196 HETEROCERA. 
7. Dirphia menander, sp. n. (Tab. XX. fig. 9, ¢ .) 
Male. Primaries light pinkish-red, darker at the base, crossed rather beyond the middle from just below the 
costal to the inner margin by a narrow white band shaded on the outer edge with black, the veins 
between the band and the outer margin white ; secondaries brownish-black, with a central white band, 
the veins light up to the central band, the fringe pinkish-white; underside dusky brownish-black, 
shaded with pink scales, the white bands as above: head and thorax chrome-yellow, shaded with pink ; 
abdomen above chrome-yellow, banded with black ; antenne, the underside of the thorax, and the abdomen 
black ; palpi and legs black. The female is similar to the male, but slightly larger and darker in colour. 
Expanse, ¢, 3 inches; 9, 37 inches. 
Hab. Nicaraaua, Chontales (Belé, ¢ ); Panama, Volcan de Chiriqui (Champion, ¢ ; 
Ribbe, in mus. Staudinger, & ). 
Three examples, two males and one female. A very distinct species. 
8. Dirphia triangulum. 
Dirphia triangulum, Walk. Cat. vi. p. 1851". 
Hab. Panama, Volcan de Chiriqui (mus. Staudinger).—S.K. Brazin, Rio Janeiro 1. 
This species is included in our fauna upon the authority of a specimen from the 
Volcan de Chiriqui in Dr. Staudinger’s collection. This example is almost identical 
with Walker’s type in the British Museum, though of a more reddish-brown colour. 
HYLESIA. 
Hylesia, Hiibner, Verz. bek. Schmett. p. 186. 
Four Tropical-American species were placed under this generic name by Hubner ; 
Bombyx falcifera of the same author (cf. Exot. Schmett. ii. t. 192) will, in my opinion, 
also belong to it. The genus was not adopted by Walker. 
In our country Hylesia is represented by five apparently rare species. 
1. Hylesia falcifera. 
Bombyx falcifera, Hiibner, Samml. exot. Schmett. ii. t. 192. 
Hyperchiria myops, Walk. Cat. vi. p. 1812 (¢ )’. 
Hyperchiria falcifera, Walk. loc. cit. p. 1380. 
Hab. Panama, Volcan de Chiriqui (Ride), near the city (J. J. Walker).—Braziu. 
This species varies in colour, some specimens being very much darker than others. 
2. Hylesia continua. 
Hyperchiria continua, Walk. Cat. xxxii. p. 538 (¢@ )’. 
Hab. Mexico (Sallé, in mus. B.; Coffin, in mus. Oxford), Jalapa (Hoge). 
The males before me agree well with the female (the only sex described) in the 
markings, but they are smaller and considerably brighter in colour.
