of egg parasites from eggs deposited in the stems of bean plants and 

 expects to publish a report concerning the matter in the near future. 

 The writer, however, has never noted egg parasites issuing from eggs 

 laid in alfalfa stems. 



Dr. A. K. Fisher, of the Bureau of Biological Sur\'ey, United States 

 Department of Agriculture, informs the writer that they have found 

 stomachs of nighthawks to contain specimens of Stictocephala which 

 these birds must have taken quite early in the evening. Messrs. R. N. 

 and T. Scott Wilson, during September and October, 1913, killed 31 

 birds that were visiting alfalfa fields, and 10 of these had from one to 

 four adults of Stictocephala jestina in their crops. Table VIII shows the 

 results of an examination of the stomachs of these birds. The birds were 

 determined by Mr. Frank W. Rogers, State game warden of Arizona.

The same investigators killed 19 toads but only found three of these 

 to have Stictocephala festina in their stomachs. One stomach contained 

 one nymph and three adults, while two others contained one nymph 

 and one adult, respectively. One would think that toads might feed 

 upon the nymphs to a considerable extent, but the dissections of these 

 19 stomachs seem to prove the contrary.
