similar structure in P. menecrates, and it proves that the two species are well 

 denned and isolated. 



4. P. jonas section. Apex of the abdomen fulvous.

Alis cyaneo-nigris unicoloribus, ciliis albis ; posticis margine externo sensirn denticulato ; capite nigro, fronte

Felder's description 1 as well as that of Hopffer 2 were both based upon specimens 

 from Mexico said to be females. Mr. Druce's type of P. cydonia, which we now figure, 

 is probably of the same sex, the outer margin of the secondaries being much rounded 

 and slightly dentate. 



This species is only known to us from a single example from each of the localities 

 mentioned above, all of which lie upon the eastern side of the mountains of Central 

 America, at an elevation of about 3000 feet. 



Mr. Champion's specimen is a male, and resembles Mr. Druce's type. The geni- 

 talia differ considerably from those of more typical Pyrrhopyge, as the figure shows 

 (Tab. LXXIII. fig. 8). We have not yet met with a similar structure in any other 

 member of the genus. 



5. P. chalybea section. Wings edged with fulvous, apex like the rest of 

 the abdomen, not red or orange.

Hewitson's original description of P. zereda was based upon an example said to have 

 come from Ecuador, but he afterwards figured a Mexican specimen 1 , mentioning at the 

 same time that it was represented by specimens in Saunders's collection: these latter 

 are now in our possession. On an examination of the Hewitson collection we find 

 that the name P. zereda was applied to a species allied to P. hygieia, Feld., which we
