12. GeUUS PVTHONIDES. 



Pythonides, Hiibn. Verz. p. Ill (1816). Type, cerialis. Cram. 



AntenncC : club moderate, more or less curved, but not hooked. 

 Palpi porrect ; third joint short, bluntly conical. Fore wing ; inner 

 margin considerably longer than outer margin ; costain some species 

 very strongly arched ; outer margin sHghtly excavated just above 

 outer angle ; cell less than two-thirds the length of costa ; vein 12 

 reaching costa before the end of cell ; discocellulars erect, the lower 

 the longer ; vein 3 shortly before the end of cell ; vein 2 hardly 

 nearer to base of wing than to end of cell. Hind wing : outer 

 margin evenly rounded ; discocellulars and vein 5 barely traceable ; 

 vein 3 immediately before tlie end of cell ; vein 2 twice as far from 

 base of wing as from end of cell. No costal fold in male. 



This genus can be divided into two groups on the characters of 

 the hind tibite. 



A. Two pairs of spurs on hind tibise, no tuft of hairs in male.

Nisoniades, Hiibn. A^erz. p. 108 (1816j. Type, bromius, StoU. 



Antennae : club slender, evenly curved. Third joint of palpi 

 minute, bluntly conical. Fore wing : costa straight, apex rather 

 acute : inner margin considerably longer than outer margin ; cell of 

 fore wing less than two-thirds the length of costa ; vein 12 reaching 

 costa almost opposite the end of cell ; discocellulars slightly 

 inwardly oblique ; vein 3 shortly before end of cell, more than 

 three times as far from 2 as from 4 ; vein 2 more than twice as 

 far from end of cell as from base of wing. Hind wing evenly 

 rounded ; vein 7 close to end of cell ; discocellulars and vein .5 

 barely traceable ; vein 3 immediately before end of cell ; vein 2 

 slightly nearer to end of cell than to base of wing. Hind tibite 



fringed, and with two pairs of spurs.
