1000 ft., and one was taken at La Brea. A female hydarus had 
such a strong Witch-hazel odour that it was quite perceptible 
through the net; two males, in which little or no scent could be 
detected during life, had a decided scent when their papers were 
opened at Oxford three weeks later. Two euryades were taken 
above St. Ann’s, and another in a wood at San Juan, but this species 
did not appear to have a strong scent. The rich golden-brown 
JEueides aliplnera aliphera, Godart, was rather common on the Ariapeta 
path at about 100 ft., and appeared to be more or less gregarious in 
its habits; both sexes had a strong smell like stables. It is curious 
that the Nymphalines of the genus Dione have the same odour; they 
are also very similar in general appearance to Eueides. 1 
The Nymphalinae are very well represented in the New World, 
and therefore in Trinidad, but the genus Colaenis , which I had found 
so prominent in Jamaica, was during my flying visits to Trinidad 
met with but once, in the person of a single female, C. julia , Fabr.; 
while the nearly allied Dione was represented by a single male, vanillae. 
On the other hand, the more humble-looking Phyciodes leucodesma 
was abundant. Of Synchloe lacinia, f. saundersi , I captured one 
at San Juan. A male Precis lavinia was intermediate in character; 
at San Juan, on April 2nd, Anartia amalthea was common about a 
small swamp, but it had lost its beauty, the specimens being mostly 
tattered: on April 14th it was seen above St. Ann’s, at an elevation 
of 1000 ft., in much better condition, but in that locality also it 
showed a partiality for water. A. jatrophae , common enough at the 
time of my first visit in January, was evidently over, a tattered male 
being all that I saw of it. A single specimen of Adelphia cytherea , 
Linn., occurred high up the path. The pretty little Dynamine 
theseus, Feld., was locally common at about 800 to 1000 ft.; one 
example had the black borders to the hind-wings broader than usual. 
At La Brea a specimen of D. postverta , Cram. ( mylitta , Cram.), was 
picked up and another missed; it has a beautiful underside. The 
two large grey butterflies, Peridromia feronia , Linn., and Ageronict 
ferentina i Godart, which are as much alike as their names are con¬ 
fusing, both occurred in the same open flowery part of the wood on 
the Ariapeta path, at about 1000 ft. above sea-level — one of my 
favourite spots. They are alike hard to catch. The first-named 
settled on grey tree-trunks, looking like a large Boarmiid moth, and 
almost as cryptic, but always head downwards; they were, however, 
very shy and easily disturbed, though returning again and again to 
the same tree. I have already referred to Darwin’s observations on this
