284 Psyche 
Mnemosyne cubana Stal 1866. 
Myers, Harv. Biol. Lab. and Bot. Gdn. Cuba. Studies on 
Cuban Insects 1 ., p. 15, 1928. 
I saw no specimens of this, the largest of Cuban Cixiidae, 
at Soledad, during February, March and most of April, but 
Mr. R. M. Grey took eighteen specimens (3 males and 15 
females) on the 27th and 28th of April, just after my 
departure. 
The nymphs were discovered by Dr. George Salt while 
we were collecting together near the Mina Carlota, in the 
Trinidad Mountains of Cuba, on 23rd March. He has kindly 
allowed me to quote his detailed notes extensively, as fol- 
lows : 
“A rotten tree stump about 3 feet high on the west side 
of a gully running south of the mine, revealed several large 
brown and black ants (Odontomachus haematoda insularis 
pallens Wheeler) when split open by Myers. The ants are 
able to inflict a most painful sting, grasping the skin with 
the jaws and then doubling the abdomen underneath to 
plunge the sting rapidly in several places within its reach. 
“The ants were traced down in the trunk and below the 
surface of the ground, a few immature stages being found. 
A small colony of a tiny brown ant was found apparently 
entirely enclosed in the larger ant’s colony and later another 
of these small colonies of only 2" diam., in a large chamber 
surrounded by galleries of the larger ant. This later colony 
taken. 
“Two patches of white silky material were noticed among 
the galleries but as parts of them were composed of short 
radiating wheel-like threads, it was thought to be a fungus. 
In one, however, was found a Fulgoroid nymph which crept 
out of this white chamber and which I attempted to catch. 
It was protected by three ants, which, when the nymph was 
lifted, grasped it in their mandibles and were themselves 
carried up by it. Later others were found of various instars, 
from the 2nd to the 5th ; many having a whorl of radiating 
short white silky threads attached to the tip of the abdomen.
