brownish tubercles on the dorsum and a smaller patch on the 

 ventral side. The constrictions between the segments of the 

 body are deep and the elevated dorsal and ventral portions of 

 the first seven abdominal segments are roughened. The adult 

 insect or parent of this borer is a handsome beetle measuring 

 about an inch in length, the male beetle being considerably 

 slenderer and shorter than the female (Fig. 181). The whole 

 insect, appendages included, is clothed in a velvet-like coating

of fine, smoothly-laid hairs, giving it a very neat appearance. 

 The long antennae nearly as long as the body, and the legs are 

 gray. The head and ventral portion of the body are a beau- 

 tiful silvery white, and from the white face of the beetle two 

 broad, white stripes extend horizontally backward over the 

 head, across the thorax, and along each wing-cover to the tip. 

 The general color of the wing-covers and dorsal portion of thorax 

 is light brown, and the blackish eyes are very conspicuous on the 

 white head.
