Zeller described his leucatea from Brazil and St. Thoma.s. Later ^ 

 he recorded it from Puerto Eico, Mexico, and Panama. I omit the 

 latter reference from the synon3any, as it is quite likely that he had a 

 mixed series before him. Until genitalia of all his paratypes are 

 examined we can be sure only of his West Indian specimens and the 

 actual type. Mr. Tams has examined the genitalia of the latter and 

 checked them with my figures. I am indebted to him for the iden- 

 tifications. As far as we know there is only one pure white species 

 of Rupela found in the Antilles; therefore longkomk Mo.schler is 

 presumably the same as leucatea. 



Male. — ^Wings shining white. Fore wing with veins 11 and 12 sep- 

 arate ; 4 and 5 connate or shortly stalked. Hind wing with 4 and 5 

 connate or stalked. Anal tuft white.

 eral arms; in ventral aspect with basal half rounded (central part 

 of lower margin convex) ; apical half tapering to blunt point; apex 

 not appreciably upturned; inner surface near apex finely scobinate. 

 LTncus stout ; basal portion broad with moderately wide dorsal 

 groove; laterally compressed on dorsum at apex; from side view,
