260 EHOPALOCEEA. 



We have not seen an example of this species, which was described by M. Mabille 

 from a single female specimen in the Brussels Museum, said to come from Mexico . It 

 is compared with S. oneka (Hewitson).

Pyrrhopyge, auctt. partim. 



Jemadia, Watson, P. Z. S. 1893, p. 14. 



In this genus Mr. Watson includes the species of Pyrrhopyge which are all more or 

 less of a black colour, with hyaline spots on the primaries and blue stripes on the 

 secondaries ; the third median segment of the primaries is very short, not more than a 

 third or even a fourth as long as the second segment ; the subcostal branches are 

 distinct from one another, the second subcostal segment being more than twice as long 

 as the third. The second median branch of the secondaries starts before or at the end 

 of the cell. The posterior tibige have a distinct dorsal crest of hairs. 



The species of this genus much resemble one another externally, and are very 

 difficult to discriminate satisfactorily, but the great diversity of the male genitalia 

 shows that a number of true species exist. The number more or less known to us is 

 about sixteen, and others doubtless exist in collections. Of these, six occur within our 

 limits, Guatemala being the extreme northern range of the genus. 



These six species can be recognized by the following key : — 



a. Two transverse blue bands near the base of the primaries. 



a!. A series of four hyaline spots in the apex of the primaries, two in the 

 disc. 

 a". Spots on the disc united, prothorax spotted above. 



a'". No median band on the secondaries 1- hospita. 



b'"- A median band on the secondaries above 2. hemtsom. 



b". Spots on the disc separated; prothorax with a transverse bluish line,

b\ Five hyaline spots in the apex, one in the disc ; prothorax with a trans- 

 verse bluish line. 

 c" Outer blue band of the secondaries beneath slightly broken up with 



black towards the costa 4. patrobas. 



d". Outer blue band of the secondaries beneath much broken up ... 5. azeta. 

 b. Blue lines at the base of the primaries radiating outwards in the direction

of the nervures 



Owing to the difficulties connected with the nomenclature of the species of this 

 genus, largely increased by Hewitson's frequent practice of describing one specimen and 

 figuring another, often of a different species, we now take the opportunity of figuring 

 all the Central-American species, except J", licinus, with their male genitalia, our names 

 havino- been determined by direct reference to the types in the British Museum.
