TERMITIDAE 



383 



The species is called A. panficus by Fritz Miiller ; it differs from 

 other Termitidae in possessing a proventriculus destitute of tritu- 

 rating ridges. The nests of this species are utilised by a little 

 Eutermes {E. inquilinus Miiller) for its own advantage ; whether 

 by first destroying the Anoplotermes or whether by merely taking 

 possession of the nests abandoned by their owners is not known. 

 It is a most remarkable fact 

 that the Eutermes resembles 

 the Anoplotermes so ex- 

 tremely that the two can 

 scarcely be distinguished, 

 though anatomically they are 

 quite different. The resem- 

 blance is indeed so great that 

 it deceived Yon Jhering into 

 supposing that the two genera 

 were alternate generations of a 

 single species, one generation 

 possessing soldiers, the other 

 being without them. Subse- 

 quently, by anatomical inves- 

 tigation, he recognised^ the 

 error into which he had fallen 

 — an error that, under such 

 peculiar circumstances, was 

 quite pardonable. 



Hagen has suggested^ that 

 Hodotermes japonicus never pro- 

 duces winged forms. Very 

 little, however, is actually known as to this species. 



Marching and Harvesting Termites. — Smeathman alluded 

 to a remarkable Termes seen by him in Africa, giving it the 

 name of T. viarum. Nothing further is known of this Insect, 

 which, according to Smeathman's account, may possibly be the 

 most remarkable of the family. T. viarum is said to be larger 

 than T. bellicosus, and was discovered issuing in large numbers 

 from a hole in the ground and marching in columns consisting 

 of workers directed by soldiers of enormous size, some of whom
