412 RHOPALOCEBA. 



Hob. Mexico, Acaguizotla, Kincon, Rio Papagaio, La Venta, Tierra Colorada, Dos 

 Arroyos, Venta de Zopilote (H. H. Smith), Cuernavaca (mus. Felder \ II. II. Smith). 



This species, of which we have a good series of male specimens from Western 

 Mexico captured by Mr. Herbert Smith, may readily be distinguished from S. erosa 

 by the much more conspicuous bands on the upper surface of the wings ; on the 

 primaries beneath there are no lilac spots below the first median branch. In the 

 outline of the wings the two species are much alike, but S. funebris has the tooth at 

 the apical angle of the wings not quite so prominent. 



The primaries have a costal fold as in S. erosa, but the male genitalia are almost 

 exactly like those of S. corrosa, which, again, has no costal fold. 



Felder's type came from Cuernavaca 1 , whence Mr. Smith sent us a specimen. 



The male genitalia have a forked tegumen ; each branch is humped on the dorsal 

 edge, and ends in an abrupt hook ; the harpes have a deep fissure on the dorsal 

 edge, from the bottom of which a rod proceeds, which is first projected back and 

 then turns abruptly and is carried beyond the rounded end of the harpe. (See 

 Tab. LXXXVII. fig. 19.)

M. Mabille's type of this species came from Cayenne, but we have no specimens 

 from that country. Our series is named from an example from Chiriqui lent us by 

 Dr. Staudinger, determined by M. Mabille to be his Antigonus corrosus. 



The species is very like S. funebris, but has the dark band of the primaries very 

 distinct, while those of the secondaries are abbreviated and do not cross the wing. 

 The primaries of the male have no costal fold, so that the two species are readily 

 distinguished. 



The range of S. corrosa is much more extended than that of S. funebris. Com- 

 mencing in Eastern Mexico, in the State of Vera Cruz, it is found throughout Central 

 America as far as Panama, and also in South America. 



The male genitalia are almost exactly like those of 8. funebris.
