326 [April 



The shape of the wings distinguish it from Ingura, and the more 

 sunken head and less elevated thorax from PenciUarla. 



The ornamentation is peculiarly beautiful. Various rich shades of 

 brown are intersected by bluish white narrow lines, a large apical white 

 patch • within, the posterior wings are white, diaphanous, as in the other 

 genera of this group. 



Ripogenus pulcherrimus. nov. sp. 



Anterior wings reddish-brown, the lines narrow, neat, bluish white, 

 median space with a distinct pale bluish patch between the median 

 lines interiorly, a large well-defined whitish apical patch. Basal line 

 indistinct; transverse anterior bluish white, with darker edges, below 

 the s. c. vein forming a single rounded curve, outwardly margining an 

 oblique oblong dark claret-brown spot which is surrounded on the inner 

 side by a similar bluish line. Between this spot and the base, the wing 

 is duller but similarly shaded, becoming more reddish at costa. Median 

 space reddish brown, very large above, narrow below, since the trans- 

 verse posterior line originates very near the apex and below the s. c. 

 nervure runs very obliquely to internal margin. Orbicular spot waut- 

 ing, renifonu bilobed, narrowly elongate, distinct, consisting of a black- 

 ish point above constricted to a pale line at the center, which line sur- 

 rounds a small rounded space, darker than the wing, below. 



Veins marked with whitish below the disk and in terminal space. 

 Immediately on internal margin is a white sub-triangular spot below 

 the bluish space which extends between both m. lines interiorly, and 

 beyond, approximate to the t. p. line, is a round yellowish well-defined 

 smaller spot. Terminal space dark claret brown, subterminal line appa- 

 rent at internal angle, and joining the t. p. line at just below the costa 

 where it forms a broad whitish mark on the line, and encloses a some- 

 what analagous space to that on the basal space margined by the t. a. 

 line ; fringes greyish, interrupted with brownish ; costa marked with 

 whitish. Under surface confusedly marked, t. p. line apparent, brown- 

 ish ; the wing is whitish along internal margin, in terminal space and 

 particularly at the apex, discal spot apparent. 



Posterior wings white at base and along internal margin, a subter- 

 minal broad angulated blackish band bent below costa, external margin 

 brownish, discal spot faint, covered by anterior wings when expanded, 

 owing to the retreating disc. Under surface whitish crossed by narrow 

 faint dark lines, discal spot distinct, brownish. 



Head and palpi rich brown. Tegulae paler, like upper median space 

 in color, with terminal pale lines. Thorax clothed with long rich vinous 

 brown hairs, which color spreads over the basal four segments of the
