Tlie two species treated iinder this new term come in general appearance as 

 well as in structure close to Xanthopan. They differ infer se rather obviously 

 in the one species (jasmini) having the midtibia spinose, while they are not spiny 

 in the other {lingen.i), in this respect jasmin i being the more si)ecialised si^ecies. 



S ? . Genal process triangular, almost reaching to the end of the pilifer. 

 Not scaled inner surface of first palpal segment quite naked ; third segment more 

 or less prominent, its tip not naked ; inner surface of second segment not concave. 

 Foretibia spinose, midtibia with or without spines ; first protarsal segment as long 

 as, or shorter than, the four others together ; mid- and hindtarsus with comb, 

 bristles of midtarsal comb gradually shorter, assuming gradually the length and 

 stoutness of the more distal sjjines, the comb differing in this respect obviously 

 from that of Xanthopan ; short spur of midtibia about half the length of the 

 long one ; first segment of hindtarsus at least half as long again as segments 2 to 5 

 together ; pnlvillus present : paronychium with two lobes at each side. 



S . Clasper with a patch of broad friction-scales, the scales nearly all minutely 

 dentate. Tenth tergite elongate, pointed, not divided, clothed with some long stiff 

 hairs ; sternite elongate-triangular. Penis-sheath with a long, slender, recurved 

 process, which points proximad and lies more or less closely upon the sheath. 



? . Eighth sternite short ; orifice of vagina transverse. 



Early stages not known. 



Hub. Madagascar. — Two species, both with the ground colour of the hindwing 

 yellow.

(? ? . Body and forewing whitish grey ; abdomen with whitish grey lateral 

 patches. Midtibia spinose ; first segment of foretarsus shorter than segments 

 ^ to 5 together, with some prolonged spines ; long terminal spur of hindtibia about 

 5 the length of first tarsal segment. Tliird segment of palpus rather prominent. 



S. Tenth abdominal tergite gradually narrowed to a point, slightly curved, 

 with some long stiff hairs, npperside strongly convex, extreme end suddenly 

 hooked ; sternite little shorter than the tergite, elongate-triangular, flat, the sides
