successful in finding her again than any other species I 
have observed. At 5°30 the male jumped on the 
posterior part of the female’s body, his legs round her 
teomina. In this position he continued to stridulate 
although at rare intervals (he did so at 5:50). The 
female carrying the male shifted backwards moving her 
abdomen. She seemed to have some difficulty in expelling 
feeces, and this was apparently the cause of the movement. 
The male stridulated, and then at 6:0, without having 
copulated, he quitted the female, stridulated, and went 
away.” 
PsoPHUS STRIDULUS. 
The large black males were common just below the 
hotel, and on some slopes below the Bella Tola, where 
Stethophyma fuscum abounded. Their red under wings 
were very conspicuous when flying, the characteristic 
rattling sound still further attracting attention to them. 
The larger brown, toad-like females; with smaller wings, 
are probably unable to fly. 
I never saw the sexes together; but after I had left, 
F. Jenkinson kindly sent me the following notes :— 
“* SepreMBER 5.—When the male finds himself near a 
female, he utters a double ‘ twitter’ (once a twitter and 
then a trill), and moves excitedly. In one case I saw 
him leap on the back of a female, but presently he left 
her of his own accord. 
“ At 3 p.m. I came across a pair in coitu, but the male 
disengaged himself by vigorous movements of the third 
legs. They remained for a long time within two inches 
of each other, but nothing happened. I made the female 
jump away, caught her, and put her in the male’s way. 
He at once became excited, and twittered, but the female 
escaped. This occurred more than once, when I lost 
her. 
«‘ A male, disturbed as 1 came home (about 6°45 p.m., 
when the sun was setting), hopped vigorously, but did 
not open his wings.” ‘This latter observation is of inte- 
rest, because the males always took to flight, when dis- 
turbed, on other occasions. 
“ SepreMBerR 7.—On placing the female near the male, 
he became excited, and made a twittermg sound with 
his legs. The female, in moving off, showed the red
