76. Genus: Trichomoplata Wing. 
Like the preceding genus, but two thirds of the antennae pectinated, forewing still longer and narrower 
with a very pointed apex and an oblicpie distal margin; neuration the same as in Hemipecteros. 
Type of genus: T. vittata Wing. 
T. vittata Wing. (= tigniferum Fldr.) (150 a) is unmistakable; forewing yellowish-white, with a purple 
brown inner margin and a similarly coloured oblique band above it from the first quarter of the costal margin 
to the anal angle; the large very oblique reniform macula is at the cell-end, narrow black internerval wedges 
behind it. Hindwing white. Colombia, Peru and Bolivia. 
T. dimorpha Rothsch. (150 a). Forewing diaphanous dirty white, the basal half somewhat more 
densely scaled yellowish-grey, feeble shadowy bands of similar scales are subterminal and at the apex; a large 
orange brown spot is at the base of the lower median branch. Hindwing diaphanous white, yellowish-grey at 
the costal and inner margins. The much larger $ is more reddish-brown, only postdiscally diaphanous whitish, 
the dentate shadowy bands brownish, the spot is hemochrome, a rusty brown spot below it. Amazons. 
T. cassiope Schs. (= phronima Drc.) (150 a) is very similar to T. fifiana. Forewing light reddish-brown, 
crossed by 4 darker double zigzag lines, the most distal one shaded with smoky brown inside, a reddish-brown 
spot in the centre of the inner margin. Hindwing white, with red-brown hairs at the inner margin. Rio de Janeiro. 
77. Genus: Disphragis Hbn. 
This second-largest of all the Notodontid genera was formerly named Heterocampa Dbld. Some 
subordinate genera, such as Lochmaeus Dbld. and Cecrita Wkr., have been established for the numerous North 
American species, but in classifying the numberless tropical species this division cannot be well kept up, and 
so we must leave the grouping of the frequently very heterogeneous insects to a future exhaustive elaboration; 
we therefore keep to the large comprehensive genus in its original form. 
About two thirds of the £ antennae, often also of the §, are pectinated, the pectinations often very 
long, often much shorter, so that there is no distinct boundary to the strongly serrate shape; for this reason a 
few species the exterior of which entirely agrees with Disphragis were ranged under the genus Rifargia which 
is only distinguished by the shape of the antennae, as for instance gelduba. The hairy palpi are rather short. The 
neuration is quite the same as in Trichomoplata, the difference from the preceding genus chiefly consists in the 
less elongate shape of the wings with a less pointedly produced apex, the abdomen being somewhat shorter, 
too. The larvae have generally the normal shape without protuberances or cones, only several species exhibit 
in the early stage thorns shaped like a stag’s antlers on the first segment; the middle joints are often a little 
swollen, the claspers extended to long ends that can be turned out. As far as they are known, they live on all 
sorts of foliage-trees and pupate in a thinly woven cocoon between leaves. 
Type of genus: D. astarte Dbld. 
D. astarte Dbld. (= menas Harr., $ chapmani Grt.) (150 b) is very closely allied to all the following 
species. Forewing light olive green, with two double undulate black antemedian transverse lines, the space 
between them being often somewhat darker; at the cell-end there is a curved black crescentiform streak, a 
brownish-grey spot before it in the cell-end, followed by a threefold postmedian line with deep crescentiform 
bows, the two first distantly separated; the wing is subterminally lighter especially in the costal-marginal half, 
particularly in the and most intensely before the deep black undulate line; the marginal line composed of 
high crescents is very characteristical. Hindwing all white in the somewhat smoky in the $ with a darker 
marginal band and anal spot. The larva lives on oaks. The range is confined to Georgia, Florida, and Texas. 
D. varia Wkr. (= £ obliqua Pack.) (150b) is very near to astarte, but it lacks the olive green colour 
altogether, being brownish ash-grey, more or less mixed with reddish-brown; the white crescentiform subapical 
spot is larger, its distal black border broader, less distinct, enclosing short black internerval streaks, continued 
to the inner margin, and here with a small white lunule before it, the black marginal lunae are much flatter than 
in astarte, hindwing not so pure white, but somewhat smoky. — f. trouveloti Pack. (= brunnea Grt. & Rob.) 
is a more distinctly reddish-brown form, the female with some olive admixture and more prominent marking, 
hindwing smoky grey. — f. picta Fldr. (= perolivata Pack.) (150 b) is a form very similar to astarte, with purely 
light olive green forewings, but with the large white subapical spot and its distal broad indistinct border as in 
varia, and with purer white hindwings. — The larva is dirty whitish, flesh-coloured, brown or green with a white 
dorsal band which is expanded on the second ring and between the 4th and 8th rings, and edged by red-brown 
lines. It lives on oaks. It occurs in the Northern Atlantic States, the form picta in the Southern States.
