GLASGOW SOCIETY OF FIELD NATURALISTS. 27 



SPECIMENS EXHIBITED. 



Mr. J. Harvie exhibited, under tlie microscope, a number of 

 Diatoms collected at the last two excursions. 



Mr. P. Camei'on exhibited specimens of the following: — Lestes 

 sponsa, a dragon-fly taken at Fossil Marsh ; the somewhat rare bee, 

 Bombus scrimsheranus, from the same locality ; a saw-fly, Allantus 

 costalis; and a curiously-coloured specimen of Ghrysis ignita. 



Mr. A. Watt exhibited specimens of dried grasses, with beetles 

 fastened to them, among which wei-e the common British species, 

 Gasterophysa raphani and Getonia aurata, the majority, however, 

 being foreign Buprestidae. These were procured from a milliner's 

 stock, and are specimens of what is at present fashionable for 

 ladies' head-dresses. 



Mr. Gr. Horn exhibited Ophioglossurti hcsitanicum from Jersey; 

 and Mr. E,. M'Kay, Geum urhanum in full flower, collected in the 

 neighbourhood on the 26th April, being a month earlier than its 

 usual time of flowerino-. 



EXCURSIONS. 



-Mr, R. M'Kay, conductor, stated that an unsuccess- 

 ful search had been made for Gryptogramme crispa, which at one 

 time grew on the Drymen K-oad. The two somewhat rare mosses, 

 Glyphomitrium Daviesii and Grimmia Doniana, were found at the 

 Whangie. Isoetes lacustris was found abundantly in Cochno Loch. 

 ToUcross and Kenmuir. — Mr. P. Cameron, conductor, gave an 

 account of the excursion. The spring bees (Andrenidae), usually 

 abundant on the sand hills at this season of the year, were found 

 to be very scarce, owing to the prevalence of the east wind. The 

 common Oil-beetle (Meloe proscarabaeus) was seen in greater 

 numbers and earlier than usual. Two other Coleoptei'ous insects, 

 Amara fulva and Pteristlchus lepidus, were also collected. Through 

 changes in the locality, the latter is being gradually exterminated. 

 The habits of a spider {Lycosa picta), which forms tunnels lined 

 with a web in the loose sand, were also noticed. At Kenmuir, 

 the galls of Andricus noduli were observed to be very abundant 

 on a small oak tree. This gall-fly has not previously been reported 

 for Scotland. The fresh-water mussel, Unio margaritifer, was 

 found to have disappeared from most of its old stations.
