LETTER OF TRANSMITTAL. 
COLUMBUS, OHIO, October 21, 1886. 
Dear Sir: I forward to-day a few pages of notes on insects observed during the 
few months I have been at work. 
Yours, very truly,

THE STRAWBERRY LEAF-BEETLE. 
(Paria aterrima.) 
This insect began about the middle of August to feed upon the foliage 
of the strawberry beds in the University garden. It was first noticed 
upon the old beds, but soon spread to the new ones, and has done con- 
siderable damage, in some places completely riddling the leaves with 
its minute round holes. At the present date (October 12) it is yet 
busily at work. 
THE STRAWBERRY ROOT-BORER. ee

(Graphops pubescens.) 
exet 
Since the Ist of September the larva of this beetle has been doing 
considerable damage to the strawberry beds, attacking both old and 
new beds, and in some spots destroying as many as 10 per cent. of the 
plants. The grubs are found in numbers varying from two to eight per 
plant either in or near the roots. They work all the way from the crown 
to the lower part of the roots, eating in slight channels, which are left 
full of chips and castings. The grubs never, so far as I have noticed, 
bury themselves deeply in the fleshy part of the root, but prefer to work 
along the sides. Frequently a dead plant may be taken up whose roots 
show their work plainly, yet none of the larvze are present in it. Ex- 
amination of the soil around the plant will, however, reveal the little 
fellows. I have observed a great number in position feeding. Up to 
date (October 20) no pups have been found.
