fringe dark brown; secondaries uniform dark brown, with an indistinct greyish spot at the anal angle ; 
the underside of both wings dark brown, crossed by a broken band of darker brown markings : head, 
thorax, antenne, and abdomen dark brown. Expanse 1} inch. , 
Hab. Panama, Chiriqui (Arcé, mus. D.), Volcan de Chiriqui 2000 to 3000 feet

A very distinct species. 
3. Dyops phila, sp. n. (Tab. XXIX. fig. 27.) 
Primaries dark brown, shaded with reddish-brown near the base and about the middle, with two white 
waved lines crossing near the base from the costal to the inner margin, a double waved white sub- 
marginal band extending from the costal to the inner margin, and a row of minute white marginal dots 
extending from the apex to the anal angle, most of the veins white, the fringe dark and light brown ; 
secondaries dark brown, palest at the base and along the inner margin, the marginal line black with 
minute white dots, the fringe dark brown: head, thorax, abdomen, and legs dark brown; the underside 
of the head, thorax, and legs yellowish-brown. Expanse 2 inches. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion), Volcan de Chiriqui (Arcé, mus. 
D.; Ribbe, mus. Staudinger). 
4. Dyops minthe, sp.n. (Tab. XXIX. fig. 28.) 
Primaries dark brown, darkest at the base and along the inner margin, with two waved dark brown lines 
crossing from the costal to the inner margin, a wide submarginal waved white band extending from the 
apex to the inner margin close to the anal angle, and about the middle of the band a dark brown spot, 
the outer margin brown; secondaries silky brown, palest at the anal angle and round the outer margin, 
a minute black dot at the anal angle: head, thorax, abdomen, and antenne brown; the legs pale brown. 
Expanse 12 inch. 
Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion; Ribbe, in mus. 
Staudinger).—Brazit, S. Paulo. 
This species is allied to D. phila, from which it chiefly differs in the wide white 
submarginal band of the primaries. In a variety in Dr. Staudinger’s collection the 
white band is almost obsolete. The example from Brazil in my own collection is 
altogether duller in colour than those from Central America. Our figure is taken from 
a typical specimen in Dr. Staudinger’s collection. 
LITOPROSOPUS. 
Dyops Groupe ii., Guénée, Sp. gén. des Lép. vi. p. 284 (1852). 
Litoprosopus, Grote, Trans. Am. Ent. Soc. ii. p. 8309 (1869); List of North-American Moths, 
p- 33 (1882). 
Grote refers three species to this genus: Noctua hatuey, Poey, from Cuba; Dyops 
confligens, Walk., from Honduras and the West coast of America; and Dyups futilis, 
Grote and Robinson, from Florida. The two first named are, I have no doubt, one 
and the same species; and it is extremely doubtful if the third is distinct, as specimens 
of it lately received from Mr. H. Edwards, from Florida, apparently only differ from 
L. hatuey in their rather smaller size.
