Desckiption of the Mature Insect.

The insect is one of the snout beetles or curculios, related to the plum curculio, but much 

 larger, being from 6.5 to 7.5 mm., about one-third to three-eighths of an inch, in length ; body 

 dull black with little spots or tufts of jet-black scales or hairs on the thorax and wing covers ; 

 scattered over the forward half of the wing covers are minute white scales which almost cover 

 the posterior third, and form a somewhat V-shaped marking between this and the thorax. The 

 body is coarsely pitted, and the femora, or first joints of the legs are spined. Plate, Fig. 1.

Distribution of the Species. 



The insect is common in Europe, ranging over Siberia and Japan, but whether it extends 

 further south into Central Asia is not known. In the United States it is known to oecur from 

 New Jersey to Massachusetts, and westward through New York and in north-eastern Ohio, 

 having without doubt pushed its way along the south shores of Lake Erie, from Buffalo, N.Y , 

 where it was first observed in the summer of 1896.
