316 The Scottish Naturalist. 



or oblong, pale green, or purple checked, smooth, of the size of 

 a pea, or larger, situated on the twigs, chiefly those issuing from 

 the main stem. The inside is fleshy or fibrous, and is occupied 

 by colonies of slender orange spindle-shaped maggots, from ten 

 to twenty in number. The maggot is scarcely a line long, 

 puckered along the edges, truncate behind, where it is trilobate, 

 the middle lobe projecting. The mouth is indicated by a 

 decided black spot ; the two front spiracles are prominent like 

 a pair of horns ; the underside is roughish. When extracted it 

 is very lively, rolls about, and leaps repeatedly. The oral hooks 

 being caught in the anal lobe a circle is produced, which snaps, 

 and up it springs. I first observed it in Ladykirk Churchyard, 

 June 28th ; again in the manse garden at Cockburnspath ; and 

 a few days afterwards in Tynningham Woods. The gall-midge 

 has not been described. 



Sirex Gigas. — An example of this fine insect was captured 

 at Houndwood by Miss Coulson. It is the second instance for 

 Berwickshire, and the fourth for the district. 



Hornet ( Vespacrabro). — Mr. j. S. Dudgeon writes that when 

 shooting near Gordon in autumn he noticed a Hornet, of which 

 he was certain, from his acquaintance with it during a residence 

 in the south of England. Wallis records it for Northumberland, 

 but it is singular that it should evade the systematic observation 

 of modern times. 



There are many other notes in the volume which we would 

 have liked to have extracted, but as we have already trespassed 

 upon the space which should have been otherwise occupied, 

 we must refrain.
