 Clytus Robinm. FORSTER. LOCUST TREE BORER. 



(COLEOPTERA, CERAMBYCID^.) 



This beetle is often confounded with the hickory borer, 

 Clytus pictus Drury, being similar in general appearance 

 and color. 



The eggs of the Clytus Robinice, are deposited 

 in clusters in the trunk of the tree, and in a 

 short time are hatched and the grubs com- 

 mence boring into the bark, subsisting on the 

 soft inner substance until winter approaches, 

 when it bores into the centre, or heart of the tree, remaining 

 torpid until spring. The following June, the beetle 

 emerges, requiring one year for the full development of 

 the insect. 



When, as often happens, many borers are in one tree, 

 it becomes full of holes and very much weakened. Any 

 kind of wash that is offensive to the beetle and will serve 

 to keep the eggs from being deposited, applied to the 

 trunk of the tree will prove effective. 



Dr. Harris proposes whitewashing the trunk of the tree, 

 and watching for the insect and destroying them. This is 

 easily accomplished, since they are frequently seen basking 

 in the sunshine on the bark. 



Xyhutes Robinice. PECK. LOCUST TREE CARPENTER MOTH. 

 (LEPIDOPTERA. BOMBYCID^E.) 



The larvse of this moth bores into our Locust trees, 

 arid although it is not found in the same number as the 

 Clytus, it is much larger and longer lived in the tree, and 

 much damage is done by them. They are nearly three 

 inches long, when fully grown, and about as thick around 

 as the end of the little finger. In color, it is reddish 

 above, and white beneath, sparsely covered with short 

 hairs arising from minute-warts. " These caterpillars bore 

 the tree in various directions, but for the most part 

 obliquely upwards and downwards through the solid
