ordinary form as follows: general color brownish green to yel- 
lowish brown, with faint fuscous vermiculations on thorax, 
corium and scutellum. On latter, fuscous markings are aggre- 
gated, and bound a sharply defined pale median vitta from apex 
to near base. Lateral margins of pronotum in pronounced forms 
nearly black. Corium with numerous small, distinct, irregular 
pale areas. Membrane with numerous distinct black dashes along 
veins. Connexivum more distinctly banded. Lower surface par- 
taking of the general ground color, plentifully sprinkled with 
fuscous to black dots. Spiracular orifices and ends of abdominal 
incisures black.

BLAcK PoINnts AT EDGE OF ABDOMINAL INCISURES OF 
Euschistus. 
This character used for the third division in Van Duzee’s key 
to the species of Euschistus,* is not, I am convinced, extraordi- 
narily reliable in the differentiation of Pentatomide. Specimens, 
which by their identity in every other respect certainly are 
Euschistus variolarius Pal. Beauv. have distinct incisural spots, 
although absence of such spots ordinarily is one of the best marks 
of that species. Specimens at hand with incisural spots are 
from Riverhead, N. Y., West Cornwall, Conn., Westport, Conn., 
and Mendham, N. J.
