SCUTELLEROIDEA OF IOWA 113 
States. The principal characters of the genus follow: 
General form broadly oval. Head narrow, depressed, the lateral lobes 
flattened, longer than the tylus and meeting in front of it but the anterior 
margins are separated by a narrow cleft; basal segment of antennae not 
reaching apex of head; bucculae very narrow, a little shorter than head, 
sinuate at base. Pronotum very short and wide, gradually sloping towards 
anterior margins, the lateral angles wide, lobate. Scutellum broad, short, 
apex bluntly rounded. Posterior margin of corium obliquely rounded. 
Ostiolar opening continued into a long, gradually disappearing wrinkle.

General form broadly ovate, the lateral angles prominent. Color pale 
yellowish, tinged with orange, finely, rather remotely punctate with red 
and black. Head long, narrow, the lateral lobes lamellate, broadly round- 
ed, longer than juga, sometimes meeting in front of it, sometimes with a 
deep fissure between their apices; punctuation of head confluent at base, 
more remote on juga which are narrowly margined with black; a short 
impunctate line on middle of tylus and an oval impunctate area just with- 
in each eye; tylus acutely tapering at tip; a short black line on under 
side of head in front of each eye. Antennae rufous, the basal segment 
stout, the remaining segments slender, the second segment shortest; tooth 
on antennal tubercle stout, black above. Rostrum pale yellowish, piceous 
at tip, reaching between midcoxae. Pronotum very short and wide, pale 
yellowish, punctured with red and black, the punctures more or less con- 
fluent near lateral margins; a black spot anteriorly each side of median 
line; humeri triangularly produced, tinged with rufous; antero-lateral 
margins pale, rather deeply sinuated, a small tooth at antero-lateral an- 
gles, the edge roughened a little behind it. Scutellum pale yellow, sharply 
punctate with brown, the punctures arranged in more or less uneven and 
transverse rows; apex wide, broadly rounded; a black spot on either side 
at narrowest point. Hemelytra wide, but not covering the connexivum; 
coarsely, remotely punctate with a few impunctate areas, the base and 
inner margin tinged with red; embolium rufous, irregularly punctate; 
membrane hyaline, somewhat bronzed. Connexivum orange with a black 
point at the outer posterior angle of each segment. Venter pale yellow- 
ish, remotely punctate with reddish. Sternal plates of thorax much more 
coarsely punctate. Legs pale yellowish, the tarsi and tibiae tinged with 
reddish. Ostiolar opening continued laterally in a gradually disappearing 
wrinkle. Posterior margin of anal segment of female with a short black 
line on either side. The posterior edge of the genital segment of the male 
is very deeply incised at the middle. Length, 6.5-8.5 mm. Width across 
pronotum, 4.5-5.25 mm.
