S ? . Tibiae sliorter scaled than in vitis. First segment of hindtarsus very 



little shorter than tibia. Forewing, above, with a single straight line behind 



base of iP, at right angles to liinder margin ; stigma ai){)earing simple, triangular, 

 owing to the proximal part (within cell) being scarcely deeper in tint than the 



rest of the cell. Hiudwing without black discal line ; a broad black postdiscal 



band from C to M-, sharply defined, followed behind M- by a faint postdiscal and 

 a black submarginal line ; distal margin red, exce[)t from M- backwards ; abdominal 

 margin rather brighter red; interspace between black s(]uare patch and brown 

 distal marginal baud M- — SM- also red. lliudwiug below with abdominal area 

 more extended rosy red tiian in vitis. 



S. Tenth tergite pointed. C'lasper densely hairy inside; dorsal margin nearly 

 straiglit ; harpe (PI. XLVIII. f. (i) with two processes as in cacus and adamsi : 

 one pointed, curved, resembling the hook of other species, partly covered by 

 tlie second, which is short, obtuse, compressed, broad. Penis-sheath stout ; process 

 short, triangular (PI. LIV. f 26). 



Larva very dift'erent in adult stage from that of vitis, being particoloured 

 with numerous black ringlets, and, on segments 4 to 11, with narrow obliijue 

 white lateral bauds, extending over two segments. In the young caterpillar the 

 white side-bands are confined to one segment each, and the black transverse lines 

 are rudimentary. — Food-plant : Jussieua. 



Pupa: cremaster rough; labrum somewhat i)rojecting as a small tubercle; 

 head beneath a little more convex than dorsally.
