 which I witnessed may have begun in this way. 



StENOBOTHKUS (?) ELEGANS. 



A beautiful little species which Dr. Sharp doubtfully 

 identifies as Stenohothrns elegaiis, 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.EMORRHOIDALIS. 



After 1 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 5. — 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, 

 apparentlij 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 

 energy.
