 Aleiicis pictaria had been out a fortnight, and that Pieris rajKe had 

 been seen. 



APRIL 27th, 1911. 



Mr. P. A. Buxton, of Tonbridge, was elected a member. 



Mr. Tonge exhibited a portion of a stem of Vihtirmun lantana 

 with the pupa case of ^■Eijeria andiencFforpiis in sitii as left by the 

 imago at emergence. He had found four such cases recently. 



The President exhibited a similar stem with the pupa case 

 projecting from the larval burrow and the living imago which ha(J 

 emerged in confinement. 



Mr. Kaye also exhibited a fine plant of the Orchid Cattleya 

 citrina in flower, and stated that it was a native of Mexico, and 

 grew at a much greater elevation than most species of the genus. 

 It was also an aberrant species in the form of its flower. 



Mr. E. Adkin exhibited a remarkable gynandrous specimen of 

 Laniocanipa (Boiiibij.r) qiiercus in which the left antenna and wings 

 followed the male characters and the right those of the female, but 

 were of the male coloration. The specimen was reared from a 

 Yorkshire larva some years ago, and had since been in the posses- 

 sion of Mr. Sam J. Capper, of Liverpool. 



Mr. Newman exhibited a larva of CalUuiorpha dnuiinula, in 

 which the usual yellow markings were almost entirely wanting. 



Mr. H. W. Andrews exhibited two specimens of Hilaria aeronetka 

 Mik., a dipteron recently identified as occurring in Britain. They 

 were taken in North Kent on June 20th, and July 28rd, 1910, 

 respectively. 



Mr. Edwards and Mr. Hy. J. Turner exhibited several species of 

 each of two groups of N. American Papilios. (1) The machaon 

 group was illustrated by P. polyxene-s, P. a>it('rias, and Z'. americus, 

 and (2) the i/lancus group, illustrated by /'. (jlaucufi, P. turnus, P. 

 daunm, P. troiliis, and P. eurymedon. 



It was remarked how prolific N. America is in species of Papilio 

 in spite of a more rigorous climate over a large area, compared with 

 the whole of continental Europe which only produced three species. 



Mr. Dennis exhibited numerous lantern slides of lichens in situ, 

 of the flowering of the larch, and of the toothwort [Lathrea 

 squaniaria). 



Mr. Main exhibited an interesting series of lantern slides of the 

 common millepede, Pulydexintis coinplanatus, illustrating his observa- 

 tions so far on their egg-laying and nest-building habits.
