This insect, as the result doubtless, of the perils attendant upon its 



exposure to its inany enemies during its not closely- hidden winter's 



sleep, is never multiplied to such an extent as to give it rank among 



our serious insect pests; yet the caterpillar is frequently encountered 



in the latter months of the year, and often excites curiosity, as may 



appear from the following inquiry : 



Could you kindly give myself and others some information about 

 the caterpillars sent herewith? Just now they are crawling in all 

 directions, apparantly seeking warm quarters for the winter, as they 

 all appear to be wending their way towards buildings of some sort.
