As to the season, it is interesting that Parshley’s three 
records of the phenomenon in question occurred between 21st 
June and 1st August, while Bueno’s observations, extending 
over a considerable number of years, were made in July, Sep- 
tember and October. Mr. Darlington’s first two lists are then 
apparently the first to be compiled in spring. 
With regard to supposedly collaborating circumstances, 
Parshley noticed that “in each case there was a light on-shore 
breeze with fair weather, and in none was the occurence preceded 
by an unusually violent off-shore wind, though on the day before 
the last a moderate land-breeze was observed.” Bueno notes 
that on at least one of the occasions when he collected ocean 
drift there was “a heavy sea breeze.” In the present cases Mr. 
Darlington recognizes certain weather conditions as necessary 
for renumerative drift collecting; but these conditions seem to 
depend more upon warmth and bright sunshine acting as stimuli 
to extensive flights, than of direction of wind. The wind on 19th 
May for instance was quartering, but blowing rather more on- 
than off-shore; while on the 22nd, the direction of the breeze 
was practically parallel to the beach. On both these occasions, 
and in fact on all days when collecting was well rewarded, ac- 
cording to Mr. Darlington, the weather was hot and insects were 
observed flying in the sunshine. 
As an example of the form in which the material is found, 
the drift on 19th May was said to consist of a broken windrow 
extending for about half a mile. The most common constituent 
insect was a Bibionid, which made up more than all other species 
combined. Next most abundant were Coleoptera and thirdly 
Heteroptera.
