^* This little gall is undescribed. In company with Mr. H. F. Bassett, of Waterbury, Ct., I found it so abundant, last month, that the acorns were very generally destroyed. Strange as it may appear from observations made by Mr. Bassett, this gall will, in all probability, prove to be but the summer form of the wooly gall known as quercus operator—so little do we know yet of some of Nature's secrets!
