16. Genus: Mhoclogonia Wan. 
Forewing straight at the costal margin, bent before the apex, apex pointed, distal margin with a 
small dent at vein 7, excurved at vein 4, oblique below it. Hindwing with a round apex, the margin angled 
at vein 4. Palpi erect, long. Neuration as in Rhodoneura. The first species, miniata, is only known as $, the 
other species, subfusca, was described from a Warren, however, is convinced that they are two different species. 
R. miniata Wan. (173 d). Wings yellowish ochreous with dense red reticular lines and a few dark brown miniata. 
spots, a larger one of which behind the cell is more prominent on both wings. The specimen figured, however, 
is red with fine dark striation. On the hindwing a brown shadow extends from this spot to the inner margin. 
Forewing beneath with traces of a median band which, however, is absent in the specimen figured. $ 36 mm. 
British Guiana. 
R. subfusca Wan. Reddish yellow with an olive brown shine, striated dark between the veins. Red subfusca. 
scales at the base and in the costal-marginal area. The costal margin itself snow white with 5 red dots in 
the basal half and 2 red blotches in the distal half, reddish brown at the apex. A dark spot at the cell-end. 
The fringe in the incurvations snow-white. Hindwing somewhat brick-red at the base, the distal half tinged 
with olive brown. A dark shadow from the cell-end to the inner margin. The costal and inner margins some¬ 
what yellowish. Beneath dark olive brown, more brownish ochreous on the hindwing. The inner margin broadly 
whitish on both wings. $ 35 mm. Cayenne. 
17. Genus: Hexeris Grt. 
Beside Risama Wkr., this is the only Thyridid genus in which the long palpi project horizontally. An¬ 
tennae of $ feebly serrate. Forewing with a slightly inserted costal margin, the distal margin slightly excurved 
at vein 3, all the veins free. Hindwing likewise somewhat excurved at vein 3. The genus contains but one species. 
H. enhydris Grt. (= reticulina Betd.) (174 e). The determination of the genus has caused great difficulties enhydris. 
to the two authors, and Grote fully describes the origin of the frenulum, but he does not mention anything 
about the family to which he would like to have his new genus placed, except the remark that it is very similar 
to the Geopnetridae. The wings are pale cinnamon brown with numerous dark reticular lines. Among them 
a median line on the forewing is more conspicuous, despatching a branch from the lower cell-angle to the costal 
margin towards the base. It is continued on the hindwing to the middle of the inner margin, a feebler branch 
extends from its apex at the costal margin dentately to the anal angle. 25—33 mm. A few species known from 
Florida, also from California. 
In the following genera the fore wing is more or less distorted, 
sometimes also the hindwing. 
18. Genus: Hepialodes Gn. 
Palpi short, porrect. Forewing inserted at the middle of the costal margin, irregularly cut off at the 
apex. Distal margin bent. Hindwing with 2 excisions at the costal margin near the apex. Neuration as in 
Rhodoneura. Only 1 species. 
H. follicula Gn. (174 e). Reddish brown, more or less tinged with violet, the intensity and number of follicula. 
the dark reticular lines being also variable. Forewing with a straight somewhat oblique median line, slightly 
forked at the costal margin. The cross-vein on the hindwing is distinguished by a tine silvery line, traversed 
by the dark somewhat bent median line. The reticular lines are just as variable as on the forewing. 55—75 mm. 
Guiana, Brazil. 
19. Genus: ISeloiiopterii H.-Schdjj. 
Both wings with a more or less pointed apex, the distal margin below it cut out. Type: phyllula Gn. 
The species differ from one another in the shape of the wings and the marking as much as the species of Draconia 
do. The two genera might be united. 
We begin with the two species in w h i c h the distal m a r g i n is rather 
much notched in both wings, as in the Draconia - species. 
B. nervicula Gn. (174 f). Ground-colour dark yellow with fine red-brown reticular lines none of which nervicula. 
is particularly prominent in my only specimen; there are only traces of one somewhat darker small triangle 
each marked by bifurcation at the inner margin, before and behind the middle. The lines which are rather fine 
everywhere are somewhat more densely arranged in the basal third. Hindwing with somewhat more prominent 
interior, median and submarginal lines. At the median line there is a large white spot in somewhat darker sur¬ 
roundings at the cross-vein. Distal margin notched at the veins in both wings. Anal angle of forewing pro¬ 
jecting far. Hindwing with a long apex at vein 7, another angle at vein 8, which is not so very prominent in 
the specimen figured from the Senckenberg Museum. The transverse lines are strong on both wings in this 
specimen. $ 62 mm. Peru, Brazil.
