536 BHOPALOCEBA. 



We have seen the type of this distinct species, and we also have a specimen from 

 Taboga agreeing with it. Dr. Staudinger, too, has sent us a male of C. argus labelled as 

 coming from the Argentine Republic. For the genitalia of the male, see Tab. XCVI1I.

Mr. H. H. Smith has sent us two males and two females of this species from Eastern 

 Mexico, Mr. Champion captured a male in Guatemala, and we have also seen a male 

 and a female of it from Chiriqui in Dr. Staudinger's collection. It is not unlike 

 Bhinthon cynea, but is without a brand, and has a sagittate spot between the first and 

 second median branches, instead of a transverse one, on the primaries. The female, 

 as is often the case, and sometimes the male also, has an additional spot near the 

 submedian nervure. The minute subapical spots on the primaries are not always 

 visible on the upperside. A specimen from Atoyac is figured. For the genitalia of 

 the male, see Tab. XCVIII. fig. 24.

Ahs brunneo-fuscis, anticis maculis duabus transversis in linea obliqua, una inter ramos medianos primum et 

 secundum, altera ultra earn, punctisque tribus in linea transversa subapicalibus, interdum valde indis- 

 tinctis, omnibus albo-hyalinis : subtus fere ut supra, marginem internum et externum versus pallidioribus • 

 posticis rubescentioribus, fasciis duabus raacularibus curvatis transeuntibus obscurioribus ; ciliis fulvis. 



2 mari similis, sed maculis majoribus.

 (Champion).— South America to the Argentine Republic. 



Dr. Staudinger has lent us the types of Cobalus cannce, H.-S., and Pamphila osembo, 

 Moschl., the latter being from Surinam 2 , and we are unable to detect any difference 

 between them. He has also lent us a specimen of the same species under the MS. 

 name of Pamphila byzas, Mab., from Venezuela. The absence of the brand, on the 

 primaries of the male separates C. cannce at once from Bhinthon alus, which it closely 

 resembles on the upperside. 



Our series of upwards of thirty examples show some variation in the size of the
