Body elongate-oval, not so distinctly narrowed behind as in P. cinctipes. 
Color above averaging lighter and the punctuation a little finer than in 
that species; color beneath black. Head black, deeply punctate, the tylus 
slightly shorter than the laterai lobes and less strongly elevated than in P. 
einctipes; juga almost contiguous. Eyes stylated, slender. Antennae 
shorter than in P. cinctipes the second and third segments more strongly 
differentiated than in that species. Rostrum with basal segment piceous, 
second segment pale yellow, two apical segments fuscous, the incisures pale 
yellow. Pronotum with anterior furrow further removed from anterior border 
than in P. cinctipes, this border raised more above the base of the head and 
the median transverse furrow is more uniform than in that species; humeral 
tooth short, acute, produced downwards and backwards, the anterior mar- 
gin nearly straight; anterior angles with a small pointed tubercle. Scutel- 
lum deeply, quite uniformly punctured, the areas between the punctures 
testaceous; a yellowish calloused spot at the outer anterior basal angles. A 
mere or less distinct median, calloused, impunctate longitudinal line con- 
vinuous with a similar line on the pronstum is continued backwards to near 
the apex of the seutellum. Venter black, deeply, almost uniformly punc- 
tured to apex; incisures with pale points; basal part of genital segment of 
male long, punctured; the apical sinus broad and shallow, the outer apical 
angles rounded and not prominent. In the female the inner and median 
plates almost attain the line of the outer plates. Femora and tibiae black- 
ish with one or two pale bands; first and second tarsal segments pale yellow, 
third and the claws brownish or piceous. Length, 5.0-5.5 mm. Width 
acress pronotum, 3.0-3.5 mm. 
The small size, the distinctly explanate juga, the less elevated 
apex of the tylus and the short acute humeral tooth will serve 
in differentiating this species. In addition, all my specimens 
show a more or less definite median, calloused longitudinal line 
on the seutellum which extends nearly to its apex. 
This species was first recorded in the state from the Lake 
Okoboji region by the writer in 1917 (l. c.). Indeed, it proved 
to be more common in that locality than the preceding species 
and was found in similar situations. Specimens are also at 
hand from Estherville and Solon. 
The ostiolar area of our two species of Podops is very similar 
but differs in appearance from that of any other Iowa repre- 
sentatives of the Scutellercidea. The orifice is well outside and
