August, '13] SEVERIN: TRAPPING MEDITERRANEAN FRUIT FLY 351 



Ehrhorn (1912, p. 4), superintendent of entomology in the Hawaiian 

 Islands, writes as follows concerning the number of male and female 

 Mediterranean fruit flies captured in kerosene traps. "Among the 

 various experiments tried against the fruit fly, the use of kerosene traps 

 has shown that enormous quantities of male flies can be trapped by 

 this method, but so far very few females have been captured." The 

 results of our investigations with the use of kerosene to trap the Medi- 

 terranean fruit fly were read in Honolulu before the Agricultural Seminar 

 on November 9, 1911, and January 11, 1912, at which this entomolo- 

 gist was present and yet Ehrhorn has published this result as well 

 as other observations which we announced at these scientific meetings 

 without due credit being given to our labors.
