basal ray and a large black cell-end spot; a brown submarginal shadow and double vein-dots are before the 
upper half of the margin. Hindwing white with a brown marginal line. French Guiana. Expanse of wings: 
35 mm. 
143. Genus: Bahaia Dyar. 
From this genus to the end the species mostly lack the areole of the forewing and at the same 
time vein 5 of the hindwing. Antennae of S not pectinated to the tips, a hair-tuft is on the vertex; vein 
6 of forewing on a joint stalk with the 4 lower subcostal branches, 5 arises from the centre of the cross-vein. 
The costal vein on the hindwing branches off from the centre of the cell. Only 1 species. 
Type of genus: B. sceletaria Dyar. 
B. sceletaria Dyar (155 c). Forewing light grey, strewn with violettish-brown scales, and with a red- sceletaria. 
brown longitudinal patch through the cell, then darkened by brown shading obliquely as far as below the 
apex, bordered below by an undulate brown line, forming an angular spot below vein 2; traces of inter¬ 
rupted lines are visible. Hindwing whitish. The $ is more monotonous and less marked, with darker hind- 
wings. Mexico (Colima). 
144. Genus: Procolax Schs. 
The exterior is exactly like that of the following genus Colax from which it differs in the subcostal 
branches being differently stalked, vein 10 proceeding from the joint stalk farther towards the apex than vein 
7; besides the $ has tuftedly ciliated antennae. 
Type of genus: P. apulana Schs. 
P. apulana Schs. (155 cl). Shaped and marked exactly like the following species, but the forewing is apulana 
of a lighter red-brown colour, the inner margin and distal area lighter brownish-grey, the costal margin 
strewn with iron-grey; the black transverse lines are more distinctly prominent on the light ground-colour. 
Costa Rica to Brazil. 
145. Genus: Colax Him. 
Antennae of both sexes pectinated in the basal two thirds, the short palpi hairy, hair-tufts at the 
bases of the antennae. Distal margin of the narrow forewing angular on vein 5, concave below it; vein 6 of 
forewing stalked with the 4 lower subcostal branches, the second subcostal branch from above arises pro- 
ximally from the lowest. Veins 3 and 4 of hindwing arise separately, the costal-marginal vein branches off 
from the centre of the cell. 
Type of genus: C. apulus Cr. 
C. apulus Cr. (155 d). Forewing purple blackish mixed with chestnut-red, especially basally and in apulus. 
the cell, lighter greyish-brown at the inner margin and distal margin behind the whitish, notchless subter¬ 
minal line, with black angular transverse lines, and 2 small silvery white spots oblicpiely above each other 
at the cell-end. Hindwing diaphanous light grey, darkened at the apex. Guiana to Colombia. 
C. phocus Schs. (155 cl) is extremely similar to apulus, but the forewing is much darker velvety browm, phocus. 
the inner margin and distal margin are somewhat lighter, the postmedian line is not so very undulate and 
the two silvery spots in the cell are near together. Hindwing white, brownish-grey only at the inner margin 
and the fringe. Brazil (Rio cle Janeiro). 
146. Genus: Schausiacles Dogn. 
Exterior exactly like that of a Hemiceras lepida from which genus, however, it differs in the second 
subcostal branch from above arising separately from the cell, vein 5 arises from the upper cell-angle. Neu- 
ration of hindwing not essentially different, the exhibits a triangular stigma at the anal angle, exactly as 
in Hemiceras. Antennae of $ pectinated on half their length, palpi rather long. Only two species. 
Type of genus: S. lepidoides Dogn. 
S. lepidoides Dogn. Forewing brownish olive with a more yellowish oblique band from the first quarter lepidoides. 
of the costal margin towards the anal angle, another band in the distal half of the costal margin, a darker 
broad oblique shadow between them; transverse lines broken up into vein-dots, the posterior one extending 
almost into the apex. Hindwing blackish with lighter fringe and a stigma of almost the same colour. Peru. 
Expanse of wings: 46 mm.
