this Eecl Spider, tlie Tefrani/rJi/is, can at once be told from one of the 

 nou-web-weaviu;4 Ilri/ohins. Tlic \\'intur appears to ))e ])assi.'d in two 

 ways under glass, uanieh', in the egg stage ou the Wdod and buds, 

 but more usually as immature or mature mites under tin- sidn of the 

 wood or in any convenient shelt(:'r.

This consists of cither washing, dusting, or fumigating. 



i;ed Spider strongly object to Cdld water, and frequent syringings 

 in an early stage oC attack with plain ^\'ater will often stave off attack, 

 but it is useless when any 

 amount of webliing has 

 been formed. Spraying 

 with liver of sulphur and 

 soft soap is generally of 

 benefit, but by far the best 

 method is fumigating Avith 

 sulphur. An old and ex- 

 cellent plan, if done care- 

 full}' and at the exact 

 temperature (the knowledge 

 of -which seems to be gained 

 only by experience), is to 

 l^aint the stove pipes with 

 tlowers of sulphur. At 

 times damage is done in 

 this Avay, depending, it 

 seems, entirely on the heat 

 of the pipes and house. It is better to use sulphur fumes spread 

 )jy means of proper machines, such as that made by Campbell of 

 ilauchester. 



Very inferior results have Ijeeu obtained with hydrocyanic aciil 

 gas, and sulphur fumigation seems to be the best remedy we yet have.
