termites and ants. The one species in the Lepidoptera consisted of 

 the noctuid Scolccocampa liburna Geyer whose larva lives in decayed 

 wood. In the Hymenoptera, Halictns piira (Say) and a species of 

 CJiloralictus were taken from a dead birch stump where they were 

 nesting. 



In one of the drier upper portions of the woods were comparatively 

 small stones and the 17 species, mostly of Coleoptera, were collected 

 under them. 



In Dead Trees in the Woods. 



Dead trees, particularly standing or recently fallen ones which had 

 not started to decay, yielded IsorJiipis rnficornis (Say) and Ptilinus 

 ruficorms Say both of which were fairly numerous in dead red 

 maple where they develop. The dead hickories were infested by 

 Cryptorhynchus ohtentns (Hbst.), the ash by Leperisinus acideatiis 

 (Say), and from dead oaks Stcnoscclis hrevis (Boh.) was taken. 



The 170 species listed above were taken by being captured in 

 flight or by sweeping the vegetation on the ground, the shrubs and 

 low tree branches. The Diptera supplied the largest number of 

 species, namely 24 per cent, of the toal number, and was followed 

 by the Lepidoptera with 22 per cent., the Coleoptera with 18 per 

 cent, and the Hymenoptera also with 18 per cent. The numerous 

 families represented in these orders are shown above. Several species 

 of Microlepidoptera as yet unidentified were collected and many 

 others observed.
