Section of Entomology. January 24, 1872. 
Mr. Fred. A. Clapp in the chair. Eleven persons present. 
Dr. Hagen read a paper on the epidermic and. hypoder- 
mic colors in insects. 
Mr. F. G. Sanborn exhibited living specimens of Boreus 
nivoriundus Fitch, recently taken by him on the surface of 
the snow in the “ Bussey Woods,” West Roxbury. This spe- 
cies differs from L. brumalis Fitch in the reddish color of the 
legs and aborted wings, as well as in being slightly larger. 
It leaps on the snow a distance of four inches, but on a sheet 
of paper in a warm room cleared about eight inches at a. 
spring. The female is uppermost during connection. 
Dr. Hagen spoke of the parallelism between these and the 
two Huropean species, which differ in size and color just as 
the American species do. — 
The following subjects were mentioned by the Secretary 
of the Section, as among the most desirable for investigation 
during the coming season ;: — 
1. The insects living directly or indirectly on the “black- 
knot” (Spherium morbosum Schwein) of the plum and wild 
cherry.
