and accurately represented by tlie pencil of Lesueur, in Say’s 
“ American Entomology,” and, more recently, a description 
and figure of it have appeared in Griffith’s translation of 
Cuvier’s “ Animal Kingdom,” under the name of Clytus 
Hayii. 
The beautiful Clytus, like the other beetles of the genus 
to which it belongs, is distinguished from a Callidium by its 
more convex form, its more nearly globular thorax, which 
is neither flattened nor indented, and by its more slender 
thighs. The head is yellow, with the antennas and the eyes 
reddish black ; the thorax is black, with two transverse 
yellow spots on each side ; the wing-covers, for about two 
thirds of their length, are black, the remaining third is 
yellow, and they are ornamented with bands and spots 
arranged in the following manner: a yellow spot on each 
shoulder, a broad yellow curved band or arch, of which the 
yellow scutel forms the key-stone, on the base of the wing- 
covers, behind this a zigzag yellow band forming the letter 
W, across the middle another yellow hand arching back- 
wards, and pn the yellow tip a curved band and a spot of a 
black color ; the legs are yellow ; and the under side of the 
body is reddish yellow, variegated with brown. It is the 
largest known species of Clytus, being from nine to eleven 
tenths of an inch in length, and three or four tenths in 
breadth. It lays its eggs on the trunk of the maple in July 
and August. The grubs burrow into the hark as soon as 
they are hatched, and are thus protected during the winter. 
In the spring they penetrate deeper, and form, in the course 
of the summer, long and winding galleries in the wood, up 
and down the trunk. In order to check their devastations, 
they should he sought for in the spring, when they will 
readily be detected by the sawdust that they cast out of their 
burrows ; and, by a judicious use of a knife and stiff wire, 
they may he cut out or destroyed before they have gone 
deeply into the wood. 
Many kinds of Clytus frequent flowers, for the sake of the
