cylindrical form which the larva inhabits. The moth is black with some 

 white spots on the wings and white fringes — a beautiful little creature. 

 There are two broods during the year. When disturbed the lively cater- 

 pillar drops instantlv out of its case and falls to the ground; hand-pick- 

 ing is therefore difficult, but the increase of the insect may be checked 

 by burning the leaves in the fall.

The Grape-Vine Geometer (Cidaria diver sUineata), Fig. 46, is a pale 

 yellowish-green looper or measuring worm, which develops into a pretty 

 yellow moth with fore-wings crossed and recrossed with darker lines. In 

 June these caterpillars are sometimes numerous, but may soon be over- 

 come by the Paris green treatment. 



The Yellow Woolly-Bear (Spilosoma virginica) will feed upon 

 almost any kind of plant, but seems to particularly relish the leaves if 

 the grape. The hairy caterpillar must be very familiar to every one. The 

 moths are soft, pure-white creatures with a few black dots on the wings 

 and orange bands and black spots on the body. , 



Several species of climbing Cutworms (A~rotis), Fig. 47, attack the 

 buds and foliage of the grape. They are nocturnal in their habits and are 

 therefore not often seen upon the vines. During the night they come out 

 of their hiding-places, climb up the vines and devour the leaves. The 

 best remedy for them is a mash of poisoned bran made by slightly mois-

tening 25 pounds with water in which some sugar has been dissolved, 

 and then adding 4 ounces of Paris green ; the poison should be gradually 

 dusted on the top and stirred all the time, otherwise it will sink through 

 the bran at once and be ineffective. A handful or two of the mash should 

 be placed at the base of each vine. When the caterpillars come out thev
