ground, but that it has escaped observation. We have 
scarcely a dozen entomologists who collect oak-galls, and 
therefore many species will of necessity escape notice.—

APHILOTHRIX SIEBOLDI. 
Aphilothrix Sieboldii.—This red or reddish brown gall is 
found under or near the surface of the ground, on twigs that 
are one centimetre or one and a half centimetre in diameter. 
It seldom occurs alone, but numbers of them are usually 
found crowded together, and the twig may possibly attain a 
diameter of three centimetres. The gall itself is conical: it 
stands from five to six millemetres in height, and its
