trees on which they were introduced, although they had been in the 

 orchard siuce the spring of 181U. All of the trees that the scale was 

 found on came from a New Jersey nursery, but it was certain varieties 

 of trees only that were infested, the Idaho pear beiug the principal and 

 almost only one infested, while in some instances hundreds of trees 

 purchased at the same time and of the same nursery were found, after 

 a careful search, to be perfectly healthy and free from the scale. 



My instruction in each case where I have been consulted has been to 

 grub up and burn every infested tree, and so far as I can learn this 

 has been done. 



There are doubtless other localities in the State, however, where the 

 scale occurs, but where it has not been recognized, so that every effort 

 will be made to find other localities and to prevent the spread of the 

 pest in the State. 



The scurfy bark-louse (Chionaspis furfurus). — It would appear that 

 this scale is quite common and widely distributed in this State, since it 

 has been sent in from many different sections. The oyster shell bark 

 louse is also common and quite destructive in some sections, principally 

 within the range of the transition zone. 



The rose scale, the plum scale, and other insects, and even twigs the 

 bark of which was covered with prominent leuticels, were sent in by 

 persons who thought they might be the dreaded San Jose scale. 



Cutworms (not the Hopkins variety of newspaper fame, but those 

 having normal transformation and feeding habits) were exceedingly 

 common and destructive in our State in the spring and early summer 

 of 1895, but, as was predicted, they gave comparatively little trouble 

 the past spring. This scarcity of the pest this year is due, I think, 

 largely to the abundance last year of an Apanteles parasite that 

 emerged from the cutworms in enormous numbers. So abundant were 

 the conspicuous yellow or white bunches of the cocoons on grass and 

 grain stubble and on weeds and grass in pasture fields near Morgantown 

 and other localities visited last summer that in places I could count- 

 hundreds of them within a radius of a few yards. 



The webworms (crambids,). — These insects attracted general atten- 

 tion for the first time last year, and were serious pests in cornfields 

 and gardens. 



The harlequin cabbage bug has proven to be a serious pest in certain 

 sections of the State within the past few years. It was quite destruc- 

 tive to cabbage in the experiment station garden last year, but scarcely 

 a single example has been observed this year until quite recently. 

 Whether or not this early absence of the bug is due to the late fall and 

 winter plowing of the garden I can not say, but it would appear that 

 such may be the fact. 



Blister beetles as enemies of China asters. — Last summer a fine bed of 

 assorted and rare China asters growing in the experiment station 

 flower garden was literally ruined by the black blister beetle (Epicauta 

 pennsiflranica) within a day or two after the flowers began to open. It
