EUPTYCHIA. 85 
This species was originally described by Mr. Bates from a specimen obtained by us 
in the Polochic valley, Guatemala’. It is a common insect in the shady forests, and 
exhibits a considerable amount of variation, which has led to its having been redescribed 
by Mr. Butler. We have a good series of specimens picked from a large number 
of individuals. These show a gradual variation from the type specimen, which is 
dark brown on the upper side, faintly ocellated between the first and second median 
branches of secondaries, beneath rusty brown, both wings crossed near the middle 
by parallel ferruginous lines edged with ochreous, the outer line on the inner side, 
the inner line on the outer side; both wings are paler towards the outer margin. 
Some of our specimens from Costa Rica have the whole of the interior area of the 
primaries and a portion of the secondaries on the upper side ferruginous; these are 
much paler beneath, being of a rich ochreous brown, especially on the anterior wings ; 
they also have two small white spots near the apical ocellus of the anterior wings, 
the second and third ocelli of the secondaries being also white. Between these 
two extremes there is every grade of variety, rendering it quite impossible to recog- 
nize more than one species. Taygetis incerta’, of which we have the type, we consider 
nothing more than a pale variety of the present species. The markings are precisely 
in the same places in each; and we have likewise intermediate examples leading up to 
this form.

After a close examination we are unable to discover any differences by which to 
recognize Mr. Butler’s three species as distinct from each other. We possess the types 
of E. umbracea and of £. cyclops, and have compared these with that of £. poly- 
phemus in the British Museum, and are satisfied as to their all belonging to the same 
species. The South-American race appears to be a trifle smaller; and the ocellus 
beneath at the apical angle of the secondaries is perhaps also smaller in an average 
number of specimens; the transverse lines, too, on the secondaries are usually closer 
together. But these points of difference break down when a series of specimens is 
examined. 
The species is not unlike £. satyrina, differing in the shape of the wings, the more 
even edge of the secondaries, and in the generally darker tint of the wings beneath.
