c?. All the scgiupiits of the fdi'etiivsiis iiavo the second intenuil row of s])ines 

 (Icvelojied iiitt) a many-toothed eomh ; the other rows of spiues are rechic.ed ; the 

 first segment has only the external row inclusive of the numerous additional 

 externo-lateral, irregularly ]ilaced, spines ; the second and fourth rows are indicated 

 hy one or two sjtines ajiically ; the second segment with a few external spines 

 representing row 1, the third segment with still less s])ines, fourth and (ifth 

 segments with ouly the comh, and at a])ex a single spine as a remnant of row 1 ; 

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

 faintly curved. First segmeuts of mid- and hindtarsus as long as the respective 

 tiliia. Tenth abdominal segment similar to tiiat of bici/cr ; tlie sternite much 

 liroader and also shorter. Clasper very large ; its dorso-apical margin strongly 

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

 upwards at end, pointed, sharply dentate along its subventral edge, and alst) 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, sliglitly curved tooth, whicli bears anotlier smaller tooth 

 at the proximal side. 



?. The comb of spines on the foretarsus is not 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 present on all the segments ; 

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

 segment. First segmeuts 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 ; tlicro is 

 a white, generally conspicuous, dash distally of stigma. 



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

 species (chientius, 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 

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

 towards sides. 



JlaL Neotropical Region inclusive of the West Indies. 



Poey, when describing this species, said : " J'ai suivi MM. Latreille et Godart 

 (Enc. m(^th.) dans I'usage de ne point ecrire les noms propres au genitif." 



In the Tring Museum 1 pupa, 130 odd specimens from: Jamaica; Cuba;
