Insects, etc., Injurious to Currants. 211 



sidering, but spraying for this insect is perhaps better. Any arsenical 

 wash will poison the caterpillars. Just as in previously mentioned 

 enemies so with this one, arsenate of lead will be found the most 

 successful poison spray. Eegarding the time to spray there may be 

 divergence of opinion. Some would leave it until the late spring, 

 when the black and white caterpillars are seen working. We must 

 remember that it is in their early spring life that the chief damage 

 is done. Is it not then better to prevent this by autumnal spraying 

 to poison the caterpillars before they hibernate ? 



Several trials have been made by the writer with the autumnal 

 treatment and no signs of the caterpillars have been seen in the suc- 

 ceeding year. In gardens where currants are trained against walls, 

 fine must remember that the crevices between the bricks are often 

 their winter habitations, and in such cases repointing the walls has 

 been found of great advantage.

THE CURRANT AND HOP PUG MOTH. 



(Eupitliecia assimilata. Gn.) 



The caterpillars of this moth now and again do some damage to 

 all three varieties of currants, and also feed on the hop. The moth 

 is a little more than | inch in wing expanse, the fore wings light 

 blackish-brown, with a grey to almost white line across. It is found 

 on the wing in May and June. 



The larva is yellowish-green, thickly covered with small yellowish- 

 green raised spots, the divisions of the segments yellow and a dark 

 green line along the back and one below it on each side ; the larva? 

 show considerable variation. They are mostly noticeable in September 

 and October. Pupation takes place in an earthen cell in the soil. 

 The pupa is yellowish-green. Spraying in autumn with arsenate of 

 lead would suffice to keep this moth in check, if it ever increases 

 sufficiently to need treatment.
