striated as far as the margin. Hindwing white, tinged with grey in the $, with rows of grey striae between the 
veins, which are more numerous and darker in the Expanse of wings: G 35, $ 46 mm. Argentina (1 ucuman), 
types in the U. S. National Museum. 
5. Genus: Caroliaiullia gen. nov. 
Areole long, triangular, 7 and 8 arise stalked from its apex, also 9; 10 close before it, and 11 near the 
base; discal vein plain, shortly forked only in one specimen. Discal vein of hindwing shortly forked, 6 and 7 
separate and parallel, 8 free. The type of the genus shows the anal veins of the forewing connected by a bar 
near the margin, while they are free in the other species. 
Type: C. ophelia Schs. 
C. Ophelia Schs. resembles a small dark-coloured H. terrafirma (181 f); basal area small, uniformly dark, ophelia. 
obliquely cut off, a small spot at the costal margin above the distinct discal dot; reticular markings fine, clear, 
grey, but not conspicuous. Guatemala. 
C. itys Drc. Dingy white, alternately grey and white between the reticular markings in the distal half; itys. 
a subbasal oblique black band composed of 2 confluent spots situate at the costal margin and in the submedian 
area; a similar spot at the distal third of the costal margin; the striae are distinctly connected reticularly, large 
and clear, uniformly scattered over the whole wing. Colombia. 
C. lineaplena Dgn. (167 g). Dingy white, the forewing densely striated black, not only between the lineaplcna. 
veins, but single striae cross them; hindwing not striated. In half of the specimens at hand veins 7 and 8 of 
the hindwing are connected by a bar which, however, is only delicate and not as in Zeuzera. The discal vein 
is mostly plain, in two specimens it is forked on the hindwing. French Guiana; Amazons (Obidos). 
6. Genus: Trigena Dyar. 
Veins 2—5 of forewing arise radially from the lower cell-angle; discal vein long-forked, the areole long, 
oval, its lower branch delicate, not projecting beyond the end of the 3rd discal cell; 7—9 stalked (or 9 connected 
with the base of the stalk); 10 arises from the areole and 11 from its centre. Cell of hindwing not notched, uni¬ 
formly rounded, all the veins separate, 8 free; discal vein long-forked. antennae bipectinated to the tips, 
those of the $ singly long pectinated to the tips. This difference of the sexes is very remarkable and induced 
me 26 years ago to place all the $$ to the genus Hemipecten Dyar, the S3 to Trigeiia. 
Type: T. parilis Schs. 
T. parilis Schs. (= ecparilis Schs.) (181 f). Forewing dark blackish brown with coarse black reticulations parilis. 
intermixed with finer ones; the coarse ones form a submarginal line which usually forms a loop or a circle at 
the height of the cell. Hindwing dingy white, reticularly striated brown in the <$, the $ tinged with a deeper 
brown. Brazil (Rio de Janeiro). 
T. horrifera Schs. Only the q is at hand, it is larger and darker than parilis (181 f), with somewhat horrijera. 
differently arranged reticular markings on the forewing. Brazil (Rio de Janeiro). 
T. crassa Schs. is exactly like parilis (181 f). Hindwing light, whitish in the disc, the coarse black reti- crassa. 
cular markings on the forewing more rectilinear, almost linearly arranged. Costa Rica and San Salvador. 
T. amarosa Dyar (181 b). Forewing dark lilac grey, the thick black striae form well marked subbasal, amarosa. 
median and subterminal lines. Hinclwing white, only the anal area feebly shaded. Mexico (Cuernavaca). 
7. Genus: Cossula Bailey. 
A considerable number of species with a variable neuration, similar to Trigena. All the veins may 
arise separately, or 7, 8 stalked, 8, 9 stalked, or 9, 10 stalked, but 7 is never stalked with 8 and 9 as in Trigena. 
The S3 have an enormously long frenulum thorn, half as long as the whole hindwing, extending into a noose 
of the subcosta of the forewing, while the $$ exhibit a small tuft of bristles. Antennae pectinated or bipectin¬ 
ated, but without a sexual difference, at least as far as one can judge from the ?? at hand. 
C. coerulescens Schs. (182 g). Blackish, with greenish white diffuse streaks in the submedian area, a coerulescens. 
fiery red spot traversed by darker veins in the marginal area, traversed by a curved black band. Hindwing 
black with an intense violettish blue reflection. Veins 7 and 8 of forewing distantly separated, arising from the
