HYLESIA. 197 
8. Hylesia alinda, sp. n. (Tab. XX. fig. 8, 3.) 
Male. Primaries pale pinkish fawn-colour, crossed about the middle from the costal to the inner margin by 
two bands of darker brown, a brown spot at the end of the cell and a waved submarginal pale band 
beyond; the underside as above, but the markings much more indistinct ; secondaries pinkish fawn-colour, 
with two indistinct submarginal lines: head and thorax pinkish-brown ; antenne and abdomen yellowish ; 
legs pinkish-brown. The female is similar to the male, but rather paler in colour and with the markings 
less pronounced. Expanse, ¢,2 inches; 9, 23 inches. 
Hab. Guatemata, San Gerénimo (Champion); Panama, Volcan de Chiriqui (mus. 
Staudinger). 
The specimen of the female from Chiriqui differs considerably in colour from our 
male example from Guatemala; it is very much browner, and has not the pinkish 
shade, but in other respects it is almost identical. 
This species is allied to Hyperchiria continua, Walker. 
4. Hylesia acuta, sp.n. (Tab. XX. figg.1¢, 29.) 
Male. Primaries pale brown, with a pinkish shade on the central part, the apex and part of the outer margin 
shaded with dark brown, a dark brown patch close to the base on the inner margin; secondaries pale 
brown, slightly darker at the apex, the base yellowish-brown, a small dark brown spot at the end of the 
cell: head and antennez pale brown; thorax and the base of the abdomen dark brown; abdomen and anus 
yellowish-brown ; legs dark brown. male. Primaries pinkish-brown, the base, a spot at the end of the 
cell, and a wide band beyond crossing from the costal margin near the apex to the inner margin dark 
brown; secondaries uniform pinkish-brown, with a darker mark at the end of the cell, the base of both 
primaries and secondaries clothed with long dark brown hairs: head, thorax, and abdomen dark brown, 
thickly clothed with pale yellowish-brown hairs. Expanse, g, 2 inches; ? 22 inches. 
Hab. Norta Mexico (tn mus. D. & Staudinger). 
I received, some years ago, a fine series of both sexes of this species from Northern 
Mexico, but do not know the exact locality. Dr. Staudinger has a male specimen, also 
without locality. H. acuta is a very distinct species. 
5. Hylesia (2) lineata, sp.n. (Tab. XX. figg.43, 52.) 
Male, Primaries pale brown, crossed by two dark brown lines which are edged on the inner side with pale 
fawn-colour, a submarginal waved line extending from the apex to the anal angle, a dark brown spot at 
the end of the cell; underside pale fawn-colour, slightly reddish at the base and along the costal margin, 
a round black dot at the end of the cell, beyond which is a dark brown line crossing from near the apex 
to the inner margin ; secondaries pale fawn-colour, with two dark waved submarginal lines extending 
from the apex to the inner margin, a dark red spot bordered with black at the end of the cell ; underside 
fawn-colour, palest near the base, and crossed in the middle by a dark brown line: head and thorax pale 
brown ; abdomen yellowish-brown, banded with black; antenne and legs pale yellowish-brown ; antenne 
of the male deeply pectinated, those of the female simple. The female is much larger than the male, of a 
more reddish-brown colour, with all the markings similar but very indistinct. Expanse, ¢, 14 inches; 
@ , 24 inches. ; 
Hab. Costa Rica (Van Patten), Irazu 6000 to 7000 feet (Rogers). 
This insect is not nearly allied to any known to me; I am a little doubtful if it 
should be placed in Hylesia, the secondaries of the males being rather longer than 
in any other species of the genus known to me. The female, however, agrees well with 
the same sex of Hylesia.
