STATE BOARD OF AGRICULTURE. 



O. guttata Oliv. Throughout the State iu May and June ; more common 



southwardy where it also occurs on sweet potatoes, though not in itself 



destructive. 

 C purpurata Boh. Westville, I, 28, in -hibernation ( W). 

 C. clavata Fabr. Occurs throughout the State, though usually not common : 



sometimes it becomes locally abundant on Solanacea and may cause 



injury to potatoes. 



CHELYMORPHA Chev. 



C. argus L/icht. Common throughout the State : found on Convolvulus, 

 Asclepias and sometimes attacks raspberry (Ch). 



Family BRUCHIDJE. 



These are the pea and beau weevils, the larvae of which live in the seeds of 

 leguminous and other plants The beetles are short and chunky, the wing 

 covers cut off square behind, the abdomen obese, head small, posterior legs long, 



the thighs swollen as if for jumping. In 

 color they are usually gray, mottled with 

 black and white, the markings formed of 

 scales and hair covering the surface, so that 

 when these are rubbed off the beetles are 

 mostly uniform black. 



The injury is chiefly done to the stored 

 product, peas, beans and lentils being rarely 

 free, and several larvse being usually found 

 in the larger seeds. Fumigating with bi- 

 sulphide of carbon, as has been elsewhere 

 described, will kill these insects without 

 injuring the germinating power of the seeds, provided they are not exposed to 

 the fumes more than twenty-four hours.
