Genus ODONTOPTILUM, nov. 



Forewing, elongated ; costa gently arched ; apex acute ; outer margin 

 at first at right angles to the costa, then directed strongly obliquely 

 inwardly ; inner angle rather acute, inner margin short, sinuous, of 

 about the same length as the outer margin ; costal nervure not reach- 

 ing to opposite the apex of the discoidal cell ; all four subcostal ner- 

 mles with their bases about equally distant one from the other; the 

 fourth subcostal reaching the apex of the wing ; the terminal portion 

 of the subcostal nervure ending on the outer margin considerably 

 below the apex of the wing ; upper disco-cellular nervule stout, 

 straight, short, outwardly oblique ; middle disco-cellular shorter than 

 lower ; lower disco-cellular straight, in the same straight line as the 

 middle, both strongly inwardly oblique ; median nervules arising very 

 far apart, second median arising long before the lower end of the cell ; 

 first median arising one-third of the length of the cell from the base of 

 the wing ; submedian nervure sinuous ; internal nervure short and 

 running into the submedian nervure, both as usual. Hindwing, costa 

 short, much produced at base, then straight to apex ; outer margin 

 strongly excavated between terminal points of costal nervure and 

 first subcostal nervule, then arched to anal angle ;. anal angle slightly 

 produced lobe- wise ; inner margin sinuous; costal nervure gently arched, 

 ending at apex of wing ; first subcostal nervule arising some distance 

 before the apex of the discoidal cell ; upper disco-cellular nervous 

 straight, slightly outwardly oblique, in the same straight line as the 

 lower ; lower disco-cellular longer than the upper ; discoidal 'nervule fine 

 but quite distinct ; second median nervule given off just before the 

 lower end of the cell ; first median given off slightly nearer to the 

 lower end of the cell than to the base of the wing; mbmedkm and 

 internal ner aires straight, Antennae, less than half as long as the costa
