PLATE XI. 



LiBURNIA SMARAGDULA. (Page 34.) 



Fig. 1. — Macropterons winged male, with its broad 

 anal plates. The ramifications of the elytral nervm*es 

 may be compared with those of L. sciitellata, Plate XIII. 

 (N.B. — The yellow markings on the abdomen are too 

 pronounced in my figm^e. The fine green colour of the 

 living insect soon fades in cabinet specimens.) 



Fig. 2. — Brachelytrous female of the same. It is 

 much larger than the male, and it has almost obsolete 

 elytra. 



Fig. 3. — Head, pronotum, and scutellum of the 

 imago. 



Fig. 4. — Part of the hind tarsus and the tibial spurs. 



LiBURNIA uNicoLOR. (Page 35.) 



Fig. 5. — Macropterous male showing the projecting 

 vertex. When at rest the hind legs are often crossed 

 so as to show only the tarsi. 



LiBURNIA coLLiNA. (Page 35.) 



Fig. 6. — Macropterous male, which is almost uni- 

 formly ochreous yellow. 



Fig. 7. — Brachypterous female, drawn of relative size 

 to the preceding figure. 



Fig. 8. — Short elytron, with its dotted nervures. 



Fig. 9. — Frontal view of the head, with its central 

 undivided keel. 



Fig. 10. — Under side of the last abdominal segments 

 of the female, with its saw-case and anal process. 



LiBURNIA ELEGANTULA. (Page 36.) 



Fig. 11 — Brachelytrous male. In some specimens 

 the scutella are nearly black.
