splendens, the contrast of colour between patagia and tegule 
rather sharper. 
Fore wing coloured and marked nearly as in splendens, but 
easily distinguished as follows: subbasal white mark more 
strongly developed, with more couspicuous M-shaped distal 
edge; reniform stigma (on an average more mixed with 
white) more strongly constricted in middle, 8-shaped or 
spectacle-shaped (the deeper indentation being in proximal 
side) ; postmedian line tneurved between KR? and M’. 
Hind wing 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. 
Yahuarmayo, S. Peru, 1200 feet, May-July, 1912 
(Watkins), type; others from the same locality, from La 
Union, Rio Huacamayo, Carabaya, S.H. Peru (Ockenden), 
and from Rio Ampiyacu, Putumayo, 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 
behind 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 9 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 celebs, sp. n. 
9 .—44—46 mm. 
Head and body coloured nearly as in wylinoides, Schaus, 
the dark brown admixture rather stronger, especially on 
vertex, whichin xylinoides generally remains clear ochreous- 
brown; “‘patagia” edged with bluish- or greenish-white 
proximally. 
Fore wing ochreous brown suffused with red-brown, least 
heavily in costal region; a black lonyitudinal line running 
from near base to termen, in cell and between R} and R’; 
markings otherwise nearly as in «ylinoides, but with the 
dark marks in anterior part. quite small and weak and with
