THECLA. 83 



We have two examples of this species before us, both of them females, which are so 

 different from our other specimens of that sex of species of the T. badeta group, that 

 we have thought it necessary to describe them, though we have some doubts as to 

 their ultimate status, which cannot be determined till a larger series has been examined, 

 and males of all these closely allied forms obtained. 



172. Thecla lampetia, sp. n. 



T. gabince quoque similis, sed alis anticis cellula ad basin et infra earn ad angulum analem et posticis dimidio 

 margini interno proximo nitide cseruleis : subtus linea discali magis nigricante, maculis rubris submargi- 

 nalibus introrsum nigro limbatis, margine ipso fere omnino nigro infcrorsum albo marginato. 



Hab. Costa Rica, Cache (Bogers). 



We have a single female specimen which does not agree with the female of either 

 of the preceding species. All these three species are allied to T. badeta of Hewitson, 

 of which we have one of the types, but they all have more or less purple or blue on 

 the upper surface of the wings, those of T. badeta being of a uniform brown, and there 

 are other differences on the underside making it improbable that they all belong to 

 one variable species.

173. Thecla milto, sp. n. (Tab. LVII. figg. 22, 23 $ .) 



$ alis fuscis ad basin vix cserulescentibus ; posticis area interna squamis cseruleis frequenter aspersis : subtus 

 gilvis, linea communi discali introrsum fusca extrorsum alba in posticis inter venas regulariter fracta, 

 fascia lata submarginali alba ad angulos analem et apicalem introrsum late rubra in medio fusca, margine 

 ipso fusco introrsum albo anguste marginato, ciliis albidis, lobulo anali et macula inter ramos medianos 

 nigris. 



S nobis ignotus. 



Hob. Panama, Chiriqui (Trbtsch). 



Dr. Staudinger has lent us the only specimen of this species that we have seen — a 

 female from the district of Chiriqui, which we figure. It is manifestly allied to 

 T. teucria of the Amazons valley, from which, however, it differs in the upperside 

 being tinged with blue, the secondaries being sprinkled with pale-blue scales ; beneath, 

 the band common to both wings is nearer to the margin and much less strongly 

 impressed on the primaries. 



30. T. cerata section. 



174. Thecla cerata. 



Thecla cerata, Hew. 111. Diurn. Lep. p. 191, t. 76. ff. 607, 608 \ 



Alis plumbeo-cseruleis ; anticis costa et marginibus externis angustisime nigris, ciliis fuscis : subtus glauco- 

 fuscis, linea communi discali nigra extrorsum albo limbata ad venam medianam fracta deinde ad marginem 

 internum profunde lunulata et introrsum rufo limbata, linea altera nigra ultra earn quoque lunulata ad 

 venam medianam, extra earn inter ramos medianos ruberrimis, punctis duobus submarginalibus nigris, 

 lobulo anali nigro introrsum linea rubra juxta eum nigra albo atomata, margine externo nigro introrsum 

 albo limbato.
