PERIGONIA.—-PACHYGONIA. 3 
PERIGONTA. 
Perigonia, Walker, Cat. Het. viii. p. 100 (1856). 
Mr. Butler enumerates nine species of this genus, of which P. zlus is but a synonym 
of P. lusca; and others he names seem to rest on very doubtful authority. Three closely 
allied species are found within our region, whereof two have an extensive range in 
South America, the third being also found in Cuba. | 
1. Perigonia lusca. 
Sphinx lusca, Fabr. Sp. Ins. ii. p. 1407. 
Perigonia lusca, Butl. Trans. Z. 8. ix. p. 5327. 
Perigonia interrupta, Walk. Cat. xxxi. Suppl. p. 29%. 
Perigonia ilus, Boisd. Lép. Guat. p. 66 *. 
Hab. Muxtco®; Guaremata 3 (Sallé) ; Nicaragua, Chontales (Belt); Panama (Boucard, 
mus. D.).— ANTILLES, San Domingo ?; Cotomsia (mus. D.); Ecuapor (mus. D.). 
According to Mr. Butler? P. interrupta, Walk.®, belongs here. As regards P. ilus, 
Boisd., I have, through Mons. C. Oberthiir’s kindness, had an opportunity of examining 
the type, and have no hesitation in referring it to P. lusca. 
2. Perigonia restituta. 
Panacra restituta, Walk. Cat. xxxi. Suppl. p. 32°. 
Perigonia restituta, Butl. Trans. Z. 8. ix. p. 582°. 
Hab. Muxico (Hartweg1*), Cordova (Riimeli)—VENEZUELA; Ecuapor (mus. D.); 
AMAZONS, Para 2. | 
In this species, of which I have examined the type, the median yellow spot of the 
secondaries, so conspicuous in both P. dusca and P. stulta, ismuch reduced in size, being 
a small round spot instead of a band as in the allied species. No specimen has yet been 
sent from any part of Central America south of Mexico. 
8. Perigonia stulta. | 
Perigonia stulta, Herr.-Sch. Samml. aussereur. Schmett. f. 106°; Schmett. Ins. Cuba, p. 20’. 
Hab. Panama, Chiriqui (Arcé, mus. D.).—CuBa 2. 
A single specimen in my collection agrees with Herrich-Schaffer’s figure of this 
species !, The orange belt of the secondaries extends along the whole costal half from 
the base to the apex, thus differing from P. lusca and P. restituta. 
PACHYGONIA. 
Pachygonia, Felder, Reise d. Nov. Zool. ii. Lep. Th. iv. t. 75 (1868). 
This genus contains about five species, of which three occur in Central America—two
