Mandibles very strong, their inner margin furnished with teeth. 

 Pronotum narrower than the head, nearly flat. Cerci and styli are 

 1 ong or even very long. 



The workers appear to be larval in shape. 



In all castes the tarsi are of the same structure, but a plantula is 

 present in the Imago only. 



The genus Termopsis was established by Heer in 1 849 for the 

 reception of several fossil species from the amber of Oeningen (Prussia). 

 In 1856, Hagen restricted Heer's genus by showing that several of his 

 species had to be placed in Bodotermes, and in 1858, in the descriptive 

 part of his Monograph of the Termites, he described the first living 

 species, Termopsis anyusticollis, from California. At the same time 

 Hagen also placed in this genus, although in doubt, a peculiar soldier 

 from Central America formerly described by Walker under the mime 

 Tennes occidcntis. I am, however, convinced that this does not really 

 belong to Termopsis, a question which can be ultimately confirmed by 

 the discovery of the winged form. 



It was therefore a matter of the greatest interest to me to see that 

 there wa also a living Termopsis in the Indian Region, and I was 

 most astonished that such a large and peculiar "white ant" had 

 remained so long unknown.

 Winged Imago. — Length of the body about 11 millimetres, to the tip 

 of the wings 25 mm. 



Head large, rounded, the upperside nearly flat, sometimes with the 

 centre very slightly depressed, rather dark reddish-brown, darker in 

 front ; the Y-suture distinct. 



Antennse long, longer than the head and pronotum, of 24 or 25 

 segments; the 1st segment large, cylindrical; the '2nd smaller than the 

 1st but always longer than the 3rd ; the 3rd to 5th segments variable 

 in length : in some cases the 3rd is but little shorter then the 2nd, in 

 others it is much shorter, being broader than long ; the 4th is either 

 subequal to the 5th or longer, or shorter ; the segments beyond the 5th 

 are more or less conical, differing but little in length, becoming more 

 slender towards the apex of the antenna.
