Insects A^eding the Strawberry.

The Root-worm Beetle. Paria aterrima, Oliv. 



Order Coleopteru, Family Chrysomelidse. 



This beetle, probably the imago or adult of the root-worm, will be fully 



described and discussed under the latter name, and I need only mention here 



the fact that it appears on the vines in both spring and summer (August), 



and that it may be poisoned at the latter period without trouble, as has been 



, several times proven by exjjeriment. 



Locusts. Caloptenus spretus, Thos., Acridium americanum, Drury, etc. 



Order Orthoptera, Family Acrididae. 



Prof. Riley mentions strawberry leaves as among the favorite food plants 

 of the Rocky Mountain locust (Seventh Report, p. 159), and we have found 

 the young of the second species above mentioned devouring the strawberry 

 leaves in Southern Illinois. Mr. F. S. Earle, of Cobden, 111., writes in July : 

 "A few days ago I noticed some ' flocks ' of young grasshoppers [probably of 

 this species] that were literally eating up some strawberry plants. They 

 were quite small, apparently just hatched, and there were not enough of 

 them to do any serious harm, but they made a clean sweep as far as they 

 went." 



The Strawberry Plant-louse. Siphonophfyra Jragarise, Koch. 



Order Hemiptera, Family Aphididse.

This species occurs in numbers large enough to attract attention and occa- 

 sionally to do decided injury, in Kansas and Illinois, *and probably elsewhere 

 also. Like all the plant-lice, it is far more dangerous than its usual insignifi- 

 cance would lead one to suppose. The reproductive rate of these insects is 



-The form figurert above, from Southern Illinois, ha*; the aspect of an Aphis, and it is 

 possible that the Illinois species is not iii'phonophoni framirhi', as was supposed by Dr. Thomas. 

 Until the aerial forms can be seen, however, 1 prefer to leave the matter as above.
