 of Br aeon pissodis Ashm. from specimens of this insect received 

 from Wellesley Mass. Dr A. D. Hopkins has also obtained Spathius

Pissodes dubius Rand. 



A small, brownish, yellowish, flattened, long snouted beetle about i/,6 inch in 

 length, may be met with on spruce in July. 



A single specimen of this interesting insect was taken on spruce July 4, 

 1903, at Big Moose N. Y. 



Description. The beetle is about ? ,0 inch in length, brownish, with 

 the thorax and wing covers flaked with golden, creamy yellow scales, with 

 here and there a bunch of variable size. The thora.x is very coarsely, 

 almost contiguously punctured, and the wing covers are closely striated 

 with a series of nearly contiguous punctures. It may be separated from 

 I'ts ally, P. affinis Rand., according to Dr LeConte, by the sides of 

 the thora.x converging a little near the hind angles, which thus become 

 somewhat obtuse. There is also some difference in the scales on the 

 elytra, which, in w^ell preserved speciinens are more diffuse with the 

 markings less definite. 



Distribution. This species has been recorded from Lake Superior, 

 Canada and New Hampshire, and Randall states that he found it on a 

 wharf in Boston on pine wood brought from Maine.
