floating logs. Among the leaves near the water Bradycellus 

 linearis was common. It was often found among leaves on ground 

 that had been covered with water for several days or weeks at a 

 time. Loxandrus, of which there were several species, did not 

 seem to object to water either. They were everywhere in the 

 wet woods. 



Coptodera izrata Dej. was taken once under bark, and the 

 bright little Hister ceniomicans Horn and venustus Lee. were dug 

 from crevices in oak bark. Dicerca lurida Fab. might have been 

 gathered by the pint. Sometimes a whole handful was taken 

 (but not kept) from under the loose bark of a large tree. 



Burnt over districts in the woods yielded many Platynns er- 

 rans and Cryptobium sp. Pinophilus (jopacusf) was the most com- 

 mon of all the Staphylinidae. 



To the kindness of Mr. Henry Ulke I am indebted for the 

 names of the above species.

RAVAGES OF THE LOCUST BORER. 



By PHILIP LAURENT, Phila. 



On September iyth of the present year my neighbor, Mr. 

 Horace Rodd, called my attention to a grove of young locust 

 trees (Robinia pseudacacia) growing a short distance from his 

 home at Mt. Airy, Pa. The trees varied from one to six inches 

 in diameter, and not one of them but what showed the distinctive 

 work of the locust-borer {Cyllene robinia}. Many of the trees 

 were completely honey-combed by the larva of this destructive 

 beetle. With the aid of Mr. Rodd I secured sections of some 

 of the trees, some of which are represented on the plate accom- 

 panying the present number of the NEWS. Figures i, 2 and 3 

 (read figures beginning from upper left hand corner) were cut 

 from a tree five inches in diameter that had but lately succumbed 

 to the ravages of the borer. The other figures represent sc- 

 tions cut from limbs and branches; no part of the tree is exempt 

 from their attacks, excepting the smaller twigs and leaves. In a 

 field close by I found the beetle feeding on the golden-rod (So- 

 lidago}, there were hundreds of them; in some cases I counted 

 as many as ten specimens on one stalk of golden-rod. For 

 many years the locust borer and hickory-borer were thought to
