the Yoho Valley was reached through Yoho Pass and the camp maintained by 

 the Canadian Pacific Railroad near Takaka Falls was visited. Here Syrphids 

 were found in large numbers in the tents, probably attracted by their white walls 

 and torpid from the chilly night air of 4,800 feet elevation and surrounding 

 snow and glaciers. From Laggan Dr. Osburn went to Lake Louise, which he 

 described as the most soul-satisfying spot in the world ; there excellent collect- 

 ing was found on the edge of the lake and in the trails through the woods, 

 where the thick vegetation was often knee deep and even above the head in 

 many places. Notwithstanding the distractions of the scenery, glaciers, snow- 

 clad mountains, lakes and waterfalls, 1,000 Syrphids and 1,500—2,000 insects of 

 other orders were taken on the journey, which will be referred to in greater 

 detail at subsequent meetings. 



Mr. Davis exhibited and discussed " A New Cicada from Northeastern 

 America," the description of which will appear in the Bulletin of the Brooklyn 

 Entomological Society, New Series. He also spoke of other species of Cicada, 

 particularly Cicada pruinosa, which he said was abundant in a piece of woods near 

 Cape May, N. J., in 19 10, but very scarce at the same place and season in 

 1912, leading to the conclusion that it, like the 17-year locust, takes a number 

 of years for larval growth and consequently appears in broods at regular inter- 

 vals, the length of which might easily be ascertained by systematic collecting 

 over a term of years in the woods in question. Other interesting species 

 exhibited were Cicada sayi var. anstralis from Georgia, a series collected in 

 part by J. Chester Bradley ; Cicada engelhardti, perhaps a variety of C. lyricen, 

 once supposed to have been confined to the Cumberland region, but recently 

 found near Greenport, L. L ; and the following four from Florida, viz., Cicada 

 pallida, found in April in the meager pine woods in the interior of Marco 

 Key; Cicada hieroglyphica, occurring at Lakeland March 28 and May 5, 6 and 

 7 and extending thence north to Lakehurst, N. J., where it appears in June ; 

 Cicada parvula, found in low vegetation only two or three feet from the ground, 

 occurring north to North Carolina, where Manee says it emerges from the pupal 

 skin in the ground; and Cicada sayi, found at Labelle. Mr. Davis said this 

 species did not differ from New Jersey specimens in characters or in song, by 

 which in fact he recognized it at first, and then climbing the tree in which it 

 rested, detected its position by the excited waving of the abdomen and caught it. 



Mr. Wintersteiner spoke on " Experiences in Collecting Hydrophilidse ' 

 and exhibited a remarkable collection of these water beetles. He mentioned the 

 capture of Ochthebius foveicollis on Myriophillum growing in stagnant water 

 in July ; stated that Berosus aculeatus, distinguished easily by testaceous abdo- 

 men, is not uncommon near New York, and gave minute information respect- 

 ing the habitat and characters of all the local species, many hertofore imper- 

 fectly known. This paper will be printed in full in the Journ.^l. 



Dr. Osburn read a paper on Odonata, which he stated would be turned 

 over to the publication committee for insertion in the Journal along with one 

 by Mr. Davis on local species. 



This paper was discussed by Dr. Forbes and Mr. Davis, particularly in
