We have two specimens, male and female, from Nicaragua, and two males from 

 Colombia, which agree fairly with Mr. Butler's type of this species. 



P. nyctineme is a close ally of P. macareus, but seems to be distinguishable externally 

 by the slight difference indicated above. The male genitalia are very distinct from 

 those of P. macareus and P. tiphys, as an examination of the figures will show. (See 

 Tab. LXXXIII. fig. 12.) 



4. Pellicia bromias. (Tab. lxxxiii. figg. 13, 14 4 , 15 $ .)

This species may be recognized without much difficulty from the other Central- 

 American members of Pellicia by the arrangement of the dark bands on the primaries, 

 the two outer ones being confluent below the cell. 



It is a common species in Southern Mexico, spreading into the Pacific coast region of 

 Guatemala. 



We have experienced some difficulty with the dissections of the male genitalia of 

 this species, as in the five specimens we have examined they are not so much alike as is 

 usually the case with these organs. There are no tangible external characters justifying 

 any separation of our series into two or more species ; and as the male genitalia examined 

 tend to show that the more diverse forms are connected by intermediate ones, we are 

 driven to the conclusion that these parts in this particular species are more variable 

 than usual. (See Tab. LXXXIII. fig. 14.)
