body has minute hairs thinly scattered over it. On the sides of the head, 

 which is small and black, there are bristle-like palpi, pointing forwards 

 The larva is full fed by the end of August.

Pupa, dark brown, about 9-100 

 of an inch long. The antennae 

 cases form a striking feature, project- 

 ing on either side about one-sixth the 

 length of the pupa, and giving a flat- 

 tened appearance to the head. A pair 

 of setae mark the position of each 

 spiracle, and there is a rounded pro- 

 Pj,, 2j; tuberance at the hinder extremity. 



Imago. — Wmgs, semi-transparent — beautifully opaline — three-ribbed 

 — having the form of the blades of a propeller — fringed with long hairs. 

 Balancers conspicuous. Antennce, setaceous, 24 jointed, having a circlet 

 of hairs around each joint. Eyes, large and black. Thorax, reddish 

 brown, with a peculiar hump on the back, behind the wings. Legs, long 

 and hairy. Abdo^neii, salmon-colored — has two lines of hairs extending 

 lenthwise on the under side. The perfect insect appears early in 

 September. 



[This insect was reared by us about the same time as those by Mr. 

 Fyles. It was very common in the neighborhood of London this year, 

 infesting the gall-inhabiting type of the Phylloxera. The following notes 

 in reference to it may be of interest, omitting the description already 

 so well given by Mr. Fyles : 



About the middle of August my attention was directed to the foliage 

 of some grape-vines, Clinton and other varieties, which were suffering from 

 an attack of the gall-inhabiting type of Phylloxera. On opening some of 

 the older galls they were found to be free from living lice and occupied by 

 one, or in some instances two, small, brown chrysalids, and a number of the 

 empty skins of the young lice. On further examination many of the galls 

 were found to contain the larvae of this same insect.
