94 THE ENTOMOLOGIST. 
this species extends to Britain, and, secondly, as positively 
connecting the gall with the gall-maker; probably, however, 
the name of A. Corticis, which has the claim of priority, will 
supersede that of A. Sieboldii. The species appear to be 
identical— Edward Newman. | 
Rose-galls—I have by me an American rose-gall, of which 
the English rose-gall, about to be mentioned, is a little repre- 
sentative. The latter is inhabited by Rhodites Rosarum of 
Giraud, and, like the former, which nourishes Rhodites bicolor 
of Harris, is distinguished by its elegance, and it has gene- 
rally the shape of a little spine-set ball, and its spines are red 
like the spines of the briar, and sometimes it has not a pea- 
shape, but is merely a swelling of the basal part of the spine. 
In this state it is with other spines, but in its round form it 
occurs on the surface or on the edge of a leaf, and is only 
indicative of the spines, which, like other spines and thorns, 
are said to be merely rolled-up leaves. With this gall there 
is another little one without spines; it is made by Rhodites 
Eglanteriz of Hartig, and much resembles the Rosa spino- 
sissima gall, in which Rhodites spinosissime of Giraud is 
reared; but more may be said on this matter in a future 
note on rose-galls.— Francis Walker. 
Correction of an Error.—I1 am sorry I have to con- 
tradict my notice of the capture of Plusia Interrogationis 
(Entom. vii. 23). It proved to be P. Pulchrina, a species I 
had never seen. Mr. N. F. Dobrée, upon seeing it, instantly 
discovered my mistake; and I should not like knowingly to 
add one to the long lists of “rarities,” whose history is, to 
say the least of it, doubtful—Geo. R. Dawson; Pounds- 
worth, Driffield, March 20, 1874.

Photographs of Insects taken with Camera Obscura.— 
Mr. Mendola exhibited some photographs of minute insects 
taken with the camera obscura and microscope. 
A Bombyx with Aquatic Larva.—Mr. M‘Lachlan valled 
attention to a paper in the last part of the ‘Annales de la 
Sociéte Entomologique de France,’ by M. Bar and Dr. 
Laboulbéne, on a species of a Bombycide closely related to 
the tiger-moths described and figured by M. Bar as Palustra
