HYLESIA. By Dr. M. Draudt. 
to a great extent. Most of the larvae live gregariously in large nests from which they wander at night to the 
feeding place in processions, returning in the morning by the same way. There are also, however, without 
doubt Hylesia that lead a solitary life. 
In elaborating this genus I was most kindly aided by Dr. Sen aus- Washington, who was able to identify 
all the species before him. The National Museum of Washington contains the types of nearly all the species 
so that in this way they could he most reliably identified. Most of the new species were denominated by 
Schatjs. 
Type: canitia Stoll. 
Sect. I. Hindwing at least of <$ with an ocellus (Micrattacus). 
nanus. H. nanus Wkr. ( - dissimilis H.-Schaff.) (112 b). Forewing with a very falcately produced apex. Ground¬ 
colour of <3 copper reddish-brown, at the apex darkened, with fine yellowish transverse lines which are finely 
bordered with dark on the inverted sides, the anterior line undulate, interrupted towards the base below the 
cell, the posterior line almost straight, from about 5 mm before the apex, the subterminal area behind it 
somewhat blackish; at the cell-end a greenish-grey oval macula finely encircled and centred with dark. Hindwing 
in the disc darkened, with a yolk-coioured small ocellus with a fine darker, sometimes also fine orange red ring 
and tiny centre; the marginal area behind the almost straight postmedian line redder than the forewing. 
Abdomen rusty reddish, thorax in the middle and at the end deep dark brown. The $ is monotonously brownish 
or blackish grey, the markings arranged as in the <$, but slightly darker. Abdomen with ochreous hair. 
Colombia; Brazil; Bolivia. 
cortina. H. scortina sp. n. (112 b) is of the same shape, though larger, the ground light tan-colourecl brownish, 
at the apex dark violettish-grey, the transverse lines blackish-brown, fine, at the inner margin much nearer 
together than in nanus, the macula at the cell-end much larger, narrowly oval or feebly reniform, coloured like 
the ground, very rarely with a feeble greenish tint. Hindwing dark violettish-grey, in the marginal area with 
a rusty reddish hue, ocellus and lines as in nanus. Abdomen reddish ochreous. Brazil; Paraguay. Type in 
the Berlin Museum in Coll. Stgr. Numerous but no $ that might have been identified except perhaps 1 $ 
which resembles nanus-% on the wings excepting the much longer discal macula, whilst the abdomen is like 
that of corevia. 
corevia. H. corevia Sells. (112 c) has broader wings, a slightly falcate apex of the forewing, a most variable 
ground-colour, tan-coloured brownish, ochreous, red-brown or almost entirely violettish-grey, in the costal 
portion often greenish-yellow, marked very much like nanus, the anterior transverse line still more undulate, 
the discal macula of a very different size, mostly filled with yellowish-green or greyish-green. Hindwing as in 
nanus , but the ocellus more broadly surrounded with rusty red; mesothorax and metathorax varying between 
red-brown and black. Abdomen beneath red, with black bands. $ very large, purple blackish, discal macula 
and posterior transverse line broad, bordered and filled with black. Abdomen above black, laterally and beneath 
rusty yellow. A most variable species from Brazil. 
pyrrha. H, metapyrrha Wkr. (112 c) I should have considered to be the same species as corevia, judging from 
Walker’s description, but Tams writes to me with reference to it: “Nobody can give any information about it, 
Hampson has not discovered the type, and neither myself nor Lord Rothschild to whom I spoke about it 
can gather anything reliable from the description, I do not believe that it is the same as corevia .” $ light 
rusty brown, thorax with a posteriorly widened black median stripe; abdomen beneath bright red, with black 
bands. Forewing along the costal margin indistinctly tinted greenish, the roundish discal spot brownish-white, 
bordered with black and centred black; behind % of the length an oblique band, distally undulate, inside 
bordered with light, towards the apex obsolete, the apex itself blackened. Hindwing towards the inner margin 
purple blackish, at the distal margin reddish-yellow with a slightly undulate blackish band; discal spot almost 
round, yellow, indistinctly encircled with brown. Hindwing beneath purple violet, 1 ;j of the distal portion 
reddish-yellow with an oblique black band which borders on this colouring and separates it from the yellow, 
black-centred discal spot. Rio de Janeiro. This description exactly fits the figure of our d 1 from Passa Quatro, 
which, however, can by no means be specifically separated from corevia-<$, as all the transitions are present. 
line at a. H. lineata Drc. (= ondulatus Conte) (112 c) is distinguished from the similar species by the hindwing 
projecting angularly on vein 3; forewing light brownish, basally, in the costal half of the median area, subter- 
minally and in the upper half of the distal margin darkened blackish, with 2 light transverse lines, on the distal 
sides bordered with dark, often olive greenish, at the cell-end with a dark, white-centred ring; subterminal line 
in the upper half forming a bow which is concave towards the margin. Hindwing with a rather large carmine ocellus 
sometimes centred light and with a broad black ring, and 2 olive blackish lines behind it. The 2 is reddish-grey, 
the markings slightly darker, broader than in the the ocellus on the hindwing marked by a feeble ring. 
Abdomen ochreous, above black. Mexico to Costa Rica. 
6 aurea. H. subautea Sells. (= coadjutor Dyar) (112 c) is very similar, somewhat larger, more monotonously 
coloured, without the dark shading, the transverse lines bordered with a somewhat lighter, though not con¬ 
trasting colour, more olive green. Hindwing less angular, ocellus not round, but elongate. Mexico (Orizaba).
