224 Mr. A. G. Butler on Peruvian Lepidoptera. 



anal angle blackish ; second median interspace to marginal 

 border pale ochreous ; anal margin to third median branch 

 yellow irrorated with red-brown, deeply undate internally and 

 edged with silver ; above the third median the margin becomes 

 red-brown, and is partly edged with silver and partly with 

 yellow scales ; eight discal ocelli black, white-pupilled, with 

 squamose yellow irides, excepting on second median interspace ; 

 anal area irrorated with silver scales. 



Expanse of wings 3 inches 5 lines. 



One of the most remarkable butterflies that has come for 

 years. It is utterly unlike any other Pronophila ; and in the 

 shape of the secondaries, which project somewhat at termina- 

 tion of third median branch, it reminds one of the species of 

 Hetasra and Pierella. 



Genus 10. Corades, E. Doubleday. 



19. Corades Iduna, local form marginalis *. B.M. 



Corades Iduna, Hewitson, Ann. & Mag. Nat. Hist. ser. 2, vi. p. 437 

 (1850) ; Hewitson & Westwood, Gen. Diurn. Lep. p. 355. n. 2, pi. 63. 

 fig. 1 (1851). 



The typical form is from Bolivia ; the species has a third 

 form in Eastern Peru (not Nauta on the Amazons), described 

 at p. 185 of my Catalogue of Satyridse, and which may take 

 the name of C. peruviana. 



20. Corades fusciplaga, n. sp. B.M. 



Allied to C. Cybele. Above like C. Sareba ; differs below 

 from C. Cybele in the dusky tint of all the wings,and in the 

 orange patch of primaries being replaced by a somewhat 

 smaller pale brown patch. 



Expanse of wings 3 inches 2 lines. 



C. Cybele is from Bogota, C. Sareba from Bolivia. 



21. Corades Cistene. B.M. 



Corades Cistene, Hewitson, Exot. Butt. iii. p. 72, pi. 36. figs. 4, 5 

 (1863). 



Specimens previously in the Museum from Quito and 

 Bogota differ from the typical form in the smaller size of all 

 the tawny spots above. 



* The orange patch on secondaries carried on to the margin, without 

 marginal ferruginous border.
