detected this little weevil laying its eggs in the buds of the 

 cranberry. "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 

 body 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 Magdalinus olyra Herbst (Fig. 465 ; a, larva ; fr, pupa ; 

 the thorax of the larva is enlarged by 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 May 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

Conotrachelus nenuphar Herbst,

 and the snout is curved, rather longer than the thorax, 

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

 spotted with white, ochre^ellow and black, and the surface is 

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