22 First Report on Economic Zoology. 



regards spraying with Paris green and the importance of " sticky 

 banding " "vras called attention to. 



Information concerning this pest is given in leaflet Xo. 4 ; but it 

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

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

 also that when Paris green is used animals may V)e kept under the trees. 

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

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

 Ijilosaria 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 Manchester. 



The same correspondent sent some flies belonging to the Bihionidce. 

 They have no connection with the caterpillars as supposed. These 

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

 The larv?e live in the soil and some's^diat 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'tulamis have appeared this year, and have been 

 sent by numerous other correspondents. 



The Pear Midge. 



{Diplosis jpjjrivora, Ptiley.) 



Pear fruitlets sent to the Board from Brackenwaite, Wigton, 

 Cumberland, were attacked by the Pear JMidge {Diplosis jtyrivora). 

 This same pest was reported from Glazebrook, near ^lanchester. 

 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 with paraffin emulsion either 

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

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

 here be mentioned. When the fruitlets are " struck by the fly," the^ 

 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 

 fruitlet. 



Scale Disease and False Scale amongst Fruit 

 Trees and Bushes (Apple, Pear, Gooseberry, 

 Currant, etc.)- 



Specimens sent to the Board of Agi'iculture from Hayling Island 

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