedian 
spaces; two fulvous spots, the upper displaced outwards 
between the radial, and the lower in the following interspace, 
continuing the series of fulvous lunules formed ‘by the black 
crescents and the border. 
The submarginal black spots on the hind wing are larger 
and more triangular, their inner edges irrorated with black 
atoms, and the first four from the anal angle tipped with a 
minute white spot. ‘The underside is of a rich glaucous colour, 
in some lights inclining to purplish, much darker than any 
corax, more resembling some of the darker specimens of baya, 
Moore. The light violaceous antemarginal line is present in 
the fore wing, and within it are indistinct greenish lunules. 
In the hind wing a broad antemarginal band of olivaceous 
green, sinuated in each interspace, is bounded anteriorly by a 
narrow brownish border. 
The disk is crossed by the usual dark lines, the outermost 
bounded by olivaceous green irrorations, which are wanting 
in coraa.
