ApatTeticus [Popisus] MACULIVENTRIS Say 
Pentatoma maculiventris Say, Descrip. n. sp. N. Am. Ins. found in La. by 
Joseph Barabino. Mar. 1831. Reprint, Psyche, Vol. 8, 1999, p. 307. 
Ranges across the United States and Canada, commoner east of the 
Rockies. Found in all sections of Illinois from April 2 to November 22; 
nymphs, from May 28 to October 23; nymphs and imagines both most 
numerous in June and July and the first half of August. It is the most 
useful of our predaceous Hemiptera, and is frequently seen feeding on 
the larvae of the Colorado potato-beetle. We have also found it feeding 
on the 12-spotted cucumber-beetle (Diabrotica 12-punctata) and on the 
larvae of Canarsia hammondi, Hyphantria textor, and Datana ministra. 
The nymph, however, according to Olsen, is principally vegetarian, feed- 
ing on apple, etc. He gives as the food plant, Onagra biennis. 
A. modestus and serieventris are quite close to maculiventris and 
recognizable more by a combination of characters than by any one char- 
acter. A. serieventris has the shortest pronotal hind angles, and a vague 
dark pattern formed by unevenly aggregated dark punctures on a whitish 
or grayish ground-color. The legs and venter have the black markings 
most strongly developed. A. modestus has the least black on legs and 
venter ; the pronotal side angles are never spinose as in maculiventris, but . 
only acute, the two sides approaching at an angle of about 60° (2/3 of a 
right angle) instead of at approximately a right angle as in serieventris. 
The angles in maculiventris although usually spinose are often no darker 
than in modestus, but the distinctive feature of the angle in modestus 
seems to be that the anterior side of the angle is decidedly arcuate, while 
in maculiventris both sides are very nearly straight, or the anterior a little 
concave. Modestus averages a little smaller than maculiventris, but 
serieventris is about the same size. 
Apateticus [Popisus] SERIEVENTRIS Uhl. 
Podisus serieventris Uhler, Proc. Boston Soc. Nat. Hist., Vol. 14, p. 94. 1871. 
I have little doubt that this is the true serieventris as described by 
Uhler. It is not at all common. Van Duzee reports it from Vancouver, 
Montana, and New Hampshire. We have it from the Lake Superior 
region, Vancouver, Wyoming, and Minnesota (Bol.) ; also from Michi- 
gan, and two from northern Ilinois—one from the Lake Michigan shore 
near the Wisconsin line; Long Island; May—September. It feeds on 
larvae of Callosamia promethea, Clisiocampa americana and disstria, 
Hyphantria cunea, dead imagines of Limenitis ursula and Pyrophila 
pyramidoides, also Apateticus cynicus and Menecles insertus, and all 
stages of Porthetria dispar (Olsen).
