the saw-case. Styles elongate-triangular, outer margin straight, 

 inner margin concave in the middle and cut off obliquely to a 

 sharp point. Length, 2 — 2i mm.

Lihurnia Boldi, Scott, Enfc. Mo. Mag., vii., G8, 13 ; 

 Fieb., Cicad. d'Eur., pt. iv., 17, 15 (?). 



Crown yellow, keels white, interstices black. Face j'ellow, keels 

 white, the middle one on each side and the side ones inwardly 

 margined with black. Pronotum and scutellum yellow, with a 

 greyish shade, keels distinct, somewhat paler than the disc, side 

 keels of the former almost reaching to the hind margin. Elytra 

 yellowish grey, barely covering half the abdomen, hind margin 

 rounded, nerves not pronainent nor granulate, apex of clavus some- 

 times with a short narrow dark brown streak. Abdomen (male) 

 above black, with a fine rust-red dorsal line, apex of each segment 

 of the connexium yellow-red ; female, above brownish yellow, 

 darker on the sides, side margins orange-yellow, outer margins of 

 the segments black, a fine dorsal line and the hind margins of the 

 segments pale. Styles (PI. II., fig. 17j short and broad, inner margin 

 strongly, outer margin faintly, concave, inner apical angle produced 

 into a pointed tooth, outer apical angle produced and bluntly 

 rounded, thus giving to the style a form very suggestive of a profile 

 view of a bird's head and neck. Length, 2 — 2^ mm. 



Sandy coasts. Near Newcastle-on-Tyne and Norfolk. 

 It is impossible to be quite certain that the insect above

 tion of the female, the only sex he knew, agrees very 

 well with the female of the insect here characterised.
