The Guain or Corn AVeevil. 

 (Ccdandra granaria, Linn.) 



The grain or corn weevil is a dark brown or black beetle 

 about three sixteenths of an inch in length. This weevil 

 can be distinguished from the grain beetle, which also in- 

 fests corn, by its stouter body and by the presence of a long 

 snout, which is wanting in the grain beetle. Figure 9 shows 

 the grain or corn weevil enlarged at e and with a natural size 

 figure just above. The snout can be readily seen by glanc- 

 ing at the figure. The female beetle deposits her eggs sin- 

 gly upon the corn, and also upon wheat in some cases. In 

 a few days the eggs hatch, and the small larv?e enter the 

 corn, and feed upon and burrow through it. The full grown 

 larvffi transform to the pupa stage within the kernel. The 

 adult beetles emerge by cutting a hole through the skin of 

 the kernel of corn or wheat as the case may be. An ear of 

 corn infested with these weevils will be full of holes, show- 

 ing where the adult beetles have emerged.
