Vertex narrow, obtusely angular in front. Pronotum 

 pentagonal ; the anterior border forms an obtuse angle, 

 whilst the posterior border is slightly curved at its 

 union with the scutellum. Frons with a feeble middle 

 carination, and with two strong depressions towards 

 the lower half, divided by a channel. Frons hexagonal. 

 Clavus with two nervures and a distinct suture. Elytra 

 membranous, punctured, non-limbated, and provided 

 with strong nervures, which form five apical cells, three 

 ante-apical, and one discoidal cell. Rostrum reaches 

 to the second coxas. Basal tarsal joint rather shorter 

 than the last joint. Ocelli placed on the angle of each 

 frontal fork. 



Whole insect deeply punctured ; general colour of a 

 tawny yellow. Eyes red and projecting beyond the 

 width of the pronotum, which last in the male is of a 

 shining black, with a white posterior edge. 



Sahlberg describes the male as having no genital 

 valve, and as being considerably smaller than the female. 



Occasionally taken at Haslemere ; at Shiere, near 

 Guildford ; and at Ash, near Bristol.

This insect may be at once separated from Ulopa by 

 the different forms of the head and pronotum, and like- 

 wise by a variation of the nervures on the elytron.
