A NEW GRAPE-VINE PEST- Our attention was called by Mr. F. Garri- gus, of Santa Clara, to the ravages of some sort of a small bug, flea or fly that had at- tacked Mr. Norman Porter's vineyard which is situated upon chimasel land near the foot of the mountains at the west of our valley. Also, Mr. D. C. Feeley brought to our oflice some of the same sort of insects, that he said were attacking a small vineyard not his own in the foot-hills of the same range. Af- ter a look at the insects through a microscope, we rode over to the Porter place, and in com- pany with Mr. Stone, who has charge of the farm and who kindly assisted us in bottling a few more of the bugs, we made a close obser- vation of the habits of the insect throughout the vineyard. Then at home we again exam- ined with the microscope.

The young bugs, when first hatched, look like tiny, light-colored spiders. As they get larger they more nearly resemble the green aphis in shape, not in color, and do not get wings aijparently till the last shed- ding of the skin. They work in groups and where they attack a vine they first tap the largest leaves and the bark near the base of the' new growth of wood, and invariably take the tenderest new growth last, seeming to prefer a growth nearly matured to the tender new shoots. They will cluster thickly upon whatever they attack. As they rest upon the vines their heads are always towards the ends of the vines, and
