Mr. A. G. Butler on a new Genus of Satyridse. 125 



with a terminal fringe (fig. 12). This form is so unlike the last 

 two that I think it impossible for it to be very closely allied to 

 them, 



HiPPARCHioiDEs, gen. nov. PI. III. 



Alse magnae, latae, anticoe maris elongatee, subtrigonatee, angulis 

 rotundatis, costa anticarum miniine undulata ; anticae feminse ma- 

 jores, latiores, margine postico minus obliquo et undulate : posticse 

 magnae, rotuudataB, margine externo undulate : corpus robustum, 

 lanare ; palpis elengatis, articulo apicali prersum porrecte ; oculis 

 exstantibus, minima hirsutis ; antennis clava gradatim formata, vix 

 cestae medium anticarum attingentibus. 



Alae anticae vena costali costae medium attingente, nervulis sub- 

 costalibus regularibus ; vena disce-cellulari prima brevissima, secunda 

 subobliqua et minime undata, tertia directa, longitudine secundae ; 

 nervulis medianis subparallelis, directis ; vena submediana paulum 

 undata ; venis ad basin tumidis. 



Alas posticse vena costali subangulata, cella simplici ; venis regu- 

 laribus, pene aequidistantibus. 



Wings large, expanded ; front wings of male more elongated, 

 subtriangular, the angles rounded off; anterior margin of front 

 wings somewhat waved ; front wings of female larger and wider, 

 the outer margin straighter and waved ; the hind wings alike in 

 both sexes, rounded and large, the outer margin waved : body 

 large, hairy, with elongate palpi (fig. 6), the apical joint extended 

 forwards ; eyes slightly hairy ; the antennae with gradually 

 formed club (fig. 9), and nearly half the length of the front 

 wings ; prolegs of male (fig. 7) more hairy and smaller than 

 those of female (fig. 8). 



Front wings (fig. 3) with the costal nervure extending to the 

 middle of the anterior margin ; the subcostals regular, as in La- 

 siommata ; the first disco-cellular very short, the second much 

 longer, nearly oblique and slightly waved, the third equal to the 

 second in length, but transverse; the median nervules nearly 

 parallel, straight ; the submedian vein slightly waved ; the cos- 

 tal, median, and submedian veins much swollen at the base : 

 hind wings with the costal nervure somewhat angular ; the cell 

 simple; the nervules regular and placed at almost equal dis- 

 tances from each other. 



This genus should be placed near Epinephehy which it some- 

 what resembles in the colouring of the underside of the wings*. 

 The four species contained in it are nearly allied ; they stand as 

 follows : — 



* I have examined the plumules on several genera of Satyridee (see 

 fig. 16), but can find none at all like those on Hipparchioides.
