STENOBOTHRUS (?) ELEGANS. 
A beautiful little species which Dr. Sharp doubtfully 
identifies as Stenobothrus elegans, was often seen, although 
not abundant, below the hotel. The males in stridu- 
lating, do not, like the two last mentioned species, move 
the third legs symmetrically, but one follows the other. 
Probably in consequence of this the sound swells and 
diminishes rhythmically, presenting a remarkable likeness 
to that made by a fly caught in a spider’s web. Con- 
sidering its very small volume, this high and piercing 
sound can be heard for a great distance. 
STENOBOTHRUS H#MORRHOIDALIS. 
After I left, F. Jenkinson observed a very small kind 
which is almost certainly to be identified as the above 
named species. Mr. Jenkinson has kindly given me the 
following notes :— 
“SEPTEMBER 9.—About 5 p.m. I found a very small 
brown male, with the dorsal surface of the abdomen of a 
reddish-orange colour. He was very assiduous in his 
attentions to a green female with white V-shaped marks 
on the side of the thorax. He generally kept close to 
her, but was never obtrusive in his attentions, relying 
apparently on the effect of his stridulation. This was 
made with both legs simultaneously, generally very low, 
but sometimes louder, a rapid uniform trill, rather like 
the note of the lesser whitethroat. Sometimes she gave 
him the slip, and they were as much as eight inches 
apart, and out of sight of each other; but he continued 
at short intervals his stridulation, and somehow, 
apparently by accident, they came across each other 
again, and the male posted himself in close attendance 
as before. The female was generally nibbling at blades 
of grass. If the male touched her, she seemed to repel 
him by raising one of the third pair of legs. At 6°45 
the sun was setting, and I had to go, so I boxed them 
both. The male was perhaps just beginning to relax his 
euergy.
