JANUARY 8, 1885. 
Ten persons present. President Riley in the chair. 
The election of officers then took place, and the officers of the 
Society for the year 1884 were re-elected for the year 1885. 
Dr. Riley exhibited a specimen of the larva of the Dipterous 
genus Scenopinus found by Dr. E. Bessels infesting the blanket of a 
Navajo Indian. He related the history of Scenopinus pallipes 
as observed by Mr. Sanborn and remarked upon the species of 
the genus hitherto observed in the United States. Mr. Schwarz 
pointed out the great external resemblance of this larva to that 
of the Coleopterous genus' Cardiophorus. 
Dr. Marx reported the discovery of the male of the Arachnid 
genus Gasteracantha by Mr. H. G. Hubbard, of Crescent City, 
Florida. 
MARCH 12, 1885. 
Eight persons present. Vice-President Morris in the chair. 
The Corresponding Secretary read a letter from Mr. Lawrence 
Johnson, of Gainesville, Florida, in relation to a number of 
insects observed in Florida injurious to vegetation, among them 
more especially a Pyralid larva injuring Paw-paw (Asimina}. 
Mr. Mann offered some remarks on the advisability of exact 
transcription of titles in making references to publications, as 
otherwise such works often could not be identified with certainty 
by the titles quoted. 
Mr. Schwarz exhibited twigs of Sumac (Rkus glabra] in- 
fested, and probably killed, by a Scolytid beetle, Pityophthorus 
consimilis, and remarked upon the work of this species. 
The President then delivered his annual address : 
ANNUAL ADDRESS OF THE PRESIDENT. 
FELLOW-MEMBERS : Your president has experienced some dif- 
ficulty in choosing a subject upon which to address you as required 
by our constitution. Our Society is too young for retrospect, 
while a review of entomological events of a general char- 
acter is in a measure forestalled by the various publications de- 
voted to our science and by the English and German Zoological
