ATTACKING THE FRUIT. 317 



they measure about half an inch across. The body is green 

 above and white beneath. 



As the larva of this insect is not usually observed until 

 the fruit is ripe, no poisonous applications to destroy it could 

 be used, and resort must be had, if anything is done, to hand- 

 picking. One species of parasitic insect is known to prey on 

 it. 



No. 185. — The Flea-like Negro-bug. 

 Corimelcena pulicaria Germ. 



This disgusting little pest is not at all uncommon on ripe 

 raspberries. Its presence may be discovered by the fruit 

 having a nauseous buggy odor, but the insect is so small that 

 it is often taken into the mouth un- 

 noticed until the disgusting flavor reveals 

 its presence. In Fig. 331 we have a 

 magnified outline of this insect, the smaller 

 sketch at the side showing its natural size. 

 It is of a black color, with a whitish stripe 

 along each side, and is furnished with a 

 pointed beak or sucker, with which it punctures the fruit and 

 extracts its juices. This troublesome visitor is also found on 

 the blackberry, and occasionally on the strawberry.
