splendcns, the contrast of colour between patagia and tegulae 

 rather sharper. 



Fore %cing coloured and marked nearly as in splendens, but 

 easily distinguished as follows : subbasal white mark more 

 strongly developed, with more conspicuous M-shaped distal 

 edge ; reniform stigma (on an average more mixed with 

 white) more strongly constricted in middle, 8-shapcd or 

 spectacle-shaped (the deeper indentation being in proximal 

 side) ; postmedian line incui'ved between R- and M^. 



Hind iviny whiter than in splendens, the dark borders 

 similar, but on an average appreciably narrower, often 

 almost obsolete in posterior part. 



Underside nearly as in splendens, the dark border of the 

 hind wing tending to obsolescence posteriorly. 



Yahnarmayo, S. Peru, 1.'200 feet, May -July, 1912 

 (TVa t kins), type ; others from the same locality, from La 

 Union, Rio Huacamayo, Carabaya, S.E. Peru {Ockenden), 

 and from Rio Ampiyacn, Pntumayo, Peruvian Amazons. 



A ? from Contamana, Rio Ucayali, Peru, Nov.-Dec, 

 1912, which — on account of the curved postmedian line — 

 probably belongs here, has almost the whole fore wings 

 whitened from base to the reniform and the pale patch 

 beliind it, only an irregular costal border of about 2 mm. 

 width (encroached upon at the subbasal white mark) and a 

 spot on hind margin proximal to the antemedian line 

 remaining normally coloured ; hind wing with the dark 

 borders broad, as in splendens, of which the $ is also 

 unknown. As the three white central spots — the reniform 

 and the spots placed proximally and posteriorly thereto 

 (which are all discernible through their purer white outlines 

 on the whitish area) — are all enlarged, this is possibly a 

 species distinct from both those named. 



6. Acanthodica coelebs, sp. n. 



? .—44-46 mm. 



Head and body coloured nearly as in xylinoides, Schaus, 

 the dark brown admixture rather stronger, especially on 

 vertex, which in xylinoides generally remains clear ochreous- 

 brown ; " patagia " edged with bluish- or greenish-white 

 proximally. 



Fore loing ochreous brown suffused with red-brown, least 

 heavily in costal region ; a black lonyitudinal line running 

 from near base to termeu, in cell and between R^ and R* ; 

 markings otherwise nearly as in xylinoides, but with the 

 dark marks in anterior part quite small and weak and with
