898 HETEROCERA. 
have only received one specimen, captured by Mr. Smith in February 1888. This species 
varies very much in colour and in the distinctness of the lines on the wings. Examples 
from Cuba in my own collection are darker, and others from Rio Janeiro are paler 
in colour; but I have not the least doubt that they all belong to one and the same 
species, 
Fam. THERMESIIDZ. 
SYMPIS. 
Sympis, Guénée, Sp. gén. des Lép. vii. p. 343 (1852) ; Walker, Cat. xv. p. 1548. 
The species placed in this genus by Guénée and Walker are all from the tropical 
regions of the Old World; we have now to record one from Central America. 
1. Sympis agnita, sp.n. (Tab. XXXIII. fig. 9.) 
Primaries and secondaries bright orange-red, thickly irrorated with pale yellow and brown scales, the primaries 
crossed from the costal to the inner margin by three brownish lines, and also with a submarginal waved 
line, the secondaries crossed by two narrow brown lines, the fringe of both wings reddish-brown ; the 
underside pale reddish-yellow, thickly irrorated with brown scales: head, thorax, and the base of the 
abdomen bright orange-red, the rest of the abdomen pale brown ; the antenna, palpi, and legs pale brown. 
Expanse 12 inch. 
Hab, Panama, Chiriqui (Arcé, in mus. D.), Bugaba 800 to 1000 feet, Volcan de 
Chiriqui 2000 to 3000 feet (Champion). 
A common species in Chiriqui. 
ARGIDIA. | 
Argidia, Guénée, Sp. gén. des Lép. vii. p. 845 (1852); Walker, Cat. xv. p. 1549. 
Four species are included in this genus by Walker, and others have since been 
described by Felder and Rogenhofer, and Butler; all these are from Tropical South 
America. 
Three species are now known to inhabit our region, two of them extending as far 
north as Southern Mexico. 
1. Argidia calus. 
Argidia calus, Guén. Sp. gén. des Lép. vii. p. 346, Noct. t. 23. £.10(9)*; Walk. Cat. xv. p. 15517. 
Argidia subrubra, Feld. & Rogenh. Reise der Nov., Lep. t. 118. f. 28, Erkl. der Taf. 118. no. 28 (3). 
Hab. Mexico, Paso de San Juan (Schaus); Guatemava, Zapote (Champion); Panama, 
Chiriqui (Zrétsch, in mus. Staudinger).—Gutana, Cayenne!2; Amazons?; East Perv. 
We cannot agree with Mr. Butler (Trans. Ent. Soc. Lond. 1879, p. 59) in considering 
A. subrubra, Feld. & Rogenh., as conspecific with A. tarchon (Cram.). A comparison 
of the two figures shows they are not in the least alike; but there can be very little 
doubt that A. subrubra is conspecific with A. calus, the figure of the latter having been 
taken from a very dark example.
