Through the courtesy of Dr. Y. SjOSTEDT, I have been able to examine 

 a termite collected in the Juan Fernandez Islands off the western coast of South 

 America during the Swedish Expedition 1916 — 17. It is the first termite de- 

 scribed from these islands and has proved to be a new species which I am 

 referring to Neotermcs. 



Kalotermes (Neoteriiies) gracilignathus, n. sp. 



Imago: 



Head medium brown, roundish with rather straight sides; a light dot in 

 the center of the forehead; Y-suture indistinct. 



Antennae with 17 segments, the 3d a little longer than the 4th. 



Eyes small, subtriangular, more than their own diameter removed from 

 the lower margin of the head. 



Ocelli of medium size, fairly close to the eyes. 



Postclypeus narrow, hardly distinguishable from the front. 



Pronotum on the margins a little darker than the head; wider than the 

 head. The type specimen has the sides of the pronotum bent downward (Fig. 

 a shows the pronotum withou tthe sides bent down). Posterior margin angular 

 and slightly emarginate. 



Meso- and metanota with a dark line in the center not reaching to the 

 posterior margins. 



Pulvillus present between the claws of the tarsi. 



Wings brownish, transparent. In the type specimen the media in all four 

 wings joins the radial sector about Vs the length of the wing from the base. 

 The media is not as strongly chitinized as the radius. In immature imagos 

 the media also joins the radius but it also has branches that run out to the tip. 



Abdomen about the same color as the head.
