436 BHOPALOCERA. 



The male genitalia of all these insects have their peculiarities. 



M. Mabille has referred us to his Hesperia melangon (Bull. Soc. Ent. Belg. xxvii. 

 p. Ixxv) in naming a specimen sent to him ; but the species now described can hardly 

 belong to that insect, which is stated to have the wings greyish at the base, and the 

 secondaries with two greyish bands on the disc. 



The terminal portion of the tegumen of the male genitalia is a single stout spine 

 with a slight hook at the end ; at the base of this portion is a long erect tuft of hairs : 

 the harpes end in a rounded lobe, and on the dorsal edge is a deep fissure with over- 

 lapping sides, two transverse lobes project inwards from the interior surface of the 

 harpes. (See Tab. LXXXIX. fig. 28.) 



12. Staphylus saletas, sp. n. (Tab. LXXXIX. fig. 30 6 .) 



Alis ferrugineo-brunneis, fusco variegatis; anticis maculis indistinctis discalibus nigricantioribus et punctis 

 duobus subapicalibus hyalinis notatis : subtus ut supra, sed paulo pallidioribus, maculis omnibus forsan 

 distinctioribus ; ciliis ad basin squamis albidis intermixtis ; palpis subtus albidis. 

 2 mari similis, anticis plica costali nulla, punctis parvis tribus evanescentibus hyalinis in disco. 



Hab. Guatemala, Dueiias (Champion). 



A single male specimen differs from others of that sex belonging to this genus in 

 having the wings of a rather rusty tinge, and the obscurer dark markings rather more 

 distinct. It has, too, the palpi beneath clothed with white instead of fulvous scales, 

 and the male genitalia are distinct. These have a tegumen nearly straight for the 

 terminal half, and ending in a blunt rounded point: the harpes are short and rounded; 

 they have a blunt erect spine on the dorsal edge, and a curved serrate ridge on the 

 inner surface. (See Tab. LXXXIX. fig. 30.) 



The female described above doubtfully belongs to this species. 



f. S. EVEMERUS group. 



13. Staphylus evemerus, sp. n. (Tab. LXXXIX. figg. 31, 32 <$ .) 



Alis fusco-brunneis, fasciis transversis obscurioribus vix variegatis ; anticis punctis subapicalibus hyalinis — 

 nullis ( c? ), tribus ( 5 ) in linea obliqua ; palpis subtus squamis ochracco-f ulvis et nigris intermixtis 

 vestitis. 



Hab. Costa Rica, Irazu, Rio Sucio, Cache (Rogers). 



Of this species Mr. H. Rogers sent us several specimens. They hardly differ 

 outwardly from several other members of the genus, but the male genitalia, as will 

 be seen on examining the figures, are profoundly modified. These have an elongated 

 slightly depressed tegumen ending in a blunt slightly hooked point : the scaphium is 

 more fully developed than in the other species, and the harpes end in a long slightly 

 upturned rod, having a finely serrate dorsal edge and long external and terminal
