70 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



MEETING OP JULY 7, 1910. 



The 242d regular meeting of the Washington Entomologi- 

 cal Society was held at the Saengerbund Hall, 314 C Street, 

 N. W. The following members were present: Messrs. Allard, 

 Barber, Gill, Heidemann, Hopkins, Knab, McAtee, Phillips, 

 Popenoe, Quaintance, Rohwer, Schwarz, and Dr. Arthur 

 Neiva, of Brazil, a visitor. 



In the absence of the Secretary, Mr. Popenoe was appointed 

 secretary pro tempore, and the reading of the minutes of the 

 previous meeting was dispensed with. 



The evening was spent with short notes, in the absence of 

 papers. Mr. McAtee presented notes on the oviposition and 

 other habits of Goniops chrysocoma observed on Plummer's 

 Island, Maryland, and exhibited photographs and specimens 

 of the fly and its egg masses. 1 He referred to his previous 

 communication concerning the habit of Empidae in carrying 

 prey while in copulation, and noted that the asilid Promachns 

 ruiipes sometimes does the same. The male of a pair captured 

 near Afton, Virginia, September 19, 1909, was feeding on the 

 large hymenopteron Anoplitis relativus. 



Mr. McAtee recorded a dragon fly {Rrythemis simplicicollis) 

 as a mosquito enemy. On Church's Island, North Carolina, 

 September, 1909, this species was seen to pick Anopheles qnad- 

 rimaculatns off the weatherboarding of a house. The same 

 dragon fly was captured feeding on another dragon fly {Enall- 

 gama durum} which was almost its equal in bulk. 



Mr. McAtee observed the jassid Ccelidia subfasciata oviposit- 

 ing in a chestnut-rail fence in Rockfish Valley, Virginia, Sep- 

 tember 23, 1909. Each oviposition required from ten seconds 

 to one minute and the intervals varied between the same limits. 

 Specimens of all insects mentioned were shown. 



Mr. McA tee's communications were discussed by Messrs. 

 Knab, Barber, Schwarz, and Heidemann. Mr. Barber men- 

 tioned other observations regarding Goniops. Mr. Knab spoke 

 of the habits of the Empidse. He stated that the fact that, in 

 certain species at least, the female feeds during copulation has 

 been repeatedly recorded. The statement has also been made
