LEPIDOPTEROUS INSECTS. 33 
Genus Nocrua, Fabricius. 
The antenne are setaceous, generally simple ; 
tongue long, horny, rolled up in a spiral form ; 
upper palpi very small, concealed, the two under 
ones bent, with the second joint very large, com- 
pressed, and furnished with scales, and the last 
very small ; body covered with small scales, the 
abdomen conical ; thorax frequently tufted ; wings 
sloping in the greater number. 
The insects of this genus, like all the other Lepidoptera, 
have their wings covered with a scaly dust, which is removed by 
the slightest touch ; the lower wings are plicated longitudinally 
on their internal side. They are commonly found in woods, gar- 
dens, and meadows, about the plants where the females deposit 
their ova. They fly abroad generally ahout sunset, remaining 
during the day concealed under leaves, on branches, or fixed 
upon walls. They couple almost as soon as they change from 
the pupa state. The male dies after coupling, and the female 
when she has insured the continuance of the species by the 
deposition of the ova. The species of this numerous genus 
are found on bushes and trees of various kinds. 
Famity V.—Torrrices, Latreille. 
Caterpillars some with fourteen, but the greater 
number with sixteen feet, the anal ones never 
wanting ; labial palpi sometimes short and eylin-

pointed, or in the form of horns. 
The caterpillars in this family roll themselves up in leaves or 
flowers, or live in the intorior of fruits. The wings of the in-
