NOTES AND OBSERVATIONS. 



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

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

 poplar [Popnlm) in June near the village of Rottingdeaii, Sussex. I 

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

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

 the food-plants of the larva of A. iria, but in worlis on British Lepido- 

 ptera sallow alone is given. — Ed.] 



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

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

 Orthetnitn cancdlatum. plentiful in the Norfolk Broads in 1903. He 

 further reminds me that he found J^l^clma ini.rta 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 Clueroeampa esou this season, I collected about fifty larvfe 

 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. 2nd she showed me several of these silkworms turning blaclv. 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 waj^ keeping 

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

 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, but 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;

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

 a small species of Tenthredinidae from New Zealand, which appears
