The family COLYDIID^E (Col-y-di'i-dae) is composed of 
small insects which are usually of an elongate or cylindrical 
form, and are found under bark, in fungi, and in earth. 
Some of the species are known to be carnivorous, feeding 
on the larvae of wood-boring beetles. The tarsi are four- 
jointed ; the tibiae are not fitted for digging, and the first 
four abdominal segments are grown together on the ventral 
side. More than fifty North American species are known. 
The family Ri-IYSSODID/E (Rhys-sod'i-dae) includes only 
four species, two from each side of the continent. They 
are elongate, somewhat flattened beetles, with the head and 
prothorax deeply furrowed with longitudinal grooves. They 
are found under bark. 
Family CUCUJID^: (Cu-cu'ji-dae). 
The Cucujids {Cu*cn-jids). 
The insects of this family are very flat and usually of 
an elongate form; most of the species are brown, but some 
are of a bright red color. As a rule they are found under 
bark and are believed to be carnivorous both in the larval 
and adult states ; but some feed in grain.
