CATASTICTA. 119 



This is the Costa Eican and Panama form of C. nimbice, but more closely allied to 

 C. ockracea than to that species ; it resembles C. ochracea in the extent of the ochre 

 colour of the wings, but the submarginal spots of the secondaries are considerably 

 larger, that between the subcostal nervure and its branch joining the ochre band. The 

 female differs from the same sex of C. ochracea even more than the male, the pale 

 yellow band of the secondaries extending to the base of the wing, and the submarginal 

 spots being very large. 



The sexes of this species appear in Messrs. Butler and Druce's list of Costa-Rican 

 butterflies as C. ochracea and C. nimbice, but it is not evident to which sex the names 

 apply, nor is the question now of any moment. 



Besides Van Patten's specimens, we have several others from Mr. Eogers, but only 

 two from the district of Chiriqui, where the species would appear less common.

Alis fuscis; anticis litura elongata in cellula, altera subtriangulari infra earn (ramis medianis divisa) et 

 maculis apicem propioribus, ochraceis ; posticis dimidio basali (prseter basin ipsam) venis divisa quoque 

 ocbraceis, maculis duabus exterioribus attingentibus aliisque minoribus marginem versus coloris ejusdem : 

 subtus fere ut supra, sed dilutioribus, anticis punctis submargiualibus, maculis duabus cellulas finem 

 propioribus aliisque elongatis in margine ipso, albescentibus ; posticis linea bene angulata ad marginem 

 externum grisea, in margine ipso maculis sex aut septem flavis, aliisque per aream totam diffusis. 



2 mari similis, sed colore alarum ochraceo magis restricto et flavescentiore, alis subtus omnino pallidioribus. 



Hab. Costa Rica ( Van Patten l ), Irazu (Bogers) ; Panama, Chiriqui (Arce). 



This species was described by Messrs. Butler and Druce from a single male example 

 which formed part of Van Patten's Costa-Rican collection. We have since received 

 others of both sexes from the same country from Mr. Rogers. In the neighbourhood 

 of Chiriqui it appears to be a common species, as a good series of examples have been 

 sent us from that country. 



We have figured a specimen from Chiriqui.
