[May 1896. 



Say and Silpha noveboracensis Forst., 

 have beeti taken on or before April ist. 

 They doubtless hibernate. 



SCYDMAENIDAE. 



84, Scydniaenus sp.? One, Jan. 

 6, beneath log in upland clearing. 



PSELAPHIDAE. 



85, CeopJiyllus monilis Lee. One, 

 from a large cone-shaped ant's nest, 

 Feb. 28. 



86, Tmesipkoriis costalisl^sc. Our 

 most common species of the family. 

 On numerous occasions in winter from 

 beneath logs, usually oak, in sandy 

 upland woods. Gregarious. 



87, Ctenistes picc7is\-.&z. Dec. 23. 

 Five were found piled up together, on 

 the side of an overturned log, on sandy 

 margin of old canal. 



SS, Batrisus sp.? Dec. 10. One. 

 Beneath log in upland thicket. 



Staphylinidae. 



S9, Falagria veniistula Er. Jan. 7. 



90, Aleochara hii>iaculata Grav. 

 Jan. I. 



91, Aleochara sp.? Dec. 23. 



One or two of each of the above were 

 taken on the dates mentioned from be- 

 neath logs. A. bimaculata is common 

 in fungi in summer ; the others are rare 

 at all seasons. 



92, ^iiediiis fulgidus Fab. Dec. 25. 

 Beneath the bark of red oak {^uerciis 

 rubra L.) logs. 



93, Staphylinus maculosus Grav. 

 Dec. iS. 



94, .S". tomentosus Grav. Feb. 6. 



95, vS". cinnamopterus Grav. 



Of eight species of this genus known 

 to occur in the county the above three 

 were the only ones taken in wintei'. 

 S. cinnamopterus is the most common 

 of all, and hibernates beneath beech and 

 oak logs ; the others, beneath logs and 

 chunks near decaying animal matter. 

 In summer all are found in fungi. 

 5". vnlpinus Nordm. has been taken 

 on April 1st, and probably hibernates. 



96, PhilontJiiis brioDiens Grav. 

 Dec. S. 



97, P. baltimorensis Grav. Dec. 10. 



98, Xantholinus cephahis Say. 

 Dec. 25. 



99, A', etnmesus Grav. Jan. 6. 



Of the above, P. brimneus is com- 

 mon, the others scarce. All hibernate 

 beneath logs and rubbish in fence 

 corners which are filled with dead 

 leaves. The only specimen of A', ce- 

 phalus taken was rolled up like a rib- 

 bon and did not move until after it had 

 been in the cyanide bottle for some sec- 

 onds. 



100, Stenus co/o?i?is Er. 

 loi, .$■. annularis Er. 



But the two members of this large 

 genus have been recognized in the 

 county. 6'. colonus is very common in 

 winter beneath and between the radical 

 leaves of mullein ; 6". annularis much 

 less common beneath logs and rubbish.
