of hindtibia less than half the length of the first tarsal segment. Distal margin 

 of forewing almost straight in c? ; bisinuate in ? , with a prominent lobe at R', 

 hinder angle a little ]>rojecting backwards. D-. of hindwiug twice as long as D', 

 very oblique. Abdominal tergites not sjiinose excepting edges, underscales large- 

 Clasper and eighth tergite with organ of friction. 



There are two species known to n.s, which are almost exactly the same in pattern; 

 they can be distingnished, apart from strncture, by tiie one species having npon 

 M^ of the forewing in front of the tawny spot standing at inner margin close to 

 angle one larger black dot accompanied at the ])roximal side by the vestige of a 

 second dot, while the other species has two small black dots of equal size instead 

 (PI. LXV. f. 17. 18). The former insect is paupevcula, the type of which is an 

 abnormally large individual. 



(J. The tenth tergite is very slender and long, curved downwards, not acutely 

 pointed (PI. XXV. f. 18, side-view) ; the sternite has a large lobe, which is some- 

 wliat dilated laterally, rounded, sliglitly sinuate mesially (PI. XXV. f. 17. Xr, 

 dorsal view). (Uasper elongate, dorsal margin slightly concave, convex before 

 end, apex rounded, ventral margin slightly convex ; the patch of friction-scales 

 subapical, ovate, the scales narrow, pointed, conspicuously different from the other 

 scales of the clasper not only in structure but also in colour, being huffish, not 

 greyish white ; eighth tergite with a belt of friction-scales at the internal edge, 

 the scales not very large, but regular in position ; harpe (PI. XXXIII. f. 24) 

 a broad ronuded flap, concave, dorsal part rough with short spines, sometimes more 

 truncate than in figure. Penis-sheath with a long apical process curved proximad, 

 the jirocess stout, conical (PI. XXX. f. 42). 



?. Vaginal jilate (PI. XVII. f. 17) raised to a rather high ridge before the 

 orifice ( » ), this ridge (avp) broadly and shallowly sinuate, without processes ; 

 postvaginal jiart of plate {uvp) membranaceous, short.

224. Polyptychus hollandi spec. nov. (PL V. f. 3, ■i). 



d. Very close to pdHperciihi, deeper brown. Markings of wings as in paiipnr- 

 cula ; but the tawny spot at the inner margin near angle smaller not reaching vein 

 M-, and there are two minute black dots in front of it upon M^, the external one 

 of them not being larger than the dots upon M' (PI. LXV. f. 17). Marginal 

 area of hindwing as far as the series of dots rather darker in tint than the disc in 

 paiijiercida, while the disc is as dark as the marginal area in hollandi. The tenth 

 tergite is carinate above, hence broader in side-view (PI. XXV. f 19); the harpe 

 is deejdy sinuate (PI. XXXIII. f, 2.5), and the, hook of the penis-sheath (PI. XXX. 

 f. 43) is slenderer than in paupevcula.
