Imago. — Male. Upperside as in the wet-season form, thougli of somewhat paler 

 rufous-brown, and paler brown margins. Forewing with a minute black dot in the 

 upper discoidal, and an ocellus between the lower medians. Hindwing with a 

 similar subbasal and a submedian tuft of hairs. Underside. Both wings with the 

 slight dusky subbasal line, and the olivescent-grey transverse discal band ; marginal 

 lines pale. Forewing with a minute subapical and median white-pupilled black spot. 

 Hindioing with seven minute similar white-pupilled dots, the fifth being somewhat 

 the largest. Female unknown. 



Expanse, 2^ inches. 



Habitat. — Upper Tenasserim ; Malay Peninsula; Sumatra. 



Distribution. — Within our area, the dry-season form {Surlcha) was taken by 

 Capt. C. T. Bingham in January, in the Donat Range, Upper Tenasserim, and also 

 in the lower Thoungyeen forests (Butt. Ind. i. 133). Mr. H. J. Elwes (J. A. S- 

 Beng. 1887, 418) also records "three males from Tavoy and one from Ponsekai." 

 The wet-season form (which I take to be the ustulaia of Mr. Distant) was taken by 

 Herr Kunstler at Perak, in the Malay Peninsula. A male of this latter form, from 

 Sumatra, is also in the British Museum Collection. 



Of the illustrations of this species on our Plate, No. 73, fig. 3 represents the 

 male of the wet-season form (copied from Mr. Distant's Rhop. Malayana, pi. 41), and 

 fig. 3a, that of a male of the dry-season form, cojDied from Mr. Marshall's figure in 

 J. A. S. Bengal.
