P. agartis. A white band from costal margin of forewing to anal angle of liiiidwlng,

 latter being broad, apes of harpe feebly acnminate, a little cnrved ujiwards, 

 ventral and apical edges dentate, at base of harpe two heavy conical teeth, both

J?. Upperside metallic, especially tlie hindwing, which has a strong blue 

 gloss in male, being less strongly glossy in female ; scales of ujiperside feebly 

 dentate, the njiper scales partly entire in male, the same being the ca-^e in the 

 jiosterior area of the underside of the forewing ; no markings on forewing, e.xcept 

 the distinct white fringe-spots ; bnt one of our females has a row of indistinct 

 jiinkish grey jiatches about 5 mm. distant from distal margin, the row curving 

 costad in front, the tirst spot standing behind R' and the last before SM-, this 

 last sjiot being present in several other specimens ; this row of jiatclu s corresjionds
