112 HETEROCERA. 
I am indebted to M. C. Oberthiir for sending me Boisduval’s type; it is quite unlike 
any other species with which I am acquainted. 
10. Pericopis thetis. 
Euprepia thetis, Klug, Neve Schmett. p. 5, t. iv. figg. 1, 2°. 
Daritis thetis, Walk. Cat. iii. p. 6187; Butl. Ann. & Mag. Nat. Hist. 4th ser. xvi. p. 170°. 
Pericopis thetis, Butl. Trans. Ent. Soc. 1872, p. 57. 
Eucharia mariamne, Hiibn. Sammi. exot. Schmett. t. 999. figg. 1-4. 
Hab. Mexico? 3 (Deppe)1, Jalapa (Hoge) ; Costa Rica (Van Patten). 
The Costa-Rican example differs slightly from those from Mexico, the semihyaline 
bands on the primaries being considerably wider in the male specimen before me, and 
the red marginal band of the secondaries narrower. ‘This species appears to be very 
rare; I have only received three specimens. 
11. Pericopis fenestrata. 
Pericopis fenestrata, Butl. Trans. Ent. Soc. 1872, p. 50. 
Daritis fenestrata, Butl. Ann. & Mag. Nat. Hist. 4th ser. xvi. p. 170. 
Hab. GuatemMaLa, San Gerénimo (Salvin). 
Mr. Butler states that this is a local form of the Mexican P. thetis. I have not seen 
the type of P. fenestrata. 
12. Pericopis leonina. 
Pericopis leonina, Butl. Cist. Ent. p. 89*; Trans. Ent. Soc. 1872, p. 58; Lep. Exot. t. Ixi. fig. 10; 
Ann. & Mag. Nat. Hist. 4th ser. xvi. p. 167. 
Hab. Costa Rica, Cartago (Van Patten) 1, Irazu 6000 to 7000 feet (Rogers). 
13. Pericopis bivittata. 
Pericopis bivittata, Walk. Cat. ii. p. 848°; Butl. Trans. Ent. Soc. 1872, p. 56; Ann. & Mag. Nat. 
Hist. 4th ser. xvi. p. 167. 
Pericopis disjuncta, Walk. Cat. vii. p. 1655’. 
Chetone aorsa, Boisd. Lép. Guat. p. 90°. 
Pericopis lucretia, Butl. Ann. & Mag. Nat. Hist. 4th ser. xv. p. 340°; ib. xvi. p. 167. 
Hab. GuatemMata?, Purula, Zapote (Champion); Panama (fibbe, mus. Staudinger), 
Volcan de Chiriqui 2000 to 3000 feet (Champion ; and Ribbe, mus. Staudinger), Veraguas 
(Salvin, mus. D.)*.—CotomBiA 2, Manaure (Simons, mus. D.); VENEZUELA 1. 
This is a very variable insect. I have a fair series of specimens before me, but no 
two are quite alike; in some specimens the bands on the primaries are much wider 
and quite pale in colour, in others they are narrower and quite dusky; and the black 
band of the secondaries is (in some specimens) broad and well defined, in others it is 
almost obsolete and thus approaching very closely to P. amphissa from South Brazil.
