All that is iiecessavy as far as present attacks have gone is liaiid- 

 jiickiiig the caterpillars. Should tliey ever occur in such large 

 numbers as I have seen them in osier beds in iliddlesex and 

 Huntingdonshire, tlien spraying with arsenate of lead would prii\'e 

 successful.

THE APPLE CLEARWING. 



(./i'i/('ri(( m'l/ii/iiforinis. Bork.) 



Ou the 21st of June, 1907, larva' and pupa' of tliis Clearwing 

 Moth were sent me i'rom the (_'roydon district by the Seci'etary of 

 tlie Horticultural j\Iutual Improvement Society {'■''). 



The larva' were taken out of an apple tree, AVaruer's King, 

 where they had been working havoc underneath tlie bark. They 

 occurred in patches. In many instances they were found in the 

 y\-ounds caused by Woolly Aphis. 



" The attacked trees are about sbx years old," wrote the Secretary. 

 'My. Boshier, " and are in good bearing condition." 



On the '.^tJth of June a further lot of pupa'' were sent, taken from 

 Puchess Favourite, Warner's King, Colonel ^\augllan and ^^'inter 

 t^lueening. The lar\'ie were mostly found 

 aliout 7 feet from the soil. 



This Clearwing Moth (Fig. 2) is some- 

 what similar to the Currant Clearwing in 

 general appearance, but can at once be told 

 by tfie broad I'cd lielt on the abdomen. 

 The length is about 20 mm., with a wing 

 expanse of 22 to 2.5 mm. The head, thorax 

 and body are black ; the latter has a bright 

 red band above, white beneath in the male ; 

 in the female the underside is only edged 

 with white; the tail fan is black. The wings are transparent, with 

 dark sealed areas. The moths Hy by day, and are found in May, 

 June and July.
