XIII. A Monograph of the Genus Yphthima ; with Descrip- 
tions of two new Genera of Diurnal Lepidoptera. By

[Read December 5th, 1864.] 
I wAve myself experienced so much difficulty in determining the 
species of the genus Yphthima, as to believe that if I have success- 
fully worked it out, I shall have been of some use. It is an 
excellent genus; I have neither admitted nor rejected any species 
about which I have the least doubt. Some of the new species 
are from the Collection of Mr. Wallace. 
The genus Cenyra is nearly allied to Yphthima, as well as to 
Cceenonympha; from both it differs in the neuration of the wings, 
from Coenonympha in its very different palpi. 
Genus Canyra, Hewitson. 
Head small; eyes small. Palpi long, straight, much com- 
pressed, thickly clothed with hair; the third joint long and nearly 
naked. Antenne slender, short, slightly and gradually thickened 
to the point. 
Anterior wing rounded; costal margin arched, apex and outer 
margin rounded ; inner margin nearly straight; costal nervure 
much swollen at the base, extending to the middle of the margin ; 
subcostal nervure with four equi-distant branches, two before the 
end of the cell; discoidal cell half the length of the wing, the 
nervures which close it forming a regular curve inwards, the 
first obsolete, the second and third of equal length, joining the 
third branch of the median nervure at a distance from its base. 
Posterior wing very round; the costal nervure reaching a little 
beyond the middle of the margin; the subcostal branched before 
the end of the cell; the disco-cellular nervules, which close the 
cell obliquely, are slightly curved inwards, the first being half as 
long as the second.
