Mr. E. P. Pickett exhibited an aberration of the female of 

 Argi/nnis aglaia, aberrations of Epinej^hele jurtina, a series of 

 fresh Jfelannrgia yalathea taken at the end of August, aberra- 

 tions of Zygaena Jilijiendulse and a long aeries of Lycaana corydou 

 taken near Folkestone and Dover in August last, including four 

 males of the last-named species, with the black band on the 

 edge of the fore-wings much deeper than usual ; also twelve 

 dwarf male specimens of this species, four dwarf females, and 

 many other aberrant forms. 



Mr. Goss said that this dwarf form of L. corydon occurred 

 constantly, according to Mr. Sydney Webb, in one valley 

 about two miles east of Dover, but he was unaware of its 

 regular occurrence elsewhere in this country. He remarked 

 that a dwarf form of L. avion occurred in nearly all the 

 localities where the type was found, both in Gloucestershire 

 and Cornwall. Professor Poulton, Dr. Chapman, and Mr. 

 Sloper also remarked on this dwarf form of L. corydon. 



Dr. Chapman exhibited a Jlybocampa sent to him from 

 Queensland by Mr. F. P. Dodd under the name of Notodonta 

 dryinopa, Lower. It was remarkably similar in appearance, 

 structure, and habits to Hyhocamjxi milhattseri (see Euto- 

 mologist, 1889, and p. 43 of 1902). He stated that the pupa 

 with a similar spine to that of //. milhauseri does not cut 

 out a regular oval lid from the cocoon like that species, but by 

 a stabbing process pierces it with a number of holes, so that 

 a piece is more easily pushed off. The cocoon being covered 

 with bits of bark, stone, etc., a cutting process would be im- 

 possible, whereas the cocoon of //. milhauseri was of pure 

 gum-like silk. He pointed out that tlie larva much resembled 

 that of 11. milhauseri, but the hinder segments were more 

 like those of Staiiropus fagi. He also exhibited living eggs, 

 larvae, and imagines of Orina trisfis, var. siiiaragdina, from 

 Pino, Lago Maggiore. The beetles which were still living 

 were taken on May 30th, and had laid many eggs. Dr. 

 Chapman said that the embryo, ready to hatch, might be 

 seen within some of the eggs, and its hatching spines 

 observed. 



Mr. Sloper exhibited a specimen of Lycxna hylas, caught 

 at Dover on the 7th September last.
