in tlie males. The tongue and one pair of feelers are 
very distinct and of moderate length. The back is smooth, 
neither woolly nor crested, but thickly covered with short 
and close feather-like scales. The wings of many of the 
Lithosians are prettily spotted, and they frequently fly in 
the daytime like the Glaucopidians. Their caterpillars are 
sparingly clothed with hairs, growing in little clusters from 
minute warts on the surface of the body. They enclose 
themselves in thin oblong cocoons of silk interwoven with 
their own hairs. The rings of their chrysalids are gen- 
erally so closely joined as not to admit of motion. 
Of about a dozen kinds inhabiting Massachusetts, I shall 
describe only two. The first of these may be called Gno- 
phria vittata ,* 17 the striped Gnophria. It is of a deep 
scarlet color ; its fore wings, which expand one inch and 
one eighth, have two broad stripes, and a short stripe 
between them at the tip, of a lead-color, and the hind 
wings have a very broad lead-colored border behind ; the 
middle of the abdomen and the joints of the legs are also 
lead-colored. The caterpillar lives upon lichens, and may 
be found under loose stones in the fields in the Spring. 
It is dusky, and thinly covered with stiff, sharp, and barbed 
black bristles, which grow singly from small warts. Early 
in May it makes its cocoon, which is very thin and silky; 
and twenty days afterwards is transformed to a moth. 
By far the most elegant species is the Deiopeia Mia 
(Plate A I. Fig. 3), the beautiful Deiopeia. This moth 
has naked bristle-formed antennas ; its fore wings are deep 
yellow, crossed by about six white bands, on each of which 
is a row of black dots ; the hind wings are scarlet red, 
with an irregular border of black behind • the body is 
* I his moth 1ms nil the essential characters of the Enropoan Gnopliria rtihri- 
collhy nn insect closely resembling in its colors the Procris Americana. The namo 
o( the genus is derived from a Greek word signifying dusky, in allusion to the 
dark colors of the insects.
