208 KHOPALOCEKA. 



Mexico in the British Museum under the title it now bears ; but he gave no description 

 of it, and it was not until 1864 that Mr. Bates supplied this deficiency, and characterized 

 specimens obtained by us in the interior of Guatemala 2 . The range of P. belesis is 

 almost exactly that of P. branchus, but as yet it has not been recorded south of 

 Nicaragua. In Mexico and Guatemala it is a species of the eastern side of the main 

 mountain range, and is absent from the country bordering on the Pacific Ocean.

P. belesi similis, sed anticis macula albida bifida aut trifida medialiter notatis ; posticis maculis submarginalibus 

 rubris omnino ut in specie notata. 



Hab. Mexico (Salle l ) ; Guatemala (mus. Stand.) ; Hondukas (mus. Stand.). 



We know very little of this species, as we do not possess any specimens, and the only 

 ones we have as yet seen are three kindly lent us by Dr. Staudinger from Guatemala 

 and Honduras. One of the latter is rather aberrant, the spots on the primaries being 

 only faintly indicated, and those on the secondaries are a little more elongated than in 

 the other examples. This specimen, therefore, is somewhat intermediate between 

 P. hephmstion and P. belesis, with a slight divergence towards P. branchus itself. 



29. Papilio belephantes, sp. n. (Tab. lxvii. fig. 6c?.) 



P. brancho et P. belesi similis, ab illo anticis immaculatis, ab hoc fascia posticarum latiore differt. 



Hab. Mexico, Atoyac (H. H. Smith) ; Guatemala (v. Turckheim), Polochic valley 

 (F. D. G.& 0. S.); Honduras (mus. Stand.). 



We have seen four specimens of this butterfly, which, though closely allied to both 

 P. branchus and P. belesis, appears to be distinct from either, and also from P. hephce- 

 stion. The primaries are spotless as in P, belesis, but the secondaries have a scarlet 

 band of the same width and position as in P. branchus. 



Our two specimens from Atoyac and the Polochic valley are both females, but another 

 submitted to us by Dr. Staudinger from von Turckheim's collection is a male, and the 

 fourth from Honduras is also of that sex. We thus see that the sexes in this species, 

 as in its close allies, are similarly coloured.
