 On the under side the markings are much as in I), catalla, but

This is a smaller insect than D. catalla., a long series of which; 

 together with D. aucta Karsch * were obtained by Mr. Bates at 

 Bitje. Good photographs of Karsch's types in the Berlin 

 Museum have enabled me to identify these species with 

 certainty.

 angle ; apical third of fore wing and veins of hind wing black.

The absence of all lines on the under side at once distinguishes 

 this insect from its allies. 



Pseudaletis batesi, sp. n. (Plate XXXV. fig. 6, § .)

 outer margin ..broadly blackish brown; costal margin narrowly

 another, like it, closing the cell. The basal, cellular, and
