152 KOVITATES ZOOLOGICAE XXIII. 1916. 



decidedly brown, the latter with a fine pale line at base. Hindwing with the 



dark lines reproduced, much nearer base (at about one-fourth and one-half), sub- 

 terminal slightly better discernible than on forewing ; termen and fringe somewhat 

 brown. 



Both wings beneath without the lines ; forewing with discal dot weaker than 

 above, terminal dots wanting. 



Chanchamayo, Peru, December 1901 (Garlepp). Type in coll. Tring Mus. 



Probably near cinerea Butl., but the straight termen and large cell-dot make 

 it recall Dolichoneura nigrinotata Warr. more than any Pycnoneufa. 



3. Pycnoneura protrusilinea sp. nov. 



(3, 43 mm. Head with palpus deep brown, almost black. Thorax and 

 abdomen concolorous with wings. 



Forewing with termen slightly more convex from apex to R 3 than in the other 

 species, the posterior concavity slight; SC 1 longer stalked (2 to 2*5 mm.) than 

 in the other species; pale drab, densely irrorated almost throughout with deep 

 purple-brown (nearly seal-brown), so as to leave free only a subcostal streak, two 

 bands on which stand the lines, and some ill-defined subterminal cloudings ; 

 costal edge narrowly blackish ; lines bistre ; antemedian at one-third, with a deep, 

 almost V-shaped projection proximad in the middle (its apex between M and M 2 ), 

 otherwise nearly straight ; postmedian at two-thirds, luuulate-dentate, the tooth 

 outward on R 1 long, the lunules inward between the radials and between M 2 and 

 and SM 2 deep; terminal line black, with two or three small triangular swellings 

 in anterior part, otherwise very slightly swollen between the veins ; fringe rather 



bright brown, with a very slender and inconspicuous pale line at base. Hindwing 



similar, with an apical cloud of the pale gronnd-colonr (weakly dark-irrorated) ; 

 first line ill defined ; second arising little beyond the first of forewing, lanulate- 

 dentate, very strongly bent outward between R 3 and M 2 . 



Underside uniform drab. 



Chanchamayo, Peru, November 1901 (Garlepp), type in coll. Tring Mus. ; 

 Potaro River, British Guiana, April 1908, 1 <$ ; Aroewarwa (Jreek, Maroewym 

 Valley, Surinam, April, May and September 1905, 2 c?c?, 1 ?. All the specimens 

 from the Guianas (in coll. Tring Mus., collected by S. M. Klages) are slightly 

 smaller than the type and look a little paler, but are in poor condition. 



Nearest turpis Warr., but with less pointed forewing, browner lines (in turpis 

 tawny olive), much more irregular postmedian and slightly different venation. 



4. Leptoctenopsis tatochorda sp. nov. 



?, 33-36 mm. Head and palpus blackish, mixed with red; palpus fully 

 twice as long as diameter of eye. Body and legs concolorous with wings, foretibia 

 and foretarsus darkened on inner side. 



Forewing with apex minutely produced, termen minutely sinuate behind apex, 

 then somewhat bowed, oblique ; vandyke brown, finely irrorated with black scales ; 

 lines rust-reddish, the postmedian mixed with blackish and slightly ochreous- 

 shaded proximally ; antemedian fine and not strong, from scarcely one-fifth costa, 

 excurved, but with an inward bend between fold and SM 2 ; discal dot black ; 

 postmedian line from costa 2 mm. before apex, almost straight to hindmargin, 

 little beyond middle, only with inappreciable sinuosities in anterior part ; an
