Mordella borealis Lec. 

 A small, narrow, triangular beetle about 3 /,6 inch in length, irregularly marked with 

 silvery white, occurs on spruce and decaying maple. 



This species may be recognized, according to Dr Smith, by 

 the short, truncate anal style, its dull black color, with the 

 thorax, pygidium and the elytra sprinkled with small, rounded 

 spots of silvery pubescence; wing covers with a narrow, 

 interrupted band, composed of confluent spots behind the 

 middle. 



This species was taken on dying or recently killed spruce 

 at Big Moose N. Y., July 2, 1903, by Mr Young, and he has 

 also found it breeding in decaying maple stumps. This is 

 ""de'na b^ore- essentially a northern species, and has been recorded by Dr 

 ^rigina n i) arged LeConte, from the Northern States. It is also listed from 

 the vicinity of Cincinnati by Dury. 



Dryocoetes autographus Ratz. 



A small, stout, nearly cylindric, brownish bark beetle about j4 inch in length, may 

 be met with in spruce bark. 



This borer was taken in considerable numbers under spruce bark at 

 Big Moose N. Y., July 2, 1903. It may be distinguished, according to Dr 

 LeConte, from its allies, by its larger size and the smooth front of the 

 strongly punctured prothorax. He records this species from Alaska, 

 Canada and Virginia under pine bark, while Dr Hopkins states that it 

 occurs under green bark of logs and stumps of spruce. It is possible that 

 there is a mistake in the preceding record. This species evidently has a 

 wide distribution in the northern part of this country, since it has been 

 recorded from Alaska, Hudson Bay Territory, Canada, Lake Superior, 

 Mount Washington N. H., New Jersey, southwestern Pennsylvania, 

 Virginia and West Virginia. The peculiar structure of the proventriculus 

 is illustrated on plate 69, figure 9, and that of the tibia in figure 118, 

 page 469.
