A total of eighty-eight specimens, belonging to fourteen species 
divided amongst eight genera of one group of butterflies, is a sufli- 
ciently remarkable record for three visits to a strip of ground which 
certainly did not exceed 50 yards in length by 10 yards in width. 
While fully bearing ont Bates’ account, it forms a striking exception 
to Darwin’s rule that nearly allied species are seldom found in close 
competition on the same ground. 
On another occasion IT met with a similar experience. On 
March 28th, 1907, a hot sunny morning, as I was walking along the 
upper water course where it runs through the wood almost clinging 
to the face of the cliff (perhaps a quarter of a mile from the pre- 
viously described locality), passing under the shade of a large tree 
I disturbed a crowd of butterflies so dense that fourtcen were easily 
netted in two or three swoops. Ten of these were pinched, which all 
proved to be Ithomia sylvella, Hew., four of them got away. In this 
instance the butterflies were confined to some four or five yards of 
19 
the narrow path, and it was almost a“ pure culture” of that singu- 
larly delicate little species, indeed, the only exceptions were two 
specimens of Athesis clearista, Dbl., and single specimens of Pfero- 
nymia latilla, Hew., and Dircenna jemima, Hibn. I may add that 
IT have no reason in either case to think that the Ithomines were 
drinking at the stream. 
But besides Ithomiines there were plenty of other butterflies 
along the banks of that stream and the water-courses leading from it. . 
To begin with the less exciting Satyrines. There were Huptychia 
hermes, Fabr. (camerta, Cram.), and the smailer #. pharella, Butl., the
