34. Thecla perpenna, sp. n. (Tab. LI. figg. 3, 4c?.) 



c? T. husce similis, sed minor et anticis parte apicali multo latius fusca, plaga sericea multo minor et macula

Eab. Panama, Chiriqui {Bibbe). 



The single male specimen upon which our characters are based and our figure drawn 

 was lent us by Dr. Staudinger, for whom it was obtained by Herr Eibbe during his 

 expedition to Chiriqui. It is unquestionably distinct from T. busa on the one hand, and 

 T. undulata on the other, though obviously allied to these species. 



35. Thecla hyas, sp. n. (Tab. LI. figg. 5 2 , 6, 7 c? .)

Thecla tolmides, Hew. 111. Diurn. Lep. p. 80 2 (nee Feld.). 



S alis nitide viridi-CEeruleis, marginibus externis anguste fuscis, anticis plaga sericea nulla, posticis lineola ad 



angulum analem nulla ; subtus obscure castaneis, lineis duabus transversis albis extus albo atomatis. 

 $ alis fuscis, dimidio basali tantum viridi-cseruleis, aliter mari similis. 



Eab. Mexico (Mus. Brit. 2 )-, Guatemala, Vera Paz {Hague); Costa Eica (Van 

 Patten *) ; Panama, Chiriqui (Bibbe). 



T. hyas bears a strong resemblance to T. tolmides of Felder, from Colombia, of which, 

 no doubt, it is a more northern form. The male differs in having a much narrower 

 dark outer border to the wings, and in the general colour beneath being of a chestnut 

 rather than a dark brown ; the lines, too, on the under surface are much less strongly 

 impressed. Though of wide range in Central America, it is nowhere common, but 

 perhaps more so in Costa Eica than elsewhere, Van Patten having sent several 

 examples from that country, a male and a female of which we have figured. 



2. No alar stigma; costa and outer margin of primaries much rounded; two secondary 

 filaments ; wings beneath rufous ; primaries crossed by three transverse white 

 bands. (Species 36, 37.) 



36. Thecla cadmus. (Tab. LI. figg. 8, 9 <? , 10 $ .)

Alis supra purpureo-cyaneis, marginibus externis latis et anticarum costa et apice nigricantibus : subtus rufo- 

 brunneis, lineis tribus valde irregularibus glauco-albidis transfasciatis, una per cellulas, altera ultra eas, 

 tertia discali margini externo plus minusve parallela, in posticis duplici; posticis maculis tribus ad 

 augulum analem nigris castaneo introrsum cinctis.

T. cadmus has a wide range in South America, extending from Bolivia in the south
