HETEROPTERA IN OCEAN DRIFT. 1 
By J. G. Myeks. 
The presence of occasional terrestrial insects or their remains, 
in beach drift is a phenomenon of little ethological significance; 
but the occurrence on some rare occasions, under circumstances 
but little understood, of considerable windrows extending some- 
times for miles along the beach and often consisting of little else 
but insects, is a matter for legitimate speculation. 
In 1915 Torre Bueno published extensive records of Heterop- 
tera found in drift on lake and ocean shores, and in 1917 Parshley 
made further observations on this phenomenon. Mr. P. J. 
Darlington makes a practice of examining such drift on the 
Massachusetts coast for Coleoptera, and he has kindly given 
me four small collections of Heteroptera from this material. 
Though the species present are not extremely numerous, the 
circumstances of season and composition render them worthy of 
record as modifying certain conclusions of previous writers on 
this obscure subject. 
In the lists which follow, the species marked B were present 
also in Torre Bueno’s material, while P indicates those observed 
by Parshley.
