Exhibitions. 



Mr. C. J. Watkins sent for exhibition a series of larch twigs 

 illustrating the winter condition of Coleophora laricella, the 

 special feature being the manner in which the cases of the 

 larvse assimilated in colour with the bark of the larch. 



Mr. G. B. Routledge exhibited a specimen of Hydrilla 

 palustris taken on the wing by Mr. J. E. Thwaytes when 

 " sugaring" near Carlisle on June 10th, 1899. He said it was 

 the first male taken in that district. Mr. C. G. Barrett 

 remarked that it was the most definitely marked specimen of 

 any known, and that in the northern locality the lines on the 

 wings seemed to be brought out with greater distinction than in 

 the fen country and elsewhere. Mr. Thwaytes also exhibited 

 specimens of Bembidium schuppeli, a rare beetle captured on 

 the banks of the river Irthing. 



Mr. R. McLachlan exhibited Trichopterous larva-cases of 

 the form known as " Helicopsyche " from the Prony River, New 

 Caledonia, sent to him by Mr. J. J. Walker, R.N. They were 

 large and remarkable for the size of the individual sand- 

 grains of which they were built up. These sand-grains, Mr. 

 Walker informs him, were water-worn particles of the heavier 

 minerals of the river bed, such as chrome, nickel, and iron 

 ores. It is possible that similar cases were alluded to by 

 Hagen in the Stett. Entom. Zeitung, 1864, p. 129, from the 

 Munich Museum,
