side by side, pushing and kicking at each other, and 
stridulating alternately. One male had lost one of the 
third pair of legs, perhaps in an earlier part of the 
fight, but if so it must have been somewhere else, as I 
searched for the leg in vain. In spite of its mutilation 
it replied with its single leg to every stridulation made 
by the other, and these replies seemed especially irri- 
tating to the uninjured male for it kicked more vigor- 
ously than ever, and once made a determined but unsuc- 
cessful effort to bite the end of the other’s abdomen. The 
fight was already raging when I began to observe. After 
I had watched it for several minutes the uninjured male 
gave up and went away. It is possible that the fight 
may have begun by one male leaping on the other in 
mistake for a female, but it is more likely that it arose 
in a quarrel over one female. This view derives some 
support from the following observation. 
SepreMBer 2.—At a certain spot on the slopes below 
the Bella Tola the species was very common, and several 
pairs were seen in coitu. ‘lhe female is larger and 
duller in colour than the males, and her wings are much 
smaller and probably useless for flight. 
In the case of one pair in which copulation had 
evidently only just taken place, the female was seen to 
expel feces: another male was lying beside the pair 
evidently trying to copulate with the female, continually 
stretching his abdomen towards her with partial eversion 
of the organs. He also stridulated from time to time, 
and I feel almost sure, although I cannot speak with 
certainty on this point, that the copulating male replied 
on each occasion. In a few minutes the unsuccessful 
male went away. I have suggested that the fight may 
have begun in some such contest, but probably before 
either male had succeeded in pairing. IJ cannot now 
remember whether the stridulation during the fight and 
on the occasion last described was similar to that which is 
characteristic of the species at other times. I am con- 
fident that no new sound was introduced, but cannot be 
sure as to whether both movements were made with 
their usual relation to each other. 
Sepremper 7.—F. Jenkinson saw two males of this 
species drawn together from a distance of several yards 
apparently as the result of stridulating alternately. 
When at length they met, they seemed much excited,
