of which are known as "peddlers." They attack the plants soon 

 after they are set out and injure them severely before they can 

 get a start, especially in dry weather. Plants should be dipped when 

 set in arsenate of lead, 1 pound in 10 gallons of water; but do not 

 dip the roots. 



COPTOCYCLA Chev. 



C. bicolor Fab. (aurichalcea Fab.) Throughout the State on "Convol- 

 vulus" V, VI; common and destructive on sweet potatoes in South 

 Jersey. A gold-bug like the preceding and amenable to the same 

 remedies. 



C. signifer Hbst. (guttata Oliv.) Throughout the State V, VI, more 

 common southwardly, where it also attacks sweet potatoes. 



C. purpurata Boh. Cramer Hill V, Woodbury VI, VIII, 29 (GG) ; West- 



ville I, 28, in hibernating quarters (W). 

 C. clavata Fab. Throughout the State, usually not common; sometimes 



locally abundant on potatoes, etc., and causes injury. 



CHELYMORPHA Chev. 



C. argus Licht. Throughout the State, common; on "Convolvulus" and 

 "Asclepias," and sometimes attack raspberries (Ch). 



Family BRUCHID^. 



These are the pea and bean weevils, the larvas of which live in the seeds 

 of leguminous and other plants. The beetles are short and chunky, the 

 wing covers cut off square behind so as to expose the tip of the obese 

 abdomen; head small, posterior legs long, 

 the thighs swollen, but not fitted for jump- 

 ing. 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 done chiefly to the stored 

 product, peas, beans, lentils, and the like, Fig- J 47- The "bean weevil," 

 and several larvae are often found in the much enlarged: b, an in- 

 larger seeds. Fumigating with bisulphide fested bean, 

 of carbon kills these insects without injuring the germinating quality of 

 the seeds, provided they are not exposed to the fumes more than twenty- 

 four hours. 



SPERMOPHAGUS Sch. 



S. robimae Sch. Throughout the State IV-VIII, the larvae in seeds of the 

 honey locust "Gleditschia," but local and by no means common.
