LETTER OF SUBMITTAL, ' 
DEPARTMENT OF AGRICULTURE, 
DIVISION OF ENTOMOLOGY, 
Washington, D. C., June 7, 1886. 
Sir: | have the honor to submit for publication Bulletin No. 12 of 
this Division, which contains certain notes on the work of the Division 
made during the year 1885, and which were excluded for lack of space 
from my report of that year. I have also added a paper on Cicada 
septendecim, sent at my request by the author, and containing many 
interesting original observations, if not always agreeing with those of 
others. 
Respectfully, 
C. V. RILEY, 
Entomologist. 
Hon. NORMAN J. COLMAN, 
Commissioner of Agriculture.
