LETTER OF TRANSMITTAL. 



Columbus, Ohio, October 21, 13S6. 



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, 



WM. B. ALWOOD.

U. S. Entomologist. 



THE STRAWBERRY LEAF-BEETLE. 



(Paria aterrima.) 



This insect begaii about the middle of August to feed upon the foliage 

 of the strawberry beds iu 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. 



( Graphops pubescens.) 



Since the 1st of September the larva of this beetle has been doing 

 considerable damage to the strawberry beds, attacking both old and 

 uew 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 larvae are present in it. Ex- 

 amination of the soil around the plant will, however, reveal the little 

 fellows. I have observed a great number iu position feeding. Up to 



date (October 20) no pupae have been found.
