although marked large and designated a town on some maps, it 
scarcely deserves the distinction, even in Guiana, where towns are 
scarce and qualification is low. It has this attraction to an entomolo¬ 
gist, that it is surrounded with forest. Here, in a tumhle-down, 
timber-built structure called an hotel, I put up for a month, making 
excursions all round. As my brother, who I have forgotten to mention 
was with me, was anxious to see at least one of the falls of the Maza- 
runi, we next day hired a boat, engaged a crew of eight, took ham¬ 
mocks and provisions for three days, and set out for a coviander’s hut, 
the good boviander’s name being Fransook. We did not arrive here 
until it was pitch-dark—about seven p.m.—and all thought of col¬ 
lecting had to be abandoned, at least for day flyers. A large acetylene 
lamp was part of the impedimenta, and to this a few moths turned 
up, hut a full moon was shining at the time or the result would, no 
doubt, have been very different. Next morning we were up at the 
regulation hour of five, and, although warned, we could scarcely 
believe that our clothes, although protected, were quite wet with the 
heavy dew. Having pushed off at six, there were visions of great and 
many things by twelve. Here and there on some of the flowering 
vines, large numbers of the pale yellow tJatopsilia statira were to be 
seen, with an occasional C. aryante, also some of the common 
Xymphidiums oi the Erycinidae were frequently seen, but it was impos¬ 
sible to work for these insects in such situations. The first fall, or 
cataract, was negotiated, and soon afterwards the first named fall, 
which has the very English name of Marshall, was safely passed. 
Immediately after passing this camp was pitched, and before I had 
the net ready a splendid Morpho rhetenor and M. neoptolenuis passed 
us. This was the only occasion on which I saw M. rhetenor, but the 
latter was seen frequently afterwards and sometimes brought inside 
the net. Incidentally I may mention that all about this cataract 
orchids are growing in some profusion. Oncidium altminuuii was in 
flower, and w : e measured specimens with flower spikes 12'.6” long. 
Lepidoptera were not at all plentiful here, and as everything was so 
dry I put it down to that cause, lthmnia zarepha flitted about among 
the dead leaves, and it has since struck me very forcibly that the 
bluish tinge to the wings seems to disappear in course of time. It 
seems to be pretty generally considered in the colony that the falls and 
cataracts in the rivers are the best places for orchids, and I expect 
that in the season close following the rains lepidoptera are also plen¬ 
tiful in these situations. The natural beauty of these falls where the 
river is studded with islands is most attractive, and the shooting of 
the falls is somewhat exciting, especially after the rains. On the way 
back Vapilio thoas was found, commonly flying along the Catabo road. 
“ Road,” I should mention, here means simply a cleared passage in 
the forest. In this case the road has not been kept open, and has now 
become covered with thick underwood, almost the invariable sequel to 
these clearings. Heliconim rhea was in abundance ; a II. ynarica and 
II. cathannae were also taken. I should have liked to have explored 
this road, as the day was very favourable, but as arrangements had 
been made with the crew to return to Bartica, tracks were made for 
the boat. Our feelings can be imagined when w r e returned and found 
the boat was high and dry on the mud, the tide having gone out, and 
our boys asleep. There was nothing to be done except exist as we
