LED#A.—RHESCIPHA. A485 
Lepidoptera, and Orthoptera, that in Coleoptera having the priority. Two new 
species from our region are added to the genus, and a third is included with consi- 
siderable doubt. 
1. Ledea arduine, sp. n. (Tab. XL. figg. 17, 17 a,¢; 18,2.) 
Male. Primaries and secondaries pale brownish-cream-colour ; the primaries crossed beyond the middle from 
the apex to the centre of the inner margin by a dark brown line edged on the outer side with a fine 
somewhat yellowish line, a dark brown streak partly crossing the wing from the inner margin before the 
middle, a small black dot at the base, one in the middle of the cell, and two at the end of it, and between 
the brown line and the outer margin two very faint narrow waved lines which extend from the apex to 
the inner margin; the secondaries crossed by four faint lines, those nearest the base not reaching the 
costal margin, and with a black spot in the cell; the marginal line of both wings with black points, and 
the fringe cream-colour: head, thorax, and abdomen slightly darker in colour than the wings, the palpi, 
antenne, and anal tuft yellowish-brown, the legs pale brown. The female very similar to the male, but 
with all the markings very indistinct. Expanse, ¢ 2, 153; inch. 
Hab. Guatemata, Volcan de Atitlan 2500 to 3500 feet (Champion). 
In the form of the palpi this species closely resembles Legna semilineata, Walk. 
9. Ledea marcella, sp.n. (Tab. XL. fig. 19, 3.) 
Male. Primaries deep yellowish-fawn-colour, a dark brown streak partly crossing the wing towards the outer 
margin from the inner margin close to the base, and a dark brown line extending from the apex to the 
inner margin, the wing beyond this line nearly to the outer margin of a much darker brown ; secondaries 
blackish-brown, excepting at the anal angle and round the outer margin; the underside pale yellowish- 
brown, both wings crossed beyond the middle by a dark brown line and with a brown spot at the end of 
the cell: head, thorax, palpi, and antenne yellowish-fawn-colour ; the abdomen blackish-brown, the anal 
tuft yellowish-brown ; the legs dark brown. Expanse 13 inch. 
Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet (Rogers). 
Allied to ZL. arduine, from which it may be at once distinguished by the different 
colour and by the position of the lines crossing the primaries. One specimen. 
3. Leda (2) arciva, sp.n. (Tab. XL. fig. 20.) 
Primaries dull yellowish-brown, crossed by two or three very indistinct brown lines, a small black dot at the 
end of the cell and the marginal line with black points ; secondaries darker in colour than the primaries ; 
the fringe of both wings yellowish-brown ; the underside dusky brown, without markings: head, thorax, 
and abdomen brown, the palpi, antenne, and legs dark brown. Expanse 14 inch. 
Hab. Panama, Chiriqui (Ribbe, in mus. Staudinger). 
This insect is only provisionally placed in the genus Ledwa. The primaries are 
much more rounded than in the preceding species, and the secondaries are slightly 
angular; the palpi are similarly formed. 
RHESCIPHA. 
Rhescipha, Walker, Cat. xxxiv. p. 1194 (1865). 
This genus was founded by Walker upon a female example of an insect obtained by 
Mr. Wallace in Brazil; we have received two specimens of the same sex of this species 
from Mexico.
