similar, except that the harpagones are rather more pointed and the dependent lobes 
of the tegumen are serrate at the extremities. 
All the species of this genus have the habit of resting on the under surface of leaves 
within a few feet of the ground.

Mr. Hague obtained us the first specimens of this species at San Gerénimo, where 
Mr. Champion subsequently found it in some numbers, his series including females and 
paired sexes. It was found frequenting a flowering tree on the bank of a small stream 
amongst second-growth woods. . aurantiaca has also been found in Nicaragua, but in 
no intermediate locality. In the State of Panama L. gyda, an allied form, seems to take 
its place.

Hab. Panama, Chiriqui (Arcé), Volcan de Chiriqui (Champion).—Ecvuapor}. 
Of this species we possess a pair from Chiriqui and a single male from Sarayacu in 
Ecuador. It differs in several points from #. aurantiaca, the black margin of the 
primaries being more restricted, there being no black spot at the apex of the secon- 
daries ; the colour of the wings is yellower above and more silvery beneath. The females 
differ still more widely. 
The type of E. gyda, Hew., is said to have come from Brazil; but of the two 
specimens now in the Hewitson collection under this name, one is marked as coming 
from Ecuador and the other from Panama. They agree with our examples, but neither 
of them is the type, which has probably been given away in exchange or destroyed.
