Hab. Mxxico, Cordova (Hoge); Guatemaua, Chuacus}, Cerro de Zunil (F. D. G. 
& O.S.). 
Described first by Mr. Bates from specimens found by us at Chuacus, in Guatemala, 
in 1861. Salvin afterwards procured a single specimen at the hacienda of Las Nubes, 
on the slope of the Cerro de Zunil; and we have recently received another example 
taken by Mr. Hége in Mexico. All these are females. It appears to be a rare species, 
as in all the collections we have received no other specimens have occurred. Its nearest 
ally is B. macrosiris of Guiana, of which there is a figure in ‘The Genera of Diurnal 
Lepidoptera ;’ and of this species there is an example in the British Museum which 
strongly resembles D. strix, especially in the marking of the underside. J. strix, 
however, differs from this at first sight in having a conspicuous white band crossing 
the end of the cell of the anterior wings towards the anal angle. 
The gradually clubbed antenne and the rounded wings of this species indicate that 
its position is in this genus rather than in Brassolis, where Mr. Bates originally placed 
it. The markings of the underside, however, are different from those of D. darius, 
being much more strongly shown and in more vivid colours. Indeed, in this last respect 
hardly any butterfly that we know of shows so beautiful and harmonious a combination 
of colours. 
A specimen from Chuacus is figured. 
BRASSOLIS. 
Brassolis, Fabricius, Ill. Mag. vi. p. 282 (1807), partim ; Westwood, Gen. Diurn. Lep. p. 350. 
This genus, as restricted by Prof. Westwood, contains three closely allied species, one 
of which (B. isthmia) is peculiar to Central America, a second (5. sophore) to Guiana 
and the basin of the Amazons, and the third (B. astyra) to Eastern Brazil. A fourth 
species (B. macrosiris) included in the genus by Prof. Westwood, should, in our opinion, 
be removed to Dynastor. 
Like Dynastor the terminal joint of the palpi is very short, and the prediscoidal cell 
of the primaries is moderately large; but the primary wings are much more pointed, 
and the antenne abruptly clubbed. The costal margin, too, near the base is concave, 
especially in the male. The tegumen of the male is a simple hook without lateral lobes 
on the ventral surface. The harpagones are also simple, short, and stout, with a slight 
serration near the tip of the dorsal edge. There are no pencils of hairs on the 
secondaries.
