160 BIOLOGY OP NORTH AUSTRALIAN TERMITES. 



of the tree suffers for many years, so that the actual loss in timber felled for 

 splitting is not great. I have, however, seen some very fine timber rendered 

 valueless for bridge-building and other heavy work, which was otherwise suitable 

 for the purpose. Although capable of doing so much damage to the hardest 

 woods, I have rarely found them destroying fences or buildings.

In a recent paper (1921) I described the alate form of the a,bove species 

 from a nest series collected in the type locality (S.W. Australia), the identification 

 having been made from the original descriptions of the soldier and worker castes. 

 This identification has since been confinned by Rev. Father Wasmann after com- 

 parison of my material with the types. 



In referring to the affinities of this species, I stated that the alate form of 

 C. miehaelseni Silv. is unknown, whereas a full description appears in Professor 

 Silvestri's paper (1909). The differences in both the alate and soldier caste are 

 so marked that the two species cannot be confused.
