to rest (?) in, and under what conditions it is chosen ? — 

 G. B. CorbiJi. 



[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 Netvman.] 



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 grovi's 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 Cecidorayia, 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 Tiliariura, which 1 have before 

 spoken of, and the little white Acarus, which transfers to itself 

 the hollow remnants of the Aphides, whose contents 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.

 of London, November 17 to December I, 1873. 



Deilephila Euphorbias and Sphinx Pinaslri at Harwich. 

 — Mr. Higgins exhibited two bred specimens of Deilephila 

 Euphorbias (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. — Mr. Champion 

 exhibited a bred specimen of Pachnobia alpina from Braemar; 

 also Harpalus quadripunctatus from Braemar; Anisotoma
