INSECT NOTES. l8l 



The beautiful maple borer, Plaginotus speciosus, fig. 40, was 

 received from Monmouth the middle of July. The insect lays 

 its eggs about this time in the bark of hard maples and the 

 larvae bore into the wood. Their presence is made known in the 

 spring by the dust that is pushed from their tunnels, and the 

 borers can be destroyed by a knife and a wire, as in the case of 

 the apple tree borers. 



During the year a number of insects have been received 

 from correspondents for identification. A list of these with 

 notes is given in the following table. In addition to these, a 

 few other animals have been received and examined. These 

 include : Nematode worms, from salt cod fish. The flesh 

 bordering the alimentary canal was filled with encysted worms, 

 which were more than an inch in length. Millipedes. Numer- 

 ous in a cucumber house at York Corner, where they spoiled 

 most of the cucumbers. Trap door spider, Theraphosidce. 

 Received from Levant, though evidently a southern species.
