iS ?. Thorax with short yellow mesial stripe, correspoudiug to the mesial stripe 

 of F. zagreus and allies. Abdomen with broad creamy yellow lateral strii)e. 

 Costal edge of forewing practically non-serrate. Disc of hindwing abode with 

 greyish green or greyish blue patches. No discal band on underside of hindwing ; 

 a creamy spot near anal angle being all that is left of the band ; red submarginal 

 spots large. The female is dimorphic : 



a'. ?-f. xanthopleura is similar to the male, the bluish area of the hindwing 

 being larger. 



b'. ? -f. diaphora Stand., I.e., bears a large creamy yellow central area on the 

 forewing occupying the greater part of the cell and the disc between the median 

 and lower radial veins, the bluish scaling of the hindwing being reduced to a 

 narrow band. 



Nenration : SC- of hindwing at one-third from base to R^ 



Genitalia: c?. Tenth tergite long, strongly narrowing distad, rounded-dilated at 

 the apex ; sternite on each side with two processes, the anterior one triangular, 

 multidentate, the posterior one rather longer, narrower, slightly acuminate, concave 

 on proximal surface ; harpe broad, gradually narrowed from middle to base, dorsal 

 edge of apical half somewhat elevate, densely denticulate, apex rotundate, longi- 

 tudinally grooved, bearing a great number of small conical teeth at and near the 

 edge; no process. ? not examined. 



Early stages not known.
