to Rin.) 
males of many Indian species of the genus Mutilla (closely 
allied to the ants), particularly the common Mutilla sea- 
maculata, stridulate freely; they always stridulate when in 
the net. The females will also occasionally utter sounds, but 
in a very mild and modified degree. (Hcophylla smaragdina, 
when you disturb a nest, make a loud noise, but I believe 
this to be the pattering of thousands of feet on the hollow 
leafy nest. Wroughton, in his excellent work, ‘‘ Our Ants,” 
records an observation of Aitken’s of the noise made by 
Lobopelta when disturbed on the march; but I have never 
heard this noise, although I have met with many marching 
columns of this ant. 
Yours very truly, 
G. A. James Roruney.”’ 
Dr. Sharp remarked that G@cophylla belonged to the sub- 
family Formicides, in which no instruments of stridulation 
have been detected, and also that he had quoted in his 
paper the opinions of Messrs. Aitken and Wroughton on the 
subject. 
A long discussion ensued, in which the President, Canon 
Fowler, and Messrs. Champion, McLachlan, Goss, Hampson, 
Barrett, Jacoby, and Burns took part. 
Mr. C. J. Gahan read a paper entitled ‘‘ Notes on the 
Longicornia of Australia and Tasmania, Part I.; including a 
list of the species collected by Mr. J. J. Walker, R.N., and 
descriptions of new forms.”
