The sexes dissimilar, tlie females being again diclaromatic. The hind wing 

 strongly dentate. 



c?. Upperside: band almost gradnally widening from apex of fore wing to 

 abdominal margin of hindwing, narrower than in /'. lamarchei, varying somewhat 

 in width and also in tint ; many specimens with a sjjot before SC'\ others being 



without it. Hind wing : from one to six red spots on disc, the anal submarginal 



spot being also red. — Cell of forewing striped beneath. 



? . Band of wings, if present, white, usually not extending to abdominal margin 

 of hindwing, stopping at M or at M' or IP ; on forewing somewhat different in 

 position from the band of male, being nearly parallel to distal margin, slightly 

 curving away from it anteriorly, crossing the subcostals just outside fork. Sub- 

 marginal spots of hindwing red, thin. Three colour-forms : 



a. ?-f. heetorides Esp., I.e.; mecentius Doubl., I.e.; argentus Gray (ex 

 Martyn), I.e. — Both wings with white baud ; the band in one of our specimens 

 continued to abdominal margin of hindwing by means of two white spots which are 

 merged together with the last two red spots of the discal series ; the band very 

 variable in width. 



Ij. ¥ -f. catamelas nov. — Band vestigial on forewing, distinct on hindwing, but 

 rather narrower than in ?-f. heetorides. 



c' . ?-f. melania Oberth., I.e. — Band vestigial on both wings or absent. 



Genitalia : J. Tenth tergite long, spatulate ; sternite laterally with a ridge 

 which is transversely divided into two short tubercles or teeth, the proximal one being
