On unrlcrside broccoli-brown, the distal margins of liotli wings greyish white; 

 on the forewing a snbmarginal row of blackish vein-dots and proximally to this row 



two brown lines and traces of two others. Hindwing with a faint clayish tone ; 



between apex of cell and distal margin four lines ; anal angle blackish. 



Eighth tergite on inner side wirhont a lielt of friction-scales, and the claspers 

 without a patch of modified scales, both the belt and the patch being present in 

 rettisus, the former being visible in that species without dissection. Anal tergite 

 tapering to a point ; sternite absent as a distinct sclerite. ( !lasper short and broad 

 (text-fig. 1), apically divided into a short ronnded lower lobe (L') and a long dorsal 

 one (L-). This dorsal lobe is cnrved ventrad and also mesiad. Text-tig. 2 gives a 

 view of the apex of the clasper from a basal direction, so that the upper and lower

edges of the long lobe are in a plane. From the upper edge of the clasper a broad 

 truncate and denticulate lobe projects obliquely ventrad, the edge of this lobe being 

 continued distad anil extitiuling as a low ridge diagonally across the long ajiical lolie. 

 The penis-sheath, which in J', rr/i/sz/.s bears a very long recurved process, has a 

 broad oblique belt of teeth in spurreUi, the belt being open on the shorter and less 

 strongly chitinised side of the sheath. 



The clasper of /'. retinus R. & J. (lOnS), which we figure for (■(ini2)arison 

 (text-tig. :\), is much hmger and narrower than in P. spiirrelli ; its apical margin is 

 but feebly chitinised, somewhat swollen and very densely scaled ; the armature 

 consists of a conical thornlike process which lies partly concealed in the scaling 

 of the ventral margin and projects from a ridge as indicated in the figure. The anal 

 tergite of retusus is much more sharply pointed than in sjiunrl/i, and there is in
