decided, angular black line closely borders the apex, 

 and sometimes there is a paler line near the base. 

 Eyes red. Pronotum with four or five brown streaks, 

 which sometimes unite into a single stain. Scutellum 

 an equilateral triangle, with the scull-like marking so 

 commonly seen in Idiocerus and some former genera. 

 Abdomen yellow, with faint brown bars ; each segment 

 with a triangular dorsal mark. Pygofer of the male 

 with two large genital valves, forming a notch, fur- 

 nished with strong bristles, and a conical cauda. 

 Elytron rounded at the apex, and provided with a faint 

 apical border. Nervures pale and whitish ; membrane 

 ochreous or pale brown. Wings short and grey. Legs 

 yellow, with dark tibial and femoral points. The hind 

 tibia with a black inner streak. The outer edge fringed 

 with strong bristles. Some examples have the pro- 

 notum prettily mottled with grey, whilst other specimens 

 are nearly all pale yellow. A brachelytrous form 

 occurs, the elytra of which are shorter than the 

 abdomen. 



Size, 0"21 inch, or 5*60 millimetres. 



Fairly common in many places amongst grasses, 

 from early May to July. Also taken under dead oak- 

 leaves, at Weycombe, May 4th, and at Wakefield in 

 June. 



The basal fore tarsal joint is so small that the foot 

 might be called di-merous. The frons is convex, and 

 has seven bars across it.
