SCUTELLEROIDEA OF IOWA 127 
Podisus modestus (Dallas) (Puatse VII, Fiaure 6) 
1851. Arma modesta Dallas, List Hem., I, 101. 
1867. Rhaphigaster aggressor Walker, Cat. Het., II, 359. 
1880. Podisus modestus Distant, B. C. A., Rhynch. Het., I, 38, Pl. 4, fig. 4. 
1897. Podisus modestus Kirkland, Rept. Mass. Sta. Bd. Agr., XLV, 419. 
1904. Podisus modestus Van Duzee, Trans. Am. Ent. Soc., XXX, 71. 
1907. Apateticus modestus Schouteden, Gen. Ins., fase. 52, 72. 
Form narrow, depressed. Upper surface pale yellow, more or _ less 
closely punctured with red. Rostrum stout, reaching to or between posterior 
coxae. Second antennal segment slender, comparatively short, little more 
than three times as long as first. Coriaceous portion of hemelytra tinged 
with reddish at junction with membrane, the latter bronze brown with a 
dusky vitta. Venter pale yellowish, shining, punctured with red; usually 
with a row of four small dots on the median line and another series on 
either side of the third, fourth, fifth and sixth visible ventral segments. 
Ventral spine very short. Legs paie yellow to orange. Length, 7.0—-10.0 
mm. Width across pronotum, 4.5-5.5 mm. 
This is the smallest Lowa species of Podisus and is very similar 
to the light phase of P. serveventris. It may be separated from 
that species by the paler color, the shorter second segment of the 
antennae, the more depressed form, the paler tergum, the shorter 
yentral spine and the smaller size. 
Professor Osborn recorded a single specimen of this species 
from Ames. My collection contains numerous specimens from 
Robinson only ; they were collected in August on hazel.

1904. Podisus placidus Van Duzee, Trans. Am. Ent. Soc., XXX, 71. 
1907. Apateticus placidus Schouteden, Gen. Ins., fase. 52, 72. 
Body elongate ovate, pale yellow, thickly punctured with red giving a 
mottled, reddish brown appearance. Head shorter than in the other spe- 
cies of the genus, the margins fuscous or black; juga not longer than, 
usually a little shorter than tylus. Rostrum pale yellow, moderately heavy, 
apical segment fuscous. Antennae reddish, second segment three times as 
long as first; a small black spot in front of each eye. Pronotum sparsely, 
irregularly punctate before the middle and more or less transversely 
wrinkled; more finely and densely punctate on posterior half; antero- 
lateral margins pale yellow, weakly denticulate anteriorly; humeri rounded, 
projecting only slightly. A black dot at tip of ostiolar canal. Scutellum 
much more finely punctate towards the apex; tip pale; a pale, more or less 
distinct calloused line extends from middle of anterior margin of pronotum
