tibiae blackish ; hiiidtibiii of 6 louger than, of ¥ as long us, the tirst tarsal 

 segment : siJiirs longer thau in the other species of Clanis, the short ones over 

 half the length of the long ones, those of the apical pair of the hindtibia not so 

 widely different in length as in the other Clanis, the longer one more than half 

 the length of the _lirst tarsal segment. Wings more elongate than in any other 

 species of this genus. Distal margin of forewing in S longer, in ? very little 

 shorter, than the inner margin ; the lines of lunules of the forewing on the whole 

 stronger marked than in bilineata, with which the species has been confounded 

 by Leech and Hampson ; there are in some specimens four such lines between the 

 cell and the postdiscal line which begins at the apical patch ; the black area of 

 the hindwing is more extended than in bilineata. 



6. The tenth tergite (PI. XXIV. f. 3) is sinuate at the end, the lobes 

 curved downwards and pointed, with the edges irregularly notched ; in a lateral 

 view (PI. XXIII. f. 2~) tlie lobe appears rather dilated before the apex, convex. 

 The sternite (PI. XXIV. f. 3) is membranaceous laterally, the mesial lobe is sub- 

 truncate, trapeziform, with the edges somewhat rounded. The liarpe (PI. XXXII. f. 8) 

 consists of a submesial ridge cm, which is deeply curved twice and distally raised 

 to a flattened process, which curves basad and somewhat resembles the process 

 of titau ; the dorsal process pd is short and broad, and beset with rough warts, 

 whicli bear each a short bristle. 



?. The eighth tergite (PI. XVI. f. 8) is short, broadly sinuate, the sinus 

 rounded, the sides projecting, rounded. The vaginal orilice (PI. XVI. f. 9) is 

 surrounded by two folds ; the postvaginal plate is broadly rounded.

The sjiecies is generally larger thau bilineata, but it varies in siiie ; it is easily 

 distinguishable from bilineata by the longer wings and the black midtibia and long 

 spurs, besides tlie structure of the end of the abdomen.

6 ?. The tyjie of this species is a ? which has only one leg lefc out of the 

 six, and this i> a foreleg without tarsus. The specimen agrees in the shape of 

 the eighth abdominal tergite well with andidosa, not at all with bilineata : the 

 vaginal ])late we have not dissected out, for fear of breaking the rather old and 

 brittle specimen. In colour the individual comes very near tindtdosa,, ditiers, 

 however, in the following points : the forewing, which is much less elongate than 

 in undulosa, bears three sharply marked dentate lines on the disc, equidistant from 

 each other and from cell and the postdiscal, indistinct, line which begins at the
