Family SCUTELLERIDAE. 

 Subfamily Scutellebinae. 



Homaemus aenifrons Say. Less common than the following. 

 Three specimens from Ames, Hills and Iowa City. 



Homaemus bijugis Uhler. Several specimens from Iowa City, 

 Monticello. AVaukon and Storm Lake. Professor Osborn re- 

 corded it also from Ames and Little Rock. 



Eunjgaster aliernatus Say. Professor Osborn says of this 

 species (Proc. la. Acad. Sei., Vol. I, part II, 1890-91) "not 

 common," but no localities are cited. A single specimen has thus 

 far been collected at Red Oak in July. 



Family PENTATOMIDAE. 

 Subfamily Pextatominae. 



Banasa dimidiata Say. Recorded from Ames by Professor 

 Osborn who says further that it is "not common." One speci- 

 men, November 13, under fallen leaves. 



Dendracoris humeralis Uhler. Two localities only are repre- 

 sented, Solon and Robinson: August. The Robinson specimens 

 were taken on hazel. 



EuscJiistus i&tericus Linn. Iowa City and Algona. Professor 

 Osborn in Proceedings of the Iowa Academy of Science, Volume 

 I, part II, 1890-91, records a single specimen of this species 

 which he says was "doubtless taken in the state." 



Etischistus tristigmus var. pyrrhocerus H-S. This variety of 

 the typical tristigmus was not recorded by Osborn. All the 

 specimens agree in having the humeri produced into long, acute 

 spines and in having the antenna? entirely pale; they also aver- 

 age somewhat smaller than tristigmus. Specimens from Iowa 

 City and Solon only; taken in August and November. The 

 August specimens were taken on wild raspberry and the No- 

 vember specimens from under dried leaves. 



Euschistus variohirius P. B. Abundant. Collected in prac- 

 tically every locality. Apparently hibernates very successfully 

 under leaves, sticks, grass, etc., and is often found in the same 

 localities as Hymenarcys aequalis Say. 



Minnies insertus Say. Osborn says of this species "rare." 

 Our collection of twenty-four specimens does not contain ma- 

 terial from other localities than Iowa City and in no case have
