which accompanies the description and serves to illustrate the 

 venation of this insect. The description given by Dr. Scuddei runs as 

 follows : 





"The few insects that have been hitherto found in the Leda clays or in similar 

 horizons in America have all been Coleoptera. The present specimen, of which a 

 figuie is here given, enlarged six diameters, is a cadis-fly; one of the Neuroptera. It 

 was found by Dr. Henry M. Ami, of the Geological Survey of Canada, in the nodules 

 of Green's Creek and sent me for examination. It is of a glistening, dark, smoky 

 S\ brown color, with black veins which are 



followed with some difficulty, especially 

 where two wings overlap. The clearest and 

 most important pari of the neuration is in 

 the upper portion of the lore-wing ; but un- 

 fortunately it exhibits in full only the princi- 

 pal cells. These are enough to show that it 

 is a caddis-fly, and that it falls near, if not in 

 the genus Phryganea proper, but it differs in 

 important points from all the species I have 

 examined in the Museum of Comparative 

 /.oology at Cambridge, containing the large 

 collection of the late Dr. Hagen. The 

 difference consists principally in the great 

 length of the thyridial area and of the median 

 cellule, so that the distal termination of the

It represents a tolerably large species, the 



preserved fragment being 10 mm. long and 



the probable original length of the fore-wing 



at least 15 mm. It may be called

THE MICROSCOPICAL SOIREE. 



The opening Conversazione and Exhibition of Microscopical 

 objects and Natural History specimens took place on Tuesday evening. 

 26th. November last in the large Assembly Hall of the Normal 

 School, Ottawa, on which occasion there were upwards of 200 

 persons present. An address of welcome by Dr. J A. McCabe, M.A., 

 F.R.SC , Principal of the Provincial Normal School opened the 

 proceedings, after which Dr. R. W. Ells on behalf of the Ottawa 

 Literary and Scientific Society, of which he is president, read a short 

 paper on the future work of societies of this kind in Ottawa in which he 

 strongly urged united effort and advocated the scheme, of lectures now 

 carried on in Montreal, known as the " Somerville Lectures" endowed
