may rest. The larvae pupate within the beans, first gnawing a circulai 
thin place through which the moth may push its way out. Another Tor- 
tricid moth, Grapholitha sebastiance , has similar habits. Most of the jump¬ 
ing beans come from the Mexican province of Chihuahua.

A few moth families, represented in this country by but few species, may 
now be referred to briefly, chiefly for the sake of mentioning certain par- ’ 
ticular forms that are fairly common and wide-spread and hence likely to 
be taken by the collector. 
The flannel-moth family, Megalopygidae, includes but five North Ameri¬ 
can species, of which the crinkled flannel-moth, Lagoa crispata , pale straw- 
yellow, with long, curling, woolly, 
brownish and blackish hairs, with 
wing expanse of about 1 inch, is 
not uncommon in the north Atlantic 
states, while Megalopyge opercularis, 
of about the same size, with yel¬ 
lowish-white fore wings overspread 
except at the tips by woolly purplish- 
brown hairs, is not uncommon in 
the southern states. The flannel- 
moth caterpillars have seven pairs 
of abdominal prop-legs instead of five, the number common to almost all 
other caterpillars, and the cocoons in which the pupae lie have a hinged 
door for the exit of the moth. The larva of M. opercularis looks like an 
animated bit of cotton-wool or lock of white hair. That of L. crispata 
feeds particularly on blackberry, raspberry, and apple; it is nearly oval 
in shape, covered with evenly shorn brownish hairs, which form a ridge 
along the middle of the back. When about f inch long it ceases to feed
