SCIABA. S. pyri, Small Pear Midge. 

 8. Schmidbergeri, Large Pear Midge. 

 When a fallen pear is cut open, it is 

 often found core-eaten, and with a brown 

 powder marking the progress of the 

 assailant. This is caused by the larva 

 of these insects. The midges appear 

 early in July. The Small Pear Midge 

 has club-shaped halteres, the club dark 

 brown, and the stem whitish. When 

 alive, the abdomen is of a lead colour, 

 with black wings. The head and thorax 

 are black, as are also the antennae ; the 

 palpi are of a pale yellow, the feet whitish,, 

 and the tarsi black. 



The Large Pear Midge appears about 

 the same time as the preceding. The 

 female is little more than a line long, 

 and half a line thick, also much larger 

 than the smaller pear midge ; the male is 

 more slender, and somewhat shorter. 

 The antennae are blackish, and not so 

 long as the body. The head is black and 

 shining, as is also the thorax ; the pro- 

 boscis ash-grey, the abdomen of ttie male 

 a deep black, that of the female browner, 

 with black wings; the anal point, how- 

 ever, is quite black, the feet ash-grey, 

 and the tarsi and wings black. They 

 both survive the winter, and deposit their 

 eggs in the blossom, when it opens in 

 early spring. The larva eats its way into 

 the core of the young fruit, and again 

 eats its way out at one side when the 

 time arrives for it to bury itself in the 

 ground, and pass into the chrysalis form. 

 Kollar.

 Nat. ord., Lilyworts [Liliaceee]. Linn.,
