species as enodiflexa, but the 2nd subcostal of the forewing is connate or stalked, showing — as in sticticata, viridi- 
punctata, etc. •—an advance towards the extinction of its base, i. e. in the direction of Scopula. S. E. Brazil 
(loc. typ.), N. Argentina and Bolivia. — mesembrina form. (? sp.) n. presumably represents oenopodiata in Rio mesembri- 
Grande do Sul, but the appreciably more elongate wings, their browner tone, with the minute irroration more 
reddish, and the weakness of the markings combine to give it. a very distinct aspect, more suggestive of an 
undersized perletaria (p. 78). Type in Museum Wien. 
S. fissaria Guen. (= crinita Warr.) (11 e) forms a separate subgenus (Schistocolpia Wan .), very distinct fissaria. 
(but in the only) through the cleft, hindwing, the vicinity of the excision with coarse specialised scaling on 
the upperside and a long fringe of silky hair on the under. The $ might easily be mistaken for a form of vestita (11a) 
but for the purer white vertex, the small 1) 1 a c k cell-dot of the forewing and more bent postmedian line of 
the hindwing. Cayenne (type) and the Amazon. 
7. Genus: M emipterocles Warr. 
A specialised offshoot of Semaeopus, the hindwing —- especially in the $ — with the tornus pointed, 
or even produced, and with the 3rd radial and 1st median stalked. The 9$ °f divaricata, subrotundata and sub- 
nigrata have on the hindtibia terminal spurs only; the few of rotundata, curviplena and malvina which I have 
examined have retained also one short proximal spur; of flavida and brunneosticta I know only. Exclusively 
Neotropical. 
H. camma Druce (11 e), from Guatemala, is only known from the type $, which has lost its hindlegs, camma. 
but. seems evidently to be a diminutive Hemipterodes, according to its shape and markings and most characters, 
though it is |ust possible it may prove an aberrant Tricentra. 
H. divaricata Warr. (11 e) was named from the branching of the median line of the forewing posteriorly, divaricata. 
a character, however, which is shared by nearly all the species of the genus, the enclosed pale triangle being 
generally very noticeable, divaricata is a small species, of a warm brown colour with dense irroration, the hind¬ 
wing characteristically shaped, the very oblicpie outer line well visible on both wings (slight on the hindwing), 
running to the distal margin in cellule 3, behind which it forms a series of crescents. Underside with the median 
line and rather broad but irregular terminal shading. Venezuela (type), Panama and Costa Rica. 
H. subrotundata sp. n. (11 e). Puzzlingly similar to the preceding, scarcely showing any constant dif- subrotun- 
ference except, that both wings are appreciably more rounded (about as in rotundata). Colour slightly less bright, 
with a more fleshy tinge, outer line running to the margin in cellule 4, or making a tiny loop on the 3rd radial. 
Forewing beneath more uniformly suffused, with no definite dark marginal shade; both wings beneath with a 
discernible (often distinct) postmedian line present, nearly parallel with the median. Venezuela to French 
Guiana, the type $ from Aroewarwa Creek, Maroewym Valley, Surinam, in the Tring Museum. Easily distin¬ 
guished from rotundata by the colour and by the $ hindtibia. 
H. rotundata Dogn. (11 f). Distinguished by its violet-grey tone (in part darker and greyer beneath) rotundata. 
and generally by the outer line, which forms much narrower crescents posteriorly. $ hindtibia 3-spurred. 
French Guiana. 
H. flavida P> out (Ilf). Larger and more yellowish than divaricata , the outer line on the hindwing flavida. 
strong anteriorly, suddenly becoming weak or obsolete about the 2nd radial. E. Peru. 
H. curviplena Warr. (11 f). About as large as flavida, in colour intermediate between subrotundata and curviplena. 
rotundata, distinct from all in the sinuate distal margins. S. E. Brazil. — subvinacea subsp. nov. More vinaceous- subvinacea. 
tinged, the concavities of the distal margins reduced but quite appreciable. Dutch and French Guiana, the 
type $ from St. Jean cle Maroni (Tring Museum). — grisescens subsp. nov. Shape as in subvinacea or slightly inter- grisescens. 
mediate; wings proximally pale, distally grey-clouded, copying exactly the coloration of subnigrata (11 g); 
underside with the cloudings indicated, but less blackish than in that species. E. Bolivia (F. Steinbach), type 
cj (Prov. Sara, Santa Cruz de la Sierra), in Tring Museum. 
H. selaostigma sp. n. (11 f). In shape and coloration near grisescens, the hindwing, however, at least selaostigma. 
as broad and convex-margined as in rotundata, subterminal line forming teeth or angles on the veins, as in sub¬ 
nigrata, median line of forewing double throughout, not only on liindmargin; particularly characteristic are 
the enlarged and glittering cell-marks. Forewing beneath with distal part (somewhat over y 2 ) dark grey. 
St. Jean de Maroni, only the type known (Tring Museum). 
H. nubilata Schaus is unkonwn to me, but certainly belongs to this genus. “18 mm. Very close to nubilata. 
divaricata in shape. Light brown, irrorated with some reddish brown scales. Forewing base darker, limited by
