A. Fore wing without fovea. 
B. nigrinotata Warr. (1 c). Rather variable, but with the black cell-dots always stronger than in the nigrinotaia. 
other species; nearly always also there is a blackish mark at the base of R 3 of the forewing. Antennal ciliation 
of c? long. Apex in $ very acutely produced. French and British Guiana, Lower Amazon, Trinidad and British 
Honduras. 
D. innotata Warr. (1 d). $ rather broader winged than that of nigrinotata , $ with apex rather less innotata. 
produced. Darker, cell-dots much smaller, postmedian line more proximal, shaped more as in an Achlora. No 
dark mark at R 3 . Forewing with 1st subcostal stalked with the others (in nigrinotata from cell). British and 
French Guiana, Ecuador and S.E. Peru, few specimens yet known. 
D. eriphyle Schaus, according to a figure of the type from Costa Rica, is rather larger than oxypteraria, eriphyle. 
hindwing slightly more rounded; no white spots or dots; the bands brown, the proximal one on the hindwing 
not double, the subterminal greyish. A worn, rather broad-winged $ from Muzo, Columbia, seems to agree; 
if so, the structure is as in nigrinotata. 
D. missionis Prout (1 cl) is the smallest Dolichoneura , more weakly marked than eriphyle, but with missionis. 
a distinct blackish cell-dot on forewing. Antennalci liation (as also in the following groups) shorter than in 
nigrinotata and innotata. Fore wing with 1st subcostal arising from cell, hindwing with 2nd radial from before 
middle of discocellulars, especially in the <$. Argentina: Misiones. A pair from Villa Rica, Paraguay (coll. 
Joicey) belong with it. 
D. revisa sp. n. <$, 34 mm. Larger and greyer than missionis (about the colour of oxypteraria), distal revisa. 
margins less rounded; the brown lines thicker, more sharply expressed, those of the fore wing more irregularly 
lunulate, with more conspicuously pale edging; cell-dot brown, less small than in missionis, narrowly surrounded 
with pale scaling; both wings with a whitish subterminal line, accompanied clistally by indistinct dark marks, 
nearly as in oxypteraria. $ darker and more variegated than that of oxypteraria, with more produced apex, 
in general colouring recalling Pycnoneura turpis (1 e). Sao Paulo: Alto da Serra, 800 m, 7 and lOMarch 1913 (E. D. 
Jones), type $ and allotype $ in Mus. Brit., together with a $ from “Santa Rosa” which I formerly referred 
doubtfully to missionis. A $ from Rio Janeiro is in the Joicey collection and one from Santa Catharina, Jara- 
gua (Fr. Hoffmann) in Mus. Wien. 
D. ichnaea sp. n. <$, 41 mm. Markings nearly as in missionis (1 d), colour rather darker, size about ichnaea. 
as in eriphyle, different from both in having irregular white dots on the subterminal of both wings, as in albi- 
clentata, and the central band of the hindwing straight (that of eriphyle being bent as in oxypteraria or in P. 
turpis (1 e); proximal line of hindwing pale-edged on both sides. 1st subcostal of forewing long-stalked with 
2nd—5th. Distal margin of forewing rather more oblique than in the species named, very straight. Peru: La 
Oroya, Rio Inambari, 3100 feet, September 1904 (G. Ockenden), type in Mus. Tring. French Guiana, a pair 
in coll. Oberthur, 9 with apex produced. Taperinha, near Santarem (Dr. Zbrny), a worn $. A very worn $ 
labelled “Brazil”, in Mus. Joicey, is probably conspecific, unless the apex is too produced. 
D. oxypteraria Guen. (1 e). Relatively shorter-winged than the 2 preceding, less brown, with white cell-dots, oxypteraria. 
etc. Apex of fore wing in $ minutely produced. The name-typical form is grey. — ab. albidentata Warr. (Id) albidentata. 
is darker and sometimes more mixed with brown, the white markings more conspicuous. Both forms inhabit 
the Guianas, Amazons and Chanchamayo. — squalida Schaus, from Costa Rica, seems to have the apex ($) squatida. 
slightly more produced and the distal margin of the hindwing perhaps rather straighter. 
D. eutheges sp. n. 37—38 mm. Closely similar to rather dark, weakly-marked oxypteraria, the forewing eutheges. 
with the antemedian almost obsolete, no white cell-spot, the hindwing with the median double line straighter. 
White dorsal dots posteriorly on first 3 abdominal segments well developed. Forewing narrower, with apex 
more acute and termen perfectly straight or with the least possible inclination to concavity, suggesting a 
Pycnoneura. Notwithstanding this difference of shape, I should have regarded it as a race or representative 
species but for important differences of venation: forewing with 1st subcostal arising well down the stalk of 
the others (in oxypteraria from cell); hindwing with cell as short as in some Pycnoneura. Gorgona Island, off 
W. Colombia, at light, 200 feet, 20 February 1924 (C. L. Collenette, St. George Expedition), 2 GS in coll. 
Brit. Mus. With them was taken a poor $ apparently indistinguishable from oxypteraria, and with the venation 
of that species, which I at first assumed to be their 9 ; a possibility not yet absolutely precluded, though the 
sexual divergences would be startling. 
D. convergens Warr. (1 d). Easily known by the white ground-colour and heavy markings. Hindwing convergens. 
with discocellulars oblique, the cell anteriorly nearly as short as in Pycnoneura. Forewing with 1st subcostal 
from cell. The are common in the Carabaya district of Peru and also known from French Guiana. I do not 
know the $.
