148 ANNUAL KEPORT. 



THE STRAWBERRY SAWFLY. {EmpJiytus maculatus, Norton.) 



This pesb of the strawberry plant has also been brought to my 

 notice by Mr. Gibbs, for whom it did much injury last spring on a 

 new bed of the Wilson variety. 



The larva of this sawfly is a slender, semi-transparent green slug 

 worm about three-fourths of an inch long which when not feeding 

 rests coiled up on the under side of the leaves. When mature these 

 slugs burrow into the ground to the depth of an inch or so and 

 form a frail cocoon of silk and particles of earth. The flies appear 

 late in July and lay the eggs from which the second brood of slugs 

 hatch in August. This insect is not so common as many other 

 enemies of the strawberry, but is sometimes very destructive. It 

 is however, easily killed with hellebore applied dry or in water. 

 Paris green in liquid suspension may also be freely applied to the 

 second brood in August. 



In concluding this paper, I wish to say that ill-health and busi- 

 ness demands make it impossible for me to make extensive investi- 

 gations of the insects occurring in distant parts of the state, but I 

 shall always be glad to have my attention called to them by cor- 

 respondence, and would suggest that where inquiries are made 

 concerning any species, that specimens of the insects be packed 

 in tin or wooden boxes to accompany the latter. 



DISCUSSION OF THE ENTOMOLOGICAL REPOBT, 



Mr. Latham. There is a steel blue beetle that eats into the buds 

 of the grape. I would like to have it reported on at some future 

 time by our entomologist. As to insecticides, white hellebore is 

 effective if pure. 



Mr. Whipple. Only one kind of cabbage worm is treated of in 

 the report. There is another, a long worm, with bright stripes. 



Mr. Mendenhall. I think the characteristics of one kind are 

 largely the characteristics of all the rest. 



Mention was made by some member, whose name the reporter 

 did not hear, of a new potato bug that threatens to be destructive 

 in Dakota. 



Secretary Gibbs. From the description given I presume it is 

 the same bug that Mrs. Underwood mentioned at our meeting in 

 June, 1882, as appearing on her flowering plants. It is a long.
