momonana than in walkerana. This and the pattern difference given 

 in the ke}^ are the only characters separating the two, except the 

 marked difference in food plant and distribution. In one of the 

 specimens in the National Collection (a female) I find the white dash 

 in cilia below apex missing. It is present and conspicuous in the 

 other specimens, however, and I therefore am compelled to list the 

 species twice in the key.

 lection ; there are also in the American Museum four specimens with- 

 out locality label, one of which had been identified by "Walsingham 

 and all of which Kearfott had labeled " Types " (without warrant, 

 since the rest of Walsingham's type material is in the British Mu- 

 seum).
