10. Acidalia onca, sp. n. (Tab. LIT. fig. 19.) 
Male. Primaries and secondaries very pale greyish-brown, thickly irrorated with darker scales ; the primaries 
crossed from the costal margin to the anal angle by a rather wide, slightly darker submarginal band, and 
with a small black dot at the end of the cell; the fringe greyish-white ; the underside very much as

35 inch. 
Hab. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (Z. H. Smith). 
A small species allied to A. eupitheciata, Guen., and apparently peculiar to Mexico.

apex with reddish-brown, a very distinct reddish-brown spot on the middle of the inner margin, round which 
the wing is slightly irrorated with reddish-brown scales ; the secondaries crossed by two pairs of indistinct 
brownish spots; both wings with a marginal row of small reddish-brown dots; the fringe long, white ; 
the underside white, entirely without spots, the costal margin of the primaries as above but much paler : 
head, palpi, and antenne brown, the collar, thorax, abdomen, and legs white. Expanse 385 inch. 
Hab. Guatemaa, Cubilguitz in Vera Paz (Champion); Panama, Bugaba 800 to 1500 
feet (Champion). | 
A very distinct species. Our figure is taken from a Bugaba specimen. 
12. Acidalia (?) enona, sp.n. (Tab. LIT. fig. 17.) | 
Primaries and secondaries yellow ; the primaries with the costal margin to the apex broadly banded with 
reddish-brown, the inner portion of the wing slightly irrorated with reddish-brown scales ; the secondaries 
crossed by two broken reddish-brown bands; the fringe very long, yellow: head, thorax, and abdomen 
reddish-brown, the latter yellowish near the anus and on the underside, the legs pale yellowish-white. 
Expanse 8, inch. . 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). | 
One rather worn specimen, captured by Mr. Herbert Smith in March 1888. This 
peculiar species has very narrow wings, but it comes near A. celenna. 
13. Acidalia carna, sp.n. (Tab. LII. fig. 18.) 
Male. Primaries and secondaries pale brownish-grey irrorated with darker scales, each with a very distinct 
small brown dot at the end of cell and a submarginal row of small brown spots, the marginal line brown, 
the fringe grey; the underside very much as above, but with the primaries darker: head, antenne, thorax, 
abdomen, and legs pale greyish-brown. Expanse 4 inch. . 
Hab. Panama, Chiriqui (f7bbe, in mus. Staudinger). 
One specimen. This small species also has very narrow wings.
