MEETING OF BIOLOGICAL CLUB. 
Orton Hall, Dec. 4, 1911. 
The meeting was called to order by the President, W. M. 
Barrows. The minutes were read and approved. The Club then 
had the pleasure of listening to an interesting lecture by Prof. 
Herbert Osborn on “Some Collecting Trips in Western States.” 
The trips of which Prof. Osborn spoke carried him through about 
forty states and territories. Their principal object was the study 
and collection of Jassidae affecting various forage crops. Certain 
of these insects were found to be strikingly adapted to conditions 
which must have prevailed for a long period of years. The talk 
was illustrated with a number of excellent lantern slides and was 
followed by an interesting discussion. 
The meeting closed after a short business session in which 
Messrs. Schlopp, Mote, Busby and Bilsing were elected to mem- 
bership. 
C. L. Metcalf, Secretary.
