Nematus vesicator , Bremi, = helicinus, Brischke. — I have bred 

 this gall-maker from a large bladder-like gall of a green colour, wbicli 

 I found on a willow in Rannocb, during a visit of one day's duration 

 whicli I made to that place last year, in order to procure some other 

 insects. My specimens show considerable variation in the coloration 

 of the abdomen, one example having it nearly all luteous, while in 

 other specimens the belly only is of that colour, the rest being black. 

 It has no relation, I believe, with the N. helicinus, Thoms. 



Nematus Westermanni, Thomson, Opusc. Ent., 615, 3 ; Hymen. 

 Scand., i, 87. — I captured four specimens (three $ one ^J) of what 

 I take to be this species, last June, among osiers on the banks of 

 the Severn below Grloucester. It is very like the above variable 

 species, but is, I think, distinct from it. 



Gryptocampus angustus, Inchbald (nee Htg.), Ent. Mo. Mag., i, 

 47; G. mucronatus, Vollenhoven (wee Htg.), Tijds. Ent. (2) vi, pi. 12 

 = G. pentandrce, Retz. — I have taken pentandrce in various parts of 

 Scotland. It seems, however, to be local, and in some years is far 

 more abundant than in others. I have seen several small willows with 

 their twigs very much distorted by the galls, so numerous were they. 

 Last spi'ing I noticed, among a number of galls collected on the 

 Kilpatrick Hills, a curious instance of how one animal can appropriate 

 to its own use the work of another. Erom the galls I speak of, a good 

 many of the flies had emerged (this was in March), and the empty 

 cocoons had been utilized by a spider, which had filled them com- 

 pletely with her eggs, there being none, so far as I could see, in any 

 other part of the gall. I am sure I counted upwards of a hundred 

 cocoons filled with eggs ; sometimes there would be several cocoons in 

 a gall containing them, while in others there would be only one ; and 

 in every case I could not help admiring the neat way in which the 

 eggs were packed in the cocoons. A few of the cocoons were also 

 tenanted by a black species of Aphis, and from it I bred a couple of 

 AUolria minuta, Htg.
