Of other insects collected by me, an earwig nearly 
two inches long, and a giant cockroach, 3^ inches long by 
i£ inches wide, took the honors. Two species of longicorn 
beetles were also common, as well as several varieties 
of spiders, with curiously shaped bodies ending in the 
most wonderful angles and bosses and points, some so 
brilliant to look at, that their bodies seemed to be 
fashioned of burnished metal. A curious sight to me 
was that of some of the more sombre-coloured spiders 
being carried off bodily from out of their webs by an 
immense species of dragon fly, whose bodies were some- 
times quite 4^ inches long, of a pale French-grey colour, 
having their wings barred with a dull orange. 
Locusts, apparently identical with the species (Aery- 
dium vicarium) that ravaged the provision lands in 
Berbice in 1886, were numerous, as my small plot of 
garden plainly showed ; and many branches and small 
twigs were noticed sawn off by the sawyer beetle 
(Prionus cervicornis) , but no specimens of the insect 
were obtained. 
Several nights in succession towards the latter end of 
my stay, I had to abandon reading and to put out all lights 
owing to the clouds of insects (Ephemeridse) that swarmed 
round the smallest spark. So numerous were they, 
that in the mornings the river was quite white with their 
bodies ; and earlier still, before the sun gained power, 
the flight of these swarms was so thick and persistent 
that it reminded me of a snow storm. 
One of the most curiously interesting creatures 
observed by me, was a species of fly which frequently 
entered my benab : never more than one at a time, but 
the most sociable animal it is possible to imagine !
