IV PREFACE. 



mentioned about Mangold injury, and no new information con- 

 tributed about attacks on these or Turnip crops. 



Amongst Fruit attacks some notes were sent of mischief 

 caused by the very small caterpillars of the Eye-spotted Bud 

 Moth feeding at the end of Apple shoots amongst the bunches of 

 opening leaves, and blossoms, — an attack which has onW recently 

 been noticed, and on which more observations are needed. On 

 Currant leafage the caterpillars of the so-called Spinach Moth 

 have not been previously reported, and some observations are 

 given on non-transportation of the Black Currant Gall Mite in 

 earth at roots of removed bushes. 



The Pear Gnat Midge attack to very young Pears, which 

 was first noticed as seriously prevalent in 1898, was very little 

 reported, and on special enquiry in 1899, at the localities of in- 

 festation, had been checked very satisfactorily where the requisite 

 treatment had been applied. The Raspberry Moth and Strawberry 

 Ground Beetles also it is found can be kept thoroughly in check 

 by the remedial measures noted. 



Diptera (two- winged flies, and more especially animal flies) 

 were more than usually enquired about ; and of the two kinds 

 mentioned which are not known as doing much harm with us, 

 the rare Red-bearded Throat Bot Fly of the Deer is mentioned 

 as giving another record of presence, and at the great altitude of 

 three thousand feet ; and the Grouse Fly as giving a little more 

 record of its pupal stage, and opportunity for securing a figure 

 (see frontispiece) of the elaborate structure of its foot. The 

 Cheese and Bacon Fly is a severe trade trouble, which I am 

 obliged by practical assistance in bringing forward.
