Spruce wood engraver 



Pityoplit horns i-ariiiiccps Lee. 



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

 young dying red and Ijlack spruce. 



This minute form excavates many short, ratliatino-, curved -yalleries 

 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 IMorgantowa 

 W. V'a., and westward to Detroit ]\Iich., according to Dr Hopkins. Like 

 its allies, it is of comparativeh' little importance because its attacks are 

 confined to dying or dead trees, mostly limbs. 



Buprestis maculiventris Say. 



A large, metallic, flattened, oval beetle about ;'4 inch long, occurs on balsam in July. 



This species was taken on balsam at Lake Placid, |uly lo, 1903. 



Description. It is a brassy-brown beetle about ->4 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 

 [junctured 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. '
