96 SLUG-CATERPILLARS. 
FAMILY LIMACODIDZ OR SLUG-CATERPILLARS. 
A number of very interesting modest green or brown 
moths, usually of a small size, and very densely clothed 
with scales or hairs, form this family. They possess a much 
reduced head and have no tongue. The larve are very 
peculiar slug-like beings, usually flattened and oblong in 
shape, with no apparent legs; they move like slugs or snails, 
the prolegs being replaced by mere swellings on the abdom- 
inal segments. Some of these innocent or grotesque looking 
caterpillars can cause a burning pain like that produced by 
nettles; it is caused bythe breaking of certain hollow spines 
filled with a powdery dust or which contain the same urti- 
cating acid in a liquid form. 
THE GREEN SLUG-MOTH. 
(Parasa chloris H. Sch.). - 
The caterpillar (Fig.92, Plate X XII,) of this insect feeds 
upon cherry, apple and rose. It is of a bright scarlet color, 
with four dark blue-black lines along the back, and with 
prickly yellow horns or tubercles, which possess the power 
of stinging; the head is retractile. The ground-color of this 
caterpillar differs greatly, however, and in some cases it is 
yellowish or yellowish-brown. - Like most species of Lima- 
codide this caterpillar forms an egg-shaped cocoon, which 
is dark brown, smooth and very thin; in it the caterpillar 
hibernates, not changing toa pupa until 
spring. 
The moth is very pretty, have thing 
abdomen and hind-wings fulvous, the 
thorax and front-wings delicate green, the
