extended against the upper plate of glass. ‘The vertical threads are 
arranged in pairs and pass right and left of the bodies of the butterflies; 
the horizontal threads are single and separate the horizontal rows; in 
addition, between the various specimens each horizontal thread is fixed 
to the glass by a small label of paper which serves to number the 
examples, and in this way all derangement is prevented in a vertical 
direction, the horizontal thread strongly holding the vertical thread 
against the glass.” 
This plan is claimed to be a great economy in space and expense. 
The glass frames can be arranged on the shelves of a bookcase. The 
collection takes up a minimum of space. There is absolute security 
against mites. Comparisons can be made so much easier. The two 
surfaces of the wings can be seen with equal facility. The wings can 
be viewed on a changeable ground. ‘The pin is never in the way of a 
lens for close examination. All specimens are in exactly similar 
positions for comparisons. All labels can be placed close to the insect. 
Dr. Verity concludes by giving further details of the arrangement and 
methods for converting collections already made.—H.J.T.

The 23rd Annual Congress of the South-Eastern Union of Scientific 
Societies will be held in London, under the Presidency of Sir Daniel 
Morris, K.C.M.G., ete., from Wednesday to Saturday, May 29th to 
June Ist, 1918. We understand that the Headquarters will be as last 
year, the rooms of the Linnean Society at Burlington House, Picéa- 
dilly, which have been again kindly lent to the Union. On Thursday 
evening, May 80th, Lieut.-Col. Sir Ronald Ross, R.A.M.C., K.C.B., 
etc., will open a discussion on the subject of mosquitoes in England. 
Members of affiliated Societies are admitted to the Congress on pay- 
ment of 3s., and will receive a copy of the annual volume of the South- 
Eastern Naturalist. The Programme of the arrangements, list of 
papers to be read, and exeursions, will be ready shortly. 
In the Bull. Soc. ent. Fr. for October last are several interesting 
and useful notes and articles. M. du Buysson gives particulars of the 
parasitisation of the nymphs of Coccinella septempunctata, met with on 
leaves of the vine, by the Dipteron Phora fasciata. M. Peyerimhoff 
demonstrates in a long series of observations that the Chironomids 
Ceratopogon species not only attack mammals, including man, but also 
insects and their larvee, e.g., species of Culew (Dip.), Cidaria didymata, 
Hrinnys ello (Sphingid) larva, and Meloé (Col.). M. Demaison con- 
tributes notes on the various forms of Parasemia plantaginis, viz., var. 
laemmermanni, var. caucasica, ab. flava, race floccosa, race altaica, race. 
sifanica, var. insularum, var. hatipennis, ab. hospita, and the British © 
race. Dr. Roger Verity gives observations on certain speciés of Zygaena, 
which Mr. Bethune-Baker is dealing with on another page of this 
magazine. In addition there are numerous new species described 
in various other orders, and some biological notes of importance.
