Mordella borealis Lee. 



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

 silvery white, occurs on spruce and decaying maple. 



This species may be recognized, according to I)r Smith, by 

 the short, truncate anal style, its dull lilack color, with ihe 

 thorax, pygidium and tlie elytra sprinkled with small, roundetl 

 spots of silver)' pubescence; wing covers with a narrow, 

 interrupted band, composed of confluent spots i)ehind the 

 middle. 



This species was taken on dying or recently killed spruce 



at lV\g Moose N. Y., July 2, 1903, by Mr Young, and he has 



also found it breeding in decaying maple stumps. This is 



tieUa bo'rl- cssentialU' a northern species, and has been recorded by Dr 



a 1 i s, enlarged ^ ^^ r TXTl L^ T-]l*ir 



(original) LeCoute, irom the Northern .States. It is also listed from 



the vicinity of Cincinnati I))- Dury. 



Dryocoetes autographus Katz. 



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

 be met with in siiruce bark. 



This l)orer was taken in considerable numbers under si^ruce bark at 

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

 LeConte, fn^ii its allies, l)y its larger size and the smooth front of the 

 strongly jjunctiireil 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 [jossible 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 Suj^erior, 

 Mount Washington N. IL, 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 til)ia in figure 118, 

 page 469.
