March, 1918.] RoBINSON : BEETLES COLLECTED IN VIRGINIA. 31 



At a shady spot where a little stream breaking? throuj^h these hills 

 supplies a clear pool to which the farm hands resorted for their mid- 

 day rest, there stood a black oak a foot or so in diameter and some 

 thirty feet in height. Under this tree horses had been fed and they 

 had browsed down the underbrush, making about it a small opening. 

 Finally, some thoughtless boy had chopped a belt around the tree and 

 killed it. This had been. done about the middle of May, as the with- 

 ered leaves which still clung to the twigs had not reached full size 

 when death overtook them. 



I visited the spot first on July 9 and took a number of beetles, but 

 did not pry off any of the loose pieces of bark, as I was expecting a 

 visit from Mr. Wm. T. Davis and wished to defer a thorough ex- 

 amination until I could make it in his company. On July 12 we visited 

 the tree together and took some thirty-odd species, and on July 23 I 

 passed by late in the afternoon and took a few more. 



My list follows: 



Carabid.e. 



1. No. 657, Amara impuncticollis, 5 taken under debris at foot of 



the tree. 



2. No. 904, Coptodera aerata, very abundant in crevices in the bark.

3. No. 3017, Sacium lunatum, several taken.

8. No. 3285, Penthelispa reflexa, two. 



9. No. 3287, Bothrideres geminatus, eight.
