 The following note relating to perhaps the most common and inju- 

 rious plant-louse known to the vegetable garden, was received from a 

 correspondent in Lacey ville, Ohio : 



Inclosed I send you a piece of a leaf from a rutabaga turnip. The 

 insects, like those on the leaf, attacked my crop of turnips when the 

 bulbs were about one-fourth grown, and arrested further growth. 



The tops are now nearly destroyed, and the crop almost a failure. 

 I tried dusting with plaster, but it did no good. Please tell me what 

 this is, and if there is any remedy. 



^Tien going after the turnip leaf, I crossed a young apple orchard, 

 and cut the inclosed twig from one of the trees. 31any of the trees 

 were infested in the same way. H. L.
