easily reared if taken when tolerably well grown. If 

 placed with some lichen in a jar covered with book- 

 muslin, they will thrive without any care beyond occa- 

 sionally damping the lichen, and preventing it from 

 growing mouldy. As they are caterpillars which rest in 

 exposed situations, they may be sought for during the day. 

 When full-grown they change to pupa in a web spun 

 among the lichen. 



The majority of caterpillars are nocturnal in their 

 habits, and must therefore be sought at night by the 

 light of a lanthorn. It is true, a few may be found amongst 

 plants, and under broad leaves, &c., in the day-time ; but 

 to obtain many, we must look for them whilst they are 

 feeding. Of course, we are speaking now of those only 

 which live on grasses and other low plants ; and these 

 must be sought for on banks and other places where the 

 vegetation is forward. When their evening meal is 

 finished, as if conscious of security during the hours of 

 darkness, they often crawl up to some exposed place on 

 the tall stem of a plant or bush, there to rest until hunger 

 or the morning recals them to the ground. All such 

 places must, therefore, be examined, as well as the 

 plants which actually form their food. 



In collecting and keeping caterpillars they must not be 

 crowded in too small a place, or they will sweat, become 

 enfeebled, and eventually die. Like most other beings 

 they require plenty of both air and room. When a 

 number of larvae are stored away in cages they must be 

 well suijplied with fresh food, or they will either not 

 arrive at maturity or come out small, dwarfish specimens. 

 They must also be furnished with those plants on which 

 they have been found feeding, since many would reject 

 other food and die of starvation. Some species are re- 

 stricted to one or two plants, others are found on one 

 genus or tribe of plants, whilst many feed on almost any-
