the Malay Peninsula, viz. L. meges and L. curins. Captain 

 Godfrey, from Perak, writes that L. meges was generally 

 found overrunning streams, and that the transparent wings 

 and long streaming tails gave it to some extent the appear- 

 ance of a dragon-fly, but its flight hardly bears out this re- 

 semblance, consisting of a kind of dancing motion, a series of 

 mid-air jumps different from the swift flight of a Lihellnla ; 

 still the rapid vibration of the wings strongly reminded him 

 of the dragon-fly. Mr. Forbes, in remarking on the way 

 L. virescens derives protection from mimicking the habits 

 and appearance of a dragon-fly in the island of Sumatra, 

 says it reminded one of some of the European Neuroptera ; 

 he goes on to say that when it settles on the ground it is 

 difficult to see as it vibrates in constant motion its tail and 

 wings, so that it is a mere haze, as it were. 



Mr. Tunaley remarked on the abundance of larvae, espe- 

 cially on oaks. In some places the larvae of Tceniocampa 

 miniosa were extremely common. In the discussion which 

 ensued several members adverted to the fact that this year 

 the defoliation of the oaks was due not so much to the 

 attacks of Tortrix viridana as to the larvae of the various 

 species of the genus Hybernia. Some members had seen 

 rooks in the defoliated trees, but whether they v/ere seeking 

 the lepidopterous larvae or not could not be ascertained. 

 It was noted that the oiks having bright green foliage were 

 comparatively free from attack, whereas the trees having 

 dark greenish-brown foliage had suffered the most. This 

 was especially noticeable in Epping Forest. 



/UNE i^th, 1896. 

 R. South, Esq., F.E.S., President, in the Chair, 



Mr. West, of Streatham, exhibited a bred series oi Hypsi- 

 petes riiherata, one specimen being almost uniformly dark, 

 and another having only a dark band ; a specimen of Tro- 

 chilimn crabroniformis, bred from an osier stem cut at Streat- 

 ham, from which he had expected to breed Sesia formiccE- 

 formis ; and a specimen of Gordiiis aqnatiais found that 

 morning in damp earth in his garden. 



Mr. Robert Adkin exhibited a series of Eupithecia venosata, 

 bred this spring from larvae taken in the island of Hoy, 

 Orkney ; together with series of the same species from 

 Shetland, Forres, and the Isle of Man, for comparison, and 

 remarked that although there was a great similarity among
