JULY. 209 



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 iEsculi, (the Leopard-Moth.) A 

 very beautiful and interesting species, nearly 

 allied to the Goat-Moth, but of far less fre- 

 quent occurrence. In the larva state it inha- 

 bits the Elm and Pear trees, and the perfect 

 insect makes its appearance about the begin- 

 ning 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 oc- 

 curred near Nottingham.
