In my experience tliis is the laziest ant in India ; though not 

 uncommon, I have never seen it do anything but ' loaf.' 

 Mr, Rothney, however, says : — " This species is not uncommon in 

 " Bengal, and forms its nests by excavating the earth round the 

 " trunks of trees, throwing it up in mounds of very fine grains, 

 " away from the trunk, and so making a ditch or fosse round the 

 "tree. The winged sexes ' swarm ' July 7th to 10th, and are very 

 "handsome in appearance. There was (and probably still is), a nest, 

 " or rather colony, at the big banian tree in Barrackpore Park, near 

 "the Trunk Road, which I have known from 1872 to 1886, not only 

 " is the main stem more or less encircled by these ditches, but many 

 "of the minor ones are partly surrounded by earthworks, some 

 " being completely so. It forms the largest ant- work I have met 

 " with in India. These fosses make excellent traps for other insects, 

 "and a very respectable and miscellaneous list of captures can 

 " always be made from them, such as other species of ants, woodlice, 

 "bugs, cockroaches, &c., &c. These, if so inclined, one might 

 " describe as ant-^pets,' but I have never been able to trace the least 

 " connection between these casuals and M. subcarinaia, and I think their 

 " presence is purely accidental. As regards food-supply, M. subcarinaia 

 "lives much like a pol//rachis." *

* Since the above was written, I have seen this species in Kanara, where it is very 

 common. It is there, as described by Mr. Rothney, a great "crater" builder.
