SCUTELLEROIDEA—DOUGLAS LAKE REGION 59 
these insects do not ‘‘let go’’ suddenly when the tree upon 
which they are resting is beaten or disturben, but they seem to 
cling to it all the more tightly under such conditions. As a 
' result I often found that, after beating the foliage of a tree 
thoroughly, I was able to obtain another specimen or two by 
shaking the branches very hard. 
Toward the middle of August a few specimens of this species 
were taken from round-leaved dogwood (Cornus circinata) 
growing along the beach near Grapevine Point. The only other 
plants upon which I have taken the species in the region are 
blueberry (Vaccinium) and service berry (Amelanchier cana- 
densis ). 
During the summer of 1920 high winds seemed to be more 
prevalent than during the previous season and a good many 
insects were found in beach drift. There is no doubt that dur- 
ing these high winds flying insects of various kinds are caught 
by them and blown out on the lake, where they fall to the 
surface of the water, to be later washed ashore by the waves. 
In the first week of July, 1920, more pentatomids were found 
in beach drift near the Biological Station than during the en- 
tire season of 1919, and among this lot was a number of B. 
dimidiata. 
This is the only greenish pentatomid of the region in which 
the basal half of the pronotum and more or less of the hemelytra 
are colored reddish or olive brown. Length, 8.0—11.0 mm. 
Considerable variation in coloration is exhibited by the speci- 
mens in my collection. Recently molted adults are almost a 
uniform pale yellowish, the basal pronotal band being not yet 
well marked. In some fully matured examples the anterior 
half of the pronotum and the extreme tip of the scutellum are 
reddish brown. 
Subfamily Acanthosomatine 
Meadorus lateralis (Say) 
Of this northern representative of our pentatomid fauna I 
have in my collection four specimens, two males and two females 
from the Douglas Lake region. Al! were taken between July 
10 and 24, 1919. During the season of 1920 I saw but one
