PYEKHOPYGE. 251 



subsequently described as P. rufipectus (P. Z. S. 1879, p. 152). Why Hewitson 

 shifted his name to the Mexican insect is not apparent. The latter must now bear 

 Mr. Scudder's title *. 



P. chalybea is strictly confined to Western Mexico. Mr. Forrer secured specimens 

 nearMazatlan, and at Ventanas in the mountains lying between that city and Durango, 

 and Mr. Schumann captured a number of individuals near Guadalajara in the month 

 of July. 



The harpagones are not quite symmetrical in this species, the left side having a 

 thickened dorsal edge besides the central projecting lobe. The cedeagus is of very 

 peculiar form. (See Tab. LXXIII. fig. 12.) 



6. P. ^esculapius section. Wings brilliant steel-blue ; apex like the rest of 



the abdomen. 



9. Pyrrhopyge aesculapius. (Tab. LXXIII. fig. 9c?.)

 Pyrrhopyga variegaticeps, Godm. & Salv. P. Z. S. 1879, p. 152 3 . 



Alis nitide cyaneis ; posticis ad marginem externum saturatioribus, margine ipso rufo ; corpore nigro ; capite 

 inter oculos fasciolis indistinetis tribus albis, palpis nigris ; coxis anterioribus nigris. 



Hab. Costa Rica 2 , Rio Sucio (Rogers 3 ) ; Panama, Chiriqui (Ribbe, in mus. Standing w 12 ), 

 Volcan de Chiriqui (Champion). 



Dr. Staudinger has lent us the type of his P. aesculapius, and we find it agrees 

 precisely with those of our P. variegaticeps. The species is allied to P. hygieia, 

 Felder, but differs in the white markings of the head, the palpi being black instead of 

 red, and in having the rufous of the outer border of the secondaries confined to the 

 fringe. The anterior coxse are black, and not red as in P. rufipectus and P. rufinucha. 



Rogers obtained several specimens of this species when collecting on the Rio Sucio 

 in Costa Rica. Mr. Champion's specimens were taken at an elevation of between 3000 

 and 4000 feet on the Volcano of Chiriqui. Ribbe, who first discovered it at Chiriqui, 

 says that it is not common there 1 . 



10. Pyrrhopyge creon. (Tab. LXXIII. figg. 10, 11 j .)

* In his original description Hewitson states that the type of P. zereda is in his own collection ; but, in his 

 ' Equatorial Lepidoptera,' p. 69, he says that he took his description of this insect from a specimen in the 

 collection of Mr. Bates. The point is of no consequence, as both types (one of which is in the British Museum, 

 the other in our possession) belong to one species.
