HOP-VINE SNOUT MOTH ; RED SPIDER. 135 



Prevention and Remedies. — Stuong syringing, by means of 

 the engines, with some of the regular Hop-washes, or with the 

 common fish-oil soft-soap procurable at ten to twelve shillings 

 per firkin of sixty pounds, appears to be one of the best 

 remedies known. The soft-soap makes the Hop-bines 

 unpleasant to the caterpillars, and, if applied as soon as any- 

 large number of the moths were seen about early in the 

 season, would probably deter a large proportion from laying 

 eggs on the syringed plants. 



Jarring the poles is also recommended, so as to make the 

 caterpillars (which loose hold on a slight shake) fall to^ the 

 ground ; but the difficulty in this method of treatment is to 

 keep them from going back again up the plants. TrampHng 

 on them, throwing soot, lime, &c., or, in bad cases of attack, 

 shaking them into something placed below or on to tarred 

 boards, are recommended. 



Hand-picking the leaves with the moth-cocoons inside gets 

 rid of much of the second brood, and these cocoons are also to 

 be found about the stems of their various food-plants, on the 

 surface of the ground, or in sheltered nooks. Clearing away 

 plant-rubbish generally, and more especially the Nettle on 

 which this caterpillar feeds, would be of service.

The " Red Spider," which causes enormous damage in dry 

 seasons to the Hop-crops, is neither an insect nor (properly 

 speaking) a spider. Strictly speaking, it belongs to the 

 " Spinning Mites," * and the figure gives a greatly-magnified 

 view of the long stiff hairs on the feet with globular formations 

 at the tip, which are of use in spreading their webs. 



The egg is oval, or spherical, and colourless, and may be
