each other in the following respects : The antennae are long and tapering. 

 The body is oblong, approaching to a cylindrical form, a little flattened 

 above, and tapering somewhat behind. The head is short and armed 

 with powerful jaws. The thorax is either square, barrel-shaped, or nar- 

 rowed before, and is not so wide behind as the wing-covers. The legs 

 are long ; the thighs thickened in the middle ; the feet four-jointed, not 

 formed for rapid motion, but for standing securely, being broad and 

 cushioned beneath, with the third joint deeply notched. Most of these 

 beetles remain upon the trees and shrubs during the day tithe, but fly 

 abroad at night. Some of them, however, fly by 

 day, and may be found on flowers, feeding on the 

 pollen and blossoms. 



The pride of our Canadian forests, the Maple 

 tree, suffers much from the attacks of Clytus 

 speciosus (fig. 21), the largest of our native mem- 

 bers of the family. This beautiful beetle is easily 

 recognized ; it is about an inch in length, and the 

 third of one in breadth. The head is yellow, with 

 antennae and eyes of reddish black. In shape the Fi s- 2I - 



body is somewhat cylindrical, a little flattened above and tapering behind. 

 The thorax is black with two yellow transverse spots on each side. The 

 wing covers for more than half their length are black, for the rest they are 

 yellow ; they are gaily ornamented with bands and spots arranged as 

 follows : A yellow spot on each shoulder, a broad yellow curved band or 

 arch, of which the yellow scutel forms the keystone, on the base of the 

 wing covers ; behind this a zig-zag yellow band forming the letter W ; 

 across the middle another yellow band arching backwards, and on the 

 yellow tip a curved band and a spot of a black color ; the legs are yellow. 



The under side of the abdomen is reddish yellow, variegated with 

 brown The female has the advantage of her mate in size, but her 

 antennae are somewhat shorter. She possesses a pointed tube at the end 

 of the abdomen, through which the eggs are passed from her body into 

 the cracks and crevices of the bark. The tube can be contracted or 

 extended at the will of the fair owner and to suit the emergency of the 

 case. 



The parent lays her eggs on the bark of the Maple in July or August. 

 As soon as the grubs are hatched they burrow into the bark, and there 

 find protection during the cold of winter. When the warm days again
