specimen, and that the male of T. paphlagon remains to be discovered. Both these 

 species have a general resemblance to the well-known T. pelion of Cramer, but the 

 structure of the brand of the primaries of the males differs essentially, so that the 

 apparent similarity may not indicate any close relationship. 



c 6 . No alar stigma, but a pencil of hairs on the subcostal nervure of the secondaries 

 above; costa of secondaries normal ; a single marginal filament. (Species 101, 102.) 



101. Thecla pion, sp. n. (Tab. LIV. figg. 28, 28 a, 29 s , 30 2 .) 



Alis obscure fuscis, anticis infra cellulam ad marginem internum et posticis (prseter apieem) obscure cyaneis ; 

 posticis vena mediana penicillata : subtus fuscis, linea communi discali fusca, in posticis fracta et extrorsum 

 albo marginata, posticis quoque linea submarginali indistincta fusca, lobulo anali nigro, introrsum albo et 

 rubro anguste marginato, macula juxta eum nigra caeruleo atomata, macula quoque inter ramos medianos 

 rubra puncto nigro instructa. 



2 mari similis, sed alarum colore cseruleo multo magis pallido, vena mediana posticarum haud penicillata : 

 subtus omnino pallidioribus, lineis magis distinctis. 



Sab. Guatemala, Polochic valley, Dueiias (F. D. G. & 0. S.), Calderas {Champion); 

 Panama, Chiriqui (Trbtsch). 



A species readily recognized in the male by the small tuft of hair on the median 

 nervure of the secondaries, which is placed on the costal side of the nervure instead of 

 the median, as in T. oppia. 



We have a good series of specimens from Guatemala, and have figured a male from 

 Dueiias and a female from Calderas. The only Panama example before us is a female 

 lent us by Dr. Staudinger. 



102. Thecla oppia, sp. n. (Tab. LV. figg. 1, 2c?.) 



Ahs purpureis ; anticis costa et margine externo nigris ; posticis costa et margine nigris, area abdominali 

 quoque nigra, lobulo anali puncto rubro, stigmate supra venam subcostalem ad cellule finem introrsum 

 penicillato : subtus fusco-brunneis, linea communi discali fusco, extrorsum albo, in posticis fracta, altera 

 indistincta submarginali albida ; anticis plaga infra cellulam argenteo micante ; posticis angulo anali rufo, 

 lobulo suo nigro, macula juxta earn nigro atomata, tertia inter ramos medianos quoque nigra introrsum late 

 rufo limbata, margine externo nigro introrsum albo anguste marginato. 



Hal. Mexico, Cordova (Rumeli). 



We have four male specimens of this species, all from the same locality— the 

 neighbourhood of Cordova in Mexico; but the female yet remains to be discovered. 

 The species is very peculiar, having a brand on the secondaries supplemented with a 

 tuft of hair. 



T. panchcea and its Guatemalan ally T. pion have also each a tuft on the seconda- 

 ries, but this proceeds from the upper instead of the underside of the subcostal nervure ; 

 aud there is no stigma.
