A Monsieur le Secretaire de la Societe 
Entomologique de Londres. 
Exhibitions, etc, 
Mr. R. Adkin exhibited a specimen of Mesogona acetosella, 
taken at Arlington, Sussex, in October, 1895. It was stated 
that this was the first recorded capture of this species in 
Britain. 
Mr. G. T. Porritt exhibited an example of Halesm guttati- 
pennis, taken at Lye, Worcestershire, in November, 1889. It 
was believed to be the third British example. Mr. Porritt 
also exhibited a series of Mania typica, showing a curious 
malformation in all the specimens. He stated that about 
one-third of a large brood had emerged in exactly the same 
form, having the wings only half developed, but with the 
markings clearly defined. Mr. Tutt and Mr. McLachlan 
referred respectively to similar malformations in Agrotis 
tritici and Hadena chenopodii. 
Mr. Goss read a communication from Mr. Sidney Crompton, 
of Salamanca, Tenerife, announcing the capture there by 
Mr. Hammerton of two specimens of Diadema misippus, a 
species of butterfly not previously recorded from Tenerife. 
Mr. Crompton said the specimens were in such fine condition 
that they must have been introduced into Tenerife in the 
larval or pupal state and emerged there. Mr. Hampson, 
Prof. Meldola, and Mr. Osbert Salvin made some remarks 
on the distribution of the species. 
Papers, etc., read. 
Mr. Champion read a paper entitled, On the Heteromerous 
Coleoptera of St. Vincent, Grenada, and the Grenadines." 
Mr. Kenneth J. Morton communicated a paper entitled, 
" New or Little Known Palgearctic Perlidae."
