SHORT NOTICES. 



In my Twenty-third Annual Keport (that is, the first part of 

 my Second Series of Observations of Injurious Insects) I varied 

 from the original plan of arrangement by giving under a special 

 heading of ** Short Notices " such disconnected observations of 

 appearance, habits, treatment, or remedial measures relatively 

 to insects previously referred to (with so much repetition of 

 description of the attack as was necessary to show what was 

 referred to), as conveyed useful information in addition to that of 

 the detailed and illustrated observations given in the previous 

 series of twenty-two Annual Eeports. 



In this manner the points of new information contributed up 

 to date are preserved, possibly to complete the accounts of the 

 various infestations in a future publication ; and meanwhile 

 repetitions unnecessary to the customary recipients of the Annual 

 Reports are avoided. To others who may wish to study the 

 history of any special attack, the information is made available 

 by means of the references at the end of each of the following 

 papers, and also by the General Index, for which see advertise- 

 ments.

Apple-suckers or Apple Chermes. Psylla mali, Schmidberger. 



The attacks of tliis minute insect have hitherto been found very 

 difficult to deal with satisfactorily ; but in December, in 1900, Mr. 

 C. D. "Wise wrote me from the Toddington Orchard Company's Fruit- 

 grounds, Winchcombe, R.S.O., Glos., that they had had great success 

 in clearing this pest from its harbouring places in the trusses of the 

 Apple blossom by powerful application of soft-soap wash. Mr. Wise 

 wrote as follows : — 



" Apple Psylla. — We were successful in spraying for this pest with 

 the soft-soap wash last spring. With our steam spraying apparatus
