NOTES ON TERMITES FROM CEYLON. 103 



and soldiers were congregated. But it seemed to me that the 

 winged individuals were emerging not onty from these two 

 places, but also between and beyond them. In those gather- 

 ings the worker caste seemed to be far predominant, as I 

 found about a dozen soldiers only amongst a large number 

 that I swept into a tin, whereas the number of workers 

 exceeded two hundred. 



The next morning I examined the place, but could find no 

 signs of the presence of T. horni, except some shed wings. 

 Neither could I discover the openings from which they had 

 made their exit the night before, nor did I find any traces of 

 them or of their nest in the neighbourhood. 



I have thought it worth while to describe this exodus of 

 T. horni, incomplete as my observations are, because this 

 phenomenon has been observed very seldom, and all we have 

 to go upon is Mr. Fetch's account of three such events observed 

 by him in relation to T. obscuriceps and T. redemanni, 



Anoplotermes CYCLOPS, Wasra. 



Our knowledge of this species is very incomplete. All we 

 know is that, in common with the other species of the genus, 

 it is distinguished by the absence of the soldier caste, and that 

 it is to be found under stones and logs of wood. Habitat, 

 Peradeniya and Maha Iluppallama. 



I have found this species on four occasions : once at Kurune- 

 gala, under a stone (December 12, 1912), and three times at 

 Peradeniya, once (December 16, 1912) in a mound of Termes 

 redemanni, which An. cy clops shared with the host and 

 Capritermes incola. The next day I found another colony, 

 also in a nest of redemanni ; and on the fourth occasion 

 (December 18, 1912) I found it in a mound of Termes obscuriceps, 

 inhabited, moreover, by Hamitermes quadriceps and Eutermes 

 escherichi. There is nothing unusual in the occurrence of 

 Anoplotermes in the mounds of other species. Such an 

 association has been already recorded by Holmgren in the 

 case of the South American species An. reconditus, which 

 occurs in the nests of Termes dims.
