42. Nipteria occulta A\'arr. 



The ? of this insect, a specimen of which I have seen from Santo Domingo, 

 S.E. Pern, diSers somewhat from the c?. The markings of the npperside are much 

 less distinct ; the two abbreviated apical lines are hardly visible, and the cell-sj)ots 

 almost absent. On the underside the fulvous triangular space at apex of forewing 

 is more conspicuous than in the t? ; while in the hindwing the dark transverse line 

 is followed by a fulvous ochreons area. 



The ?, which is the same size as the <?, was taken in December 1002, wet 

 season (Ockenden).
