to the length of an inch or more, are attached, like a broken corkscrew, 

 to the hark/' 



On cutting into the bark at this place you will find the -lender burrow, 

 probably running in an upward direction for aboul an inch, and the 

 young grub, of about one-fourth of an inch long, lying in its upper end. 



This is the most simple and effective way in which to arrest the inju- 

 ries of this destructive borer. It is far preferable to wrapping the 

 trunk with cloth during duly or August, or applying repellants for 

 preventing the deposit of the eggs, for, by the means above suggested, 

 the insect is killed instead of being driven away to other trees. 



The following notice of this insect is contained in the "Report of the 

 State Entomologist to the Regents of the University of the State of 

 New York, for the year 1886," but as only a few copies of this paper 

 were printed for distribution it is republished here, containing as it 

 does, some observations that have not been given elsewhere. 



A lady writing from Canajoharie, New York, complains with much 

 feeling of the ravages of a borer which is rapidly destroying some 

 highly valued maples which shade and adorn her home. 



From the account given of its operations, it is undoubtedly the maple 

 borer above named (Glycobius speciosus), which was first described 

 by Say in 1824, in long's Second Expedition to the Sources of St. 

 Peter's Rloer (ii, p. 290), as a rare insect. In addition to the speci- 

 men taken on the Wisconsin river during the expedition, one other 

 only was known, which had probably been taken in Pennsylvania, and 

 was in the possession of the Philadelphia museum. It was subse- 

 quently illustrated in Say's American Entomology. Dr. Harris has 

 noticed and figured it in his Insects Injurious to Vegetation, giving at 

 the same time one of those popular and graphic 

 descriptions which enable his readers to recog- 

 nize the insect unaided by illustration, and have \ 

 lent such a charm to his invaluable report. Of 

 later years the beetle has become comparatively 

 abundant, being found in nearly all collections. 

 and having been frequently written of by a 

 number of authors. It is one of our most 

 beautiful species, as its specific name of speciosus 

 (meaning beautiful) implies, being a member of 

 the family of longicorns (Gerambycidc) and / 



measuring over an inch in length, marked with FlG 45 _ Th

 of its wing covers. [See Figure 45, reproduced from Emmons.]
