Mr. Step exhibited a specimen of Papilio machaon, specially 

 mounted between two pieces of glass for artistic purposes. 

 He had exhibited this specimen in February, igo8, but 

 when looking at it recently he found a living imago of Tinea 

 biselliella enclosed with it. This was remarkable, as the 

 case was perfectly secure, and he had noted no trace of the 

 larva eighteen months ago. The President remarked that 

 this moth takes a long time to develop from the ovum to 

 the imago. Mr. Step also exhibited a number of photo- 

 graphs of entomological and botanical subjects, including 

 one of the rare Deptford pink, Diantlms arincria, from Ash- 

 tead. 



AUGUST 26th, 1909. 



Mr. South exhibited, on behalf of Mr. Esson, of Aberdeen, 

 a noctuid moth taken in that district which appeared to 

 conform to no species known, and was probably new to 

 science. [Since named PetLcephila essoni, Hampson (see 

 "Trans. Entom. Soc. Lond.," 1909, p. 461, pi. xvi).] 



Mr. South also exhibited an imago of Aglais iirticcv, the 

 larva of which had been fed entirely on hop, and produced a 

 normal specimen in every respect. 



Dr. Chapman exhibited a most remarkable aberration of 

 Parasemia plantaginis taken at Ferpecle, Val d' Kerens, 

 Switzerland, on July i8th, 1909. It was rather large, 

 measuring 38 mm. The black markings were reduced to 

 little more than a few faint clouds, so that the moth had 

 pale orange fore-wings and dark orange hind ones, and 

 looked much closer in general aspect to E. grainniica or 

 Diacrisia sanio {N. riissn I a), than to ordinary P. plantaginis. 

 The specimen is now in the British Museum, South Ken- 

 sington. 



Mr. West (Greenwich) exhibited specimens of the homo- 

 pteron, Paraniesns neroosus, a local species taken by him at 

 Gravesend among rushes. 



Mr. Newman exhibited nearly full-fed larvae of Eupithccia 

 extensaria which had been reared from ova on southern- 

 wood {Artemisia abrotamun). 



He also showed a larva of Staiwopus fagi, and pointed out 

 the great resemblance between its obliquely furrowed brown 

 body and the obliquely wrinkled dead leaf of beech. 



Mr. F. Noad Clark exhibited a cluster of one of the bird's- 

 nest fungi {Cyathus striatns), found in an old garden, appa- 

 rently attached to rotting wooden bordering.
