NOVEMBER gth, 1905. 



The President in the Chair. 



Mr. Stonell exhibited various aberrations of Lepidoptera, 

 among which was a specimen of Callimorpha dominula with 

 yellowish wings. 



Mr. H. Moore exhibited a collection of South African 

 Orthoptera, including examples of the following genera and 

 species : Sibylla pretiosa, Stal. ; Popa undata, Fabr. ; Br achy - 

 trypes mcmbranaceus, Drury ; Gryllus ignobilis ; Enyaliopsis 

 petersii, Schaum, from Unyoro ; Mustius orientalis ; Cymato- 

 mera denticollis ; Conocephalus nitidulus ; C. mandibular is ; 

 Zonocerus elegans, Thunb. ; Z . roscipennis ; Z. sanguinolcnta ; 

 Phymateus morbillosns, Linn. ; Xiphocera, sp. ? ; Cyrtacanthacris 

 scptcmfasciata, Serville ; and C . purpurifera, Walker. 



Messrs. Main and Harrison exhibited a short series of 

 Acidalia aversata, bred from a female taken near Bude, Corn- 

 wall. The parent was of the reddish-clay-coloured form, 

 and banded. The moths bred are eleven in number, of 

 which six resemble the parent, and five are of the ordinary 

 putty-coloured form, four without a band, and one with a 

 dark band. 



Mr. Robt. Adkin exhibited a specimen of Pararge egeria 

 taken at Shaldon, South Devon, on September 21st last, in 

 which the usual pale rings around the ocelli of the hind- 

 wings were almost absent, being indicated only by a few pale 

 scales ; the ground colour of the insect was also consider- 

 ably darker, and the usual pale spots somewhat less promi- 

 nent than in the forms generally met with, and it appeared to 

 be intermediate between the accepted type and a variety 

 taken by Major Still in the neighbourhood of Dartmoor in 

 August, 1892, and which is figured in Barrett's " Lepidoptera 

 of the British Isles," vol. i, pi. xxxi. Other examples taken 

 at the same time and place, as well as from the New Forest, 

 were shown for comparison. 



Mr. Adkin also exhibited a series of Dryobota {Hadena)
