Descriptions of new African LejndojJterct : by A. G. Butler, 

 F.L.S., F.Z.S., &c. 



In the Collection recently brought home by Mr. Monteiro 

 are several new species of Acrcva, Pseudacrma, c&c, which are 

 especially interesting as illustrations of protective assimi- 

 lation, the moths in tb,e Collection are principally 

 interesting from the fact that very many of them are 

 exceedingly closely allied to Indian forms, so much so 

 indeed that an experienced Lepidopterist, upon looking 

 into the box where they were all together, imagined them 

 to be from E. India. 



To the two or three species now described from Mr. 

 Mouteiro's Collection, I have added one or t^^'o, taken by 

 I)u Chaillu in Gaboon.
