teristic are the elongate-triangular bright-red (sometimes black-mixed) subcostal patch of the forewing above 
and the bright purple-reddish, almost unmarked underside. — ab. bimaculata nov. lias a pair of black spots 
outside the postmedian of the forewing, before and behind M 2 . subpurpurea was described from British Guiana, 
but reaches Gorgona Island, Colombia, Trinidad, Venezuela, French Guiana, Para and even — though rarely — 
S.E. Peru, Bolivia and Matto Grosso. 
L. leucographa Dogn. (1 f). Forewing much more falcate, hindwing shaped nearly as in subrufa; the 
white hindmarginal markings distinctive. Peru and the Amazons. 
B. Section Leptoctenopsis Warr. Hind wing with costal vein normal; antenna of slenderly quadri- 
pectinate. 
L, calexaria Walk. (= retectaria Feld.) (If). In addition to the distinctions from melusina uxorcula 
noted above, this species has the oblique line broader and more closely approaching the apex. Only known 
from the Amazons and the Guianas. 
L. franslativena Prout. (1 f). Hindwing more rounded than in the other species of the section and with 
the 2nd radial, especially in the <$, arising much nearer to the 3rd than to the 1st, a very rare character in 
the Geometridae. Amazons, only one pair known until Dr. Zerny took a at Taperinha, near Santarem, 
21—31 July 1927. 
L. murina Warr., of which the type <$ remains unique, has about the size of calexaria, the antennal 
pectinations slighter, the termen of the hindwing still straighter, the ground-colour darker, the line replaced 
by a diffuse black-grey shade which shows (as in mena) an oblique extension baseward from the 1st radial 
to the costal margin of the forewing, some black, pale-edged vein-dots outside this shade, those of the hind¬ 
wing excurved in the middle; fore wing in addition with a hindmarginal patch recalling that of leucographa 
(1 f), but broader and more yellowish. Suapure, Venezuela. 
L. olivacea Prout is another unicum, founded on a £. Intermediate in size and shape between leuco¬ 
grapha and mena , resembling the former in its colour and gloss, but with an oblique, rather indistinct, oliva¬ 
ceous line from near apex of fore wing to middle of abdominal margin of hindwing, edged proximally and 
distally with whitish, especially on the veins. Possibly a remarkable form of mena, as I have seen a ^-ab. of 
the latter from N. Venezuela which somewhat approaches it. Espiritu Santo. 
L. mena Druce (1 f). A rather large and dark species, especially in the Antennal pectinations of 
the $ well developed. Not likely to be confused with any other hitherto-known species. Panama (loc. typ.) 
Colombia, Venezuela, French Guiana, Peru. 
L. redimita sp. n. (1 f). $ 40—45 mm. Close to mena, but with the upperside more red-brown, approach¬ 
ing the colour of subpurpurea, the oblique line fine, deeper red-brown, not black-mixed, still more oblique, 
reaching the abdominal margin nearer the base: antemedian line of fore wing better developed, marked with 
black dots on median and submedian veins; a zigzag postmedian line developed on both wings. Underside 
unicolorous; scarcely brighter than in mena. “Amazons” (ex. coll. Meyer), 4 d'd' in the Tring Museum. Rather 
variable. Dr. Zerxy has recently shown me a from “French Guiana” which agrees accurately. 
C. Section (? gen. div.). Hindwing with costal vein remote from subcostal, $ with hair-tuft at middle 
of abdominal margin; antenna of $ strongly dentate with fascicles of cilia. 
L. subrufa Warr. (1 g). Apart from the structure, this species differs from redimita in having the apical 
projection of the forewing less acute, the ground-colour brighter, especially beneath, where it is as red as in 
subpurpurea and bears on each wing a black cell-dot. The name-typical race is blurred, without definite mark¬ 
ings. Ecuador. — plagiogramma Prout , from French Guiana and the Lower Amazon has a deep red line nearly 
as in redimita, but broader and black-mixed, with some blackish vein-dots outside it, on the fore wing parallel, 
on the hindwing diverging as in redimita; underside also with a thick dark postmedian line. 
11. Genus: Aclilora Guen. 
Antenna of d doubly bipectinate, as in Section B of Leptoctenopsis or more strongly. Wing-shape and 
markings more as in the Indo-Australian genus Noreia; underside more strongly marked than upper. Palpus 
with 2nd joint more heavily scaled than in Section B of Leptoctenopsis, less noticeably curved; 3rd joint in 
$ distinct, sometimes enormously elongate. 
A. Section Euctenachlora Warr. $ without tufts on hindwing beneath, the antennal pectinations long; 
1st median of hindwing from cell. 
A. euctenachlora Prout. The largest species excepting coenobiata. Antennal pectinations exceptionally 
long, about 10 times diameter of shaft and continued nearly to apex. Reddish brown, nearly as in coenobiata,
