122 THE ENTOMOLOGIST. 



So far as I am awave, in uo one locality in the immediate North of 

 London are so many dragonflies to be met with as in Wanstead Park 

 — twelve kinds : — 



JhlschnidcB. — ^schna cyanea, jE. grandis. 



LibellulidcB. — LiheUuJa depressa, L. quadrimaculata, Synipetruin 

 vuhjatum. 



Agrionid(c. — Agrion pulchellum, A. puella, A. clegans, A. cyathigenim 

 (probably all these number of individuals most abundant on flags 

 and water-lily leaves), Lestes sponsa, Erythromma najas, Pyrrhosovia 

 minium. Erythromma najas is very pugnacious, and chases away any 

 other dragonfly that settles on the same water-lily leaf as itself. —

Parasites of Bombyx rubi, &c. {ante, p. 69). — Mr. Arkle has sent 

 me specimens of Apanteles dijficilis, Nees. Doubtless the parasite of 

 Arctia caia was the closely allied Apanteles cairn, Bouche. Mr. Arkle 

 has also kindly sent me one of the cocoons of the heather-feeding 

 sawfly, which I hope to breed. I find no sawfly with this food-plant 

 in Cameron, Andre, Brischke, or Kaltenbach ; the cocoon greatly 

 resembles that of one of the Ophionid^e, being almost exactly like that 

 of Ophion luteum or Paniscus cephalotes. — Edward A. Fitch ; Maldou. 



The Diamond Jubilee. — It has been suggested to us that the 

 lepidopterists of the British Islands should commemorate Her 

 Majesty's long reign by forming a thoroughly representative collection 

 of the butterflies and moths found in the United Kingdom, and 

 presenting the same to the Natural History Museum at South Ken- 

 sington. Possibly such a scheme may be considered too large an 

 affair to undertake ; there is no reason, however, why an attempt 

 should not be made to extend and improve the existing collection 

 of British Lepidoptera in the Museum, which is certainly not as com- 

 plete as it should be. If a committee were formed to work out the 

 initial details, there is no doubt that any appeals for assistance in the 

 shape of specimens would be liberally responded to. We shall be 

 very pleased to have the views of our readers upon this subject. 



CAPTURES AND FIELD REPORTS. 



AcHERONTiA ATROPOs AT Tenbury. — I was the recipient of a very fine 

 pupa of A. alropos, sent me on Feb. 18th, by a lady residing in Tenbury. 

 From her letter I understand that the perfect insect paid her beehives 

 several visits in July and August, and in October three pupse were 

 unearthed in her garden. I liave since followed the instructions for forcing 

 given by Mr. G. F. Mathew (Entom. xxix. 328), the results of which I 

 eagerly await. — H. W. Bell-Marley ; Ravenscourt Park, London. 



AcHERONTiA ATROPOS IN SaFFOLK. — I have not noticed amongst the 

 many records of the capture of this insect in 1890 any from Suffolk, and 

 I might say, though somewhat late, that two were taken in Ipswich ; one 

 was in the pubHc park. A friend who showed me the specimen mistook it 

 for a piece of bark Ofi the grass, and was about to give it a sharp blow with
