The retiring President, Mr. P. G. Bolster, then gave the address: “Re- 
marks on the History of the Cambridge Entomological club.” 
Materials for this paper were gathered from the records of the club 
and proved to be of great interest. Mr. J. H. Emerton, who attended 
many of the earlier meetings and who was one of the original organizers 
or the club added some recollections to Mr. Bolster’s remarks. The 
progress of the club was reviewed from the first meeting at the home 
of Dr. Hagen at Cambridge down to the present date in so far as the 
records were available. Lists of the officers of the club, addresses of 
the retiring presidents, and much other data of historical interest were 
given. Mention was also made of the number of prominent entomolo- 
gists throughout the country who have, at one time or another, been 
members of the club. Mr. Bolster closed his remarks by recommending 
that an index of the records be made for the valuable and interesting 
data that appear in them. 
C. A. Frost, Secretary. 
Meeting called to order by President W. M. Wheeler at 8 o’clock. Twenty 
members and two visitors present. 
The Secretary being absent, Mr. H. S. Smith was appointed to act as 
Secretary pro tem. 
Mr. Fiske gave a talk on “Hypermetamorphosis among Insects.” The 
various types of hypermetamorphosis as defined and designated by Packard 
and as encountered in the work at the Gipsy Moth Parasite Laboratory 
were not at all analogous to each other Mr. Fiske stated. These 
phenomena fall distinctly into two groups, the one typified by that type 
of hypermetamorphosis occurring in certain beetles (Rhipiphoride, 
Meloéide) and the Hymenopterous genera Perilampus and Orasema, the 
other typified by that form of development occurring in certain Procto- 
trypids (Inostemma, Platygaster) and most of the Ichneumonids (Ophion, 
Theronia, Limneria, Ichneumon). The former he designated as Incom- 
plete Hypermetamorphosis and the latter type as Complete Hypermeta- 
morphosis. 
The president asked Mr. Fiske to take the chair while he read a 
review of “A Monographic Revision of the Twisted-Winged Insects of 
the Order Strepsiptera Kirby” by W. Dwight Pierce. This paper was 
discussed by Messrs. Brues, Johnson, Fiske and others. 
Mr. Newcomb exhibited some interesting photographs of hybrids and 
variations in the butterfly genus Basilarchia. He also showed an interest- 
ing melanistic specimen of Argynnis cybele from northern Wisconsin. Mr.
