[Plate VIII.] 



Polyptychus lapidatus, J. & K. 



(J. Differs from P. muruiuSj Roths. (1904), in the 

 following points : — 



Smaller; distal margin of fore wing a little less incurved 

 and darker brown than in P. muriaus, the ante- and post- 

 median lines less irregular, the anteinedian ones ending at 

 hind margin, with a conspicuous brown spot composed of two 

 arcs; the postmedian lines, which in P. muri7ius are crenate 

 or dentate in front of the hind margin, being strongly marked 

 in this area, are in lapidatus feebly marked, not contrasting 

 much with the ground, a somewiiat diifuse brown spot at 

 hind margin near angle being the most conspicuous marking 

 in this area. Anal angle of hind wing less produced than in 

 P. viuriints, the apex of hind wing broader, the brown anal 

 submarginal spot continued forward. 



Underside : costal margin of fore wing and the hind wing 

 with the exception of the distal and abdominal marginal areas 

 laved with ferruginous, almost as in P. murinics ; fore wing 

 with a somewhat dentate postdiscal line, and further towards 

 margin two rows of minute dots, the inner dots being connected 

 with one another bv a very faint brown line. On hind wing 

 three brown lines.' 



Genitalia similar to those of P. murinics, but anal tergite 

 slenderer and comparatively larger. Theclasper (fig. 2) with 

 a small, well-defined patch of small yellowish scales on the 

 outside near apex ; the upper process of the harpe (P^) 

 directed obliquely downwards, very much shorter tlian the 

 corresponding process of P. ynurinus ; moreover, in P. 7nurinus 

 F^ is almost liorizontal, being directed towards the apex of 

 the clasper, which it reaches ; process P- is denticulate and 

 touches P^ apical ly ; below P' tliere is a short lobe L. The 

 penis-funnel is armed below the penis-sheath with two conical 

 thorn-like teeth which are curved upwards ; in P. niurinus 

 the two prongs of this fork are almost divaricate, while in 

 lapidatus they are divergent. (For the meaning of these 

 termini see Lacordaire, Genera Coldopt. ix. 2, p. 412, 1872.) 

 The genitalia of two S S of P. inurinus have been compared, 

 one from the Congo, the other from the Gold Coast.
