had bred several from larve taken near Winchester. They 
were bred with others of the ordinary colour; but he believed 
that the variety was natural, and not caused by extraneous 
circumstances. 
New Coleoptera.—Mr. G. C. Champion exhibited speci- 
mens of Anisotoma oblonga, H7., taken by him near Farnham, 
and A. curta, Fairm., from Esher, Surrey. The latter was 
new to the British list. Also A. Algirica, a new species, 
taken by Mr. Rippon in Algiers. 
Larve and Pupe of Ephydra.— My. William Cole exhibited 
carefully-executed drawings of the pupz of a species, appa- 
rently. belonging to the Dipterous genus Ephydra, which he 
had taken clinging to the stems of grass below high-water 
mark, near Southend. The water whence it was taken was 
brackish. He also exhibited the larve and perfect insects in 
spirits. 
Parasites of Osmia.—The President stated, with reference 
to the numerous parasites found on Osmia tridentata, that 
M. Jules Lichtenstein, of Montpellier, had recently obtained 
the Zonitis preusta from the cells of this bee; and likewise 
the Eucheelius vetusta, Duf, from its desiccated adult larve, 
in the same way that Halticella Osmicida effects its meta- 
morphosis; thus making the thirteenth parasite recorded as 
affecting this Osmia.

GENTLEMEN,—The Doubleday Collection of Lepidoptera, 
recently placed in the Bethnal Green Museum, is a collection 
of very great value to all entomologists, containing as it does 
types of nearly all the British and European species; and it 
is very essential that it should be open for al] students to be 
able to compare and name specimens therefrom. This 
Collection, being arranged according to the universally 
accepted catalogue of our species, it is, therefore, of the 
greatest value. During the lifetime of the late Mr. Doubleday, 
the Collection was always open to any entomologist who 
wished to inspect it; and we beg permission to have the
