State that ‘moths, bees, &c.” are captured by the 
flowers of the arauja [phystanthus| and may live in 
this captivity for two or more days, the effect of the 
plant being merely mechanical detention.

Fertilization of corydalis 
(Nature, 7 May 1874, v. 10, 
Hart, W. E.

Believes the flower slightly proterogynous, and shows 
how it might be fertilized by insects —which he has not 
seen at work. W: Z.- (2421) 
Hart, W. E. Fertilization of vzola tricolor 
and wv. cornuta. (Nature, 24 July 1873, v. 
8, p- 244-245, 16 cm.) 
Believes the flo.vers of vfola trico/or adapted to cross- 
fertilization by larger insects than thrips. Has seen 
them visited py bombus and preris rapae. V. cornuta 
is adapted to fertilization by xoctuidae, though the 
flowers are also visited by bees, flies, and buttertlies, in 
the daytime. W: T. (2422)

Describes the structure of the flowers of v/ola tricolor, 
and states that they are visited by bombus muscorum; 
corrects a Statement in T. H. Farrer’s ‘‘On the fertili- 
zation of a few common papilionaceous flowers” (Na- 
ture, 17 Oct. 1872, v. 6, p. 499) [Rec., 2297], as to the

Has often watched flies belonging or allied to the syr- 
phidae, while eating pollen of various flowers, “which 
they effected by a quick jerking and grinding movement 
of the mandibulae.” W: T. (2424) 
Hart, W. E. Pollen eaters. (Nature, 30 
Jat. 1893,:¥-.7,) Px 242,.6.6me) 
Believes that syrphidae in gathering pollen from ¢a- 
raxacum and other compositae may ettect fertilization, 
but believes their visits injurious to some other flowers. 
Inquires if his former use of the word ‘‘mandibulae” 
(op. cit., p. 161) is correct. W: T. (2425)

Notes the self fertilization of geranium robertianum 
in November. Believes, however, that insect fertiliza- 
tion of certain flowers may occur in winter.
