MEGISTIAS. 573 



Rab. Mexico, Venta de Zopilote, Tierra Colorada, Chilpancingo, Dos Arroyos, 

 Rincon, Rio Papagaio, all in Guerrero (R. II. Smith). 



This species is confined, so far as we know, to Western Mexico, whence Mr. Smith 

 has sent us fourteen specimens. M. jera closely resembles M. isus, but has the 

 primaries less pointed at the apex, the spots are less distinct, and the male genitalia 

 are differently formed: see Tab. CI. fig. 5. 



3. Megistias labdacus, sp. n. (Tab. CI. figg. 6, 7, s .) 



Alis nitente fuscis, punctis duobus indistinctis inter ramos medianos ad cellulse iinem, tribus in linea 

 transversa subapicalibus (interdum obsolebis), albidis : subtus pallidioribus, anticis maculis ut supra, 

 ad basin et in area mediana paulo obscurioribus ; posticis squamis griseis sparsim tectis, maculis 

 indistinctis serie curvata apicem versus coloris ejusdem ; palpis et corpore subtus albidis. 

 $ mari similis, sed punctis forsan magis obviis. 



Rab. Mexico, Dos Arroyos, Chilpancingo, Tierra Colorada, Rincon, Tepetlapa, and 

 Acaguizotla, all in Guerrero, Cuernavaca, Atoyac (R. II. Smith), Orizaba (R. J. JElwes), 

 Coatepec (coll. Schaus) ; Guatemala, San Geronimo (F. D. G. & 0. S., Champion), 

 Duefias (Champion); Nicaragua, Chontales (Belt); Costa Rica, San Francisco 

 (Rogers). 



Our collection contains a good series of this insect, chiefly from Western Mexico ; 

 we have also two specimens in bad condition — one from Panama, the other from 

 Chapada, Brazil — which possibly belong here. It is a very close ally of the North- 

 American Resperia fusca, Groteand Robins., a species referred to Lerodea by Scudder, 

 but differs in having the primaries faintly spotted above and beneath ; the genitalia of 

 the males (three of which, from Mexico, Guatemala, and Brazil, have been dissected) 

 are very similarly formed in the two species : for those of M. labdacus, see Tab. CI. 

 fig. 7. 



4. Megistias oebasus, sp. n. (Tab. ci. fig. 8, s .) 



Alia fuscis, unicoloribus : subtus anticis ut supra, sed pallidioribus, costa, apice, posticisque area basali 

 purpureo-griseo marmoratis ; ciliis pallidis, indistincte fusco maculatis ; palpis et corpore subtus pilis 

 griseis vestitis. 



$ ignota. 



Rab. Costa Rica, Cache (Rogers). 



Mr. Rogers procured a single male example of this distinct species in Costa Rica, 

 the only one we have seen. It is very different from anything else known to us, and 

 may readily be recognized by the purple-grey mottling of the costa and apex of the 

 primaries and of the whole area of the secondaries, these latter wings being darker 

 towards their outer margin. As our specimen is unique, we have not ventured to 

 dissect it.
