/'si/llijisociis de Selys ; that is the only one I know of with the 

 hind wing showing a forked vein near hind margin. In the 

 fore wing the media varies from two to three branched in the 

 same species. In Psylloneura Enderl. the fore wing is just 

 about the same, but hind wing has not the forked vein; in 

 both, and other Psyllipsocinse, the stigmal vein is fairly 

 straight.'' Psyllipsocus is a living European genus ; Psyllo- 

 neura was based in 1903 on a species from New Guinea, and 

 no other species have been added since. Psyllipsocus ramhuri 

 is sometimes injurious in houses, according to Bertkau. The 

 straight lower edge of stigma and the cubital fork of hind wing 

 appear to be primitive characters. The fossil may be generic- 

 ally distinct from Psyllipsocus, but it seems best to provision- 

 ally refer it to that genus.

 of head ; C, joints of apical half of antenna. 



Termopsis swinhoei n. sp. (Termitidse). 



Length 3 - 8 mm ; black ; wings about 4 - 5 mra long, hyaline, with 

 brown costa ; head of moderate size, the face flat and vertex 

 not conspicuously elevated ; antennae with the joints beyond 

 the middle much broader and larger than those near the base ; 

 legs rather small ; cerci small. .Radius running close to costa, 

 giving off two branches above, one very close to the end, the 

 other not far from it. Media running very close to radius, and 

 giving off obliqne branches. 



So far as can be seen, the structure of the wings resembles 

 that of Termopsis procerus Heer (the type of Termopsis), 

 from the Miocene of Croatia. The radius is however less com- 

 plicated than in Heer's species.
