22 First Report on Economic Zoology. 



regards spraying with Paris green and the importance of " .sticky 

 banding" was called attention to. 



Information concerning this pest is given in leaflet No. 4 ; but it 

 should be pointed out that the use of quassia or soft-soap wash is 

 now known to be qiute useless for these biting-mouthed insects, and 

 also that wlien Paris green is used animals may be kept under the trees. 

 It may also be pointed out that Nyssia zonaria has no importance 

 as a fruit pest, feeding only on yarrow and dog-rose, nor is Phygalia 

 jyilosaria found on fruit-trees, its food plant being the oak. 



The Winter Moth was also reported as damaging the leaves of 

 apple and pear at Glazebrook, near IManchester. 



The same correspondent sent some flies belonging to the Bibionidce. 

 They have no connection with the caterpillars as supposed. These 

 dipterous insects belong to the species Bihio marci (St. Mark's Fly). 

 The larva? live in the soil and somewhat resemble small " leather- 

 jackets " ; usually they occur in masses, and seem to do no little 

 harm to the roots of grass and other plants. Great numbers of this 

 species and B. hm-tulanus have appeared this year, and have been 

 sent by numerous other correspondents. 



The Pear Midge. 



{Diplosis jjyrivora, Eiley.) 



Pear fniitlets sent to the Board from Brackenwaite, Wigton,. 

 Cumberland, were attacked by the Pear Midge {Diplosis pyrivora). 

 This same pest was reported from Glazebrook, near IManchester. 

 It is interesting to note the northern extension of this pest and its 

 much later period of reaching the mature larval stage in the north. 

 Drenching the ground under the trees vnt\\ paraffin emulsion either 

 when the larvse are falling or as the flies are hatching out is most 

 beneficial. An unobserved feature in the attack of this pest may 

 here 1)e mentioned. When the fruitlets are " struck by the fly," they 

 swell much more rapidly than the sound ones, and can thus always 

 be told on the tree by their being often twice the size of a healthy 

 fruitier. 



Scale Disease and False Scale amongst Fruit 

 Trees and Bushes (Apple, Pear, Gooseberry, 

 Currant, etc.). 



Specimens sent to the Board of Agriculture from Hayling Island 

 of apple, pear, quince, goosebeny and currant, all supposed to be
