Occasional Papers of the Museum of Zoology 25 



Acholla multispinosa ( De Geer). Several specimens were 

 beaten from a hickory at the edge of the Warren Woods, 

 August 31. 



Sinea diadema (Fabr.). The most abundant Reduviid in 

 Michigan, found in all grassy localities from late July till 

 October. 



Nabidae 



Nabis suhcoleoptratus (Kirby). Plentiful in the grass in 

 moist situations about the Warren Woods, and in similar places 

 in the dune region. This species was most abundant during 

 the early summer ; no specimens were taken after July 27. 



Nahis sordidus Reut. Rather uncommon ; taken sparingly 

 from undergrowth in the woods and from woodland grasses, 

 both in the Warren Woods and in the dune forests. 



Nobis annulatus Reut. Two individuals, beaten from alder 

 in a swamp at New Buffalo, September 3. 



Nabis propinqims Reut. Moderately common on bulrushes 

 and sedges in the marshes at New Buffalo and at Stevensville. 



Nabis ferns (Linn.). One of the most abundant Hemiptera 

 of the grasslands in Berrien County. The specimens taken 

 late in June appear to average somewhat smaller than those 

 taken later in the summer. This species was very active at 

 night : several specimens came to light, and large numbers 

 could be taken by sweeping the grasses after dark : many of 

 these were feeding when taken. 



Nabis roseipennis Reut. Fairly common. Specimens were 

 secured at Bridgman and in the Warren Woods area, July 5 

 to September i. 



Nabis rufusculus Reut. A few were beaten from bushes at 

 the edge of the Warren Woods, September i.
