SCUTELLEROIDEA OF IOWA 47 
with white pronotal and costal margins and the abbreviated 
white lines on the outer sides of the tibiae. 
Sehirus cinctus as a species is widely distributed in the United 
States, Canada and Mexico, and in Iowa is one of the most wide- 
ly distributed members of the subfamily although nowhere can it 
be said to be more than locally common. Specimens are at hand 
from Forest City, Grinnell, Iowa City and Lake Okoboji. 
As with many other cydnids, this form is usually found in 
low sandy places near water. A specimen from Grinnell was 
swept from a raspberry bush. At Lake Okoboji two specimens 
were swept from the blue grass and timothy growing on a low 
cleared space near the woods. The Forest City specimens were 
swept from low weeds growing on the banks of a freshly con- 
structed drainage ditch. One Iowa City specimen was taken 
from wild cherry. 
This species hibernates successfully in Iowa for at Iowa City 
on March 21, 1913, while the frost was still in the ground, living 
specimens were collected from under sticks and boards in a 
meadow which had been used as a pasture during the previous 
summer. On April 16, 1913, a single specimen was taken at 
Iowa City from under a small rock at the edge of the Iowa 
river. 
Again at Iowa City on March 25, 1916 several specimens were 
found under the leaves and in the grass along the sides of a 
large piece of sawed timber lying in a sandy pasture near the 
river. Other specimens were found buried in the soil to a depth 
of an inch and the soil in turn was covered with dead leaves. 
Remains of dead specimens were also found which showed that 
at least a goodly number of the bugs that had chosen this shel- 
ter had not been able to survive the rigors of an Iowa winter. 
On April 1, 1916, near the same locality where the above speci- 
mens were secured, a single live individual was taken from 
under the loose bark of a fallen cottonwood tree. 
Family PENTATOMIDAE (Leach) 
This is the largest and most cosmopolitan family of the Seu- 
telleroidea and contains the greater share of our well known 
forms. In general, the Oriental, Ethiopian and Tropical regions
