NORTHERN TERRITORY TERMITIBjE. Part i. 



By Gerald F. Hill, F.E.S., Government Entomologist, 

 Northern Territory. 



(Plates xiv.-xxiii.) 



The following contribution to a knowledge of the Australian 

 Termitidce lias been prepared from part of a large collection of 

 Termites, and many field-notes compiled during the past two 

 years, in what may be termed the coastal region of the Northern 

 Territory. 



Fifteen species are dealt with in this paper, eight of which are 

 described as new. One new species is recorded from Melville 

 Island; the remainder are from localities situated within 70 

 miles of Darwin, and within 20 miles of the Darwin-Pine Creek 

 Railway. The Departmental collection contains about 27 species 

 from the latter area, but it is probable that the number will be 

 brought up to 30 or more when the whole collection has been 

 worked out. 



In the absence of the winged forms, it has been found impos- 

 sible to determine accurately several common species of the genus 

 Eutermes. These, and a few species of the genus Termes, which 

 are represented in the collection by one or two examples only, 

 have been held over until more material is available for study. 



I desire to express my thanks to Mr. W. W. Froggatt, Govern- 

 ment Entomologist of New ^outh Wales, for his courteous assist- 

 ance in determining many species submitted to him, and to 

 acknowledge the help I have derive^ from a perusal of his works 

 on Australian Termites. 



Heterotermes validus, sp.nov.

 paler; wings pale fuscous tinged with ochreous, nervures fuscous;
