FIELD NOTES. 



By C. W. STROMBERG, Galesburg, 111. 



In the Winter time when the entomologist has to stay at home, 

 after his material results from his Summer's work have been ar- 

 ranged and labeled up, what is a greater pleasure than to get 

 down entomological publications and go over them again and 

 again ? 



Field notes are always interesting. Dr. Hamilton cannot write 

 too often, and I think most of us must enjoy following Mr. Wick- 

 ham about in his travels after Coleoptera. Messrs. Hubbard 

 and Schwarz's articles are most instructive and entertaining, and 

 there are many others. Such notes undoubtedly contribute to- 

 wards keeping up an interest in Entomology with many of the 

 younger and some of the older entomologists. Sometimes we 

 come across notes on Winter collecting. I have been quite suc- 

 cessful at that season of the year in the past, and will mention a 

 few items. 



In an old hollow sugar-maple which stood near the edge of a 

 strip of woods which was comprised mostly of blue ash and white 

 elm, and which was bordered on one side by a piece of prairie, 

 the following species of Coleoptera were taken: In the first place 

 the fine rotten wood in the bottom (inside) was raked out and 

 examined, which yielded more than a dozen specimens of Apho- 

 dius oblongus Say, a large number of Dendrophilus punctulatus 

 Say, five specimens of Corymbites sulcicollis Say. After the dust 

 was examined a large portion of the heart of the tree, which 

 was loose and honey-combed, i.e., eaten by ants and other in- 

 sects, was broken into bits over a piece of cloth. It yielded 

 several specimens of Adelocera impressicollis Say, two specimens 

 of Adelocera marmorata, and one specimen of Adelocera ai'ita 

 Say. The only specimen I have ever seen. There were more 

 than twenty specimens of Thaneroclerus sanguineus Say, two 

 specimens of Clerus ichneumonius Fab., three specimens of Der- 

 mestes lardarius Linn., Tenebrio castaneus Knoch, and T. tenebri- 

 oides Beauv. several of each. Next in order was the outside of the 

 base, which had not been molested so far. The bark was loose 

 at the edges, and each large flake seemed to be partly kept in 

 place by a large amount of spider-web, white patches, egg-sacks, 

 etc., which are generally found about old trees. When this was
