larvae and pupae being carried by the workers. In some, the pupa is 
free, in others in a silken cocoon which the larva itself prepares. 
An interesting feature of ants, especially of the fiercer and more 
war-like species, is the fact that they are mimicked by other insects 
extremely closely. Sima rufonigra is mimicked by a Sphegid Rhinopsis 
ruficornis, Cam., in Barrackpore and by Rhinopsis constancece , Cam., in 
the Konkan. It is also commonly mimicked by a spider, as is Sima 
nigra. Wroughton records the mimicry of a species of Polyrhachis by 
the nymph of a Coreid bug Dulichius inflatus , Kby. (Proc. Ent. Soc., 
Bond. 1891, p. XVII). 
Bingham lists the Indian species in Vol. II of the Fauna of India, 
Hymenoptera, based on Forel’s papers (Jo. Bo. Nat. Hist. Soc., VII, 
etc.). In this volume 498 species are enumerated as Indian, of which 
those mentioned below are common in the plains with a fairly wide 
distribution.
