SCUTELLEROIDEA OF IOWA 81 
coxae. Pronotum more finely, irregularly and sparsely punctate on ant- 
erior haif, the antero-lateral edges concavely arcuated and denticulate; 
humeri prominent, rounded, not angulate. Scutellum long, irregularly 
punetate with black, the punctures a little finer and more sparsely ar- 
ranged towards tip; usually a more or less distinct, impunctate, calloused 
area on median line at base; apex pale. Hemelytra with irregularly ar- 
ranged fuscous punctures, the area between the punctures somewhat 
coarsely aciculate; punctuation of embolium more regular and a little 
closer and finer than that on corium, thus differing in this respect from £. 
servus ; membrane dusky, dotted with fuscous, paler towards tip. Tergum 
blackish, the margins regularly pale but not showing beyond the hemelytra. 
Venter pale yellowish, finely punctate and very finely aciculate; without 
black points at the outer posterior edges of the incisures. Ventral thoracic 
plates coarsely, irregularly punctate. Sometimes the whole inferior sur- 
face is sprinkled with red specks which become larger on the thoracic 
plates. Legs reddish yellow with large black points, the tibial spines 
rather numerous toward apex; tarsi pale yellowish, the apices of the seg- 
ments and tips of the claws fuscous. Length, 12.0-14.0 mm. Width across 
humeri, 7.0—-8.5 mm. 
The nearest ally of this form in our fauna is Z. servus but 
the following salient differences are to be noted: £. euschistoides 
has the abdomen narrower and entirely covered by the heme- 
lytra, the apex of the head deeply incised, a finer, less dense 
punctuation on the embolium, a comparatively shorter second 
antennal segment and no black points at the incisures. Other 
differentials are indicated in the description. 
With this species as with other members of the genus, consid- 
erable variety in color occurs, the variation extending all the 
way from pale yellow to dark reddish brown. As cold weather 
comes on in the fall more individuals of this darker color are to 
be observed. At that season specimens are often to be found 
under dried leaves. 
This member of the genus has been recorded as ‘“common’’ by 
Osborn and at the present time it retains this status in the state. 
Numerous examples are at hand from Amana, Estherville, Fair- 
field, Hamburg, Indianola, lowa City, Lake Okoboji, McGregor, 
Monticello, Robinson and Sioux City. Adults have been taken 
from April 24 to November 6 and are most abundant in June 
and September. All the nymphs of this species have been taken 
in July. Two broods in a season are indicated from the data 
at hand.
