70 ENTOMOLOGICAL SOCIETY 
the three years 1898-1900, while no annual address was 
delivered for either of these years. Each of the other presidents 
held office for two consecutive years, and one of them, Dr. 
Riley, the first president, was especially honored by the 
Society in that it elected him its president at four different 
times an honor never since conferred upon any of its members. 
During the twenty years of its existence our Society has 
published six volumes of its Proceedings; three of these 
appeared during the first eleven years, and the other three 
during the remaining nine years. These volumes are veritable 
storehouses of biological facts and also contain much matter 
of special interest to the student of systematic entomology, 
attesting the wide-awake interest and unremitting efforts of 
the members. 
Mr. Fairchild exhibited a collection of photographic repro- 
ductions of the portraits of famous botanists, published by 
Prof. Wittrock of Sweden. He called especial attention to a 
series of portraits of Linne at different ages, the first one 
taken when about 30 years of age and ending with a copy 
of a reproduction in wax taken at an advanced age. 
Mr. Schwarz, referring to Linnaeus, mentioned a published 
bibliography of the latter which is very little known or referred 
to. This is the one by Dr. C. A. Dohrn, President of the Ento- 
mological Society of Stettin, published in the Stettin Entomo- 
logische Zeitung. 
Dr. Stiles spoke in favor of the formation by the Washington 
Entomological Society of a collection of photographs of its 
members. He believed that this should be begun at once, 
since it would soon be difficult, if not impossible, to secure 
photographs of the older members, and the collection would 
very soon come to be highly prized. After some discussion 
Dr. Stiles's suggestion in the form of a motion was seconded 
and carried. 
Dr Hopkins read the following paper:
