OCCURRENCE IN OREGON. 



On the occasion of a visit of Dr. A. D. Hopkins to the Northwest, 

 in April, 1899, adults and pupae were found on the 28th at Corvallis, 

 Oreg., in the bark and outer wood of the branches of dead apple, and 

 Professor A. B. Cordley, of the State Experiment Station located in 

 that town, stated that it was of common occurrence in such locations. 



INJURY IN BRITISH COLUMBIA. 



There is one record of injury by this insect, by Dr. James Fletcher, 

 published in the Report of the Entomologist and Botanist for 1898 

 (1899), page 207. He mentions receipt of specimens of apple boughs 

 containing the larvae of this insect from Victoria and Nauaimo, British 

 Columbia, with report from Mr. R. M. Palmer, of the former locality, that 

 these bark-boring larvae did much harm, especially in young orchards 

 on dry lands of the island. Many young trees were described as being 

 killed outright or so badly injured that they would scarcely recover 

 where preventive measures were neglected. Attack was also men- 

 tioned, on the authority of the Rev. G. W. Taylor, on Gabriola Island, 

 by the beetles feeding upon the leaves of cherry. This was noticed, 

 during two seasons, and hence may be considered a regular habit of 

 the beetles. Dr. Fletcher's name of bronze apple-tree weevil is adopted. 



DESCRIPTION OF THE SPECIES. 



The adult of this borer may be recognized by the accompanying 

 illustration (fig. 25a). It is rather remarkable in the structure of the 

 prothorax, the posterior 

 angles of which are promi- 

 nent and produced over the 

 base of the elytra, a char- 

 acter which it shares with 

 other species of the genus. 

 The beak is of about the 

 same length as the protho- 

 rax and the femora are 

 acutely dentate. The color 

 alone, black bronzed, will 

 distinguish the species from 

 others of the genus. 



LeConte's description 

 appeared in 1876 and was based upon material from Oregon (Proc. Am. 

 Phil. Soc, Vol. XV, p. 192). It is quoted herewith : 



Elongate, black bronzed, slightly pubescent; bead, beak and protborax densely 

 finely punctured, the last longer than wide, rounded on the sides, which are serrate 

 in front; hind angles small, prominent, base bisinuate, disk subcarinate in front of 

 the middle. Elytra obliquely impressed behind the base, and also behind the mid- 

 dle; stria? composed of not very large punctures, interspaces finely rugose. Meso- 

 sternum not protuberant; thighs acutely toothed, claws distinctly toothed near the 

 base.
