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 projecting backwards. D^ of hindwing twice as long as D', 

 very oblique. Abdominal tergites not spinose excepting edges, nnderscales large- 

 Clasper and eighth tergite with organ of friction. 



There are two species known to ns, which are almost exactly the same in pattern; 

 tliey can be distingnished, apart from strncture, by tlie one species having upon 

 M- of the forewing in front of the tawny spot standing at inner margin clos(! to 

 angle one larger black dot accompanied at tlie proximal side by the vestige of a 

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

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

 abnormally large individual. 



S . The tenth tergite is very slender and long, cnrved downwards, not acntely 

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

 what dilated laterally, rounded, slightly sinuate mesially (PI. XXV. f. 17. Xv, 

 dorsal view). CUasper elongate, dorsal margin slightly concave, convex before 

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

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

 scales of the clasper not only in structure but also in colour, being buffisli, 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 rounded flap, concave, dorsal part rough with short spines, sometimes more 

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

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



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

 orifice {c), this ridge {avp) broadly and shallowly sinuate, without processes ; 

 postvaginal part of plate {uvp) membranaceous, short.

224. Polyptychus hoUandi spec. nov. (PI. V. f 3, i). 



S. Very close to jtunpinrida, deeper brown. Markings of wings as in pauper- 

 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 

 paiipercula, while tlie disc is as dark as the marginal area in hoUandi. The tenth 

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

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

 f 43) is slenderer than in paupercula.
