PTERONYMIA. 47 
11. Pteronymia fulvimargo. 
Pteronymia fulvimargo, Butl. & Druce, Cist. Ent. i. p. 97*; Butl. Ex. Lep. p. 140, t. 50. f. 5. 
Alis fusco-flavidis hyalinis, venis divisis et fusco-nigro anguste circumcinctis; macula anticarum ad cellule 
finem eodem colore, area apicali maculis flavis valde indistinctis notata ; venis subcostali et mediano rufis ; 
posticarum margine nigro precipue ad angulum analem fulvis: subtus sicut supra, sed marginibus fulves- 
centioribus et anticarum apicibus, posticarum marginibus externis albo punctulatis; antennis omnino 
nigris. 
@ mari quoad colores fere similis. 
Hab. Costa Rica (Van Patten 1). 
This insect is a close ally of P. fulvescens, having the same wing-structure and a 
general similarity of colour-pattern. It can at once be distinguished by the antenune 
being quite black; whereas in P. fulvescens these organs are yellow for the terminal 
third of their length. Van Patten’s collection contained several examples of this 
species; but we have not met with it elsewhere. 
12. Pteronymia aletta. 
Ithomia aletta, Hew. Ex. Butt., Ith. t. vi. f. 31}. 
Alis subhyalinis, anticarum dimidio basali (preeter costam ipsam nigram) lete rufescente, dimidio apicali famoso- 
fusco venis nigris diviso, margine externo et interno ad angulum analem et macula subquadrata apud cellule 
finem nigris, parte apicali maculis serie duplici pallidissime flavis ornata—una extra cellulam (macula 
costam proxime albicante), altera submarginali ; posticis rufescentibus apicem versus hyalinis et venis nigris 
divisis, margine quoque nigro ornatis: subtus sicut supra, sed anticarum apice et posticarum margine 
externo punctulis albis notatis, linea posticarum subcostali nigra; antennis omnino nigris. 
mari similis, sed coloribus letioribus. 
Hab. Panama, Veraguas (Arcé).—CoLoMBIA ; VENEZUELA! 
We have a single male Veraguan example of this species agreeing accurately with 
Colombian and Venezuelan specimens. The species was described from Venezuelan 
insects!. 
Our description of the male is taken from the Panama specimen, that of the female 
from a Colombian one. 
13. Pteronymia agalla, sp.n. (Tab. IV. figg. 6, 7.) 
P. alette similis, sed macula magna extra cellulam flava ornata et area posticarum interna venis inclusis fere 
unicolori rufescente ; antennis omnino nigris. 
Hab. Costa Rica (Van Patten) ; Panama, Chiriqui (Arcé), Veraguas (Arcé). 
Though Van Patten’s Costa-Rica collection contained several examples of this 
species, it is not included in Messrs. Butler and Druce’s paper. It is closely allied to 
P. aletta, both in colour and in the structure of its wings; but the differences given 
above are sufficient to distinguish the two. PP. agalla probably takes the place of 
P. aletta in Costa Rica and its vicinity.
