198 Mr. G. A. James Rothney's 
as described by Mr. H. S. Ferguson, in "Our Ants/' 
or as Mr. Wroughton concisely puts it in the same 
work when speaking of Anochetus sedilotii, " the 
action is distinctly that of a ^ skip-jack^ beetle, and 
not that of a grasshopper ; but the best fas seul 
is but a sorry performance, and to see and appreciate 
the really wonderful springing powers possessed by this 
ant, you must stir up a nest crowded with the winged 
sexes and ready to swarm. 
I also found this species in Travancore, but the nests 
contained only workers, December 6th to 10th, and 
consequently there were no fireworks. 
The click-click of hsematodes is the only self- 
produced sound that, beyond the possibility of a doubt, 
I have met with amongst Indian ants. 
Anochetus sedilotii, Emery, race indicus, Forel. 
Bhavnagar, also a nest in the compound of the New 
Guest House, Baroda, where I found the workers 
hunting after sunset. I did not succeed in making them 
jump. 
Diacamma vagans, Smith. 
Mr. Wroughton does not mention this species as 
occurring in Bombay, but if anyone wishes to study 
this most interesting ant they can find her in the 
Victoria Gardens, hunting about the roots of some 
bamboo clumps which grow on the side of the gardens 
by the ornamental water. 
Diacamma geometricum, Smith. 
Common in Bolghetty, Cochin, several nests being 
established in the wall which surrounds the Residency 
kitchen garden ; in ways and manners she is exactly 
like vagans, 
Ponera jerdonii, Forel, 
found in some numbers amongst the debris of stacks 
of firewood in Barrackpore, and also under the same 
conditions in the Botanical Gardens, Calcutta.
