median, the latter less oblique, less angled at 1th radial; subterminal weak, especially on forewing. Bolivia 
(type) Peru, Lower Amazon and Surinam. 
P. protrusilitiea Prout. Nearest to turpis (1 e), forewing less pointed, lines browner, the postmedian protru- 
more irregular, the forewing with a fovea behind the base of the median vein and its 2nd branch. Chanchamayo 
(type) and S. Peru. — psycteria subsp. nov. (1 e) is rather paler and greyer, almost or altogether without the psycteria. 
brown admixture, rather strongly recalling argyrodines except in shape. French Guiana. 
P. argyrodines sp. n. (1 e). Rather short-winged for a Pycnoneura, further distinguished from psycteria argyrodines, 
by the somewhat different — in the distal area more uniform — distribution of the dark-grey shading and 
the more sharply expressed whitish markings. Forewing with SC 1 connate or only very shortly stalked in the 
A somewhat better stalked in the fovea stronger than in protrusiliuea, with the median vein more curved 
in front of it; hindwing with cell rather less short. French Guiana: St. Jean de Maroni, type in Mus. Tring. 
The Oberthur collection also contains 1 <$ from Tonantins, Amazons (de Math an). 
P. oxygramma sp. n. $ 38—40 mm. In coloration and markings similar to the least dark ex- oxygmmma. 
amples of rectilineata, but with the dark lines not bordered with white, at the hindmargin of the forewing and 
on the hinclwing more approximated, the postmedian of the forewing still more acutely angled, the subterminal 
line less strong. Structurally distinct in having the median vein of the forewing very strongly swollen from the 
base of the cell to the base of M 2 , the area behind this swelling developed into an elongate fovea, nearly as 
in argyrodines. Muzo, Colombia, 400—800 m (A. H. Fassl), type in coll. Joicey, paratype in coll. L. B. Prout. 
9. Genus: Elntogoiiia Wan. 
Distinguished by the extremely glossy scaling and especially by the loss of the base of the 1st sub¬ 
costal of the forewing, which in consequence arises from the costal. On both these characters icaunaria Walk., 
which was formerly placed in Leptoctenopsis, agrees perfectly with the type species schistacea. In the <$ of scliis- 
tacea, the middle of the abdominal margin of the hindwing is expanded into a small lappet, which is fringed 
with long hair. 
E. schistacea Wan. (1 e). Variable in size; in the smallest $ before me the forewing has a length of schistacea. 
only 10 mm, while in the largest $ it reaches 19 mm; otherwise tolerably constant. Bolivia (type), Matto 
Grosso, Santarem district and French Guiana. — spitzi subsp. nov. is much larger (length of $ fore wing 21 spiiz\. 
or 22 mm), forewing with a conspicuous white cell-spot, both wings with a well-developed crenulate white 
subterminal line, underside more sharply marked. Founded on a single S from Alto da Serra, Sao Paulo, 
Brazil, collected by R. Spitz in October 1922 and now in the Tring Museum, but will certainly prove a valid 
race, if not a species. 
E. icaunaria Walk. (1 e) is distinguishable by its small size, darker and more brownish tone, more icaunaria. 
produced apex of forewing, dark postmedian line, more distally placed than that of schistacea. Described from 
the Amazons, known also from Venezuela and French Guiana. 
10. Genus: Ljcptoctcnopsis Wan. 
Differs from Dolichoneura in the less shortened cell of the hindwing, from Achlora in the shorter palpus, 
from both generally in shape and markings. In most of the species there is a conspicuous and highly oblique 
line from near the apex of the forewing to the proximal part of the abdominal margin of the hindwing, but 
markings, shape and structure are all variable and the genus is not an entirely natural one. The $ antenna may 
have pairs of slender pectinations (approaching those of Achlora) or mere ciliations (as in the preceding genera).

L. melusina Prout (1 e). Smaller than calexaria and differently shaped, besides differing in the struc- melusina. 
ture of the A antenna. The name-typical race, from Paraguay and S.E. Brazil, is strongly suffused with dark 
grey. —- ab. deceptoria nov. is light ochreous brown, almost as in subpurpurea, only a little paler; otherwise deceptoria.

race from Venezuela, scarcely darker in colour than calexaria. The same form occurs in Colombia and French 
Guiana and Tring Museum has one labelled “Amazon”. 
L. tatochorda Prout (1 e). A unknown, but probably with the structure of melusina. Palpus longer, tatochorda. 
distal margins more convex, postmedian line straight, coloration different. Dominica. 
L. subpurpurea Wan. (If). Brighter and less sprinkled with black than tatochorda, the postmedian sub- 
generally very fine and faint, in shape intermediate between those of melusina and tatochorda. Very cliarac- purpurea.
