Acanthoderes decipiens Hald. 



A rather stout, blackish beetle irregularly marked with gray, may be taken in June 

 on poplar and hickory. 



This insect was met with on poplar at Karner, June 18, 1902, and 

 appears to be a somewhat rare species in this section. Dr J. B. Smith 

 records taking this species in New Jersey on dead hickory in May. 



Description. It is a rather stout beetle, about Y / 2 inch long, black, 

 irregularly marked with gray, with annulate antennae 

 about the length of the body. The thorax is wider 

 than long and with a prominent tuberosity on each 

 side. The elytra are nearly truncate anteriorly and 

 bluntly spined posteriorly. This species may be sepa- 

 rated from its allies, according to Leng and Hamil- 

 ton, by the maculate white pubescence on the body ;

 out a whitish space, each bears a distinct M-shaped, black mark behind the 

 middle, and the base is irregular, with an oblong, obtuse umbone at its middle. 



Distribution. This species has been recorded by Messrs Leng and 

 Hamilton from Massachusetts, New York, New Jersey, Pennsylvania, Vir- 

 ginia, Georgia, Louisiana, Nebraska, Ohio, Canada and Maine, and it has 

 been listed from the District of Columbia, by Ulke. It has also been 

 taken by Zesch and Reinecke in the vicinity of Buffalo, and is recorded in 

 Dury's list of Coleoptera, from near Cincinnati O.
