The body is somewhat depressed above, the thorax is prominently 

 longitudinally sulcate or channeled at the middle, and is gradually 

 narrowed toward the head, near which it is constricted. The head 

 terminates in a rostrum or snout, which is longer than the thorax. 

 Near the middle of the rostrum are inserted the elbowed and clubbed 

 seven-jointed antenna?. The femora or thighs bear each a tooth on 

 the ventral surface, and the claws are armed with a long, nearly bifid 

 tooth. 



The entire body of hibernated specimens is uniformly clothed with 

 a light-gray vestiture consisting of piliform scales, while newly bred 

 individuals, as was learned by the investigations of the season, are 

 coated with ochreous scales. The real color below the scaly covering 

 is black, and the older individuals appear leaden-gray in color and 

 the fresher ones fulvous. Such a difference in coloration imparts to 

 the insect quite a distinct appearance, so obvious that Dr. Dietz has 

 separated the fulvous form as a variety. The elytra are longitudinally 

 striate, as shown in the illus- 

 tration (fig. 12, a). A side 

 view of the insect, showing 

 rostrum and antenna?, is 

 furnished at !>. 



Full measurements give 

 the length, exclusive of 

 rostrum, at 2. 7 to 3. 25 mm. ; 

 width, 1.(3 to 2 mm.

The cabbage curculio is 

 evidently abundant in its 

 native home, its range extending through northern and middle 

 Europe.
