long-lived, which accounts for its continuous presence; it 

 first appears in the early days of May and this brood con- 

 tinues some way into June, while the second brood appears 

 early in July and flies throughout August and sometimes 

 far into September. The eggs are shaped like sea-urchins, 

 and are very delicately reticulate with raised lines and pea- 

 green. The caterpillars feed on the heads of hops and on 

 the pods of beans, Cynoglossum and other plants; they 

 are very active when young and change their form con- 

 siderably, leech-like, when moving about. It is altogether 

 probable that the insect winters in the chrysalis.

This is a southern butterfly, flying about as far north as 

 the latitude of 42° and in the West a little further. It 

 seems to occur only in the vicinity of red cedars, on which
