This insect appears to be not uncommon in Central America; it does not show any 
amount of variation, except that some specimens are slightly darker in colour than 
others. Letis securivitta, Walk., from Bogota, the type of which, a female, is now in 
my own collection, is not separable from L. herilia. An example obtained by Buckley 
in Ecuador differs from all the others before me in having the secondaries of a uniform 
brown colour, the pale yellowish patch at the apex excepted; but on the underside it 
closely resembles the specimens from Guatemala and the State of Panama. 
8. Letis orcynia, sp.n. (Tab. XXXII. figg. 46,72.) 
Male. Primaries pale brown, clouded with darker brown near the apex and at the anal angle, with a wide 
white uneven band crossing the wing beyond the middle from the costal to the inner margin, across which 
is a narrow line of black lunular-shaped marks, and some white markings close to the apex and at the 
anal angle, the submarginal line black; secondaries pale brown, crossed from the costal to the inner 
margin with darker brown lines, between which are several white lines, and with a large white spot at 
the apex, below which are two white streaks, the submarginal and the marginal lines dark brown ; the 
underside pale greyish-brown, banded with white and dark brown; the fringe of both wings greyish- 
brown: head, thorax, and abdomen pale brown, the antenne and palpi dark brown. The female differs 
from the male in being considerably larger, much richer in colour, and with the markings much more 
distinct; on the underside it resembles the male, but is darker in colour. Expanse, ¢3?, 942 
inches. 
Hab. Mrxico, Cuesta de Misantla (12. Trujillo), Cordova (Hége), Jalapa (Schaus) ; 
Panama, Chiriqui (Zrétsch, in mus. Staudinger), Volcan de Chiriqui 4000 feet (Cham- 
pion).—EcuabDor. 
Of this species we have one male and four females before us; the females from 
Chiriqui are paler and slightly redder in colour than those from Mexico, and they 
have the white markings on the primaries narrower. 
A male from Cordova and a female from Cuesta de Misantla are figured.
