distally luit liinicd upwards, a])e.\ obtusely iiointeil. (^lasjjer: )iatcli of large 

 frictiou- scales on tlie outer side not sharply defined, dentition of these scales rather 

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

 densely clothed with short scales ; wo free process. Tenis-sheath : pointed process 

 ai.ically curving laterad (PI. XXVIII. f. 30). 



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

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

 of vagina transverse, subapical (PI. XXI. f. 9), tlie membrane couve.x mesially ou 

 account of the internal vaginal tube being rather strongly chitinised. 



Hub. Madagascar, apparently all over the island in siiitable places.

c?$. Much darker than the preceding ; abdomen with yellow lateral i>atclies. 

 The yellow discal band of the bindwing 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 S thicker than in 

 jasmini. 



S. Tenth abdominal segment not obviously different from tliat oi jasmini, the 

 stemite 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 dorsad 

 (PI. XXXV. f. 11). Process of penis-sheath as in jasmini, less curved apically, 

 wit!) a minute tooth-like carina before end. 



?. Vaginal plate as short as in jasmini, especially 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). 



Haij. Madagascar ; a2323ai'ently rarer than the preceding.

This and the i)receding may perhaps be generically distinct from one another. 

 The differences in structure whicli we have found are noted above; the sjiinosily 

 of the midtibia m jasmini is the most prominent difference. :
