INSECTS INFESTING THE RASPBERRY.

Fij?. 200. 



" These bugs puncture the young twigs and fruit and imbibe 

 the sap ; but the injury they occasion in this direction is as 

 nothing compared to the effect which their presence has upon 

 the fruit, as they exhale an offensive oder which renders the 

 fruit upon which they congregate wholly unfit to be eaten ; 

 besides this, their small size renders their detection very diffi- 

 cult, so that a person is likelv to get one or more of them into 

 his mouth, along with the fruit, without being aware of it." — 

 Riley. 



Fig. 200. — Negro Bug, natural size and 

 magnified — colors, black and white. 



The young bugs closely resemble the 

 adults (Fig. 200), but are of a more brown- 

 ish color and are entirely destitute of 

 wings. 



I have a specimen found on the cherry 

 that agrees with the above description, excepting stripes on 

 the wing-case. It is probably a closely allied species, but I 

 have found the genuine negro bug in Southern California, on 

 purslane.
