with a dark brown band edged with yellowish-brown crossing from the inner margin above the anal angle 
towards the outer margin and then extending upwards to near the costal margin, an elongate metallic 
lead-coloured patch between the band and the outer margin, a small black orange-bordered spot (on the 
inner side of which is a small white streak) about the middle of the outer margin, and a narrow yellowish- 
brown submarginal line; the underside of both wings uniformly pale brown, crossed beyond the middle 
by a waved darker brown line, the fringe pale brown: head, thorax, and abdomen dark brown; the collar 
and tegule yellowish-brown ; antenne, palpi, and legs pale brown. The female differs from the male in 
the following particulars:—The primaries are paler and of a more yellowish colour, with the bands 
broader and darker, the second and third reaching the inner margin, and the ocellus entirely wanting ; 
the secondaries have the metallic lead-coloured patch considerably smaller, and also a faint indication of 
a second brown band; and the fringe of both wings is pale yellowish-brown. Expanse, ¢ 9, 
21 inches.

This fine species is allied to D. megalops, Guén., specimens of which are contained 
in the National Collection, but can at once be distinguished from it by the entire 
absence of the purple colour on the primaries. D. lineata is also allied to D. egistoides, 
Bar, from which it differs in having the bands on both wings differently placed, and 
also in its larger size.

This genus contains a few species, all American, the genus ranging from the Amazons 
to California, and also extending to the Antilles.

This species varies considerably in colour, but I have not seen any specimen so green 
as represented by Guénée. The female example before me from the Volcan de 
Chiriqui is almost identical with Felder’s figure.

Primaries dark brown, crossed from the costal to the inner margin by very narrow black lines, which are 
joined together by short transverse lines and form quite a network beyond the middle, and with a bluish- 
grey band nearer the outer margin extending from near the costal to the inner margin, and a large 
yellowish-brown spot marked with minute black and grey dots in the middle at the end of the cell, the
