16 THE ENTOMOLOGIST. 



too much credit. That name, as I employ it, has been previously 

 used in the same sense by Dallas, Stal, Lethierry and Severin, 

 and Bergroth — the last-named a purist in these matters. But 

 if a name is changed, surely adhesion to the change should be 

 maintained by its advocate. Mr. Kirkaldy recently pointed out, 

 and correctly so, for it was on the authority of Stal, that Zamila, 

 Walk. (1862), must be accepted as a synonym of Pyrilla, Stal 

 (1859). He now, and in this note, uses the name Zamila 

 himself! Some of his other animadversions have been made 

 before and replied to by myself (Ann. Soc. Ent. Belg. li. p. 221), 

 to which he does not refer. I therefore decline to notice them 

 further, and consider such cavilling as outside serious ento- 

 mology. 



NOTES AND OBSERVATIONS. 



Early Stages of American Butterflies Wanted. — I should 

 be greatly obliged if any reader of the ' Entomologist ' would give me 

 information which would enable xne to obtain the ova or pupae of 

 North American butterflies, the food-plants of which are common in 

 this country. — E. E. Bentall ; The Towers, Heybridge, Essex, 

 December 10th, 1907. 



Foe of Dragonfly-nymphs. — Mr. A. O. Eowden, writing from 

 Exeter, on December 16th, 1907, says that the water-boatman {Noto- 

 necta glauca) attacks the nymphs of dragonflies. — • W. J. Lucas ; 

 Kingston-ou-Thames. 



Prevention of Mould in Insects. — Mr. Plum's suggestion 

 (Entom. xl. 290) as to the prevention of mould in relaxing-boxes 

 may possibly prove useful in some cases ; but nothing could well be 

 better than the plan proposed some years ago by my friend Mr. 

 Woodforde, of Market Drayton, viz. a few drops of dilute carbolic 

 acid mixed with the water used to damp the cork (or sand, if used). 

 I have a box at the present time containing several specimens of 

 M. tristata, which I took in Argyllshire early in July. The box has 

 been frequently used since, and the cork repeatedly damped, ])ut not 

 a vestige of mould is perceptible on the specimens of tristata, and if 

 they were worth it, I daresay I could set them to-morrow. — (Eev.) 

 Chas. F. Thornewill. 



Food of the Larva of Acidalia ochrata. — With reference to 

 Mr. Conquest's remarks as to the food of A. ochrata (Entom. xl. 296), 

 I had some young larvae years ago, which fed freely on the flowers of 

 a hawkweed, and I think that they might possibly be reared on dan- 

 delion. My experience with A. strigilata corresponds very closely 

 with Mr. Conquest's. — (Eev.) Chas. F. Thornewill ; Calverhall 

 Vicarage, Whitchurch, Salop, December 6th, 1907. 



Ichneumon Fly opening Cocoon of Bryophila muralis. — Idling 

 away a sunny morning, July 22nd, 1907, at Winscombe, in Somerset,
