A common insect in Mexico, whence we possess a long series from both the Eastern 

 and Western States. We have received a Venezuelan specimen from Mr. Semper 

 marked " Cobalus catocala, Herrich-Schaffer," but it does not agree with the brief 

 description of that species. Our figures are taken from Mexican specimens. For the 

 genitalia of the male, see Tab. CI. fig. 11. 



6. Megistias fraus, sp. n. (Tab. CI. fig. 12, <$ .) 



Alis nitide fuseis, anticis punetis tribus subapicalibus in linea transversa albo-hyalinis : subtus pallidioribus 

 anticis obscure fusco marmoratis, plaga subquadrata subapicali fusca ; postieis fasciis tribus, una ad basin 

 secunda mediana, tertia submarginali, obscure fuseis. 



Bab. Mexico, Teapa (H. H. Smith) ; Guatemala, Panima in Vera Paz (Champion) ; 

 Honduras (Mus. Brit.). 



At present we have only seen three examples which certainly belong to M. fraus, 

 a male in irood condition from Teapa, a worn specimen from Panima (now without a 

 body), and another in the British Museum, all of them being from the Atlantic slope. 



Except for the three subapical hyaline spots on the primaries, the upperside is 

 of a uniform fuscous colour; the secondaries beneath are conspicuously marked with 

 alternately light and dark bands.

Alis fuseis, anticis punetis duobus inter ramos medianos ad cellulas finem, duobus aut tribus in linea transversa 

 subapicalibus et duobus minutissimis in costse medio (interdum obsoletis), sordide albis : subtus anticis 

 fuseis, punetis ut supra sed majoribus, costa (apicem versus latiore) ferruginea, ad marginem externum 

 griseo notatis ; postieis ferrugineis, fasciis duabus irregularibus a margine interno, una ad costam altera 

 apicem versus extendentibus, griseis ; ciliis griseis, fusco maculatis : subtus palpis et corpore pilis 'albidis
