THECLA.— THECLOPSIS. 99 



is represented in our collection by a single male specimen taken by Mr. Bates in the 

 valley of the Upper Amazons, but which has remained undescribed until now *. Of 

 the other Dr. Staudinger has just sent us a single female specimen from Chiriqui, which 

 we here describe as T. insignis. 



These three species will probably be separated generically from Thecla proper when- 

 ever the subdivision of the genus can be satisfactorily undertaken. Before this can be 

 done, specimens must be properly dissected and their structure accurately examined. 



Thecla insignis, sp. n. 



$ alis fuscis unicoloribus : subtus anticis fuscis, plaga apicali tripartita flavida, macula ad basin costae aurantia ; 



posticis flavidis venis latis fuscis divisis, plaga magna ad angulum apicalem altera ad fines ramorum 



medianorum fuscis, plaga magna ad basin aurantia. 

 <$ adhuc ignotus. 



Hab. Panama, Chiriqui (Trotsch). 



Dr. Staudinger has just sent us, in time for the insertion of its description here, a 

 female of this curious Thecla which is allied to T schausi and T. miranda. 



B. Front legs of male with a complete five-jointed tarsus and with claws. 



THECLOPSIS, gen. nov. 



The insects we include in this genus have all the appearance of Thecla; but in 

 preparing a male specimen of Thecla lebena of Hewitson, we found that not only is the 

 cell of the primaries of peculiar form, but the front legs are unlike those of any Thecla, 

 and indeed of any member of the Lycsenidse which we have examined. Taking T. lebena 

 as the type of our new genus Theclopsis, we find that two species of our region, viz. 

 T. demea (Hew.) and one now described as T. emus, have the cell of the primaries 

 formed exactly as in T. lebena ; but we have not been able, for want of specimens, to 

 examine the front legs, so we include both species in this genus from the structure of 

 the cell alone. 



T. lebena has, as in all the American Thecla?, two subcostal branches, both emitted 

 from the subcostal widely apart, and the second some way before the end of the cell. 



* Thecla miranda, sp. n. 



T. schmisi aflinis, ejusdem forma angulo posticarum anali magis prominente, alis supra magis purpurascentibus : 

 subtus plaga lactescenti-alba ad anticarum apicem; posticis macula magna trifida subapicali ejusdem 

 coloris, cellula ad basin et margine interno eodem modo picturatis : abdomine subtus albo.
