and fom- females, the latter appearing considerably after the others. He remarked 
also that, in allied insects, the number of males was generally in excess of the 
females. 
Prof. Westwood said that he had recently seen a nest of a bee formed 
. in the toes of a Mexican drinking vessel, formed in the shape of an imaginary 
quadruped. 
Mr. McLachlan remarked that he had recently found a considerable number 
of the males of the saw-fly Strongylog aster cingulatus. The females of this species 
were universally abundant on the joung fern-tops, but the male was rarely met 
with. He alluded also to the apparent absence of males in many Tentliredinidm ; 
e. g., — Selandria stramineipes, the females of which are very common. 
Mr. Smith said that, during many years, he had only once found the males of 
the Strongylogaster. 
Mr. Stevens exhibited a Gordius which swarmed in his garden that morning 
after the heavy rain of the preceding night. He had been told that at the same 
time it was very abundant in Kent, twisting itself round the foliage of rose-trees ; 
and Mr. Weir stated that he had been informed of a similar occurrence having been 
observed in another part of the country.* 
The President exhibited a minute apterous Dipteron which he had found 
under bark in his grounds at Farnborough ; he thought it was the Epidcvpus 
veriaticus of Walker's work. Professor Westwood thought it might be identical 
with a species figured by De Geer. 
Prof. Westwood enquired if any Member had observed any constant difference 
of colour in the larvse of the sexes of Lepidoptera. Authentic information on this 
point is very desirable.

• At the Linnean Society, on the 6th June, living examples of this were exhibited which had been 
fouud at Epsom under similar circumstances, and it was mentioned that it bad occurred at many other 
places. Dr. Cobbold said it was the common Gordius aquaticus, and had apparently emerged frora 
the ground in unusual numbers, owing to the heavy I'ain-fall.
