NOTES ON THE Lli'E-HlSTOKlES OF NATAL TERMITES. 113 



Notes on the Life-Histories of Natal Termites, 

 based on the Observations of the late Mr. 

 G. D. Haviland. 



By 

 Ernest Warren, D.^cLond. 



The material for this paper is drawn from the work of the 

 late Mr. G. D. Haviland. This careful and keen observer had 

 resided for some years in Natal^ and, as is well known, he had 

 done most valuable work on the termites of Natal and of the 

 Malay region. 



In the Linnean Society's Journal, vol. xxvi, 1897, Mr. 

 Haviland published an important paper entitled " Obsei"va- 

 tions on Termites, with Descriptions of New Species," which 

 is a systematic memoir on the species of termites which had 

 come under his notice. 



Subsequently to the publication of that paper he made 

 many interesting observations on the habits of the Natal 

 species, and these were carefully recorded in diaries and in 

 other manuscript notes. 



In addition to these observations, Mr. Haviland made an 

 extensive series of measurements of the breadth of the head 

 of the various castes in the nests of certain species, more 

 especially of Termes natal en sis. The measurements were 

 undertaken with a view to determine the mutual relationships 

 and variabilities of the different castes. The investigation is of 

 special interest in that in this species there is but one queen 

 and king in a nest from which all the castes originate.
