iDOLEOPTERA. 



detected this little weevil laj-iug its eggs in the buds of the 

 cranbeny. "It selects a bud not quite ready to open, and 

 clinging to it, works its snout deep into the centre of the bud. 

 An egg is then deposited in the hole made, when the beetle 

 climbs to the stem and cuts it off near where it joins the bud, 

 which drops to the ground and there decays ; the egg hatching 

 and the grub going through its transformations within." The 



larva is long and rather 

 ^/^~\ slender, cylindrical, the 

 l)ody being of uniform 

 thickness and curved ; the 

 head is pale honey yel- 

 low ; the jaws tipped with 

 black ; the rings are very 

 convex, especially the pro- 

 thoracic one ; it is white, 

 with a few fine pale hairs, and is .08 of an inch in length. 



The Magdcdinus olyra Herbst (Fig. 4Go ; a, larva ; &, pupa ; 

 the thorax of the larva is enlarged b}' the pupa growing be- 

 neath ; the pupa from which the drawing was made is not fully 

 developed, since the tip of the fully grown pupa ends in two 

 spines) may be found in all its stages early in Maj^ under the 



bark of the oak. The larva is 

 white, with the head freer from 

 the body than in Pissodes strobi 

 (though it is not so represented 

 in the figure). The body of the 

 beetle is black, punctured, and 

 the thorax has a lateral tubercle 

 on the front edge, while the tarsi 

 are brown with whitish hairs. It 

 is a quarter of an inch long.

 and the snout is cui-ved, rather longer than the thorax, 

 and bent on the chest when at rest. It is dark brown, 

 spotted with white, ochre-yellow and black, and the surface is 

 rough, from Avhich the beetle, as Harris says, looks like a
