SCUTELLEROIDEA OF IOWA 19 
finely, irregularly with fuscous; median line pale clay yellow and in the 
female expanded for about the posterior one-half, the margins not sharply 
defined towards tip; a series of blackish punctures either side of median 
line at base forms two short lines whose apices curve toward each other; 
a large irregular brownish or black area made up of closely set punctures 
either side of median line a little in front of middle. Hemelytra with a 
large angulate fuscous or black area interior to apex of coriaceous portion. 
Venter dull yellow, irregularly and deeply punctured with black; stridu- 
lating spots very distinct; connexivum marked with black points at the 
incisures. Legs conspicuously covered with short yellowish or whitish 
hairs heavier and more closely implanted on the tibiae; coxae pale yellow, 
the femora and tibiae deeply and in some places confluently punctured 
with fuscous; apical tarsal segment darker than the others; claws tipped 
with black. Length, 6.0-7.5 mm. Width across pronotum 4.0-4.75 mm. 
This species is subject to about the same degree of variation as 
the other representatives of the genus. In the specimens before 
me the posterior half of the lateral margin of each segment is 
not distinctly darker than the remainder of the segment. The 
markings of the prothorax and scutellum have been used as a 
pasis for division into varieties. 
Osborn recorded this southern species from Iowa in 1890 but, 
as Van Duzee suggests, ‘‘It is just possible that this reference is 
an error either of determination or locality’’ (J. c.). Specimens 
have not been taken in Iowa by us and the recorded range in the 
United States is far to the southwest. 
Subfamily ODONTOTARSINAE (Stal) 
This subfamily is but poorly represented in North America, a 
total of but five genera and ten forms being recorded. Over 75 
percent of the described forms are from the Palaearctic region. 
A single species is recorded for Iowa. 
Body about equally convex above and below, not pubescent. Second 
segment of antennae straight or slightly curved at base. Pronotum and 
scutellum continuous at base; basal angles of pronotum obtusely rounded; 
antero-lateral border of pronotum generally little or not at all arcuated. 
_Meso- and metasternal groove plain, sometimes limited at each side by 
a crest or tubercle but never by a carina. Orifices distinct or not. Ven- 
tral incisures more or less gradually curved on disk. No striate stridu- 
lating spot.
