D. Antenna not pectinate, hindtibia of $ (unless in illineata or leopoldina ) with 1 spur. 
E. illineata Wan. founded on a $ from Maroni River measuring 52 mm, is compared with rosei- 
vena (2 a), but is lighter, the veins pale ochreous, not pink, the lines greyer and more indistinct, without 
pale edging, all arising from costal spots, the first more distally placed than in roseivena, the subterminal line 
bluish white; tufts of raised scales red-brown. Hindtibia of $ with 3 spurs. 
E. leopoldina sp. n. (2 a) almost certainly belongs here, but the $ is unknown (unless endoeasta be a 
d'-form to it) and the type has lost its hindlegs. Superficially very like weakly marked liraria, the postmedian 
more proximal and less black; areole wanting. Short and rather weak terminal lunules. Underside weakly 
marked, but with an interrupted dark subterminal shade relatively w'ell developed. Leopoldina, 1900, 1 2 
(coll. Seitz). 
E. endoeasta Prout. Close to piercei (2 a), of which I should have supposed it a race but that the 
antennal teeth of the <$ are longer, nearly as long as the diameter of the shaft. Rather duller, more confusedly 
marked, the double postmedian indicated by ill-defined spots; cell-mark thin: distal margin with short black 
lunules instead of dots. $ unknown. San Esteban, N. Venezuela. 
E. piercei Prout (2 a). This species and the preceding must be very near to illineata Warr., and it is 
possible that one or other may have to sink, piercei has the antennal teeth of the quite short. The coloration 
is scarcely brighter than in divecta, from which it differs in the postmedian line of the hindwing, in its larger 
size, etc. $ unknown. Rio Madeira. Races perhaps occur in French Guiana and Peru. 
E. burrowsi Prout. (2 b) was discovered together with piercei on the Rio Madeira, hut differs greatly 
in the genitalia, which have a different gnathos, a shorter, hairy uncus and quite dissimilar penis, the 
manica strongly spined, the vesica without the 7 strong broad cornuti which characterize that of piercei. A 
lighter and more sharply marked insect, the forewing recalling that of drucei (1 i); the sharply black marks 
on the postmedian of the hindwing are characteristic. $ unknown. 
E. brunnea Schaus is a smaller, more uniformly brown species, intermediate in shape between rosei¬ 
vena (2 a) and an Almodes, distal margin of hindwing deeply dentate, its cell-mark white, scarcely raised. Hind¬ 
tibia of ^ with 3 spurs. Peru. 
E. venturii Prout resembles a small brunnea and may possibly prove a subspecies. Rather darker and 
duller; forewing rather narrower, a small areole present (wanting in brunnea), the basal streak and cell-tuft 
reduced, median area more heavily irrorated, postmedian line less acutely angled. Argentina: El Chaco. 
E. liraria Guen., founded on a $ of unknown “patria”, but perfectly matched by examples from 
Brazil, is closely similar to some rather brown forms of carinenta with the lines, excepting the principal ones, 
not very strong, but differs in having a small areole in the forewing. — athalia subsp. nov. (2 b) is a rather 
narrower-winged, much darker form, on an average rather smaller, which appears to be common at Sapucay, 
Paraguay; subbasal tufts on forewing rather broad. Possibly a distinct species. Type in Mus. Tring. — torva 
subsp. nov. is another form of rather doubtful status. Larger (54—62 nun.), confusingly similar to the brownest, 
most heavily marked forms of carinenta but again with the areole present. Central lines of hindwing much 
less straight and clear than in that species, some heavy black (slightly raised) scaling beyond the discocellulars. 
Carabaya, Chanchamayo, Chachapoyas (Peruvian Amazons) and E. Bolivia, the type from Tinguri, Cara- 
baya, 3400 feet, in Mus. Tring. 
E. carinenta Cram. (= carinata Fb ., carinentaria Hb., bogotaria Walk., repleta Walk.) (2 b) cannot 
be confused with any other species except liraria, on which see above for the differentiation. Forewing without 
areole. Hindtibia of A, as also in liraria, with a single spur. Widely distributed from Central America to the 
Amazon region and Bolivia, first described from Surinam. 
Tribe Hedylicae. 
Remarkably distinct from all other Geometridae, probably a separate subfamily or even a family. 
The slender body in both sexes (with the shape of the abdomen recalling that of some Bhopalocera), short 
antennae, weak and hairy forelegs, short hindlegs, seldom fully spurred, thin scaling and absence of the usual 
Geometrid markings are among the features which give them their individuality. Added to this, their vena¬ 
tion is distinctive: in the forewing the 3rd subcostal arises from near the base of the stalk of the 4th and 5th, 
or even from the cell; in the hindwing the costal (except in Hedyle) is usually remote from the subcostal, 
connected with it by a longish bar. On the very interesting pupae see Macrosoma and Pliellinod.es lucivittata. 
Exclusively Neotropical.
