INSECTS AFFECTING PARK AND WOODLAND TREES 289 



and feet ferruginous ; a large spot on the middle of the prothorax and the 

 side margins are blackish brown ; upon the elytra the fifth interval from 

 the base to the middle is blackish brown, the color is then divided into two 

 branches, and prolonged obliquely to the suture ; the humeri are 

 ferruginous ; the rows of small acute elevations on the intervals 

 of the elytra have suggested the name of this species." Dr ^/^^^ 

 LeConte states that in well preserved specimens, beside the two |y^<^ 

 oblique bands behind the middle, there is a third one very near 

 the tip and with the sides of the elytra also dark colored. 



Distribution. Zimmerman records this species from the 

 Northern States and LeConte from Massachusetts to Texas, ''j'^^ '^'it,;^"^," 

 Kansas and Oregon. I)r Smith states that it is common in New 

 Jersey on cut ash and that it mines under green bark. 



Apple wood stainer 

 I\Ionarthriiiii iiiali bitch 

 A minute reddish brown, cylindric beetle, about )/(, incli in length, sinks small cylin- 

 dric galleries in dead beech, spruce and other trees. • 



This little borer was taken by the writer Aug. 21, 1900, at Flo(Kl\vood, 

 in a fallen beech which had begun to decay. It was also found by him on 

 the 22d at Axton, working in the stump of spruce 6 or 8 weeks after cutting. 

 This species was met with by Dr Intch in 1855, working in young thrifty 

 appletrees. He states that the attack is characterized by the trees putting 

 forth their leaves in the spring and then suddenly withering, as though 

 scorched by fire, the bark becoming loosened from the wood, and soon after 

 numerous pinlike perforations appearing in the bark of wood, from each of 

 which emerges an example of this beetle. He adds that he knew of the 

 insect only by specimens recently received from Middlefield Mass., from 

 Lawrence Smith, who states that he took them July 6 from the trunk of an 

 apple tree 10 inches in diameter, which was badly riddled by the burrows of 

 this insect. It is probable that the effects described above were the result 

 of some other agency since this species operates almost entirely in the 

 wood. Mr E. A. Schwartz has observed this species at work in red 

 oak at Washington D. C, and Dr LeConte states that it ranges from 

 Lake Superior to Florida.
