Mr. Walker's description of this species is evidently taken from the two insects (male 

 and female) from Ceylon — the colour characters in part from the male [T. ceylanica, 

 mihi), the size from the female. The male in Mr. Moore's collection is very similar to 

 our female, excepting that it is smaller.
