 All the winter prunings should also be burnt. 



The Wood Leopard (Zeusera cescidi). The larva of 

 this and the following moth feed in the trunks of many 

 trees, including the apple, pear, plum, and walnut, 

 boring large holes into them, and often killing the 

 tree. The best method of killing them is to thrust 

 a strong wire up the hole, and if the end has wet 

 whitish matter on it when drawn out again, the larva 

 has been reached. Paraffin oil, tobacco water, &c., 

 may be injected up the holes with a sharp-nozzled 

 syringe. The brown pupae found in cocoons, made of 

 little bits of wood, at the mouths of the holes in May, 

 June, and July, should, be destroyed. The full-grown 

 larva of the present insect is about an inch and a half 

 long, yellow, with raised shining black spots. There 

 is a black homy plate on the segment behind the head, 

 and a black patch on the anal segment. The moth is 

 large and sluggish, and may be found on palings and 

 trunks of trees. Its wings have a span of two to two 

 and three-quarter inches, and are semi-transparent, 

 white with numerous blue-black spots, which are less 

 distinct on the hind wings. The thorax is white, 

 spotted with black, and the abdomen grey. 



The Goat Moth (Gossus ligniperda). The remarks 

 on the damage done by the larva of the last species 

 apply also to the larva of this. It is about three 

 inches long when full grown, and is a sort of dirty 

 yellowish or flesh colour, with a broad dark reddish
