LIBURNIA SCOTTI. 33 



Pronotum nearly twice the length of the head, with 

 orange streaks and pale keels, which do not reach to 

 the hind margin of the same. Abdomen dark orange, 

 with black dots at the sides. Dorsum black, with dark 

 segmental marks. Elytra two and a half times longer 

 than the abdomen ; yellow, with blackish nervures. 

 Apical portion rich brown, which colour tapers towards 

 the basal end. Wings grey, with brown nervures. 



The point of the serrated ovipositor protrudes beyond 

 the end of the pygofer. This organ, with its sheaths 

 when seen from below, is imbedded in a tuft of cotton- 

 like fibre. 



This insect is marked uncommon by Mr. Edwards, 

 but it has been repeatedly taken in the autumn by Dr. 

 Capron, in the Gomshall marshes, near Guildford.

 the apex. Sometimes this streak spreads into a blotch, 

 and the membrane is suffused with brown. Apical 

 cells four or five. Legs ochreous-yellow, edges of the 

 laminated spur on the tibiae with black serratures. 

 Under-side uniformly yellow. Abdominal apex of the 

 female truncated, with an obtuse, blunt, anal style. 

 This sex sometimes shows a tendency to develop faint 

 barrings on the dorsum. The male is smaller, and the
