Bogota 1 . We have specimens of Mr. Simons' s collecting from Northern Colombia, 

 others from Venezuela. Bates found it at Para, and Mr. Herbert Smith at Chapada, 

 in Matto Grosso. 



ZOPYRION, gen. nov. 



This genus, which contains Helias satyrina, Feld., and the two species mentioned 

 below, agrees with Timochreon in the general facies of the species, which are somewhat 

 like SatyrinaB in their colour ; but Zopyrion differs from Timochreon in having a more 

 slender body, more rounded wings, a more abrupt club to the antennas, a longer, more 

 prominent terminal joint to the palpi, and a distinct costal fold to the primaries. 



The species range from South-western Mexico to South Brazil. 



l. Zopyrion sandace, sp. n. (Tab. XC. figg. S, 9, 10 s .) 



Alis fuscis fere unicoloribus,, ciliis sordide albis, venis fuscis interrupts ; auticis punctis indistinctis sex ultra 

 cellulam, aliisque quatuor discalibus, omnibus lineam maculosam sinuosam formantibus, pallide fuscis : 

 subtus griseis, anticis ochraceo lavatis, ad marginem externum fusco irroratis ; posticis lineola irregulari 

 transversa per cellulam alteraque duplici abbreviata discali, punctisque submarginalibus pallide ochraceo- 

 fuscis ; palpis subtus albis, penicilla tibiali nigra. 



2 mari similis, plica costali nulla neque penicilla tibiali ; alis subtus obscurioribus. 



Hab. Mexico, Venta de Zopilote, Acapulco, Dos Arroyos, Rio Papagaio, Tierra 

 Colorada (H. H. Smith) ; Guatemala, Volcan de Santa Maria ( W. B. Richardson). 



Mr. Smith sent us a series of specimens of this species all taken in September and 

 October at various places in the State of Guerrero, and we have one specimen from 

 Mr. Richardson taken on the slope of the Volcan de Santa Maria in Guatemala. 



The species is evidently allied to Z. satyrina (Feld.), but may at once be distinguished 

 by the absence of the dark submarginal spots on the secondaries beneath. 



Besides the two species already mentioned, we have several specimens of a third in 

 South America which we describe below *, as well as indications of others of which 

 our materials are scanty. 



The male genitalia of Z. sandace have a double pointed tegumen, under which is a 

 well-developed scaphium : the harpes are cleft at the end, where there is a deep sinus; 

 the upper portion curves downwards, and the under portion is wider, curves upwards, 

 and both have their ends serrate ; from the base of the inside of the harpe a long lobe 

 proceeds outwards, which is pointed and reaches a little beyond the bottom of the cleft, 

 its upper margin being sinuous and thickly serrate. (See Tab. XC. fig. 10.) 



* Z. sandace affinis, sed alis subtus omnino magis ocbraceis, lineolis posticarum omnino disruptis vix obviis. 

 Hab. Brazil, Corumba in Matto Grosso (H. H. Smith).
