PLATE XIIL 



LiBURNiA CAPNODEs. (Page 41.) 



Fig. 1. — Brachypterous female, showing the rudi- 

 mentary wings and obhqnely rounded pygol'er. 



Fig. 2. — Head, pronotum, and scutelkim of the male, 

 with its faintly marked keels. The pronotum, by 

 pressure of the head downwards, shows itself as a 

 kind of hood, and that it overlaps the scutellum below. 



Fig. 3. — Elytron and wing of the male. Part of the 

 costa and the apical periphery is thickened, and the 

 band is seen marked by strong striations. The minor 

 thickening of the wing by error has been omitted in 

 my figure. 



Fig. 4. — Hind tarsus and claw much enlarged. 



Fig. 5. — Frons, clypeus, proboscis, and antennae 

 of the male. The basal joint is annulose. 



Fig. 6. — Part of the peripheral band of an elytron, 

 with the nervures bearing setigerous hairs. 



LiBURNiA PALLiDULA. (Page 42.) 



Fig. 7. — Macropterous female, with folded elytra. 



Fig. 8. — Male insect, showing the rudimentary wings 

 below the spread elytra. 



Fig. 9. — Pygofer of the female with its anal tube. 



Fig. 10. — Pygofer of the male, with its anal tube, setae, 

 lateral plates, and spatulose sheath. The singular 

 bristles of the penis are worthy of note. A somewhat 

 similar apparatus may be seen on Plate XII., fig. 8. 



LiBURNiA scuTELLATA. (Page 44.) 



Fig. 11. — Macropterous male. 



Fig. 12. — Elytron with wing of the same. 



LiBURNiA LEPTOSOMA. (Page 44.) 



Fig. 13.— Brachypterous form, with its tridentate 

 abdominal apex and its white bordered elytra.
