Exhibitions, &e. 
Mr. Stevens exhibited specimens of Tillus unifasciatus and Xylotrogus 
brunneus, taken on an oak fence at Upper Norwood. These insects did not 
appear to have been taken near London for many years. 
Mr. Forbes exhibited a specimen of Quedius dilatatus (a parasite in 
hornets’ nests), taken by him at sugar in the New Forest. 
Mr. Champion exhibited Harpalus 4-punctatus, Dendrophagus crenatus, 
Leptura sanguinolenta (female), Amara alpina (female), Cryptophagus 
parallelus aud Omosita depressa, all taken at Aviemore, in Inverness- 
shire. 
A letter was read from T. V. Lister, Esq., of the Foreign Office, trans- 
mitting, for the information of the Entomological Society, a copy of a 
despatch from Sir John Walsham, Her Majesty’s Chargé d’Affaires at 
Madrid, relative to the plague of locusts, together with a box containing speci- 
mens of the insect, and a number of earthen egg-cases, each containing from 
thirty to forty eggs. The despatch stated that the Official Report showing 
the progress of the plague and the steps taken to exterminate the insect had 
not yet been published, but a copy would be sent to the Society in a few 
weeks. It was said that the damage done by the locusts this year was 
considerably less than that of last year, owing to the number of soldiers 
which the Government had been enabled to employ since the war was over 
to assist the inhabitants of the districts where the plague existed in 
destroying the insects. The insects sent were stated to be specimens of 
Locusta migratoria, but on examivation they were ascertained to be the 
Locusta albifrons, Fab. (Decticus albifrons, Savigny). 
Mr. M‘Lachlan exhibited a series of thirteen examples of a dragonfly 
(Diplax meridionalis, Selys), recently taken by him in the Alpes Dauphiné 
_ of France, between Grenoble and Briangon (the exact locality being near
