to the genus Lachnosterna. Even the recently hatched grubs pre- 
sent practically the same characteristics as the nearly full-grown 
individuals so numerous occasionally under sod which has been 
killed by these pests. The principal difference is that the smaller 
grubs are whiter, owing to the fact that there is proportionately 
less dark vegetable matter within the small body.

Injuries in 1912. Many pastures and meadows as well as cer- 
tain cultivated crops in Albany, Columbia and Rensselaer coun- 
ties at least, were very severely damaged the past season by white 
grubs, and similar injury was reported from portions of Wash- 
ington county. The pests were so prevalent in the southern part 
of Rensselaer county that most of the grass roots were cut off 
over considerable areas; in some instances grass on half an 
acres or even larger fields was totally destroyed, the sod being torn 
up wherever the horse rake was used. Such conditions were com- 
mon in the towns of Schodack, Nassau and Kinderhook, to 
mention only a few localities where personal investigations were 
possible. Similar injury was reported by William H. Wan- 
zer from Slingerlands near Hurstville in Albany county. The 
grubs not only devoured all the grass roots but frequently at- 
tacked those of nearby shrubs and trees, while rose bushes in one 
area were so badly eaten that the plants were readily torn from 
the ground. Mr B. D. Van Buren informs us that on his farm 
at Niverville the roots of a recently set apple tree were so badly 
eaten that it was easily pulled up. Corn planted on infested sod 
land was destroyed, and in one such locality a sample digging in 
October resulted in finding thirteen living grubs in an area of
