wticli are two lowei'-discal bluish-grey elougated streaks, the lowest being much the 

 longest, followed by an outer-discal series of prominent greyish-white sagittate 

 marks, of which the upper tliree or four are elongated and narrow. Hindvnnc/ with 

 the red tint of the subbasal band of the underside slightly apparent ; a bluish-grey 

 transverse broad band extending from middle of the costa and widening across 

 middle of the cell to base of the lower median interspace, beyond which is a prominent 

 greyish- white small oblique spot on the lower discocellular veinlet, followed by an 

 outer discal curved series of five more or less prominent similar-colonred narrow 

 sagittate marks, the submedian and abdominal interspace to near both their ends 

 being pale yellow. Underside duller black. Foreioing with prominently greyish- 

 white medial-cell bar, lower-discocellular spot and a contiguous upper-discocellular 

 broken spot, the lower-discal outwardly oblique streaks, and the outer discal 

 transverse series of marks. Hindioing with a crimson baud curving from base of the 

 costa across the cell beyond its base to the abdominal margin, followed by a 

 prominent pale yellow apical cell patch — of which its upper inner end is sometimes 

 broken, upper-discal spots and then a submarginal curved series of spots — of which 

 the upper are oval, the lower elongated, the two lowest being united from the lower 

 median to the abdominal margin. 



Female. Upperside dull black. Forewing with the cell-bar and lower-discal 

 streaks whitish, and as well-defined as the discocellular spot, and the outer discal 

 series of streaks, the two lower discal being, generally, short and broad. Hindwing 

 Avith the transverse medial-band with its conjoined discocellular spot, broad 

 abdominal area and discal series of streaks, all vmiformly whitish, the latter streaks

Lakva and Pupa (Plate 531, fig. 1). — "Larva feeds on the parasitic plant of the 

 Roghu tree {Naudca Cadaviba), congregating together, closely packed. Pupa 

 formed February 1st, 18S0 ; imago emerged Feb. 18th " (Mrs. E. M. Span, MS. Notes, 

 Nowgong, Assam). 



DisTEiBDTiON. — We possess specimens of both sexes from Noakote, Nepal, taken 

 by the late Gen. Gr. Ramsay ; also from Sikkim, Cachar, and Silhet. Mr. H. J. 

 Blwes records it as " not uncommon in Sikkim, up to about 3,000 feet elevation, 

 from April to December" (Tr. Eut. Soc. 1888, 407). Mr. L. de Niceville says that 

 " it occurs in Sikkim, in the low hot valleys commonly throughout the year, except 

 perhaps in the two coldest months " (Sikk. Gaz. 18U4, 165). Col. C. Swinhoe has 

 specimens from Cherra Punji in Assam, and from the Khasia Hills. In the British
