before, Friday, October 10, had been warm, humid and showery 

 in the morning, clearing by afternoon, but the atmospheric con- 

 dition continued. Cyrtomenits nvirabilis being found the follow- 

 ing morning at about ii a. m. dead on clean sand away toward 

 the water from any drift might seem to have been in flight on the 

 day before. The nth dawned bright and warm (70° at 9 a. m.), 

 and warmed up as the day went on. Nothing was found float- 

 ing in on the wash-up except a very few beetles and the Lygus 

 pratensis noted. After noon, at about 3 o'clock, it began to grow 

 a little cloudy, finally getting completely overcast by 8 p. m. and 

 raining heavily. Insects were flying about in the morning, not- 

 ably Eristalis and other hover flies and common Lepidoptera, 

 none of which, however, was found on the tide line. Up to 

 about 4 or so, the wind had blown in steadily and strongly from 

 of the wet weather. The insects were taken on the edge of the 

 advancing tide, which was coming in at about 5 p. m. The 

 the sea, changing at that time to a land breeze with the coming 

 greater part of them was taken between that hour and a little 

 after six. These included both the Acanthias, Ochteriis, Thyreo- 

 coris, Geotomus, Aradus, Perihalus, Alydus, Nysius and Podisus. 

 The Fitchia was taken at about 4, the only bug on the stretch of 

 beach at the Inlet, near the Absecon lighthouse. The poor con- 

 dition of the Podisus, Nysius and Alydus might show that they 

 had been in the water for some time. 



What are the conditions that control these flights leading into 

 the sea? We seem to have now in hand certain data on which 

 to base a temporary explanation. 



Needham says '} " After every on-shore breeze following sun- 

 shiny summer weather some insects are cast up by the waves 

 and there is a great accumulation of them." It was under these 

 conditions that he found large numbers of beetles on the shores 

 of Lake Michigan. 



In 1914 I noted^ a heavy sea-breeze, raw and gusty, with warm 

 weather inland. As I remember, it was a typical October day, 

 with bright sun occasionally obscured by clouds. In 1913, I
