Lacnosterna sp. The Common White Grub. The larvse of this 

 common pest were found feeding on the roots of catalpa seedlings in 

 the nursery row on river bottom land near Troy, Ohio, August 23d, 1905. 

 Nearly all the trees attacked died, and in many cases the tap root was 

 severed about one inch below the surface of the ground. Persons plant- 

 ing catalpa seed or young trees should avoid land that has been in sod 

 the previous year, especially if grubs are known to be present.

The work of a leaf miner in Hardy Catalpa leaves was observed 

 at Tippecanoe City, Ohio, on Octorber 16th, 1905. The larva begins 

 the mine as a narrow serpentine passage visible from the upper surface 

 of the leaf only. This portion is continued of a nearly uniform width 

 for about an inch, when it is abruptly enlarged into a somewhat circular 

 blotch mine, usually from one-half to three-fourths of an inch in diam- 

 eter, but a few were observed which were one and one-fourth inches 

 across. Nearly all of the mines were empty when examined, hence the 

 writer was unable to determine the identity of the insects responsible for 

 the injury.
