LANGSDORFIA.—HEPIALUS. 231 
1. Langsdorfia francki. 
Langsdorfia franckii, Hiibn. Samml. exot. Schmett. ii. t. 192. ff. 1 and 2; Walk. Cat. vii. p. 15277. 
Hab. Nicaragua, Chontales (Belt); Costa Rica, Irazu 6000 to 7000 feet (Rogers) ; 
Payama, Bugaba 800 to 1000 feet (Champion), Volcan de Chiriqui (Ribbe, in mus. 
Staudinger).—CotomBia; Ecuapor; Braziu}. 
None of the specimens before me are so large as represented in Hiibner’s figure, 
though they agree in all other respects. | 
2. Langsdorfia forreri, sp.n. (Tab. XXIV. fig. 5.) 
Primaries pale brownish-white, thickly irrorated with darker brown streaks, with a crescent-shaped dark 
brown mark edged with pale brownish-white close to the apex, an ill-defined dark brown patch at the 
end of the cell, and a dark reddish-brown rather broad line close to the base crossing from the costal 
margin to the inner margin; secondaries dirty brownish-white, thickly streaked with minute darker 
brown lines ; the underside as above but more lightly marked with brown: head, thorax, and abdomen 
brownish, the tufts of hair on the anus pale brownish-white, a pale line on each side of the abdomen; 
antenne and palpi pale brown ; legs and the underside of the abdomen dirty brownish-white. Expanse 
1} inch. ; 
Hab. Mexico, Tres Marias Islands (Lorrer). 
Two examples. This curious and distinct species closely resembles a Zeuzera, but 
has the neuration and antenne of Langsdorfia. 
ZEUZERA. 
Zeuzera, Latreille, Hist. nat. des Crust. et Ins. xiv. p. 175 (1805) ; Walker, Cat. vii. p. 1528. 
Walker placed twenty-nine species in this genus, and since then various others have 
been described. Zeuzera is very widely distributed in the Old and New Worlds; some 
of the Indian and African species are very beautifully coloured. 
1. Zeuzera cognata, (Tab. XXIV. fig. 6, 2.) 
. Zeuzera cognata, Walk. Cat. vii. p. 15327. 
Hab. Mexico, Presidio (forrer), Jalapa (Hége); Honpuras (Dyson 1, mus. Brit.) 
This species is allied to Z pyracmon and Z. fracta, Walk., the former of which is 
from Surinam and the latter from an unknown locality. The male of this insect is 
considerably smaller than the female; we figure one of the latter sex from Jalapa. 
Fam. HEPIALIDZ. 
HEPIALUS. 
Hepialus, Fabricius, Gen. Ins. p. 162 (1776). 
Hepiolus, Mliger, Mag. i. p. 138 (1801). 
This well-known genus is found all over the world; the tropical species, however, are 
very little known as yet. From our country we have only received a single species.
