10 SPOLTA ZEYLAJS'ICA. 



T. redemanni, Wasmami. 



" Wien. Eut. Zeit./' XII., Pt. 7, p. 239 (1893). 



Tlie commonest of the moimcl-building species in Ceylon. 

 Widely distributed. Kandy ; Colombo ; Ambalangoda ; 

 Trincomalee ; Hambantota ; Jafifna ; and probably throughout 

 the Island. 



T. obscuriceps, Wasmami. 



" Zool. Jahrb.," XVU., Pt. I., p. 113 (1902). 



Another common mound-building species. The mounds 

 indistinguishable from those of redemanni, but the insects 

 easily recognizable by their dark brown heads. Apparently 

 not so widely distributed as the previous species. Recorded 

 from Peradenij^a and Diyatalawa. 



T. escherichi, Holmgren. 



" Termitenleben auf Ceylon," p. 195 (1911). 



A smaU species, occurring m dead tree stems and under 

 decayed logs. Peradeniya. 



T. preliminaris , Holmgren. 



" Termitenleben auf Ceylon," p. 196 (1911). 



While describing this as a new species, from winged adults 

 caught " around a lamp at the Peradeniya resthouse," Dr. 

 Holmgren suggests that it may possibly be referable to some 

 other species of which the adults are as yet unknown. 



T. taprohanes, Walker. 



" Cat. Neur. Brit. Mus.," p. 522 (1853). 



{Syn. peradeniyae, Holmgr. '' Termitenleb. Ceyl.," p. 197.) 



This species has hitherto been imrecognized by recent 

 workers. Dr. Holmgren has now identified specimens from 

 Peradeniya and Koslanda as referable to this species, but 

 suggests that it is equivalent to Jiorni. He also relegates his 

 peradeniygs (described from winged adults only) to taprobanes.
