two first in pairs, the remainder in threes. The larva has the habit of holding itself 

 erect, by means of peculiar anal protuberances which seem to cling by suction. The 

 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. 



In the accompanying figure, drawn by myself from 

 nature, the larva is shown at a, the pupa at 6, and 

 the imago at c, all highly magnified. The natural 

 size of the perfect insect is given at d. 



Pupa, dark brown, about 9-100 of an inch long. 

 The antennse cases form a striking feature, projecting 

 on either side about one-sixth the length of the pupa, 

 and giving a flattened appearance to the head. A 

 pair of setae mark the position of each spiracle, and 

 there is a rounded protuberance at the hinder ex- 

 tremity. 



Imago. — Wings, semi-transparent—beautifully opa- 

 line — three-ribbed — having the form of the blades of 

 a propeller — fringed with long hairs. Balancers con- 

 spicuous. Antennse, 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. 

 Abdomen, salmon coloured — has two lines of hairs extending lengthwise 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 neighbourhood 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. The egg is deposited by the parent fly in the gall, or at its 

 entrance. Each gall is usually occupied by several full grown lice, and from 50 to 500 

 minute yellow eggs, which are gradually deposited and as gradually hatched. The young 

 larva of our new found friend is very active, and groping about within the hollow of the 

 gall, seizes on the young lice as hatched and sucks them dry. We could find no evidence 

 of its attacking the parent lice, as long as the newly-born and tender progeny were in 

 suflicient abundance £o furnish it with a constant supply of fresh food. In some instances 

 one larva, in others two were found in a single gall ; but in no instance have we found 

 living lice with the chrysalids, an evidence that this insect does its work thoroughly. 

 A sufficient number of galls have not yet been examined to determine with any accuracy 

 the proportion occupied, but they appear to be sufficiently numerous to materially check 

 the increase of this destructive pest." — Ed. C. E.] 



COLLECTING IN EARLY WINTER. 

 By James Fletcher, Ottawa, Ont. 



Nov. 13, 1882. 



The unusually mild and balmy weather that we have been enjoying for the last week 

 has made it an easy task for the entomologist to neglect his cabinet and correspondence, 

 even now, in the very heart of the exchanging season, and go out into the woods in
