408 HETEROCERA. 
outer margin of both wings edged with a narrow black line; the underside very much as above, but consi- 
derably paler in colour: head, thorax, abdomen, and legs pale brown, the antenne and palpi brown. 
Expanse 1,1, inch. 
Hab. Mexico, Presidio, near Mazatlan (Forrer); Panama, Chiriqui (idbe, in mus. 
Staudinger). 
Our figure is drawn from the Chiriqui specimen. 
6. Selenis lacia, sp. n. (Tab. XX XIII. fig. 15.) 
Primaries and secondaries pale reddish-fawn-colour, both wings crossed by very fine slightly darker waved 
lines; the primaries at the base and along the costal margin almost to the apex shaded with bluish-white, 
the end of the cell streaked with white ; on the outer margin of both wings about the middle is a large 
bluish-black spot; the underside considerably paler than above, with the lines much more distinct : head, 
thorax, and abdomen reddish-brown, the antenne and legs brown. Expanse 1,4, inch. 
Hab. Panama, Chiriqui (Ribbe, in mus. Staudinger). 
One specimen of this very distinct species has been kindly communicated to us by 
Dr. Staudinger. 
7. Selenis laonome, sp.n. (Tab. XX XIII. fig. 16.) 
Primaries and secondaries fawn-colour; the primaries from the base to the apex broadly bordered with dark 
brown, crossed by paler lines, a brown spot at the end of the cell edged with white, and two dusky brown 
spots on the inner margin close to the anal angle; the secondaries crossed beyond the middle from the 
apex to the inner margin by several dark brown lines; the underside dusky fawn-colour, thickly irrorated 
with black scales, both wings crossed by indistinct brown lines ; the fringe fawn-colour: head and thorax 
dark brown, the abdomen and the four hinder legs fawn-colour, the front legs dark brown, the underside 
of the head and thorax pale fawn-colour, the antenne dark brown. Expanse 1,3, inch. 
Hab. Guatemata, Senahu in Vera Paz 2800 feet (Champion). 
A single example of this distinct species was captured by Mr. Champion ; it is allied 
to S. dentata, but very distinct. 
THYRIODES. 
Thyriodes, Guén. Sp. gén. des Lép. vii. p. 364 (1852) ; Walker, Cat. xv. p. 1586. 
Guénée founded Thyriodes upon an insect received from Mexico ; this is now known 
to extend southwards to the State of Panama, but we have no evidence of its occur- 
rence in the northern part of South America. 
1. Thyriodes flabellum. 
Thyriodes flabellum, Guén. Sp. gén. des Lép. vii. p. 3651; Walk. Cat. xv. p. 1586”. 
Hab. Mexico1?, Teapa in Tabasco (H. H. Smith); Guatemaua, Volcan de Atitlan 
2500 to 3500 feet, San Gerénimo, Senahu (Champion); Costa Rica, Volcan de Irazu 
6000 to 7000 feet (Rogers); Panama, Volcan de Chiriqui 2500 to 3500 feet (Champzon), 
Chiriqui (Ribbe, in mus. Staudinger). 
We are indebted to Mons. C. Oberthiir for kindly sending us Guénée’s types of this 
species, both of which are males. The female varies very considerably. In some 
specimens the pale lines crossing the primaries are almost obsolete ; those from Costa 
Rica are the smallest we have seen.
