hindwing quite straight. <$ antennae bipectinate, $ filiform. Veins of forewing as in Gamelia, but in both wings 
the cross-vein extends very obliquely in a straight line from above inside to below outside; on the hindwing 
6 and 7 comes from the upper cell-angle. 
C. bisfrigata Btlr. (112 a). Pale straw-coloured, in the more intensely, in the £ less strewn with olive bistrigata. 
brown, from the apex to the base of the inner margin a blackish longitudinal line above bordered with yellowish- 
white, slightly flawed at the lower cell-angle, and a double straight subterminal line filled with white. Hind wing 
of $ similarly coloured, of $ more reddish ochreous with a black central dot and a blackish postmedian line 
flawed above 6. Chile. 
10. Genus: Hrohylesia n. g. 
Connects Ancistrota with Hylesia ; in general of a structure similar to that of Ancistrota, the last palpal 
joint not drooping, but very feebly turned obliquely upward, longer than in Hylesia, antennae shorter than in 
Hylesia. in the bipectinate, in the <f> very short and thin filiform or set with short bristly hairs. Prothorax 
with a flatly compressed, comb-like erected tuft; abdomen shorter than hindwing, without the long hair of 
Hylesia. Veins of forewing exactly as in Ancistrota, hindwing with an almost hook-like projecting costal- 
marginal angle, especially developed in the $ (similarly as in Avtomeris flexuosa-mendosa). Veins likewise as 
in Ancistrota, but 6 and 7 not stalked, but together with 5 all three arise at equal distances, only in jriburgensis -$ 
6 and 7 arise from the same place of the upper cell-angle. 
Type: P. jriburgensis Sells. 
P. zikani sp. n. (112 b) <$ on the very light brownish ground shaded and strewn with a darker brown, zikani. 
with 2 fine dark transverse lines on the averted sides bordered with whitish, the anterior one vertical on the 
inner margin, the posterior one begins 5—6 mm before the apex and extends convergently to the former to 
the inner margin, where it is 2—4 mm distant from it; at the cell-end there is a large reniform light macula 
before which the cell is darkened brown; behind the postmedian line darker spotlike dusting; the subterminal 
line is irregular, with spotlike notches, blackish-brown. Hindwing dusted with red-brown, with 2 curved 
blackish-brown postmedian transverse lines, between and behind which the ground of the wing is lighter, the 
posterior line from the darkened apex; at the cell-end a light spot. The $ is uniformly suffused with 
chocolate-brown, with a pinkish lilac tint, the markings as in the A- Type: from Sa. Catharina, $ from Passa 
Quatro (Minas), Zikan leg., both in the Coll. Hopp. Co-type 1 $ from Sa. Cruz in the Senckenberg Museum. 
P. rosalinda sp. n. (112 a) is somewhat similar, of a light pinkish-brown ground-colour, the two transverse rosalinda. 
lines more distinctly dark brown, slightly undulate, not bordered with a lighter colour, of the discal spot only 
2 black dots at the upper and lower ends are visible, of the subterminal line only 2 black dots above the anal 
angle; before the cellular dots and behind the postmedian lines at the costal and inner margins some olive 
brown shading. Hindwing red-brown as in zikani, only the interior postmedian line more distinct, the exterior 
one rather indistinct. Thorax light yellowish-grey, the edge of the prothoracal comb darker brown. 1 £ from 
Passa Quatro, Minas, Brazil. Type in the Coll. Hopp-Charlottenburg; a more intensely dusted olive brown, 
from Leopoldina, in the Berlin Museum. 
P. friburgensis Schs. (112 b) was described as a Micrattacus. Head and thorax yellowish-grey, abdomen fribur gen- 
light reddish-brown. Fore wing yellow reddish-grey, strewn with black hair-scales, costal-marginal area above sis. 
the median vein and 4 dusted with light reddish-brown; transverse lines straight, whitish ochreous, distally 
shaded dark, the basal oblique line from the base of the costal margin, the antemedian line feebly excurved. 
the postmedian line slightly incurved, at the cross-vein a blackish-brown streak bordered with ochreous white; 
the light subterminal line extends sharply notched from 4 to the anal angle; costal margin grey. Hindwing 
light reddish-brown with a fine blackish-brown cross-vein shadow; behind the fine black distal line an irregular 
blackish-brown shadow; ends of fringes white. Forewing beneath yellow, at the costal margin red-brown. The 
5 is more intensely darkened olive grey, the transverse lines with a broader light border, the discal spot below 
widened in the shape of a hammer and filled here with deep black. Novo Friburgo, Bio de Janeiro. 
11. Genus: Hylesia Hbn. 
An uncommonly large and uniform genus, probably the most difficult item in the whole lepidopteral 
world, since it appears to have been impossible hitherto to separate the species by differences in the sexual 
armatures. Structurally it scarcely differs from Automeris. Chiefly small grey species, mostly thinly scaled, 
apex of fore wing often more or less feebly falcate. On the hindwing 5, 6 and 7 arise more distantly separated 
than in Automeris, the abdomen shows longer and coarser hair. Mr. Hopp-Charlottenburg, who has minutely 
investigated into the Hylesia, writes to me about them: It is rather very difficult to decide which is a species 
and which a variety, since there are no morphological differences whatever; some of the larvae, however, vary
