;illi('s, ;iiiil lire lioiuolniroiis to tlic similar sjKits of Xi/ccrj/x. The miri'iiw ycllnw 

 band of the biudwiug of aearly even width, sometimes narrowed before luiddie, 

 more or less indicated below on disc as well as before abdominal margin. Fringe 

 of hind wing yellow above, less so below. SC^ and SC'' of forewing not fused at end, 

 SC ending at costal margin a little before apex of wing. 



S- Tenth steruite slender, hooks not strongly curved. Harpe somewhat 

 projecting at cud. Penis-sheath very peculiar (PI. LIV. f. 13): apex of sheath 

 triangularly narrowed, right edge of tliis acuminate part with a row of teeth, ai>ex 

 beset all round with similar teeth, this portion homologous to the whip of the other 

 species ; instead of the spines found at the left side in Seaia tantalus, etc., we find in 

 A', sagra a very long thin process situated at the edge of the mouth of the slieath ; it 

 is a prolongation of the wall of the sheath itself, not a spine-like excrescence, and 

 is accordingly fiat, with one side concave corresponding to the inner surface of the 

 sheath, as is the case with the whip of the other species. This process is homologous 

 with the tubercled ridge found in Nj/cenjx (compare PI. LIV. f. 1 — o) ; it curves 

 in an irregularly raised spiral, and bears about twenty-five rather regularly dis- 

 tributed long branches, which are all situated on the same (external) side and are 

 of nearly the same length. The peculiar organ is generally visible without dissection, 

 jirojecting from the scaling of fan-tail. It is very brittle, breaking off easily close 

 to the sheath. 



?. Vagiual orifice (PI. XLI. f. 1) sliifted jiro.ximad and laterad, lying behind 

 a curved transverse fold.

S. The s])ecies reminds us, in the colour and shape of the forewing, of J'cn'i/o/i/a. 

 l/isca. f. restitiita. Head and thorax without mesial crest. Antenna slender, not at all 

 elid>bed, hook quite gradually narrowed ; end-segment short, conical, less tliiin three 

 times as long as basaliy broad. Underside burnt umber colour, shaded with 

 liluekisii olive ; breast, two series of spots on abdominal sternites (pi'oximal 

 steriiites also more or less the same colour in middle) and vestiges of spots at 

 the lateral edges of the abdominal tergites orange-buff, palpus below nearly the 

 same colour, rather more ochraceous-tawny, bases of wings and abdominal area of 

 hindwing ochraceous-yellow. SC* and St'' of forewing not fused at end, remaining 

 separate as in sagra. 



tS. Tenth sternite with the hook much more suddenly curved than in the other 

 sjjecies. Penis-sheath with a long whip, which bears a number of tubercles, being 

 similar to the whip found in the species of Perigonia and Xijcery.c ; three heavy 

 apical bristles at the right side, preceded by a small number of irregnlarly-placed 

 tubercles ; no spines at the left side. 



Hab. Nicaragua to Bolivia.
