408 EHOPALOCEEA. 



MASICES, gen. nov. 



In this genus the hind tibiae are like those of Doberes mexicanus, the proximal pair 

 of spurs being absent and the under surface armed with a series of spines ; there is no 

 tibial tuft, and the dorsal edge carries a moderate crest of hairs. The outline of the 

 wings is similar in the two genera, but the apex of the primaries is not quite so acute 

 in Masices. 



The palpi in the latter genus are not nearly so prominently porrect, the terminal 

 joint being small and showing much as in Eantis busirus ; the club of the antennae is 

 more elongated. The neuration is practically the same as in Doberes mexicanus, but 

 the radial of the secondaries is hardly visible, and the lower discocellular is straighter.

Alis brunueis ; anticis linea ab apice ad marginem internum bisectis, macula ad apicem in costa alteraque 

 duplici in cellula nigricanti-brunneis, linea submarginali maculosa pallide brunnea ; posticis margine 

 externo, basi et lineis duabus transversis nigricanti-brunneis : subtus pallidiore brunneis ; anticis area 

 apicali linea maculosa nigricante ab apice bisecta; posticis saturate brunneo nebulosis ; palpis et corpore 

 toto saturate brunneis immaculatis. 



Hab. Mexico \ Atoyac (H. H. Smith), Coatepec ( W. Schaus). 



A large handsome species, somewhat resembling Eantis busirus in general coloration, 

 but differing materially in the shape of the wings and other structural characters, in 

 which it approaches more closely to Doberes mexicanus. 



The specimen described by Plotz appears to have been one of the forms found in 

 Eastern Vera Cruz, in which the underside of the wings is nearly uniform. In Western 

 Mexico and throughout Central America all the specimens we have examined have 

 the apex of the primaries beneath of a rich tawny yellow, and seem separable from the 

 darker insect. We describe them below as Masices sobrinus. 



The male genitalia of If. anticus have the tegumen ending in a single blunt depressed 

 point, at the base of the terminal piece, on either side, is a small lobe ; the scaphium is 

 well developed and granular along its lower surface : the harpes are divided towards 

 the end — the upper portion carries a large erect lobe, which curves outwards and has a 

 strongly serrate upper edge ; the lower portion ends in a slightly upturned point, also 

 serrate at its extremity. (See Tab. LXXXVII. fig. 14.) 



2. Masices sobrinus, sp. n. 



M. antico similis et affinis, sed anticis subtus ad apicem laete fulvis, linea nigra ab apice bisectis, distinguendus.
