(listally not turned upwards, apex obtusely pointed. Clasper : patcli of large 

 friction- scales on the outer side not sharply defined, dentition of these scales rather 

 heavy ; harpe inilicated by an iucrassation of the ventral margin of the clasper, 

 densely clothed with sliort scales ; «o free process. Penis-sheath: pointed process 

 apicaliy curving laterad (PL XXVIII. f 3(i). 



?. Vaginal plate short ; a flat, transverse, rounded ridge behind the vaginal 

 opening more strongly chitinised, brown, the rest of the plate membranous ; month 

 of vagina transverse, subapical (PI. XXI. f '.)), the membrane convex mesially on 

 aoconnt of the internal vaginal tube being rather strongly chitinised.

S S . Much darker than the preceding ; abdomen witli yellow lateral jiatches. 

 The yellow discal band of the hindwing sometimes reaching costal margin, but 

 mostly shaded with black or brown in anterior half Third segment of palpus 

 less prominent than in jasmini. Midtibia not spiny ; first segment of foretarsns 

 as long as segments 2 to 4 together ; long terminal spur of hindtibia not much 

 over half the length of the first tarsal segment. Antennae of c? thicker than in 

 janmini. 



i . Tenth abdominal segment not obviously different from that oi jasmini, the 

 sternite less flat, the margins somewhat turned upwards. Clasper : patch of 

 modified scales longer, better defined, the scales less denticulate ; harpe small, 

 not scaled on the inner surface, but clothed with some hairs, with two apical 

 tooth-like processes, both triangular, one pointing distad, the other elorsad 

 (PI. XXXV. f 11). Process of penis-sheath as m ja.smini, less curved apicaliy, 

 witli a minute tooth-like carina before end. 



?. Vaginal plate as short as in jasmini, esi>ecially the postvaginal portion, 

 which is reduced to a transverse stripe ; much more chitinised than in jasmini 

 except quite proximally ; mouth of vagina very transverse, covered in front by a 

 rounded, transverse ridge, which is mesially sharply rounded-sinuate (PI. XXI. f. 10). 



llab. Madagascar ; apparently rarer than the preceding.

This and the preceding may perhaps be gcnerically distinct from one another. 

 The dift'erences in structure which we have found are noted above ; the si>inosily 

 of the midtibia m jasmini is the most prominent difference.
