460 MR. A. G. BUTLER ON THE GENUS EUPTYCHIA. [Nov. 22, 



clined to consider this form a distinct species, the appearance of 

 the underside being so unlike that of ocirrhoe proper that it would 

 be impossible to place the two insects under one name without such 

 proofs of their apparently specific identity. Even now I am not sure 

 that the two insects might not be separated, as this form differs even 

 from those most closely allied to it in having the front wings more 

 produced, and the submarginal line of the front wings entire to near 

 the apex. 



2. Euptychia lydia. (E. ocirrhoe, $ ?) 



Papilio lydia, Cramer, Pap. Exot. ii. pi. 148. f. C, D (17/9) (but 

 not of Fabricius, Ent. Syst. hi. pt. 1. p. 135). 



Euptychia lydia, Westw. & Hewits. Gen. Diurn. Lepid. p. 3/3. 

 n. 2(1851). 



Satyrus lydius, Godart, Enc. M6th. ix. pp. 464 & 489. n. 40 

 (1819). 



Hab. Surinam. 



The representation of this species may be intended for the female 

 of E. ocirrhoe ; but it is impossible to decide whether it is so or not ; 

 and until we know more of the Lepidoptera of Surinam, this and 

 many other Butterflies figured by Cramer must be considered distinct 

 species. 



3. Euptychia ocypete. 



Papilio ocypete, Fabricius, Gen. Ins. Mant. 260(1776); Ent. 

 Syst. iii. pt. 1. p. 96. n. 296 (1793). 



Euptychia ocypete, Hiibner, Verz. bek. Schmett. p. 54. n. 506 

 (1816); Westw. & Hewits. Gen. Diurn. Lepid. p. 373. n. 10 

 (1851). 



Satyrus ocypete, Godart, Enc. Meth. ix. pp. 463 & 488. n. 34 

 (1819). 



Hab. Surinam. 



Var. Ala supra paulo glaucce ; posticce macula anali nigra fusco 

 pallido cincta. 



Hab. Venezuela; Para; Tapajos (Coll. Bates). B.M. 



This species is not perfectly identical with E. helle of Cramer ; 

 although Fabricius refers to Cramer's figure of that insect, his de- 

 scription does not in all points agree with it. 



4. Euptychia helle. 



Papilio helle, Cramer, Pap. Exot. iii. pi. 194. f. F, G (1782). 



Papilio ocypete (synonym), Fabricius, Ent. Syst. iii. pt. 1. p. 96. 

 n. 296 (1793). 



Euptychia ocypete (synonym), Westw. & Hewits. Gen. Diurn. 

 Lepid. p. 373. n. 10 (1851).
