22 First Report on Economic Zoology . 
regards spraying with Paris green and the importance of “ sticky 
banding ” w r as 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 quite useless for these biting-mouthed insects, and 
also that when Paris green is used animals may be kept under the trees. 
It may also be pointed out that Nyssia zonarict has no importance 
as a fruit pest, feeding only on yarrow and dog-rose, nor is Phygalia 
pilosarict 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 Bibionidce . 
They have no connection with the caterpillars as supposed. These 
dipterous insects belong to the species Bibio marci (St. Mark’s Fly). 
The lar vm 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. liortulcinus have appeared this year, and have been 
sent by numerous other correspondents. 
The Pear Midge. 
(Diplosis pyrivora, Piley.) 
Pear fruitlets sent to the Board from Brackenwaite, Wigton, 
Cumberland, were attacked by the Pear Midge (. Diplosis pyrivora). 
This same pest was reported from Glazebrook, near Manchester. 
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 larvae 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,” 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 
fruitlet. 
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, gooseberry and currant, all supposed to be
