MUCIA.— MOEYS. 541 



three pieces, the middle piece placed at a different angle to the others : (1) a short 

 streak extending from the base of the second median branch to the first at some 

 distance from its point of origin ; (2) an oblique piece just below this ; (3) a straight 

 streak extending forwards from the middle of the submedian nervure. 



As we possess but two males of M. thyia, each from a different locality, we have not 

 ventured to remove the scales from the wings ; we have, however, dissected the genitalia 

 of one of them. It may be noted that the proximal end of the central piece of the 

 brand slopes downward, instead of upward as in the genus (Bonus.

Hah. Mexico, Rincon in Guerrero, Atoyac (H. H. Smith)— Bkazil, Matto Grosso. 



Of this species we have a pair from Mexico and a male from Chapada, in Matto 

 Grosso. It may readily be separated from most of the allied forms by the black 

 dots on the underside of both wings towards the apex. We have in our collection two 

 females of an unnamed and allied species from Brazil, but in these the black spots are 

 in a different position. M. thyia is very like Euty chide asema (Mab.), but may at once 

 be distinguished by the form of the brand and by the presence of some small black 

 spots near the apex of the primaries beneath. Both species have a curved line of 

 black spots on the underside of the secondaries, though these are rather differently 

 placed in the two insects. For the genitalia of the male, see Tab. XCVI1I. fig. 44. 



MORYS, gen. nov. 



The single species placed here, Apaustus Valerius, Moschl., is one of many very 

 similarly coloured Tropical-American Pamphilinse, each of which exhibits charac- 

 teristics of its own, the present insect having a long, broad, oblique, interrupted 

 brand on the primaries of the male, and the genitalia in this sex very peculiarly 

 formed, the harpes terminating in two widely divergent acuminate points, much as 

 in the species of Mceris. 



The antennae are about half the length of the costa, and have a rather elongate club, 

 terminating in a long crook. The third joint of the palpi is short, stout, and bluntly 

 conical. The primaries are moderately elongate, somewhat pointed at the tip in the 

 male, blunt in the female, the costa arched at the base ; the cell is much less than 

 two-thirds the length of the costa ; the discocellulars are oblique, the upper one twice 

 as long as the lower, the latter being of the same length as the third median segment ; 

 the lower radial is depressed at the base ; the first branch arises slightly before the
