Genere Gypon&x Homopterorum, quod a GERMAR !) anno 
IMDOCCXXI e genere Cercopis a FABRICIO descripto secretum 
est, dux et quinquaginta ad hoc tempus cognite species con- 
tinentur. Quarum FABRICIUS annis MDCOLXXXVII?) et 
MDCCCIII?) sex species descripsit, Sar?) anno MDCCCXXV 
unam, quam ad genus Tettigonie referebat, BURMEISTER 3) an-

MDCCCLI unam, STÅL 'annis MDCCCLIV 7), MDCCCLXII 2); 
MDCCCLXIV ?9) sex et triginta, UHLER !9) denique hoc anno 
unam.

Earum ad numerum, que ante erant cognite, mihi, ut 
novas quingue et quinquaginta species adderem, contigit. At-
