B. unicolor Say. Throughout the State, adult in flowers; larva a whit¬ 
ish maggot in fruits, chiefly of raspberry; the one exception in our 
fauna to the feeding habits detailed in the opening paragraph.

D. caninus Germ. Throughout the State V, VII, IX, under dead animals, 
sometimes, rather common; not usually in houses. 
D. lardarius Linn. The “larder beetle,” common throughout the State, 
often on stored provisions. Kill the beetles and larvae whenever 
seen, keep provisions in tight or screened receptacles, and, where 
the insects are abundant, trap them on easily accessible scraps. 
D. vulpinus Fab. Throughout the State under old bones and dried car¬ 
casses; also in skins and leather, hence known to manufacturers as 
the “leather beetle”; gasoline and carbon disulphide may be used. 
D. frischii Kug. Riverton IV, Burlington Co. VI (GG); seashore (Li); 
TFTgantine Beach IX (Hn); locally not rare; but not a troublesome 
form.

beetle.” Also said to attack cereals and other seeds. Gasoline and 
carbon disulphide are used for their destruction, and naphthaline 
may be used as a repellant.
