LEPIDOPTERA.

We give a representation (in Figs. 237, 239, and 240) of the cases 

 of the caterpillars of three different kinds. The females of these 

 moths are completely destitute of wings, and resemble caterpillars. 

 As a general rule they hardly ever leave their case. The males 

 (Figs. 238, 242) are of a blackish grey, and fly very swiftly. 



The caterpillars of the genus Hepialus are difficult to observe, as 

 they live in the interior of the roots of various vegetables. Such is 

 the common Ghost Moth {Hepialus hiwiuli), which sometimes causes 

 the greatest damage. 



The type of the genus Zeuzeni is Zeuzcra lEsadi, or Wood 



Fig. 243.— Zeuzera aesculi. 



Leopard (Fig. 243). It has white wings with large blackish blue 

 spots on the anterior, and small black spots on the posterior wings. 

 The caterpillar, of a vivid yellow, spotted with black, lives in the 

 interior of the trunks of a great many trees, principally the chestnut, 

 the elm, the lime, and the pear tree. This moth, which is known 

 also by the name of Coquette, is to be seen in the evening flying 

 about the public gardens of Paris, and is not rare in England. The 

 most celebrated species of the allied genus Cossus is the Wood- 

 boring Goat Moth {Cossus ligniperda)^ figured in Plate VII. The 

 moth has a heavy brownish body and greyish wings streaked with 

 black. It is found in most parts of Europe. The caterpillar is of a 

 reddish colour, as if it had on a leathern jerkin, and disgorges a liquid 

 which is believed to soften ligneous fibres, and it Hves in the interior
