the moths began to appear, and over 200 emerged, all of them 

 large specimens, ranging from 20mm. to 30mm. in expanse. 



" 5th generation. — Two pairs of the 4th generation moths were 

 removed from the breeding cage, and the females deposited ova. 

 The larvae from these ova fed through July and part of August on 

 dandelion and knotgrass. Some attained the imago stage in late 

 August and early October, 1912, and were of the summer form, 

 others are now in hibernation, together with some larvffi of a sixth, 

 generation."

Mrs. A. E. Gibbs, of St. Albans, and Messrs. Geo. Brooks and 

 Gilbert Storey, of the British Museum (Nat. Hist.) were elected 

 members. 



Mr. Colthrup exhibited a number of excellent photographs of 

 collecting localities in the New Forest, in Surrey, etc., and of the 

 resting attitudes of species of the genera Tephrosia and Boarmia,. 

 showing striking protective resemblance. 



Mr. C. B. Williams exhibited the larvae of two species of the 

 snake-fly, Bhaplddia, E. viaoilicollis and E. notata. He fed them 

 upon aphides, which they ate readily, and supplied them with water. 

 The larva? were obtained at Oxshott, where they were not uncommon 

 in decaying pine stumps. 



Mr. Piatt Barrett exhibited specimens of the true Thera variata, 

 sent to him by Major Eobertson from the New Forest, and asked if 

 the species was to be found in the London district. He pointed out 

 that the larvfe fed exclusively on spruce. He also showed T. 

 obeliscata for comparison.

 which the dark markings were massed at the larger end. 



Mr. A. E. Gibbs exhibited a number of species of Satyrida' and 

 Heaperiida: taken by him during his holiday in the Balkans, and 

 contributed the following notes : — 



" One of the most characteristic butterflies of Dalmatia is the 

 form of Melanari/ia lariam to which Hiibner gave the varietal name 

 of herta. It is a much whiter insect than the nymotypical form, 

 which occurs in the eastern Balkans, while var. herta is found in 

 the west of the peninsula. I did not spend a great deal of time in
