of 1919. less common in 1920. A long series of individuals 

 was taken in various fields about the Warren Woods, June 20 

 to September 3, especially from the goldenrods and ragweeds ; 

 and a few specimens were taken from similar situations in 

 the Sawyer Dune area. 



Perigenes constrictus (Say). One was found on the sand 

 in a road near Harbert, June 22 ; two were taken from rag- 

 weed near the Warren Woods, September 3 ; and one was 

 collected at Klute's Lake, September 4 (Hubbell). 



Orth<€a basalis (Dall.). One only, from the marsh near the 

 Warren Woods, which has been mentioned in connection with 

 Cymus discors. This specimen was taken on June 29. 



Sphragisticus nebulosus (Fallen). Rather common near the 

 sand dunes, and found in the same situations as Geocoris bul- 

 latns. Two specimens were also taken on ragweed at Bridg- 

 man, July 12. 



Bmblethis z'icarius llorv. Several specimens were secured 

 in a sandy field behind the dunes, July 12 to 20. 



PlESMIDAE 



Piesma cinerea (Say). One, beaten from willow beside a 

 small creek in the dunes near Bridgman, July 9. 



TiNGIDAE 



Gargaphia tilicc (Walsh). Abundant throughout the sum- 

 mer on the basswood, Tilia americana, both in the Warren 

 Woods and on the Sawyer Dunes. 



Leptoypha mittica (Say). Rather common on Fraxinus 

 americana on the dunes, both adults and nymphs being found 

 in fair numbers late in July. This species appeared to favor 

 the seedlings of the ash, and, as far as I could observe, occurred 

 only on the upper side of the leaves, near the mid-rib.
