PSYLLIDAJ. 
Frauenfeld (Verb, zool.-bot. Ges. in Wien^xvi. pp. 977-980) remarks upon 
tbe difficulties attending tbe determination of tbe species of Psylla, for wbicb 
be considers tbe study of tbe early stages, and indeed of tbe natural bistory 
of tbe animals, will furnish tbe best data. He describes several PsyllidcBj 
wbicb be bas been unable to determine by means of Forster’s paper, but does 
not name them. They live on tbe following plants : — Sorhus aria, Knautia 
sylvatica, Leontodon hastile, Berheris vulgaris, Urtica dioica, Senecio nemorensis, 
and Cirsium erysithales. 
APHIDIDiE. 
Lubbock notices Balbiani’s observations. Proc. Ent. Soc, 1866, p. xx. 
Westwood remarks on tbe occurrence of wingless Aphides on tbe yoxmg 
sboots of isolated rose-trees. Proc. Ent. Soc. 1866, pp. xx-xxi. E. Shep- 
pard bad noticed a similar occurrence on tbe jasmine. 
F. Smith notices galls formed by Aphides on the shoots of the elm, and 
found by him at Deal. The galls are of considerable size, hollow, green, with 
tbe sunny side reddened. Proc. Ent. Soc. 1866, p. xxxii. MacLacblan and 
Lubbock had met with tbe same gall on elms at Kingston-on-Thames and at 
Naples, ibid. 
MacLachlan refers to tbe production of large leaf-galls on tbe elm, which 
he ascribes to Aphis gallarum-uhni (De Geer). Ent. M. Mag. iii. pp. 157-169. 
(According to Kaltenbacb these galls are produced by Schizoncura lanuginosa, 
Hart.). 
G RUBE reports ( J abrosbor. scbles. G os. vaterl. Cult. 1866, pp. 42-46) on swarms 
of Aphides observed in Breslau on tbe 12tb & 13tb October 1866, and re- 
garded by many as precursors of the cholera. Tbe species appears to ap- 
proach most closely to Aphis convolvuli (Kalt.). When examined on tbe sup- 
position that these swarms would consist of tbe perfectly sexual individuals 
destined to furnish a progeny of eggs, it was found that this was not tbe case, 
all tbe specimens dissected being viviparous forms, with from 4 to 8 more or 
less developed embryos. No males were found. The swarms continued to 
appear until the beginning of November ; but about the 30th October winged 
males and wingless females occurred paired in the swarms, but still intermixed 
with viviparous individuals. 
AlEURODIDvE. 
Frauenfeld bas received from Mexico specimens of an Aleurodes wbicb 
attacks and injures tbe leaves of Viburnum tinus. Verb, zool.-bot. Ges. in

Porphyrophora radicum graminum (Barensp.) is noticed as injurious to 
wheat by F. Low, Verb, zool.-bot. Ges. in Wien, xvi. p. 946.

where they live on tbe leaves of Bucalyptus, Proc. Ent. Soc. 1866, p. xxxii.
