The Coleoptcra Found in a Bam. 

 By H. W. Wenzel, Philadelphia. 



The following list is the result of an experiment made during 

 the month of May, 1900, with the object of determining the 

 Coleopterous fauna of an old barn. The building from which 

 the material was collected stands in the lower section of our 

 city, is an old wooden structure parth' wrecked by age and no 

 longer in use for storing products. 



The usual species infesting stored grain were not found, with 

 the exception of the large Tenebrionid, Tencbrio molitor, which 

 was in the pupa state in large numbers on May 27th, changing 

 into the imago a few days later. All species of Histeridae were 

 taken under pieces of rotten wood covered by deep laj'ers of 

 damp refuse. Probably the habits of these species account for 

 their scarcity in collections. 



The Latridiidae and Trogositidae were all sieved from Ary 

 accumulated old hay and grain dust. 



The Ptinidae were found in a small annex fornierh'^ used for 

 cattle. The ground W'as a hard dried out conglomeration of 

 manure and dirt, almost like turf ; at first but few specimens 

 were found in it, but finalh% by beating or thumping the ground, 

 both species mentioned below appeared in great numbers. 



Only species of which I have no doubt as inhabiting such 

 places and which were found mostly in numbers are placed in 

 this list. Several species of Carabidae were found, but onh* in 

 single numbers ; as they are probabh' accidentals they are 

 omitted. 



The following is an enumeration of the species found : 



Microglossa sp., common in damp places. 



Xaiitholiims' gularis Lee, common with above sp. 



Olophruni obtectum Er., several examples. This species I have fre- 

 quently found in the immediate vicinity in low meadows. Other minute 

 species of Staphylinidae were taken which I am unable to determine, 



Ptenidiuin evanescens Marsh, common, sieved from damp refuse. 



Sericoderus jlavidus Lee, common, sieved from dry old hay. 



MycetcBa birta Marsh, very common everywhere. 



Aglenus brunneus Gyll., common ; an interesting blind species. 



Silvanus advena Wattl., very common. 



Typhoea futnata Linn., common in damp refuse.
