me show an al. exp. of 22 mm., but the greatest breadth of any fore-wing, which, by 

 itself, measures lO'TZ mm. in length, is only 4 mm., while the smallest expand 

 19 mm., witli a greatest breadth of 3'3 mm. ; the four ? ? in my collection expand 

 18-19 mm. ; (2) the unifoim tone, in all ordinary specimens, of the medium grey 

 ground-colour ; (3) the narrowness of the fasciae, which are also more or less 

 clearly defined. — Eustace R. Bankes, Norden, Corfe Castle : February \Sth, 1907. 



Fupat.ing habits of Jrisfofelia palustrella, Dgl. — In Ent. Mo. Mag., ser. 2, xvii, 

 145 (1906), I stated, with reference to my experience when rearing Aristotelia pa- 

 lustrella, Dgl., that in every instance the cocoon was made, not in the crown of the 

 root where it is said, in Mr. Barrett's note in Ent. Mo. Mag., ser. 2, xv, 278 (1904), 

 to be found as a rule, but in a chamber formed among the young leaves and stems 

 that had sprouted tiierefrom after the shoot had been cut off, and had then died 

 away. For " in every instance " I should have written " in every instance that has 

 come under notice," and the statement, as it stands, requires modification. It 

 correctly embodies the results of the original seai'ch that was made for the cocoons, 

 which were by no means easy to find, but a recent and more thorough one, while 

 clearly establishing the fact that the great majority of larvae, out of about fifteen 

 that spun up, had selected the site I mentioned, revealed the following exceptions. 

 Two cocoons were ensconced in chambers formed inside the thickened bases of stems 

 springing from the rootstocks of the food-plant, while two others were situated in 

 the centres of the basal portions of small shoot-stems. Besides these, a single ex- 

 ample was detected in a chamber hollowed out just beneath the bark of a Rumex 

 stem, at 2^ inches from its base. The material so much utilized by my larvae, when 

 preparing for pupation, would never exist in normal wild plants, and it may well be 

 that their desertion of the rootstocks, when full-fed, was largely due to these having 

 become somewhat dry, and consequently tough for excavation. — Id.: March Wth. 



Occurrence in Britain of the typical form of Aristotelia stipella, Hb. — Mr. 

 Bankes' interesting note (p. fi6, ante) has made me look at my series of this species, 

 as I felt sure that I had bred the typical form commonly here from Atriplex 

 portulacoides. I find that I have six well-marked specimens of the typical stipella, 

 bred in June, 1891, from this plant on the shore of the Fleet Backwater here, and 

 two labelled " bred apparently from Althxa palustris " (but doubtless from Atriplex 

 gathered with it, or from individuals pupating in it) from the Fleet shore at Langton 

 Herring, about three miles off, also in June, 1891. I have also one, slightly less 

 clearly marked, taken here May 27th, 1887, and two of the nseviferella form taken 

 here and at Weymouth in 1889 and 1891, besides some from other localities. 



To the best of my recollection the stipella form was the commonest amongst 

 those which I bred from this neighbourhood. --Nelson M. Eichaedson, Monte-

Hymenoptera Parasitica in, West Suffolk and at Eastbourne. — In continuation 

 of Mr. Saunders' Note (Ent. Mo. Mag., 1907, p. 67), I may say that Lieut.-Col. 

 Nurse has been so good as to send me for determination some very interesting 

 parasitic Hymenoptera from the districts there mentioned. The Ichneumonics;
