PLATE a. 



Tettigid^ in Amber. (Pages 181 — 183.) 



Fig. 2. — Typhlocijba resinosa, Germ. & Ber. Charac- 

 terized by a want of ocelli, by an elliptical imder side, 

 and by the vertex being somewhat arcuate, and by the 

 strongly spm-red hind tibiae. 



Fig. 9. — Tijphlocijha cnccnistica, Germ. & Ber. Lower 

 border of the pronotum emarginate. Elytra somewhat 

 romided, each having a white costal spot, which is still 

 preserved on the elytra of some recent species of 

 Typhlocyha. 



Fig. 11.^ — Jassus immcviius, Germ. & Ber. Nearly 

 allied to Jassus sidphureUa, but it is larger, and appa- 

 rently differently coloured. The specimen is obscured 

 by an opalescent tihn. Fig. 11 a. — The antenna. 

 Fig. lib. — The elytron. N.B. — This species would 

 appear to be more nearly allied to Bythoscopus. 



Fig. 13. — Tettiyonia proavia, Germ. & Ber. Head 

 obtusely acute. Pronotnm puncto-striate. " Seems to 

 be in close relation to North American and Brazilian 

 species." Bather longer than our Tettiyonia viridis. 

 Fig. 13 a and fig. 13 h probably are the larva and pupa 

 of the same species. The ocelli are prominent in these 

 last insects. 



Fig. 19. — Cixius testudlnarius, Germ. & Ber. 



Fig. 20. — Cixius insignis, Germ. & Ber. 



Fig. 22.^ — Cixius longirostns, Germ. & Ber. This 

 specimen was wanting in many details, but its porrected 

 vertex and long rostrum may be noted as distinctive. 



Fig. 26.- — Cixius gracilis, Germ. & Ber. Upper side. 



Fig. 26. — Cicada Forsythii, mihi. Enclosed in copal- 

 resin. From Zanzibar. Details only of the under 

 side have been made out. The outline of the frons 

 and clypeus have been lost.
