APRIL. 67 



middle of the back, and three, more or less clear, long 

 streaks on each side. It attains eventually the length 

 of a Paris inch, but sits always in a contracted posi- 

 tion, and this, added to the unyielding nature of its 

 case, gives it a most deceptive resemblance to a hard 

 seed capsule or a little mass of flowers. 



" When about to go into the pupa state, it seeks a 

 hard flower-stalk, on the top of which, or sometimes 

 only high up thereon, it makes fast fragments of 

 flowers in the form of an open-work case, in which, in 

 about a day, it changes to a pupa, and within three 

 (seldom four) weeks it appears in the perfect state. 



" Light places in woods, plains and dry ditches in 

 woods, where the plants grow on which they feed, are 

 the favourite localities of these caterpillars. When 

 once one is discovered, several more may certainly be 

 found in that neighbourhood. The best season to seek 

 them is from the beginning to the middle of June, 

 when they have become full fed, and are approaching 

 their transformation. For this purpose it is not neces- 

 sary to use much apparatus, for if care be not taken 

 they are very easily deprived of their artistic cover- 

 ings." 



And now I have only to repeat that which I men- 

 tioned at the commencement of this chapter— Never 

 put off' till to-morrow the work of to-day ; but make 

 each day do its own work : for — 



" He who trusteth to the morrow 

 Soweth gold and reapeth sorrow."
