TIm' clavus has become separated and lost. Dr. 10. P. 

 Van Duzee kindly examined my drawing, aud suggested the 

 reference to the vicinity of Aphrophora. The principal 

 dilVerence from modern Aphrophura is in the strongly bent 

 media, which might justily a special generic name. The 

 general appearajice of the insect is suggestive of Cercopis 

 Jasciata, lleor, l^^al}, from the Miocene of Kadoboj in Croatia. 

 The name given by Heer is preoccupied by Fabricius, so the 

 Croatian fossil may be called Cercopis (?) heerij n. n. 'I'he 

 fctssil now de:?cribed is dedicated to the author who tirst 

 reported a Cercopid from the Gurnet Bay depo^^it, though he 

 erroneously recorded it as the modern Triec2)hora sanguino- 

 U'litiij whicii, according to Van Duzee, is the type of Cerco^Hs.
