may rest. The larv£E pupate within the beans, first gnawing a circular 

 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 brietly, 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, Megalopygidas, includes but live 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 i 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 pupa; 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
