employed which are scarcely ever found in cork doors, such 
as dead leaves, bits of stick, roots, straw of grasses, etc., 
and I have seen freshly cut green leaves, apparently gath¬ 
ered for the purpose, spun 
into a door which had re¬ 
cently been constructed.” 
We have in this coun¬ 
try a species of Tarantula 
(Lycosa) which as if by 
design covers its hole 
with a mass of dead and 
dry leaves, as indicated 
in Fig. 216 (after Emer- 
ton). In an article in the 
“ American Naturalist,” 
vol. iv, Mr. Emerton tells 
us that his attention was 
drawn to these nests by 
Mr. J. A. Lintner, who 
noticed on the sandy hills 
west of Albany, N. Y., a 
number of holes about 
half an inch in diameter, 
each surrounded by a 
ring of sticks and bits 
of leaves loosely fastened 
together by fine threads. 
The larvae of Cassida, |8ip 
the helmet beetle, and N '" 
Lema, which live exposed 
to the sight of their ene¬ 
mies on the upper side of leaves, afford examples of what, 
at some period in the life of the species, may have been a 
conscious attempt at deception. The larva of Cassida is 
broad, flat and oval, edged with long, sharp spines. By
