Doings of Societies. 



Feldman Collecting Social. 



Meeting held April 16, 1919, at the residence of H. W. Wenzel, 5614 

 Stewart Street, Philadelphia. Seven members present, Pres. H. W. 

 Wenzel in the chair. 



Mr. Ernest Baylis, of Frankford, Philadelphia, Pennsylvania, was 

 elected a member. 



Diptera. Mr. Hornig saidthat A'cdcs canadensis Theob. is now on 

 the wing, taking at this time of the year 31 days to mature from the 

 egg, while at the height of the season it will take about 11 days. 



Coleoptera. Mr. Geo. M. Greene recorded seeing Hydrous triangu- 

 laris Say at light during the evening of April 8th, and the next day 

 Creophilus villosus Grav. and Platynus cupripcnnis Say on the side- 

 walk. Mr. H. W. Wenzel mentioned some new varieties of Cychrus 

 lately named, after which there was a general discussion on the genus. 

 Mr. H. A. Wenzel exhibited a large series of Hylecoetes luguhris Say 

 which he had collected at West Overbrook, Pennsylvania, IV-13 and 14 

 in a poplar log which he supposed had been dead about a year. The 

 bark was slightly loose and in the sap beneath had found the beetles, 

 just ready to emerge. They bore in the wood similarly to Scolytids, 

 but one peculiarity was noted on the specimens of the wood shown — it 

 is vertically grooved and ridged alternately and all the beetles had 

 emerged (as far as they had gone when found) through the ridges 

 and none in the grooves, though by coming through the latter they 

 woi'ld have had less wood to bore through. The sexes are quite 

 unlike and the males have wonderfully feathered palpi which are 

 much larger than the antennae — George M. Greene, Secretary. 



Meeting of May 21, 1919, at the same place. Ten members were 

 present, Dr. J. C. Bradley, of Cornell University, and Mr. John H. 

 Hodgins, of this city, visitors. President H. W. WenZel in the chair. 



Dr. Bradley detailed collecting trips he had taken to the cafions of 

 the Colorado Desert, Southern California, in December, 1917, and 

 March. 1918. 



Coleoptera. Dr. Castle read a letter from Mr. Leng, dated April 7, 

 saying he had seen the records in the minutes of the January meeting, 

 published in Ent. News xxx, p. 120, 1919, relative to Scaphinotus 

 ridingsii Bland. He enclosed a separate in which he described this 

 form which should be S. ridingsii monongahelae Leng. Dr. Castle 

 also had a newspaper clipping from "The San Francisco Examiner," 

 M^-'-h 16, 1919, on "Experts hunt winter home of ladybirds," in which 

 was described the manner of collecting the Coccinellids in winter time 

 after they hibernate in great numbers under the pine needles at the 

 snow line in the mountains of California. These are placed in cold 

 storage and later liberated in the orange groves to destroy the aphids
