PIEEIS. 135 



We have figured a male from Costa Rica and a female from Calobre in the State of 

 Panama. 



9. Pieris josepha. 



Pieris josepha, Salv. & Godm. Ann. Mag. Nat. Hist. ser. 4, ii. p. 150 \ 

 Pieris josephina, Butl. & Druce, P.Z. S. 1874, p. 361 (nee Hubner) \ 



Alls cretaceo-albis, anticis macula ad cellulae finem fusco-nigra: subtus fere ut supra, anticis costa anguste, apice et 

 posticis omnino ochraceo lavatis ; posticis quoque macula indistincta fusca ad celluhe finem, costa aurantia. 



2 alis ochracescentioribus ; anticis macula ad cellulae finem, duabus ultra earn, una in vena mediana, altera infra 

 earn, tertia supra venam submedianam aliisque elongatis ad marginem externum fuscis ; posticis venis mar- 

 gmem externum versus indistincte fusco notatis : subtus anticis maculis omnibus (prater ea ad cellule 

 finem) minus distinctis.

Though we have separated F. josepha from F. josephina, that is, the continental from 

 the Antillean form of this species, the difference between the two is slight. The outer 

 margin of the secondaries of P. josepha is less prominently rounded in both sexes; 

 moreover, the male has no indication of any spot at the end of the cell of the secondaries, 

 and that on the primaries is distinctly smaller. These slight differences are of more 

 value as they distinguish an island from a continental form. P. josepha belongs exclu- 

 sively to our country, and its range extends from Southern Mexico to Costa Eica, but is 

 everywhere rare. In South America P. bunice takes its place, a species readily distin- 

 guished by the black apex to the wings.

Ahs anticis ad apicem elongatis margaritaceo-albis, costa et margine externo angustissime fusco limbatis : 

 subtus fere ut supra, sed posticis ochraceo tinctis, et ad costse basin flavo notatis. 



2 alis anticis sordide albis, costa late (nisi in medio) et apice cum margine externo pallide fuscis introrsum 

 irregulariter sinuatis ; posticis ochracescentioribus, margine externo fuscis : subtus sordide margaritaceo- 

 albis, colore fusco paginae superioris vix indicate, anticis macula fere obsoleta in margine externo pallide 

 fusca, ad basin flavescentibus.
