In one of these chambers I found this beetle, alive but dormant. The same axillary perfora- tions are abundant in young orchard trees set out last spring. Please give me the name of the specimen sent and informa- tion whether the perforations are the work of this beetle in some of its forms, or of some other insect.

The beetle sent by our correspondent is the common Apple-twig Borer (AiiiphiceTiis bicixuda- ttts Say). It is extremely common throughout the Western States, and is more often received for identification during the winter and spring months I I' .\pple twigs bored by A ntphicerics I'icnidlatus : f, entrance ; f/, burrow cut open. than any other beetle. Its habits being well de- scribed by our correspondent it suffices to say that it works not onlj' in grape canes but in the more tender twigs of apple, pear, and peach trees. Both sexes of the beetle bore these holes and may then be found in them head downward at any time during the winter and spring months, the holes being made both for protection and for food and not for breeding purposes. Indeed the breed- ing habits of the insect are not yet known with certainty ; for while Dr. Henry Shinier found cer- tain larv» in grape canes which he conjectured to be of this species (see Trans. Am. Ent. Soc. 1868, vol. II, p 9), yet they were doubtless those of an allied beetle {Siiwxylon basilare Saj') which I sub
