SCUTELLEROIDEA OF IOWA 73 
General form broadly ovate, strongly convex above and below, the sides 
almost parallel to a point opposite apex of scutellum from which point the 
insect narrows gradually posteriorly. General color dark green to olive 
brown. Punctation distinct, close, fairly fine and uniform. Head short, 
flattened above, closely, uniformly punctate, the juga blunt at apex, slightly 
surpassing tylus but not approaching before it; tylus very distinct; extreme 
lateral margins of head black, somewhat sinuate in front of eyes, the latter 
surrounded by a whitish calloused area of varying extent. Rostrum extend- 
ing to posterior coxal margins, the second segment much longer than the 
third, the third and fourth subequal, the fourth with the apex black. An- 
tennae black except basal segment and more or less of basal portion of sec- 
ond segment which are green; second segment much longer than third. 
Pronotum moderately narrowed anteriorly, the sides slightly, arcuated, 
Sharply carinated, the punctuation regular, finer and closer anteriorly, 
gradually becoming coarser posteriorly; carinate margin and a uniform 
line just within pale yellowish to reddish; humeral angles prominent, 
broadly rounded. Scutellum broad at base, the apex not acutely narrowed, 
the tip well rounded; base with three pale calloused points, the apex pale 
yellowish to reddish; punctuation coarser towards base, becoming a little 
finer towards apex. Hemelytra uniformly punctate, the punctures at base 
and along costal margin a little finer than those on disk; costal margin 
varying from pale yellowish to reddish for about half its length; mem- 
brane hyaline, slightly exceeding abdomen, the nervures fuscous, heavy. 
Dorsum of abdomen black, the connexivum varying from pale yellow to 
reddish yellow, darkest on extreme margin and more or less distinctly 
scalloped within. Venter greenish yellow thickly covered with fine darker 
green punctures united by fine impressed lines thus giving an irregular 
finely strigose or aciculate effect; narrow mid-ventral line unsculptured, 
paler. Pleural pieces of thorax strongly, irregularly punctate. Legs greenish 
yellow, the tips of tibiae, the tarsi and the claws fuscous. ee 11.0- 
14.5 mm. Width across pronotum, 6.5-8.5 mm. 
While this species is quite different from and is nee likely to 
be confused with any other Iowa pentatomid, it does resemble 
somewhat, other allied and extralimital forms from which, how- 
ever, further differentiating characters need not be discussed 
here. 
The usual variation in color and size obtains in C. uhlera, 
those individuals having the general coloration very dark green- 
ish or brownish usually having the pale markings a deep red. 
Dark colored individuals are most likely to be met with in the 
autumn towards the close of the season. 
So far as I am able to learn this insect was not reported from 
Iowa by Osborn, its first occurrence in the state being noted by 
the writer in 1915 (1. c.). It is a widely distributed form which
