Xll PROCEEDINGS OF THE 



The Chairman (Dr. Stirton) exhibited specimens of Mnium 

 riparixim, Mitten, from the neighbourhood of Auchterarder, 

 Perthshire. 



Mr. Peter Cameron, Corresponding Member, exhibited speci- 

 mens of Figltes anthomyiarum, Bouche\ from Possil, and 

 Dicevaza urticeti, Dbm., from Bishopton. On looking over 

 some duplicate Cynipidce in his collection he had found these 

 species, which are not recorded in his Catalogue of the Scottish 

 Cynipidce recently published by the Society. Both insects, 

 however, have been found by him in England, and may there-

Mr. Adolf Schulze read a paper descriptive of the new 

 apochromatic micro-objective and compensating ocular lenses 

 of Dr. Carl Zeiss, Jena.* At the close of the meeting a number 

 of test objects, such as Amphipleura pellucida (half-a-dozen 

 valves in one field showing all their cross-markings most dis-

 Pleurosigma angulatum, Heliopelta, Podura-sccdes &c, were 

 exhibited under the new apochromatic lenses; and as a proof 

 of the photographic excellence of these objectives, negatives of 

 most of the above-mentioned objects (including Amplxipleura

 the table.
