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. 
A 
CHELYMORPHA Chev. 
C. argus Licht. Throughout the State, common; on “Convolvulus” and 
“Asclepias,” and sometimes attack raspberries (Ch). 
Family BRUCHIDiE. 
These are the pea and bean 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 so as to 
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, 
and several larvae are often found in the 
larger seeds. Fumigating with bisulphide 
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. robinise Sch. Throughout the State IV-VIII, the larvae in seeds of the 
honey locust “Gleditschia,” but local and by no means common.
