Occasional Papers of the Museum of Zoology 37 



Saldula orbiculata (Uhler). Rather uncommon. This spe- 

 cies was collected on the shore of the Galien River in the 

 Warren Woods, June 25 to 29, and at New Buffalo, June 30. 



Saldula interstitiaiis (Say). By far the most common and 

 widespread Saldid found in Berrien County. This was the 

 only member of the family that I found on the beach of Lake 

 Michigan : and even in this case the bugs were confined to a 

 narrow strip about the broad pool which Bridgman Creek 

 formed on the lake beach. 



Saldula reperfa (Uhler). Moderately common on the sandy 

 shores of the Galien River in the Warren Woods, June 20 to 

 July 5- 



Micracantliin Jiumilis (Say). This species was also found 

 in fair numbers beside the Galien River, but it was most abun- 

 dant among the grasses and on the damp sand flat about the 

 edges of the Bald Tom Pond, June 20 to July 11. 



NOTONECTIDAE 



Notonecta undulata Say. Abundant at New Buffalo, where 

 it was found in the marsh and also in a large concrete tank 

 at the edge of town. Other specimens were taken at Harbert 

 and in the Galien River at the Warren Woods, but this species 

 was not collected in the dune region. 



Notonecta irrorata Uhler. Partial to the sluggish plant-free 

 streams and pools in shady situations, and found both at the 

 Warren Woods and in the dune region. This is the only Noto- 

 necta that I took from beach drift. 



Notonecta variabilis Fieb. A few specimens were taken 

 from a sluggish stream in one of the glens at the edge of the 

 Warren Woods, and several others were taken from Bald 

 Tom Pond.
