APRIL i&th, 1898. 

 Mr. R. Adkin, F.E.S., Vice-Pyesident, in the Chair. 



Mr. Bishop exhibited a bred series of Tceniocampa niiniosa, 

 some being very fine and bright in coloration, while others 

 were dark. He remarked that many of the specimens he 

 had bred had the claws of the front legs undeveloped, and 

 were thus prevented from hanging on vertical surfaces. Mr. 

 McArthur said that he had frequently met with similar 

 imperfectly developed specimens. 



Mr. Lucas exhibited flowers of the snake's-head (Friiillaria 

 meleagris) from the fields near the banks of the Thames at 

 Oxford. Mr. Tunale}' said that he had recently had a bunch 

 of the flowers sent to him from Pinner. 



Mr. Sauze exhibited a series of Brachinus crepitans from 

 Swanage. This Coleopteron ejects a caustic volatile liquid 

 from its abdomen when pursued. It is a very variable insect 

 both as to size and colour, 



Mr. Edward Saunders sent for exhibition a series of 

 Hemiptera Heteroptera, comprising examples of all the 

 families and most of the genera of this order. 



Mr. West exhibited a case of Hemiptera, comprising a 

 large number of species taken by himself during the last 

 three years. 



Mr. Robert Adkin exhibited a series of Eugonia quercinaria, 

 including males, females, and a gynandromorphous specimen, 

 together with mounted specimens of the genitalia and photo- 

 graphs of the same enlarged 30 diameters, and read the 

 following note J 



"On the occasion of the Society's Field Meeting at Chalfont 

 Road on July 23rd, i8g6, Eugonia quercinaria was found 

 somewhat commonly hanging from dry grass stems in the 

 woods {Proc, 1896, p. 107). From one of the females so 

 taken I procured a small batch of eggs, which in due time 

 hatched, and from them I bred the series now exhibited. 

 The imagines commenced to emerge on June 30th, and the 

 last came forth on July loth, 1897. Some thirty-three in 

 all emerged, the sexes being as nearly as possible equally 

 divided ; two of them were so badly crippled as to be beyond 

 recognition, and one, although imperfectly developed, was so 

 peculiar in its appearance that, although not quite perfect, I 

 set it. This specimen emerged, or, to be correct, attempted 

 to emerge, on July 5th; the head and appendages, legs, 

 wings, and thorax were fully developed, but it had failed 

 to free its abdomen from the pupa skin. Perhaps it was
