Lema palustris Blatchley. A nice series of this rather 
uncommon beetle was taken in Framingham on June 16, 
1929, by sweeping the budding plants of the Canada thistle ; 
a week later they had disappeared entirely. Previous to 1913 
this species was considered to be brunnicollis Lac. which is 
a more southern species.
