last year. Can this have diminished them ? [Yes, 

 undoubtedly so. — Eds.] 



Hyphantria textor commences in May, and con- 

 tinues to appear through August and perhaps Sep- 

 tember. It is very abundant and omnivorous, or 

 nearly so. 



Is our Thrips in the vineyards, the Tettigonia 

 vitis f (vide Harris.) [We should think not. Thrips 

 and Tettigonia are two very different insects, be- 

 longing to different suborders, and cannot be con- 

 founded. Send us specimens of the " Thrips" for 

 more definite information. — Ecs.J 



Next year will be Locust time here, and we have 

 found some larvaj coming toward the surface, a few 

 exposed in plowing and digging. 



Have you learned the period of larvae of Melo- 

 lonthian, called White Grub, common in sod-lands? 

 [Not definitely. Harris says : " At the close of 

 their third summer (or, as some say, of the fourth 

 or fifth) they cease eating, and penetrate about 

 two feet deep into the earth," to assume the pupa 

 state. — Eds.] 



Rose-bugs are rare here, one or two pairs ob- 

 served annually. I kill them. 



Selandria rosse has made its appearance here 

 within two years ; it is very plenty a degree north 

 of us but increasing here. S. cerasi is scarcely 

 known on pears and cherries.
