Alis nigro-fuscis, lituris, inter cellulam et venas, extrorsum radiantibus olivaceis, anticis serie punctorum 

 coloris ejusdem marginem externum subparalleli : subtus anticis fere ut supra, sed apicem versus maculis 

 quibusdam purpureo-albidis et margine ipso maculis septem flavis notatis ; posticis maculis griseis venis 

 divisis margini externo subparallelibus, altera fere obsoleta per cellulse finem, macula elongata flava ad 

 cellulse finem in costam, altera infra earn, sex aut septem minoribus in margine ipso, aliisque per aream 

 internam coloris ejusdem, maculis duabus ad basin coccineis. 



5 alis fuscis, anticis plaga magna venis nigris divisa per cellulse finem et infra earn, angulum analem versus 

 extendente, flava : subtus plaga ut supra, punctis septem exterioribus totidemque in margine ipso flavis ; 

 posticis macula in custa aliisque minoribus per totam aream dift'usis flavis, posticis maculis coccineis ad 

 basin sicut in mari.

This species is allied to E. potamea of Felder, under which name the male appeared 

 in Butler and Druce's list of Costa-Rican butterflies ; but we have no doubt that it is 

 the male of the remarkable insect described and figured by the same authors as 

 Catasticta actinotis. We have now a good series of males and three females from the 

 above localities. 



ARCHONIAS. 



Archonias, Hiibner, Zutr. iii. p. 19, ff. 46 L, 462; Kirby, Cat. Diurn. Lep. p. 429 (partim). 

 Euterpe, Swainson, Zool. 111. ser. 2, ii. pi. 74 ; Doubl. Gen. Diurn. Lep. p. 33 (partim) ; Butl. Cist. 

 Ent. i. pp. 34, 55. 



Structurally this genus differs very little from Catasticta, but the wings are more 

 rounded at the apex, and the second subcostal branch of the primaries is emitted a little 

 beyond the end of the cell. In their coloration, however, its members have a very 

 different pattern, some resembling Papilionidse, such as Papilio mylotes, others 

 certain forms of Heliconinge, Ithomiinse, &c. These latter, of which A. eurytele is a 

 characteristic species, differ from the former in having the middle discocellular of 

 the primaries much shorter than the lower, the latter meeting the median much nearer 

 the origin of the second branch. 



Altogether the genus itself is strictly a neotropical one, extending from the province 

 of Tabasco southward over the whole of Tropical America. 



It contains about thirteen or fourteen species, of which four are found within our region. 



l. Archonias approximata.

Alis fuliginosis, anticis macula ad cellulse finem, altera infra earn, albis ; posticis plaga ultra cellulam venis 

 divisa et marginem internum versus extendente, coccinea : subtus ut supra, sed dilutioribus, anticis macula 

 ad cellulse finem flavida, posticis plaga paginae superioris rosea, puncto interiore ad marginem internum,
