Spruce wood engraver 



Pityophtkorus cariniccps Lec. 



A minute, black or brown beetle excavates many short, radiating, curved galleries in 

 young dying red and black spruce. 



This minute form excavates many short, radiating, curved galleries 



from a large central chamber, working in the bark and surface of the wood 



of twigs and branches of dying trees and stems of young, dying red and 



black spruce. This species ranges from western Maine to Morgantown 



W. Va., and westward to Detroit Mich., according to Dr Hopkins. Like 



its allies, it is of comparatively little importance because its attacks are 



confined to dying or dead trees, mostly limbs. 



Buprestis maculiventris Say. 

 A large, metallic, flattened, oval beetle about ^ inch long, occurs on balsam in July. 

 This species was taken on balsam at Lake Placid, July 10, 1903. 

 Description. It is a brassy-brown beetle about ^ inch in length, and 

 is easily distinguished, according to Mr Harrington, 

 by the reddish yellow ventral spots on each side of 

 the abdominal segments, and by smaller spots of the 

 same color on the anterior lateral margin of the 

 thorax. The prothorax is rather coarsely, irregularly 

 punctured and the wing covers deeply striated 

 (according to Harrington frequently rumpled), tips 

 almost truncate. 



Life history. Mr. Harrington states that this 

 species is common on both old and young spruce 

 trees in June and July, and adds that he has had the 

 beetles emerge from pine timbers about the end of June. 



Distribution. Dr LeConte states that this species occurs in Pennsyl- 

 vania, Lake Superior and Newfoundland.
