APPLE. TRUNK. 



forations like pin holes appearing, penetrating through the bark 

 and into the wood, from each of which comes out a very small, 

 cylindrical beetle, which is smooth, slender, black, sometimes dark 

 chestnut red, its legs and antennse testaceous or dull pale yellow- 

 ish, its thorax anteriorly minutely punctured, the declivity at the 

 tip of the wing-covers less abrupt than usual, with an excavation 

 or groove along the suture, which gives the apex a notched 

 appearance, and near the middle of the declivity upon each side 

 of this groove a slightly elevated tubercle of the shape of a cres- 

 cent, with its concave side towards the suture. Length 0.09. 



I only know this insect from specimens recently sent me from 

 Middleiield, Mass., by Lawrence Smith, Esq., who writes me that 

 he took them July 6th, from the trunk of an apple tree ten inches 

 in diameter, which was numerously punctured from the surface 

 of the ground to where the limbs commenced branching off, above 

 which no traces of them were to be found. In another letter he 

 states that this insect was first noticed in his neighborhood two 

 years ago, w^hen several nursery trees were riddled by them. 

 Nothing was seen of them last year; but they have reappeared 

 the spring of the present year (1857) in greater abundance, and 

 a number of trees have been ruined by them. I find a specimen 

 of this same insect also in a collection sent me several years since 

 from Ohio, by Dr. Robert H. Mack, of Parma. 



The joints of the feet and the contour of the antennae is the 

 same in tliis insect as in the genus Tomicus; but between the 

 second joint of the antennae and the knob or club is a mere cylin- 

 drical pedicel to the knob, scarcely as long as the second joint 

 and less than half its diameter, destitute of articulations cutting 

 it up into small joints. The antennae are thus but five jointed, 

 the knob being composed of only three nearly equal joints. And 

 I find no genus defined, the antennae of which strictly coincide 

 with those of tliis species. 



Pkar blight beetle, Scolytus Pyri. See Pear insects, No. 50. 



Several individuals of this species were also found by Mr. Smith, 

 associated with the foregoing, and coming out from the bark a 

 few days before them, making a perforation twice as large, the 

 holes of that species being })ut tliree-huudredths of an inch in
