Genitalia: d. Tenth tergite slenderer than in P. jjroneus. Ilarpe long, 

 kuife-like, the distal half denticulate ventrally ; apex rounded dorsally, being 

 veutrally acuminate and somewhat twisted. Penis-sheath acuminate ; a flat, 

 rounded disc of chitin jirojecting ventrally from the orifice of the sheath, the 



disc being continuous with the membranaceous ventral portion of the sheath. 



?. In front and at the sides of the vaginal orifice an irregular ridge, much folded, 

 being semi-membranous, forming a ring which is open distally in the middle ; 

 within this ring and just behind the vaginal orifice a short process, curved anad, 

 being convex ventrally, hollowed out on hinder (or upper) side ; the membrane 

 connecting the ridge with the seventh sternite den.sely folded, there being a more 

 strongly chitinised, smooth, rounded lobe laterally where this membrane joins the 

 seventh sternal sclerite ; in a non-virgin female the central process is envelo})ed by 

 a hardened substance blocking up the vaginal orifice. Anal segment with numerous 

 short stout bristles.

(? ? . Red submarginal spots of hindwing transverse, oblong or Inniform, not 

 sandglass-shaped as in F. chamissonia ; anal spot not V-^^li^-peJ, there being uo 

 discal spot proximally of the anal submarginal one. Width of central band and 

 the number of spots composing it on hindwing variable. Foretibia and first 

 foretarsal segment more finely hairy, less spinose, than in P. ugams. 



Genitalia different from those of the allied species, the female bearing after 

 copulation a kind of pouch, externally visible and homologous to the pouch of 



Euri/ar/c.s, Pafncissiii.'<, and Acraea. S- Tenth segment as in the allied species, 



the tergite being very long and slender. No separate harpe on clasper, the harpe 

 being rej(resented by a polished central space which extends from base to middle, 

 being rounded distally ; this space depressed, a triangular distal portion of it being 

 slightly elevate ; ventral edge of clasper with a short stout conical tooth. Peiiis- 



shcatU strongly chitinised at apex, ending in a sharp point. -?. In a virgin 



specimen there is at each side of the vagina a large flap, rounded, asymmetrical, 

 bearing distally several carinae, the two flaps inclining towards each other ; from
