NATURAL HISTORY. 



ed. There are also flies tbat lay tbeir eggs among those 

 of the butterfly ; and thus the race, which otherwise 

 would be so numerous as to become a pest, is kept within 

 bounds by forming food for the larvae of bugs and beetles. 

 The butterflies are divided into four families : 



I. Hesperia, or Evening Moths. 

 II. Nocturnes, or Phalaena. 



III. Crepuscularia, Rovers. 



IV. DiurncB, or Butterflies. 



I. MOTHS (Blatta). 



These are small butterflies, which, avoiding the day, 

 are only seen in the evening ; have small and rather flat 

 wings, and but seldom provided with a proboscis. The 

 larvae come forth altogether unclothed, or covered with 

 almost invisible hairs ; they are, for the most part, cat- 

 erpillars of the grub order, and live concealed, perfecting 

 their metamorphosis in a cell of their own construction. 

 They are divided into three families, the Tinea, or true 

 moths, Leaf Rollers, and White or Candle Moths. 



I. MOTHS. 



These are the smallest of the race, with roof-like or 

 enveloping wings, which, horizontally spread, are covered 

 with a shining silvery dust. Their caterpillars make 

 galleries in portions of plants or dead animal matter, on 

 which they feed, or else construct, in a most skillful 

 manner, cases of silk, hair, or skin of leaves. They 

 undergo their transformation in these cases.
