 about the Warren Woods, July 4 to September 3. 



Trichopepla semivittata (Say). Two adults were taken,, 

 from the same situation as the last species, June 21, and 

 nymphs were fairly common, June 30 to July 5. 



Chlorochroa uhleri Stal. A few adults and numerous- 

 nymphs were taken during- July, on Euphorbia corollata on

Mormidea kigens (Fabr.). Moderately common through- 

 out the summer, especially in grasses in shady localities, 

 though specimens were also taken from raspberry, from Sau- 

 rurus beds, and from the sedge zones in the marshes. Speci- 

 mens were secured in all of my collecting regions. 



Eiischistus euschistoidcs (Voll.). A moderately commoix 

 Pentatomid in the grassy localities about the Warren Woods, 

 especially in the hay fields and by the roadsides, where speci- 

 mens were taken throughout the summer. This species was 

 also secured at New Buffalo, at Bridgman, and, more rarely,, 

 in clearings on the dunes ; it was fairly common in the beach 

 drift. 



Eu-scliistns variolarius (P. B.). The most abundant Penta- 

 tomid in southern Michigan, and found everywhere in Berrien 

 County, though less common on the dunes than in the other 

 collecting localities. It occurred chiefly in the hayfields and

 half of July it was the most abundant hemipteron found in. 

 the beach drift.
