PHALOESIA; HYALURGA. By Dr. M. Hering. 
interrupts Ct. interrupta sp. n. Basal spot of the forewing ochreous-yellow, abdomen like in the preceding, 
but the yellow lateral stripes in the centre very much narrowed or interrupted. Hindwing with two hyaline 
subapical spots, which equal the very large other subapical spots of the forewing in size. Dominica (Antilles). 
B type in the Tring Museum. Expanse of wings: 25 mm. 
subcyanea. Ct. subcyanea Wkr. Abdomen with red lateral stripes, basal spot of the forewing red. Length of forewing: 
20 mm. Patria unknown. — This species and the two following were not before me. 
agrius. Ct. agrius F. Abdomen with yellow lateral stripes, forewing without the red basal spot. Surinam. 
butus. Ct. butus F. Body beneath and the whole of the abdomen yellow, anus blackish. Wings uni-coloured. 
South America. 
21. Genus: Plialoesia Wkr. 
From all the genera hitherto dealt with exhibiting 1 spur on the hind tibiae, it is distinguished by the 
3rd radial in the forewing rising before the 5tli. 
sane ia. Ph. saucia Wkr. (= chalybea Btlr., fulvicollis Btlr., venezuelae Btlr., gentilis Bsd.) (65 a). Body 
black, metallic; collar, lateral lines of abdomen, and lateral spot of thorax red or ochreous-yellow. Abdomen 
beneath sometimes with 2 rows of white spots. Also the base of the patagia is often yellow or red. Wings 
blackish-brown, with a violet reflection, forewing with a red costal streak at the base, behind it a similar spot 
a little behind the costa. In the centre of the cell a row of yellowish-white spots from the costa to the posterior 
edge of the cell at most, a similar one of five spots before the apex. Colour and shape of markings variable. 
Hindwing more dark blue, with white fringes. The marks of distinction, stated by Butler, are merely individual 
differences. — Larva: head blackish-blue, body dark ochreous, with bluish-black tubercles forming transverse 
bands, double black streaks on the segmental indentations and similar small irregular dots, a continuous 
subventral stripe. Hairs black, partly white on the subdorsal tubercles of segments 3 and 4 and on tubercle 
3 on segment 12. Pupa in an open yellow network, light brown with numerous bluish-black dots and streaks 
on the wing-sheaths. Mexico to Venezuela. 
rubriplaga. Ph. rubriplaga Dgn. remained unknown to me, it probably does not belong hereto. Wings of a deep 
blackish blue, lustrous, with four longish red spots, three of which are at the base, the fourth between the 5th 
radial and 1st median somewhat distally to the cell. Fringes and body bluish-black. Expanse of wings: 40 mm. 
Peru. 
22. Genus: HyalllF^a Hbn. (inch Lauron, Laurona Wkr.). 
(Gyara Wkr., Cletorna Bsd.) 
Hind tibiae with 1 pair of spurs, in the forewing the radials 2 to 5 forked, in the hindwing the 3rd 
median and 1st cubitus not forked, in the forewing the 2nd radial rising before the 5th, in the hindwing 
the distance from the 3rd median branch to the 1st cubitus is less than double the distance of the 2nd median 
branch from the 3rd. — The smaller and darker species of Hyalurga, which were described as Lauron, strikingly 
look like certain Dioptids, but they are easily discernible by the veins.

■ fenestra. H. fenestra L. (= fenestrigera Hbn., egeon Cr.) (65 a). Head and thorax black, collar with 2, thorax 
with 6 white spots. Patagia ochreoiis-yellowT'often edged with blackish-brown. Abdomen above ochreous- 
yellow, the first and last segment white, with a black dorsal line and black subdorsal lines, the lateral lines 
and ventrum being white. Wings whitish hyaline, all the margins of the forewing varying from ochreous to 
reddish yellow, on both sides narrowly or more broadly edged with black; a similar transverse band extends 
across the transverse vein to the tornus where it bends towards the base. Veins blackish-brown. Hindwing 
with white veins and a black, more or less white-filled apex and distal margin. The transverse band is 
supposita. rarely quite black: —- supposita form. nov. ($ from Ucayali in the Berlin Museum), so that the species then 
resembles sixola Schs. (65 b), distinguished by the differently coloured abdomen and the broader band of the 
amazonica. hindwing. —- The form amazonica Btlr. has deeper reddish-yellow margins which are more broadly edged with 
black, and the distal margin of the hindwing only shows traces of the white filling. The form occurs with 
transitions among the typical form. South America to South Brazil and Peru. 
dorsilinea. H. dorsilinea sp. n. (65 a). Head and thorax black, head and collar with white spots, patagia red- 
brown, edged with blackish. Thorax behind with a large red-brown dorsal spot before which and at the sides 
of which there are white spots. Abdomen white, with a red-brown, black-edged dorsal line, a similar subdorsal 
line and lateral line. Forewing similar to fenestra, but the transverse-band only black, in the centre strangulated 
or interrupted. The black inner borders of the red-brown marginal line are broader. Hindwing in the black 
marginal area with a red-brown line, before the apex a black subapical band connecting the costal-marginal 
and distal-marginal bands, the part of the hyaline area, which is thereby cut off, is very small, 2 mm long, 
1 mm at most broad. Veins also in the hindwing blackish-brown. $ type from Cumbase in the Berlin 
Museum (Garlepp).
