shaped more like in the Noctuids, the thoracal subdorsal tubercles are not yet fused, but are inclined to it. 
First stage dull orange, the segments 5 and 6 and 9 to 11 reddish purple, tubercles dark; adult larva of a glaring 
pinkish-red colour with a violettish-blue reflection, scantily haired. Stigmata pale orange. On the segments 
2 to 5 the lowest two, on 5, 6 and 9 to 11 all the tubercles are blue. Pupa fastened with very few threads 
on the head and cremaster, reddish mahagoni-coloured, with blue and violet spots on the wing-cases. Foodplant: 
Echites umbellata and Canavalia obtusa. — As to the peculiar behaviour of the imago on being taken, discharging 
a yellow spume with a bubbling noise, cf. the introduction (p. 424). 
5. Genus: Xenosoina Fldr. 
In the habitus the germs resembles Coborisa ; it was hitherto referred to the Lymantriids from which 
it differs by the well developed proboscis, but it has 2 pairs of spurs on the hind tibiae. In the structure similar 
to Thyrgis, but the 1st cubitus in the hindwing about in the centre between the 2nd cubitus and 3rd median 
branch, and the cell of the forewing is behind more produced. Antennae in the 3 strongly pinnate, the pinnae 
towards the apex, however, more abruptly shortened than in Thyrgis. 3rd palpal joint just as long as the 2nd. 
X. progonum sp. n. (60 d). Head and thorax varying from wood-colour to an ochreous yellowish, progonum 
palpi darker. Abdomen white, anal tuft ochreous. Wings hyaline milky white, the distal margins with a blackish- 
grey, posteriorly narrowed border. Veins greyish-brown, behind the cell a blackish spot at the proximal margin. 
Costa and proximal margin of forewing more intensely dusted greyish-white. Beneath as above. Peru. $ type 
from La Oroya, Rio Inambari (3100 feet.) in the Tring Museum, $ type from Bolivia in the Berlin Museum. 
X. nigromarginatum Drc. is very much like progonum, the patagia white with a yellow basal spot, nigromargi- 
the black border on the 1st median branch in the forewing only 1% mm, in the hindwing 1 mm; in the $ of natum. 
progonum as much as 4 (in the 2) resp. 2 mm broad. Costa Rica. 
X. flavisedes Dogn. (60 d). Body whitish, head, collar, thorax below, patagia and 2nd palpal joint fiavisedes. 
and anal tuft ochreous yellow, 3rd palpal joint black. Wings quite whitish hyaline, at the margins, particularly 
before the apex of the forewing, more densely dusted with a somewhat greyish colour. Venezuela. 
X. flaviceps Whr. (= nigricosta Fldr.) (60 d). Body as i n jlavisedes. Wings quite milky white hyaline, fiaviceps. 
nor are the veins darker; costa of forewing narrowly black. Mexico to Venezuela. 
H. giganteum Drc. with whitish hyaline forewings exhibiting' a yellowish base and proximal margin, the abdomen 
beneath pale yellow, with an expanse of 65 mm, from Honduras, is probably a Lymantriid.

6. Genus: Pseuriophaloe gen. nov. 
Hind tibiae with 2 pairs of spurs (in Phaloe Guer. only 1 pair). In the forewing the 1st and 2nd radials 
are separate, the 3rd to 5th forked, the 5th before the 3rd; the 1st median branch from the same place 
as the fork. 2nd cubitus rising far before the 1st, the first portion of the posterior edge of the cell less than 
twice the length of the second. In the hindwing the radial ramus and the 1st median branch, as well as the 
3rd median branch and the 1st cubitus are forked. Length of $ antennal pinnae not quite attaining the 
thickness of the shaft. Type of the genus: Ps. verania Drc. 
Ps. verania Drc. Body blackish-brown, head and collar with white dots, the margins of the abdominal verania. 
segments narrow white, sides and last segment of abdomen are red. Wings blackish-brown, forewing with a 
red basal spot, a yellow median band, and a yellow subapical spot, hindwing with lighter yellow spots at the 
costa, behind the subcostal, behind the bifurcation of the radial ramus and 1st median, and between the 
2nd median and 1st cubitus. Beneath as above the veins at the base whitish; in the hindwing the spot behind 
the subcostal is towards the base extended to a stripe, a stripe below the anterior edge of the cell and 
2 or 3 bluish-white longitudinal stripes at the anal angle; distally to the latter 1 or 2 yellow spots. Mexico, 
Honduras, Guatemala. 
Ps. schausi Edw. is unknown to me in nature. It differs from the preceding by exhibiting beside schausi. 
the subapical spot of the forewing another spot in its prolongation at the centre of the margin. In the original 
description the red lateral stripes of the abdomen, which are present in verania, are neither mentioned. Mexico. 
Ps. helotes Drc. is similar to Ps. verani, the bands of both wings are brimstone-coloured, the subapical helotes. 
spot of the forewing in the $ smaller, only in one cell (in verania it extends to the 2nd, here to the 1st median 
branch). The yellow spots of the hindwing are broader, more closely together, no yellow spots in the anal 
portion beneath. Panama (Volcan de Chiriqui). 
Ps. stenoxantha sp. n. is allied to helotes, on the abdomen not only the last, but also the two preceding stenoxantha. 
tegments are beneath red. The centre of the other segments on the ventral side broader white; the band of 
#he forewing is only half the width of that in helotes, the subapical spot in front extending beyond the 5th radial.
