10. THE lkaf-minim, hi.-pa. 
Odontoid rubra Weber. 
Mr. \Y. L. Devereaux writes us from Clyde, X. Y., that this beetle 
11 is a very conspicuous pest here, destroying the eutire foliage of every 
s-wood iu many forests, excepting trees of great height." 
11. The linden gai.l mite. 
Phytopius abnormis Garman. 
Produces galls on the leaves of the American linden or bass-wood, Tilia americana 
Linn. 
The transverse striae of the abdomen number about 56. This mite 
differs from all the other Phytopti I have seen iu that the abdomen, 
just before the terminal sucker, is noticeably enlarged. But few speci- 
mens have been examined, as they have been very rare. In many 
of the galls, comparatively large, elongate eggs occur, which probably 
belong to some larger mite which preys on the gall-mites. 
The gall is top-shaped, expanding above and contracting towards 
the upper surface of the leaves into a neck. It measures .155 inch in 
height, and .100 inch in diameter. The walls are deeply infolded, 
sometimes giving rise to unequal lobes. The outer surface is smooth, 
green and devoid of hairs. The cavity of the gall is made unsym- 
metrical by the deeper impressions of the wall. The iuside of the 
latter is slightly roughened by small folds, and is clothed with long 
aciculate, unicellular hairs. These galls occur sparingly on the leaves 
of large trees in open woods at Bloomiugton, 111. (H. Garman iu
