Genus Termopsis, Heer. 



Heer, Insektenfauna von Oeningen, 1848. 



Head lai'ge, rather oval, broadest behind and suborbiculate; 

 eyes small, oval, not very jjrominent; ocelli wanting; antennae 

 long, 23-27-jointed. Prothorax small, not wider than the head 

 semicircular, flat. Legs long, robust, furnished with tibial spines 

 and plantula. Wings as in Calotermes. Abdomen egg-shaped; 

 anal appendages long, 6-jointed. 



This genus contains three species described by Heer and Hagen 

 from fossil specimens in Prussian amber; and two existing species, 

 one from Manitoba and California, and the other from the west 

 coast of South America. 



Nothing particular is knawn about the habits of the existing 

 species, but the genus is evidently closely allied to Calotermes. 



Genus Parotermes, Scudder. 



Proc. Amer. Acad, of Arts and Science, 1883. 



This genus was formed by Scudder for the reception of three 

 fossil species found in the American Tertiaries of Colorado, U.S. 

 He says, " These species are most nearly allied to Termopsis and 

 Calotermes, but differ from each of them in points wherein they 

 differ from each other, and have some peculiarities of their own. 

 They differ from Calotermes in their shorter wings (relative to the 

 length of the body), which lack any fine reticulation, and in their 

 want of ocelli. From Termopsis they differ in the slenderer but 

 yet shorter wings without reticulation; their uniform scapular (sub- 

 costal 1) vein running parallel to the costa throughout, and pro- 

 vided with fewer and straight branches. From both they differ in 

 the presence of distinct inferior branches to the scapular vein, but 

 especially in the slight development of the intermedian vein and 

 the median vein, the excessive area of the externomedian vein, and 

 the course of the latter, which is approximated much more than 

 usual to the scapular vein and emits branches having an unusually 

 longitudinal course."
