TRYGODES. By L. B. Prout.

T. physciata Feld. (11 g). Relatively somewhat broader-winged than most of the species, the green physciata. 
markings very characteristic. Midtibia of glabrous. Amazon. 
T. basisignata Prout (11 g). Much smaller, ground-colour paler, postmedian line more distally placed, basisignala. 
forewing with the green markings differently formed and a dark spot close to base. La Oroya, Carabaya, only 
the type $ known. 
T. ovipara sp. n. (11 g). Close to physciata in shape and structure, but distinguishable at a glance by ovipara. 
the small oval (or very slightly reniform) cell-marks. Peru: Tarapoto, Loreto (Mathan), only the type $ known 
(ex coll. Oberthur). 
T. spoliataria Moschl. (= columbaris Btlr.) (11 g). Variable above, but always with the green cell-spots spoliataria. 
small compared with those of most of the species; an indistinct subterminal shade, which becomes much stronger 
on the underside, is pretty constant and recalls that of the musivaria group. In the name-typical forms (Surinam 
and reaching Venezuela westward and the Amazon southward) the green spots are never intense, generally 
pale yellowish green, the antemedian wanting or extremely weak. —- ab. (? subsp.) accentuata nov. (11 g) has accentuata. 
the central green markings darkened, those of the forewing somewhat suggesting a “looper” caterpillar with 
its body strongly arched, the antemedian spot present. This is the prevailing form in Costa Rica, Colombia 
and the Chanchamayo district, but the two forms seem to meet in N. W. Venezuela and E. Colombia. Type 
from Chanchamayo (coll. British Museum, ex coll. Oberthur). 
T. dissuasa Prout (11 h). Almost exactly like a smaller spoliataria, well irrorated and nearly always dissuasa. 
weakly marked, but with the midtibia of the $ glabrous, whereas in spoliataria it is clothed with long dense 
hair; cell-mark of hindwing almost circular, on the underside wanting. This and some details of the position 
and course of the lines distinguish it readily from even the most weakly marked solanijerata. W. Ecuador: 
Quevedo and La Chima (Prov. de Los Rios). —- ab. maculifera nov. has small dark-green spots, those maculifera. 
of the forewing on each side of the 3rd discocellular with a dot in front of them (base of cellule 6). La Chima, 1 <$. 
T. glaucorrhanis sp. n. (11 h). Very distinct, superficially least unlike desolata but with the 3rd joint glaucor- 
of the palpus longer, the midtibia of the glabrous, the wing-margins less deeply dentate. More brownish, 
the markings weaker, the green markings all small and round, the two outside the cell of the forewing parallel 
with one another, not (as in the niobe group) nearly parallel with the termen. W. Ecuador (Mathan) in the 
Oberthur collection, the type from Balzapamba; the 5 (Balzapamba, La Chima and Chimbo) have 
some of the green spots dark, merely with pale edges. 
T. niobe Druce (11 h). Except from amphion (which see), this fine species is easily distinguishable by niobe. 
the arrangement of the green spots. Midtibia of d 1 , as also in amphion , strongly tufted. Costa Rica (type), 
Colombia and Peru. — desolata Prout, from N. W. and E. Colombia and Venezuela is a race, or perhaps separate desolata. 
species, with the spots smaller and of a very pale green. 
T. amphion Schaus (11 h). Closely like the most brightly coloured forms of niobe, generally larger; the amphion. 
spots considerably enlarged, the discoidal series on the forewing extending into the base of cellule 2. Costa 
Rica. A race(?) in Chanchamayo. 
T. viridiplena Prout (= musivaria Druce, nec H.-Sch.) (11 li). Much larger than musivaria, the green viridiplena. 
markings relatively larger, the midtibia of the as in the two preceding. Venezuela (loc. typ.), also from Panama, 
Colombia and Matto Grosso. 
T. musivaria H.-Sch. ( = herbiferata Guen.) (11 h). The commonest and most widely distributed Try- musivaria. 
yodes, recognizable by its small size, glabrous 3 midtibia and ample dark-green markings. A further charact¬ 
eristic of this species and the following is the strong inward bend of the subterminal of the forewing between 
the radials, with a conspicuous blackish dot pointing outwa r d on the 2nd radial. The type 
•was from Brazil, but the range extends to Costa Rica and Trinidad. The larva is smooth, moderately slender, 
green, with white lateral stripe and in Rio Grande do Sul is found, according to Mabilde, on a species of 
Angelica from October to December; pupates among leaves, the moth emerging after 10 days. 
T. solaniferata Guen. (12 a) is closely related to musivaria, possibly a recurrent form of the same; mark- solanifcra- 
ings, particularly the posterior spot of each wing, considerably reduced, generally much paler green. Brazil and tc 
Paraguay. ■—- herbida Oberth. (12 a) is an aberration or race with the green spots bright, though small. Cacliimbo herbida. 
(Bahia). •—- tarapotensis subsp. nov. (= merta Oberth. nec Druce) (12a) has the irroration reduced, giving it a tarapoten- 
very clean appearance, the green markings outside the cell of the forewing rather compact, the postmedian si ' 
line of both wings somewhat more distally placed than in solaniferata type. Tarapoto, E. Peru (Mathan), 8 d'cL 
1 $ from the Oberthur collection, the $ having the markings reduced. — merta Druce (12 a) is probably a merta. 
further race but, to judge from the few examples known to me, scarcely constantly distinguishable from solani¬ 
ferata unless by the shape of the group of green spots of the forewing. Guatemala (loc. typ.), Mexico and 
Honduras.
