The illustration on the front cover of this issue is of Dr. Hermann A. 
Hagen, Professor of Entomology and Curator in the Museum of Compara- 
tive Zoology at Harvard University from 1870-1893. Professor Hagen, 
along with S. H. Scudder, provided the initiative for the founding in 1874 
of the Cambridge Entomological Club and its journal Psyche, now in their
