it, although the single specimen does not allow a thorough examination 

 of the venation. It is a splendid, shining little insect, which "ought" 

 to go in the genus Eucosmophora (who carries a beautiful ornament). 

 It seems very near E. dives Walsingham, but there is no trace of any 

 white costal spot, nor any white at all on the forewing, as is the case 

 with E. divefi. 



The larva is cylindrical, with 14 legs, yellow, with darker yellow 

 head and brown mandibles. It mines the upper sid(^ of young leaves 

 of Sideroxvlon, at the same time drawing the leaf longitudinally into 

 a roll or fold, which covers up tlie mine out of sight.
