at first glance seems to fall in with obesiis and populi, rather than with 

 pyri and minor. A careful examination will place the species in BB 

 ("The elytra with the sides behind and the caudal margin evenly 

 arcuate") where the insect undoubtedly belongs. Length, 3.25 mm.; 

 width, about 2 mm. 



Black or brownish black, the antennae, tibiae and tarsi reddish 

 brown. Front plano-convex, punctured, sparsely hairy, the epistomal 

 fringe not well developed and the median carina fairly distinct. Pro- 

 notum sparsely hairy, slightly broader than long, asperate in front, 

 nearly smooth, shining, sparsely punctured and finely reticulate behind, 

 the posterior margin truncate; disc subopaque and finely reticulate. 

 Elytra hairy, the hairs slender, moderately long and arising from the 

 interspaces. The declivity with the striae inpressed, the interspaces 

 broad, the strial punctures not widely separated, the interstrial punc- 

 tures sparse. The declivital ridge of the seventh interspace acute, 

 slightly sinuate, but without teeth or tubercles. Interspaces slightly 

 elevated, uniseriately granulate-punctate. 



Afale: Very distinct. It falls in Swaine's key* to the males of the 

 genus Anisandrus with obesus and populi (B"The pronotum without 

 asperites, at most with minute granules") having a somewhat shining 

 pronotum. The pronotum and head are much smoother and less notice- 

 ably punctured than in either of the above species. Length, LG to 

 about 2 mm. 



Head slightly convex in front, not very closely punctured; epistoma 

 somewhat depressed, more densely punctured, with the usual fringe 

 of hairs. Pronotum slightly wider than long, beset with long, slender 

 hairs, with the granules on the cephalic portion almost entirely wanting, 

 much smoother and more closely punctured than closely related species, 

 subcircular in outline. Elytra with the strial punctures sparser and the 

 interstrial punctures finer than in populi and obesus, a little wider than 

 the pronotum, the hairs on the disc almost as long and dense as about 

 the margin of the elytra. 



Described from 6 males and 25 females, taken in hard 

 maple and beech during July and August, 1919 and 1920, at 

 Wanakena and Cranberry Lake, N. Y. The specimens collected 

 ■during 1920 by Mr. A. E. Fivaz and the writer were in a weak- 

 ened beech tree. Dryoccetes hetulce Hops, was also found breeding 

 in the same beech tree by Mr. Fivaz. One burrow, containing 

 living adults, was found in a dying yellow birch tree on Buck 

 Island, Cranberry Lake. The work of A. swainei is quite 

 similar to A. obesus and is found in both trunk and larger 

 branches. Type (female) and allotype (male) in my collection. 

 Paratypes in the collections of Dr. M. W. Blackman, Dr. J. M.
