b. *Oell of forewing less than two-thirds the length of costa. 

 a 1 . Antennas, tip acuminate. 



a 2 . Terminal joint of palpi suberect. 



a 3 . Second median branch of forewing arising far 

 before end of cell, hardly twice as far from base 

 of wing as from end of cell. 



Charmion, de Niceville. 

 b 3 . Second median branch of forewing arising shortly 

 before end of cell, more than three times as far 

 from base of wing as from end of cell. 



Cel^enorrhtnus, Hiibner. 

 6 s . Terminal joint of palpi horizontally porrected. 

 a^ Apex of forewing not truncate. 



a 4 . Lower margin of cell of forewing not strongly 

 arched between first and second median 

 branches. 

 a 5 . Hindwing, outer margin sinuate. 



a 6 . Hindwing, hardly or not at all elongate ; 

 hind tibiae of male with a tuft of hair attach- 

 ed to proximal end. 

 a 7 . First subcostal branch of hind wing shorter 

 than first median branch. 

 a 8 . Lower margin of cell slightly arched 

 between first and second median ner- 

 vines. 



Sarangesa, Moore. 



b s . Lower margin of cell straight between 



first and second median nervules. 



Coladenia, Moore. 



V. First subcostal branch of hindwing as 



long as or longer than first median 



branch. 



Daimio, Murray. 



* In measuring these distances, the length of the cell should be taken from the bifurcation 

 of the median and subcostal nervures to the extreme apex of the cell, which in nearly every 

 genus is at the origin of the fifth subcostal branch ; the length of the costa should be taken in 

 a straight line from the base of the costa, where it joins the thorax, to the extreme apex of the 

 ■whig, which is situated practically at the extremity of the fourth subcostal branch. In re- 

 ferring above to the fifth subcostal branch, it would perhaps be more correct to say "terminal 

 portion of subcostal nervure."
