($. All the segments of the foretarsiis have the second internal row of spines 

 developed into a manj'-toothed ('oml) ; the otlier rows of spines are reduced ; the 

 tirst segment has only the external row inelnsive of the nnmerons additional 

 externo-lateral, irregularly jilaced, spines : the spcimd and fourtli rows are indieatod 

 by one or two spines apically ; the second segment with a few externnl spines 

 representing row 1, tlie third segment with still less spines, fourth and lifth 

 segments with only the comb, and at ajiex a single sjiinc as a remnant of row 1 ; 

 first segment very much shorter than tibia, little longer than the second, very 

 faintly curved. First segments of raid- and hindtarsus as long as the respective 

 tibia. Tenth abdominal segment similar to that of Incifcr ; the ^sternite much 

 broader and also shorter. (Uasper very large; its dorso-apical margin strongly 

 curved inwards ; liarpe an elongate triangular process (PI. XXXVII. f. 5) curved 

 upwards at end, pointed, sharply dentate along its subventral edge, and also at 

 the upper edge near apex ; a large tuft of long and strong bristles at the upper 

 edge near the base of the process. Penis-sheath (PI. XIX. f. 14) armed at end 

 with a long, horizontal, slightly curved tooth, which bears another smaller tooth 

 at the proximal side. 



?. The comb of spines on the foretarsus is nut well marked, the spines of the 

 second internal row being directed distad, as in the case of an ordinary tarsus ; 

 but these spines are rather close together, and the comb-like arrangement becomes 

 more apparent on the distal segments ; all four rows ])resent on all the segments ; 

 first segment almost as long as the tibia, nearly twice the length of the second 

 segment. First segments of mid- and hindtarsus about 1 i mm. longer than the 

 respective tibia. Vaginal plate broad, the slanting lateral edges somewhat recurved 

 (PI. XIX. f. 6), forming a low ridge; mouth of vagina beyond middle, armed 

 proximally at each side with a triangular flat lobe, the apex of which is more or 

 less rounded. The forewing is rather prominently marked with white ; there is 

 a white, generally conspicuous, dash distally of stigma. 



Larva not known. Pnpa : tongue-sheath much shorter than in the other 

 species {cluenlius, antaeus), only 12 mm. long from the base in a straight line to 

 the end, ringed as in antaeus, the underside smooth ; abdominal patches as in 

 clventim, eighth segment without one, all the patches narrower in middle than 

 towards sides.
