194 HETEROCERA. 
DIRPHIA. 
Dirphia, Hiibner, Verz. bek. Schmett. p. 153; Walker, Cat. vi. p. 1346. 
This Tropical-American genus is closely allied to Ormiscodes and Phricodia; it is 
represented in our country by eight species, all of which are apparently rare. Walker 
included in Dirphia a large number of species, many of which have subsequently been 
placed in other genera. 
1. Dirphia semirosea. 
Dirphia semirosea, Walk. Cat. vi. p. 1859". 
Hab. Muxico! (Hartweq), Jalapa (Hége); Costa Rica (Van Patten), Irazu 6000 to 
7000 feet, Cache, Rio Sucio (Rogers). 
A very variable species. Some specimens are very dark brown, almost black, others 
quite pale brown. 
This is apparently a common insect in Costa Rica; but from Mexico we have only 
received one specimen, a female. 
2. Dirphia citrina, sp. n. (Tab. XX. fig. 6,3.) 
Male. Primaries pale pinkish-brown, shaded with darker brown, and crossed from the costal to the inner 
margin by two narrow yellow lines, upon which are several tufts of white scales; the largest spots are on 
the costal margin ; secondaries uniform pale brownish-yellow, all the veins black, an indistinct line crosses 
the wing below the middle from the costal to the inner margin; underside uniform pale brownish-yellow, 
slightly shaded with pink at the apex of the primaries, a whitish central band crossing about the middle 
of both wings: head, legs, and the underside of the thorax and abdomen pinkish-brown ; upperside of 
the thorax dark brown, with a few long whitish hairs ; abdomen rose-colour, banded with black; antennze 
brownish-black. Expanse 2? inches. 
Hab. GUATEMALA (Boucard, in mus. D.); British Honpuras, R. Sarstoon (Blanca- 
NCAUL). 
Two specimens, one brought home by Boucard some years ago, the other received 
quite lately from Blancaneaux. | 
This pretty little insect is allied to D. semirosea, from which it can be at once distin- 
guished by its smaller size and different colour. The female is unknown. 
3. Dirphia fumosa. 
Ormiscodes fumosa, Feld. Reise d. Nov. Lep. t. 90. f. 3, Erkl. der Taf. 75 bis 107, p. 7 (3)'. 
Hab. Mexico (Bilimek 3). 
This insect is closely allied to D. semirosea, and is doubtfully distinct from that 
species, the only difference being that of colour. 
4, Dirphia hogei, sp.n. (Tab. XX. figg. 10¢, 119.) 
Male. Primaries pale brown, shaded with darker brown, and crossed by two pale whitish bands, the first 
indistinct, the second beyond the cell, extending from the costal to the inner margin, and bordered on the 
outer edge with dark brown, a submarginal whitish waved band from the apex to the anal angle ; secon-
