Although the primaries of the male P. asetria and of 
this species much resemble the species of Lymantria, 
they differ in being less produced at apex; the female 
of P. asetria also has the elongated narrow-winged 
character of typical Porthetria. 
23. Dasychira argentata, n. 8. 
3. Most nearly allied to D. abietis of Kurope; greyish 
fuliginous; the primaries shining; the basal third and 
external border silvery whitish; the whole surface of the 
wing crossed much as in D. abietis by zigzag or undu- 
lating blackish and grey parallel lines, of which the most 
prominent are those limiting the basal area and the 
external border; disco-cellulars black and angulated as 
in D. abietis; secondaries whitish towards the base; the 
disco-cellulars and a broad externo-discal belt dark 
greyish ; thorax greyish white, the collar with a greenish 
tint; a spot on each shoulder and a band across the 
metathorax black; antenne whitish, with long rust-red 
pectinations; abdomen whity brown; under surface of 
wings whity brown, with disco-cellular spots and a 
discal belt grey; body almost pure white; expanse of 
wings, 1 inch 11 lines. 
Yokohama (H. Pryer). 
Although I have noted D. abietis and D. argentata 
here as species of Dasychira, they differ from D. pudi- 
bunda (the markings of which are wholly dissimilar) in 
their more woolly thorax, and in their thick woolly 
wings, in which the veins are much less conspicuous; 
the pattern of the primaries is of a different character ; 
in all these points of difference they correspond to 
“ Teara”’ rotundata, Wlk., of Australia, with which they 
may be associated as a new genus under the name of 
Calliteara. 
The Dasychira fascelina of Europe differs in neuration 
from D. pudibunda, the difference being especially notice- 
able in the male sex, in which the second and third 
branches of the median vein of the secondaries are 
emitted from a long footstalk; this species and D. 
leucophea of Georgia may be separated under the name 
of Dicallomera.
