to rest (?) in, and under what conditions it is chosen ?— 
G. B. Corbin. 
[This habit is very familiar to Hymenopterists; I have 
observed it in several species of Nomada, and also in Chelo- 
stoma florisomne. ‘These observations have been frequently 
recorded, and have been styled “roosting by the mandibular 
process.” — Edward Newman.] 
Lime-galls.—In the ‘ Fifth Annual Report on Insects of 
the State of Missouri,’ by C. V. Riley, there is a figure 
(p. 119) of a gall that grows on the vine-leaf, and the author 
remarks that similar, but distinct, galls grow on the leaves of 
hickory and hackberry. Each of these vine-galls contains a 
pale orange larva, made by a Cecidomyia, which has not yet 
been described. These galls exactly resemble the excrescences 
which may be seen here and there on lime-leaves in England, 
but no insects have been found in these excrescences, except 
an Acarus, as was mentioned in a French publication, which 
I cited many years ago in a notice on these formations. It is 
uncertain whether this Acarus, or mite, is identical with one 
or other of two kinds of mites which often occur under lime- 
leaves,— the green Tetranychus Tiliarium, which | have before 
spoken of, and the little white Acarus, which transfers to itself 
the hollow remnants of the Aphides, whose conteuts have been 
already appropriated by Aphidii. The round red gall on the 
twigs of the lime is of more frequent occurrence than the 
lanceolate formation before mentioned, and is inhabited by 
the grub of Sciara tilicola, which leaves them and enters the 
earth, and there assumes the imago state.— Francis Walker. 
Extracts from the Proceedings of the Entomological Society 
of London, November 17 to December 1, 1873. 
Deilephila Euphorbie and Sphinx Pinaslri at Harwich. 
—Mr. Higgins exhibited two bred specimens of Deilephila 
Euphorbiz (one a remarkable variety), and a Sphinx Pinastri, 
taken near Harwich in June, 1872, when several specimens 
of the former were found in the larva state. 
Pachnobia alpina from Braemar, §c.—Myr. Champion 
exhibited a bred specimen of Pachnobia alpina from Braemar ; 
also Harpalus quadripunctatus from Braemar; Anisotoma
