of which appeared to him to agree with Prof. Riley’s descrip- 
tion of Merisus destructor given in his pamphlet on ‘The 
Parasites of the Hessian Fly.’ Mr. Enock said his opinion was 
further strengthened by that of Dr. Lindeman, who identified 
some Russian species from examples sent to him by Miss EK. A. 
Ormerod. Mr. Enock further stated that during May and June 
he had bred a very large number of various parasites from 
puparia; amongst them were about a hundred specimens of 
the one which he was inclined to think was Merisus destructor, 
specimens of which he sent (alive) to Dr. Lindeman, who, in 
his reply, states that ‘‘ The specimens of parasites sent, bred in 
England from the Hessian Fly, seem to me to be Merisus 
destructor of Riley; they differ from my M. intermedius by the 
more compressed and broader shape of the body in the female, 
by their less intense green lustre, and by the brown or almost 
black antenne.’’ Mr. Enock also said that he had bred 
several specimens of another parasite, which he is inclined to 
think will prove to be identical with Platygaster herrickit of 
Riley, and, should this be correct, it suggests that some of 
the attacks of Hessian Fly may have come from America. 
Mr. Wallis-Kew exhibited a number of larve of Adimonia 
tanaceti (Fab.), found in Lincolnshire, feeding on Seabious. 
Mr. Porritt exhibited a number of variable specimens of 
Arctia mendica, bred from a batch of eggs found last year on a 
species of Iwnex at Huddersfield. Mr. Porritt said that this 
species, in the neighbourhood of Huddersfield, was often more 
spotted than the typical form, but he had never before seen 
anything approaching in extent the variation exhibited in 
these bred specimens. Out of forty-four specimens (twenty- 
five males and nineteen females) not more than eight were 
like the ordinary type of the species. 
Mr. M‘Lachlan exhibited specimens of Palingenia longicauda 
(in alcohol) from Holland—the largest of the European Ephe- 
merida (May-flies), and at the same time one of the most local. 
Mr. Jacoby exhibited the following species of Phytophagous 
Coleoptera from Africa and Madagascar, recently described by 
him in the ‘Transactions’ of the Society, viz. :—Lema lati- 
collis, Cladocera nigripennis, Oedionychis madagascariensis, Ble- 
pharida intermedia, B. nigromaculata, Chrysomela madagascart-
