234 JULY. 



as it were, before these little agents of supreme 

 power, and room is consequently left for Nature to 

 manifest herself once more in varied but generous 

 profusion. 



This class in England is comparatively small 

 about eighty species. They are found in old woods, 

 and in the stumps of trees. The Prionus coriarius 

 is the largest we possess ; and, unlike its congeners, 

 its flight is during the evening. Its larva inhabits 

 the oak. 



Zeuzera ^Esculi (the Leopard-Moth). A very 

 beautiful and interesting species, nearly allied to the 

 Goat-Moth, but of far less frequent occurrence. In 

 the larva state it inhabits the elm and pear trees, 

 and the perfect insect makes its appearance about 

 the beginning of July. It is of a snowy white, 

 spotted with round, greenish or bluish, spots; which, 

 together with its large size, soft, downy body, and 

 somewhat hyaline anterior wings, give it a very 

 delicate appearance. It has twice occurred near 

 Nottingham.
