84 PEAR. 



In grass orchards the only way of lessening infestation when present 

 appears to be beating down the beetles on tarred cloths placed below ; 

 this answers to some extent in lessening the vast numbers of the 

 nearly-allied bright little golden yellow, or bluish, or green beetles, 

 Phylluhius maculicurnis, which sometimes infest the leafage of orchard 

 (as well as other) trees. But this shaking down should be done in the 

 morning or evening, or when the weather is dull and still, or else, if 

 the sunshine is bright with a warm temperature, the beetles may very 

 possibly take wing, on shaking being applied, instead of falling, as 

 was intended, on the tarred cloth below. 



In regard to the life-history of P. ohlongus, it is considered that the 

 female lays her eggs in the earth during June, and that the maggots 

 hatched from these feed on the roots of different kinds of plants, and 

 after passing the winter in the ground come out in beetle state in the 

 following spring, but as yet no observations of this part of the life- 

 history of the infestation, as noticed in this country, have been 

 contributed. 



PEAR. 



Pear Gnat Midge. Diplosis pyrivora, Riley ; Cecidomyia nigra ?, 

 Meigen and Schmidberger ; C. pyricola?, Nordlinger. 



Diplosis pykivoea. — Female, magnified; lines showing natural size. Larva and 

 pupa, magnified. Abortive Pear. Gnat and pupa, after Prof. Eiley. 



During the past season the attack of the Pear Gnat Midge has 

 been more prevalent and seriously injurious to the young fruit than 

 in any year since 1883, when its presence was first entomologically 

 recorded, though not to any great extent, in this country. 



The dates of inquiry ranged from May 13th to June 16th, and the 

 localities written from ranged over a considerable area of the more
