surface ; hut this is probably due to the age of the specimens. Our figures represent 

 a male from the Polochic valley, and a female from San Geronimo, Guatemala. 



49. Thecla fusius, sp. n. (Tab. LII. figg. 6, 7 6 .) 



5 alis brunneis unicoloribus, subtus omnino T. Jierodoti similis fronte quoque viridi. 



Eab. Mexico, Jalapa ( W. Schaus) ; Guatemala, Chisoy and Polochic valleys (F. D. G. 



6 0. S.) ; Panama, Chiriqui and Line of Eailway (Arce). 



Except that the upperside is brown instead of glaucous-blue, this species differs in 

 no way from T. herodotus, of which it possibly may be a chromatic variety^ We have 

 several specimens, all males, the female being unknown to us ; that sex is probably 

 undistinguishable from the female of T. herodotus. The figure represents a male from 

 the Chisoy valley.

6 alis cyaneis, margine externo nigricante, lobulo posticarum anali producto : subtus viridibus : anticis dimidio 

 ad marginem internum fuscis ; posticis lobulo anali et lunulis quinque ferrugineis, albo atomatis, linea 

 discali obsoleta, ferruginea, fracta, extrorsum albo atomata. 



2 alis fuscis, area interna cseruleo lavata, subtus mari similis. 



Eab. Mexico, Ventanas (Forrer), Jalapa (Edge & W. Schaus) ; Guatemala, Polochic 

 valley, Central valleys (F. D. G. & 0. S.), Purula, Duefias (Champion), Coban (Von 

 TurcJcheim) ; Costa Eica ( Van Patten 1 2 ), San Francisco, Rio Sucio, Cache, Irazu (Bogers) ; 

 Panama, Chiriqui (mus. Standing er). 



Messrs. Butler and Druce described this species from specimens in Van Patten's 

 collection from Costa Rica. We have since received other examples, including the males, 

 from that country, and thence northwards to Southern and Western Mexico. The species 

 is clearly allied to T. herodotus, but the male is of a much more brilliant blue on the 

 upper surface of the wings ; the submarginal row of lunules on the under surface of the 

 secondaries is also a distinguishing feature. A male from Jalapa, Mexico, and a 

 female from Purula, Guatemala, are figured.
