and submedian slender, the former divided into one or more forks 

 at the extremity. 



1. Genus Termes. (Recent and fossil.) 

 Head large, rounded; eyes large, and prominent, finely faceted, 

 ocelH present; antennae 13-20-jointed; prothorax heart-shaped; 

 flattened, smaller than the head. 



2. Genus Eutermes. (Recent and fossil.) 



The form of head and thorax very similar to that of IWmes; 

 wings always dark coloured, with the base of the nervures in the 

 scapular shield not as robust as in the latter. Soldiers always 

 nasuti. 



3. Genus Anoplotermes. (Recent.) 



A genus formed by Miiller on the internal anatomy of a 

 Eutermes from Brazil (A. pacificus). He also places Eutermes 

 ■ater, Hagen, and E. cingulatus, Bui'm., with the new species. 



CaLOTER MIXING. 



Mastotermes, g.n. 



Head large, nearly as broad as long, flattened ujjon the summit; 

 eyes large, projecting ; ocelli prominent ; antennas SOjointed; 

 clypeus large, labrum rounded at the apex. Prothorax shaped 

 like that of Galotermes, except that it is turned up on the outer 

 edges, with the scapular shield as long as the meso- and metathorax. 

 Eore wings differing from the hind pair in venation in having 

 fewer parallel nervures between the costal and subcostal, the 

 upper portion of the wings crossed with stout nervures, with the 

 whole of the wing finely reticulated with smaller veinlets. Tibise 

 with four spines at the apex; claws large with a small plantula. 



This genus is founded upon a species from Port Darwin, W. 

 Australia, and is allied to Calotermes.
