PTERONYMIA. 43 
Hab. Guaremata, Polochic valley, Motagua valley, and San Gerénimo (fF. D. G. & 
O. S.), Volcan de Fuego (0. 8.), Zapote (Champion); Costa Rica (Van Patten*), Irazu 
(Rogers). 
This species bears a close outward resemblance to P. artena, but differs from it in 
having the upper radial of the secondaries placed as a branch of the subcostal, instead 
of being entirely absent as in P. artena. 
Like all species of J¢thomia of similar coloration it affects mountainous districts, 
being probably not found at a lower elevation in Guatemala than 2000 feet. In the 
Volcan de Fuego it flies, in company with Episcada salvinia and Leucothyris zea, in 
the densely forested ravines on the north-eastern slope of the mountain, at an elevation 
of 6500 feet. In Costa Rica it is a common insect. Specimens from that country differ 
slightly from Guatemala ones in having the border of the wings rather darker and less 
rufescent. 
Our description is based upon Guatemalan examples. 
2. Pteronymia alemena. (Jthomia alemena, Tab. V. fig. 1.) 
Ithomia alcmena, Godm. & Salv. P. Z.S. 1877, p. 61’. 
P. tigrani similis, sed minor et alarum marginibus latioribus et omnino fuscis, maculis (una nigra, altera alba) 
anticarum ad cellule finem majoribus et magis oblique positis: subrus alarum marginibus paulo obscu- 
rioribus quam in P. tigrane et maculis albis apicalibus fere obsoletis. 
Hab. Guatemaa Choctum (Lague'). 
We possess a single female example of this species, found in a large collection sent 
us from Choctum in Northern Vera Paz. Its right position must remain doubtful 
until male examples have been examined. In the meantime it seems probable that it 
will prove allied to P. tagranes. 
3. Pteronymia alope, n. sp. 
P. alette (vide infra) quoad alarum colores valde similis, sed anticarum margine interno nigro distinguenda, 
ramum posticarum radialem superiorem quoque habet. 
Hab. Panama, Lion Hill (Jf‘Leannan).— VENEZUELA. 
Of this species we have three specimens, one of which was received direct from 
M‘Leannan, one is said to be from Venezuela, and the third from Mexico; but this 
last must at present be considered of very doubtful origin. The species is very like 
P. aletta in general coloration, but may be distinguished by the black inner border to 
the primaries. A more important character is the presence in the male of an upper 
radial in the secondaries, which, just as in P. tigranes, appears as a small branch to the 
subcostal.
