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

 craubeny. "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 tlien deposited in tlie hole made, wlicn the beetle 

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

 which drops to the ground and there decaj's ; the egg hatching 

 and the grub going through its transformations Avithin." The 



larva is long and rather 

 ^/'~~^. slender, cylindrical, the 

 body being of uniform 

 thickness and curved ; tlie 

 head is pale honey j-el- 

 low ; the jaws tipped with 

 black ; the rings are ver}--

 thoracic one ; it is white, 

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



The Magdalinus olyra Herbst (Fig. 4G5 ; a, larva; b, pupa; 

 the thorax of tlie 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 earl}' in May under the 



baric of the oak. The larva is 

 wliite, 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 latei*al tubercle 

 on the front edge, Avhile the tarsi 

 are brown with whitish hairs. It 

 is a quarter of an inch long. 

 Conotrachelus nenuphar Herbst, 

 the Plnm-\veevil (Fig. 4G6 ; a, larva; &, pupa; c, beetle; d, 

 plum stung by the Aveevil) is a short, stout, thick Avoevil, 

 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-yellow and lilack, and the surface is 

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