Chanchamavo, Peru ; three £ $ . 



Close to A. leprosa, Warr. Nov. Zool. xiv. p. 297, of which 

 it may prove a local form. The three specimens do not vary 

 except in size ; they are much paler and more weakly marked 

 than Warren's species, the outer line of fore wing less 

 " creuulate," &c. Venation as in that species (SC 1 and SC 2 

 of fore wing both free). 



Acrotomodes hemixantha, sp. n. 



2; . 3.2 mm. — Head purplish, basal segment of palpus 

 yellow; thorax and abdomen purplish above, yellow be- 

 neath ; legs in part ochreous, fore and middle tibiae and all 

 tarsi dull purplish. Fore wing deep slaty purple, lines finely 

 grey ; antemedian outcurved from one-fourth of costa to 

 submedian fold, thence approximately vertical, incurved 

 between M and SM ; externally edged with darker; post- 

 median from two-thirds costa shortly oblique outwards, 

 angled on SC, then inwardly oblique to three-fifths inner 

 margin, paler at costa and preceded by a dark line : upper 

 end of cell and space beyond to angle of postmedian line 

 dull olive, showing a blackish vertical linear cell-spot, veins 

 SC and R 1 along it dotted with dark ; subterminal line 

 invisible except at costa, where it is preceded by a dark 

 triangular shade, the extreme apex bluish grey ; fringe dark 

 purplish. Hind wing concolorous, with a median dark, 

 pale-edged line; costal area, especially at base, dull pinkish. 

 Underside dull slaty purple, the base of fore wing, and the 

 hind wing to beyond one-half, dull deep yellow. 



Pozuzo, E. Peru, 800 m., October 1907; one £ . 



Of closely the shape and general aspect of Acrotomodes, 

 and agreeing therewith in many points of structure, but the 

 generic position somewhat uncertain. Apex of fore wing 

 somewhat less acute, termen less oblique posteriorly and not 

 at all giblxms at K 1 ; SC 1 " 2 longish stalked, their stalk con- 

 nected (by a backward-running bar) with 0. In all the 

 other Acrotomodes which 1 have been able to examine SC 1 is 

 unconnected with C, though it varies in being either short- 

 stalked with SC 2 (sporadata) or free (leprosa and custa). 



Gynopteryx (?) punctinotata, sp. n. 



cJ. 38 mm. — Head, thorax, abdomen, and legs all yellow; 

 hind tibia with a pencil of reddish hairs. Fore wing pale 

 lemon-yellow, with a few red speckles; costa streaked and 

 dotted with dull red-brown, especially in basal half ; inner 

 line shown by three red-brown dots in a slight curve, on SC, 

 M, and SM', the first the largest; outer line from costa at
