Pericopis marginalis (I. p. 110). 
To the localities given, add :—-GuaATEMALA, in the city (fodriguez). 
The Guatemalan habitat is now confirmed. The locality Irazu, Costa Rica, must be 
erased, the insect from thence, a male, being referable to P. lycaste. 
6 (a). Pericopis cydon. (Tab. LXXVI. figg. 14, ¢; 15, 2.) 
Pericopis cydon, Druce, Ann. & Mag. Nat. Hist. (6) xiii. p. 175 (go 2) (1894) °. 
Male. Primaries black-brown, with paler markings beyond the cell; secondaries hyaline, the inner margin 
clothed with blackish hairs, the apex and outer margin broadly bordered with black, edged on the inner 
side for about halfway from the anal angle by a wide orange-yellow band, and with two blue spots close 
to the anal angle and a marginal row of white dots, the veins black : head, antenne, and thorax black ;

secondaries orange-yellow, with the apex and outer margin black, and a marginal row of white spots 
extending from the apex to the anal angle. Expanse, ¢ 3, 2 3% inches. 
Hab. Muxico, Jalapa (M. Trujillo!); British Honpuras, Rio Sarstoon (Blan- 
caneux); GUATEMALA, in the city (odriguez). 
The specimen from Rio Sarstoon was originally included by me under P. tibesis 
(antea, i. p. 111); at that time it was the only one I had seen from this locality. We 
figure a pair from Jalapa. 
6(). Pericopis pretides. (Tab. LXXVI. fig. 13, ¢.) 
Pericopis pretides, Druce, Ann. & Mag. Nat. Hist. (6) xiii. p. 175 (¢}) (1894) am 
Male. Primaries dark brown, similar to those of P. tibesis, Druce, but with the markings smaller, and with a 
marginal row of white spots extending from the apex to the anal angle; secondaries hyaline white, with 
the apex and the outer and inner margins broadly bordered with dark brown, a marginal row of small 
white spots extending from the apex to the anal angle: head, antenna, and thorax dark brown ; 
abdomen dark brown, the sides bright red, the underside yellowish-white, banded with dark brown. 
Expanse 23 inches. 
Hab. Mexico, Jalapa (MM. Trujillo '). 
One specimen. It is possible that this insect may be an extreme form of P. cydon. 
Pericopis tibesis (I. p. 111). 
To the localities given, add :—Panama, Chiriqui (Trotsch, in mus. Staudinger). 
Dr. Staudinger’s specimen differs from the others in being larger and paler, and in 
having the black band on the secondaries wider. The locality Rio Sarstoon, British 
Honduras, must be erased, the insect belonging to P. cydon. 
8(a). Pericopis gaumeri, (Tab. LXXVI. figg. 10, ¢; HU, 2).
