communities (which were contained in glass tubes) consisted 
of a few individuals of the immature sexual forms and of a 
neoteinic queen : this latter had increased somewhat in size 
during the eight months it had been in Dr. Haviland's 
possession, but no eggs had been deposited, neither had any 
of the immature individuals developed into winged forms. 
The second community exhibited consisted entirely of the 
immature sexual forms, and this community had produced 
numerous winged adults while it had been in Dr. Haviland's 
possession. Specimens were also exhibited to illustrate the 
neoteinic forms that were produced in Borneo after a 
community had been artificially orphaned. As regards these, 
Dr. Sharp expressed the hope that Dr. Haviland would 
shortly publish the very valuable observations he had made. 
In the case of a species of fungus Termite, Dr. Haviland had 
found that the community had replaced a king and queen 
by normal, not by neoteinic forms. 
Professor Eiley remarked that in many cases it would be 
extremely difficult to artificially orphan a nest without de- 
stroying it ; he also commented on -the short time in which 
the queen appeared to have been developed, and on the ap- 
parently rapid development of the wing pads, which usually 
cannot take place except after several moults ; and he 
expressed his opinion that further information on these 
points was much to be desired : he corroborated the observa- 
tion of Dr. Haviland with regard to the great variability in 
the nests of different years (or even of the same year) of the 
number of queens, true or neoteinic ; in one nest of Euterme^ 
morio he found one-fourth of the inhabitants to be true kings 
and queens, although not fully developed. 
Mr. McLachlan exhibited examples of the female of Pyrrho- 
soma minium, Harris, having the abdomen incrusted with 
whitish mud through ovipositing in a ditch in which the 
water was nearly all dried up. He had noticed the same 
thing in other species of Agrionidae. 
Herr Jacoby exhibited four varieties of Smerinthus tilicB. 
Mr. Enock exhibited specimens of the thistle-gall fly, 
Trypeta cardui, and also of Caraphr actus cinctus, Haliday 
( = Polynema natansy Lubbock) : with regard to the latter
