IV PREFACE. 



to have been windborne. The " Cabbage Moth," also very 

 common and chiefly infesting Cabbage, was fully reported, with 

 specimens accompanying, as occurring to such an injurious 

 extent in caterpillar state for at least two successive years on 

 Pea leafage at a locality in Aberdeenshire, that it appeared well 

 to record it (pp. 103-105). 



Amongst orchard pests the presence of a small Tortrix moth 

 with life-history which, as far as I am aware, had not previously 

 been recorded as troublesome here, was kindly contributed, with 

 specimens for illustration (see pp. 73-78) ; and I was myself able 

 to add some needed material to the life-history of the Pith Moth 

 (see pp. 1-8). 



Some additional and useful information has also been gained 

 regarding the two kinds of Hylesinns, known as the " Common " 

 and the " Greater " Ash-bark Beetle. 



On the whole, I believe I may say that the past season has 

 brought not only an increased number of enquiries, or com- 

 munications, regarding a larger number of infestations than are 

 usually the subject of correspondence, but also that we have 

 made a fair advance in information. 



The following list gives the names of most of the kinds 

 regarding which I was consulted ; but it should be observed 

 that, so far as I am aware from reports sent to myself, there was 

 no general infestation on orchard leafage of the caterpillars of 

 the Winter Moth and allied species, nor in late summer and 

 autumn of what are often known as Turnip Grubs, or " Surface 

 Caterpillars," the larvre of Agrotis segetum and other allied kinds 

 often very destructive to Turnip bulbs, &c. 



Eegarding corn pests, the only kind as to which I have had 

 special enquiry was that of Wheat-bulb Maggot, and on careful 

 search through my books I have not been able to find a single 

 entry of enquiry as to Hessian Fly. This, of course, does not at 

 all prove the pests were not troublesome ; still, I conjecture it is 

 likely that, if they had been prevalent to any important extent, 

 some amount of application regarding them would have been sent 

 to myself. 



I give on opposite page a list of most of the infestations 

 noticed in the past season.
