NOTES AND OBSERVATIONS. 



Larva of Apatura iris on Poplar. — In looking through my notes 

 for 1903, I find that a full-grown larva of Apatura iris was taken on a 

 poplar (Pojndus) in June near the village of Rottingdeau, Sussex. I 

 hope this note may be of interest to the readers of your paper. — 

 J. A. Croft; Charterhouse, Godalming, Feb. 11th, 1904. 



[Nearly all continental authors mention poplar as well as sallow as 

 the food-plants of the larva of A. iris, but in works on British Lepido- 

 ptera sallow alone is given. — Ed.] 



Dragonflies in 1902 and 1903. — In connection with my paper on 

 this subject {ante, p. 29), Mr. G. T. Porritt tells me that he found 

 Orthetnim cancellatum plentiful in the Norfolk Broads in 1903. He 

 further reminds me that he found /Eschna mixta very common in 

 S. Devon in 1902, and that it then occurred over a wider area than 

 that in which he had found it previously. — W. J. Luoas. 



Dipterous Parasite attacking Silkworm Larv^. — Wishing to 

 breed a few C/uerocampa eson this season, I collected about fifty larv£e 

 of the species. Over thirty of these were badly " ichneumoned " ; this, 

 however, was not apparent until they reached the pupa state. From 

 these thirty there must have been over two hundred dipterous flies, 

 and many remained in the room, on the windows, &c. My wife was 

 rearing a large number of silkworms in the same apartment. On 

 Dec. 2ud she showed me several of these silkworms turning black, and in 

 many places swollen. I opened some, and found them full of maggots. 

 I killed over fifty of the worms that were attacked in this way, keeping 

 three or four. They never spun up, but two managed to turn to pupaB, 

 and I have since bred several of the same parasitic flies that emerged 

 from the C^. eson. One, however, was so full of the grubs that, before 

 it finally burst, fifteen large maggots emerged. Thinking this was 

 something unusual, I have written these few notes. In any case the 

 fly must have made a mistake, as besides the one that burst as men- 

 tioned, I am sure many that I killed were too full of the grubs for the 

 latter to be able to feed up in their host. From the two that pupated 

 without spinning, only eleven flies resulted. I conclude the silkworm 

 is "ichneumoned " in the natural state, bat this is the first time I have 

 ever seen any, or heard of any, being attacked when kept in confine- 

 ment, and my wife has been rearing silkworms for years. I may 

 mention that the silkworm is double-brooded here. — G. F. Leigh; 

 Durban, Natal. 



Note on a Sawfly from New Zealand. — Some years ago I described 

 a small species of Tenthredinida from New Zealand, which appears
