destroyed the Wellesley College insect collection, he pre- 
sented a series of Coleoptera to help replace it. His col- 
lection at the time of his death contained about 60,000 
specimens of Hymenoptera and beetles, in excellent condi- 
tion and labeled not only with collecting data but with 
authoritative identifications and the sources from which 
they had been received. The collection might serve as a 
model for orderliness and for care and accuracy of annota- 
tion. Together with part of Mr. Bolster’s entomological 
library it has been presented to the Museum of Compara- 
tive Zoology, at Harvard College, by his widow and son, 
Charles S. Bolster, Harvard ’15. It adds materially to 
the museum collection, and the specimens, which have been 
individually labeled “Percy Gardner Bolster Coll’n,” will 
remain as a monument to Mr. Bolster’s skill and patience 
as an entomologist. 
It is with the deepest sorrow that the Cambridge Ento- 
mological Club records the loss of Mr. Bolster, one of its 
least assuming but most helpful members.
