56 NORTH AMERICAN INSECTS. 
issuing from them immediately bore holes into the trunks 
of these trees, making winding passages through them, and 
feeding exclusively on the wood and pith. These insects 
continue in the condition of grubs only about a year, they 
being metamorphosed into perfect Beetles in the following 
September; but while in this transition state they are very 
active, and the destruction of locust-trees by them is very 
considerable. 
Dr. Harris, of Cambridge, in his Report on the Injurious 
Insects of Massachusetts, speaks of this Beetle particularly 5 
and the late Thomas Say, in his American Entomology, 
Table 53, represents four new species, which he calls Clytus 
speciosus, C. hamatus, C. undulatus, and C. caprea. 
We have now comparatively little to fear from the ray- 
ages of noxious insects, since our prudent Legislatures have 
enacted laws for the protection of birds, the great destroy- 
ers of insects, and it is probably on this account alone that 
many species of insects injurious to vegetation have almost 
entirely disappeared. In my travels through several States 
I have not, for the last two years, met with any of the Rose 
Bugs (Macrodactylus subspinosus), so destructive to every 
flower, nor with any of the Spotted Rutela (Rutela punciata), 
so injurious to the grape-vine. Even the May Beetles 
(Meloloutha quercicula) are not seen in such abundance as in 
previous years, and, should the laws for the protection of 
birds be much more strenuous, I fear our poor entomologists 
will be entirely thrown out of employment. It is a matter 
of congratulation, however, that our favorite birds are so 
well protected by the laws of some of our States, and by 
the general consent of the people. “They are more to be 
admired, even for their beauty, than most of our noxious 
insects, and certainly reward us by saving our trees and 
shrubs, and by furnishing us a wholesome and palatable 
article of food.
