Meeting of March 20. 



A regular meeting of the New York Entomological Society was held at 

 8:15 P. M., March 20, 1917, in the American Museum of Natural History, 

 President Harry G. Barber in the chair, with 24 members present. 



Mr. Engelhardt under the title of " Collecting at Timber Line, Mr. Hood, 

 Oregon," described his journey in August, 1916, through California and Ore- 

 gon from Sacramento to Portland, and his ascent of Mt. Hood, illustrating 

 his remarks by maps, photographs and specimens. These were collected 

 partly along the margin of the Columbia River before ascending the moun- 

 tain, among surroundings similar to those found in Maine and included some 

 Cychrns and Omiis, and partly near Cloud Cap Inn on Mt. Hood, at an eleva- 

 tion of about 4,000 feet, where there is a virgin forest preserved as a gov- 

 ernment reservation. Carabidae were very abundant at the timber line, and 

 when the sun shone other insects abounded on the numerous hardy flowers, 

 like squaw weed, paint brush, lilies, hellebore, lupines, golden rod and 

 mountain ash, the latter blooming in August at that elevation. Among the 

 butterflies caught were Lycana fuliginosa, pheres, amynUila, antiasis, Chryso- 

 phanus mariposa, Melittia rubicunda, Vanessa milberti, Pyrameis cardui, 

 Chionobas iduna and Argynnis rliodobe. 



Mr. Engelhardt gave a graphic account of the climb to the summit of the 

 mountain, not without danger from crevasses, and of the exhilarating influ- 

 ence of the bitter cold found on the solid ice at the top upon himself and his 

 companions. He was fortunate in having such alternations of sunshine, clouds 

 and snowstorms as to show the mountain under many conditions ; three days 

 were spent on the mountain, affording opportunity of visiting the glaciers 

 and forests as well as the summit. 



Leaving Mt. Hood, Mr. Engelhardt went further north, visiting Seattle and 

 San Juan Island in Friday Harbor on Puget Sound, where the University of 

 Washington maintains a biological station. Two days were spent here, mainly 

 devoted to marine work with a motor boat, but some moths were taken at the 

 electric lights and Argynnis bremmeri and many Carabidae by day. The island 

 is heavily wooded and would repay further eff^ort. 



Mr. Engelhardt's remarks were discussed by Dr. Forbes, Dr. Bequaert and 

 Messrs. Bird and Schaeft'er, the discussion bringing out the record of Vespa 

 austriaca on the Pacific Coast mentioned at- a previous meeting by Dr. 

 Bequaert. 



Mr. Bird under the title " Some Remarks on Parasitism " gave a remark- 

 able account of 1,732 parasites, primary and secondary, from one host, show- 

 ing in detail the processes of nature by which, in spite of the number of 

 eggs laid by the female and the influence of secondary parasites in restrict- 

 ing the operations of the primary, the balance is maintained, so that ordinarily 

 one pair succeeds another. He aimed to show the possibility of following 

 in certain endophytic species, the actual happenings in the field, of the indi- 

 vidual through the whole larval and pupal period, by evidence deduced at the 

 close of the cycle. He detailed in part what befell a thousand individuals
