369 Dr. A. G. Butler on new Pierine Butterflies. 



slightly more yellow ; the spot in the cell and those of the 

 discal series of the primaries nearest to the costa decidedly 

 smaller : secondaries with the external blackish border occu- 

 pying nearly half the wing and crossed by large well-defined 

 spots of the ground-colour ; a marginal series of small white 

 spots. Below, all the pale markings are reduced and the 

 brown areas consequently much broader ; the pale bands also 

 are cream-coloured, not pure white, and the yellow streaks 

 and spots deeper in tint. 



Expanse of wings 62-68 millim. 



Bolivia. Three males. 



6. Catasticta Staudingeri, sp. n. 



Allied to C. corcyra, with which it has been confounded ; 

 it differs above in the restriction of the black apical patch of 

 the primaries, which becomes linear from the second median 

 nervule ; on the under surface the apical border is broadly 

 bright yellow and traversed by two grey lunular markings ; 

 the secondaries are bright yellow, the veins black, with white 

 borders; in the markings of these wings it differs from 

 C. corcyra in having the irregular postmedian stripe placed a 

 little nearer the outer margin and in having a well-defined 

 boldly zigzagged submarginal brown line, the outer angles 

 of which terminate on the margin at the extremities of the 

 nervures. 



Expanse of wings 54 millim. 



E. Peru. One male (type), B. M. 



Also five examples from Ecuador in the Hewitson collec- 

 tion labelled as G. corcyra. Of the latter we have three 

 examples from the Ucayali River, Peru, which correspond 

 exactly with Felder's figure. 



As I have just heard that Dr. Staudinger, of Dresden, is 

 interesting himself in the study of this genus, I have named 

 the preceding very distinct species in honour of him.
