MONTHLY LETTER OF THE BUREAU OF ENTOMOLOGY. 
U. S. DEPARTMENT OF AGRICULTURE, 
21. January, 1 91 6, 






. The issue of Science for December 17 contained an important announcement re- 
garding the recent work of Dr. W. V. King. In experiments conducted in one of the 
daboratories of the Medical Department of Tulane University Dr. King determined 
that Anopheles punctipsnnis is an efficient carrier of the tertian form of malaria. 
‘The importance of this discovery lies in the fact that A. punctipennis is a very 
widely distributed species in the United States and had not previously been deter- 
‘Mined definitely to be an efficient carrier of any form of malaria. The discovery, 
) therefore, has a very important bearing on antimalarial work in this country. A 
» full report on the experiments will appear in the February issue of the American 
Journal of Tropical Medicine and Hygiene.
