PYEBHOPYGE. ' 247 



a narrow white transverse band near the base of the secondaries, the primaries being 

 black throughout. In the allied forms, P.fluminis, Butl., and P. latifascia, Butl., this 

 band spreads to the base of the primaries and is usually much wider. The character 

 is, however, decidedly variable, and it is even doubtful if there is really more than one 

 species of this form. 



P. phidias seems to be common in the State of Panama, but we have no evidence of 

 its occurrence in any other part of Central America. On the southern continent its 

 range is very extensive. 



The male genitalia have a great general resemblance to those of P. hypericin the type 

 of the genus Pyrrhopyge. The anterior portion of the harpes is not so produced, 

 and the bristles near the angle of the ventral edge are not so strong. (See Tab. 

 LXXIII. fig. 4.)

Hab. Mexico, Coatepec and Kinconada (Schaus), Cordova (Rumeli), Atoyac (H. H.

This orange-red-headed species, with its dark wing-coverts, seems most nearly allied 

 to P. charybdis, Westw., both species having dark and not red coxae to the anterior 

 legs. P. zeleucus (Fabr.) is also allied, but the coxse in that species are red *. 



From P. charybdis, P. zenodorus can readily be distinguished by the more orange 

 tint of the head and the extremity of the abdomen. Its range is general through the 

 eastern portions of our country, from the middle of the State of Vera Cruz to Costa 

 Eicaf. It appears again in Eastern Peru, but we have not yet met with it in any 

 collection from the intervening countries. In Mexico and Eastern Guatemala it occurs 

 in the hotter regions, but ascends the mountains to an elevation of 4000 feet near 

 Coatepec. We never found it in the lowlands of Guatemala bordering the Pacific Ocean. 



The genitalia of the male of P. zenodorus resemble those of P. phidias, the two 



* We follow M. Mabille in applying Fabricius's name to this species, and Mr. Watson does the same. 

 Plotz, however, as well as Hopffer transpose the names zeleucus and charybdis, ascribing black anterior coxa? 

 to the former and red ones to the latter. The type of P. charybdis, now in the ritish Museum, proves that 

 they are certainly wrong in the latter case. 



t The only Pyrrhopyge of this form represented in Van Patten's collection belongs to this species ; we 

 therefore infer that it was misnamed P. thasus * in Messrs. Butler and Druce's List. P. thasus, Cr M is a very 

 •distinct species, and even, as now appears, belongs to a distinct genus, Mysoria,
