LEPIDOPTERA. 213 
- Borys, Lat. 
These caterpillars are leaf-rollers, and do not differ externally 
from the others, as to their organs of respiration. 
B. urticata; P. urticatg, L.; Rees., Insect., I, Phal. XIV. 
Thorax and extremity of the abdomen yellow; wings white, 
with blackish spots, forming bands. 
Its caterpillar folds the leaf of the Nettle, and remains nine 
months in its cocoon before it becomes a nymph; it is naked 
and green, with a deeper stripe of the same colour along the 
back. 
The same plant nourishes the caterpillar of another spe- 
cies—the P. verticalis, L.—Rees., Ibid. I, Phal., 4, iv. The 
perfect Insect is pale-yellowish, glossy, with some obscure trans- 
verse lines most apparent underneath(1). 
Hyprocampr, Lat. 
This subgenus is composed of species very analogous to the pre- 
ceding ones, but their caterpillars are aquatic, and usually furnished 
with appendages resembling long hairs, inside of which are trachez. 
They construct tubes with various sorts of leaves, in which they are 
sheltered(2). 
Sometimes the proboscis is wanting, or nearly so, as in 
Actossa, Lat. 
Where the four palpi are exposed, and the wings form a flattened 
triangle; there is no emargination in the extremity of the upper one. 
A. pinguinalis; P. pinguinalis, L.; De Geer, Insect., II, vi, 4, 
12; Reaum., Insect., III, xx, 5, 11. Superior wings agate-grey, 
with blackish stripes and spots. Found in houses on the walls. 
Its caterpillar is naked, blackish-brown, glossy, and feeds on 
fatty or butyraceous substances. Réaumur called it the Fausse- 
teigne-des cuirs, because it also feeds on leather and the covers 
of books. It constructs a tube which it places against the body
