prominent, sometimes spinous, scutellum broad, narrowed toward 

 apex. 



The species are confined almost entirely to a plant diet, but they 

 are of little economic importance as they frequent plants of little 

 value as a general rule. Some of the species occur in great 

 abundance in autumn on goldenrod. They have a general resem- 

 blance to the predaceous and highly beneficial species of Podisus, 

 which may be distinguished by the spine at base of abdomen and 

 the enlarged first segment of the rostrum. 



Key to Species. 



1. Pronotum without a raised impunctate line connecting the lateral 



angles 2 



Pronotum with such a line ictericus 



2. Juga not distinctly longer than tylus 3. 



Juga distinctly longer than tylus, but not meeting in front 



euschistoides 



3. Lateral) angles of ventral abdominal segments with a black dot . . 4 

 Lateral angles usually concolorous; genital plate of male with a 



dark spot variolarius 



4. Abdomen usually with a median ventral row of black spots ; length 



usually more than 10 mm tristigmus 



Abdomen without ventral spots ; length less than 10 mm politus 



E. euschistoides (Vollenhoven). (fissilis Uhler.) (PI. xviii, 14.)

In this and the other species of the genus the color is brown, 

 varying in each from light to dark, and sometimes tinged with red ; 

 paler on the ventral surface ; punctation dense and blackened more 

 or less ; membrane dotted with brown. 



Juga acute, much longer than the tylus, forming a deep sinus 

 at apex of head. Lateral angles of pronotum prominent, obtuse. 

 Connexivum covered by hemiel)^ra. Length 12-15 mm. 



Taken abundantly in the fall by sweeping goldenrod, clover, etc., 

 and known to feed on many other plants. This and other species 

 of the genus hibernate as adults.
