Eather variable in general colour ; some specimens 

 having ochreons-yellow elytra, whilst others have 

 elytra of a rich chestnut-brown, with dark sienna 

 venations and rounded apices. Limbus small. Head, 

 pronotum and scutellum pale brown, and almost spot- 

 less. Wings purple-grey, with strongly-marked black 

 neuration, the anal vein being much thickened. Legs 

 warm sienna-brown, without spots or streaks. Mr. 

 Edwards notes that the legs are striped and spotted. 

 Abdomen uniformly of a brown-black, and shining. 

 Some specimens show three small dashes on the 

 vertex, and a festooned stripe on the pronotum, and 

 also faint basal spots on the scutellum. 



The pygofer of the male is of a complex, and 

 perhaps unique, nature. The genital valves are large, 

 and produced beyond the apex of the abdomen. The 

 caudal process, the oedeagus, the styles and the lateral 

 processes are singular in appearance when seen in 

 profile ; their details are noted in fig. 3 c. 



My specimens were taken in "Mesopotamia," 

 amongst the marshy land between the Elvers Isis and 

 the Cherwell, at Oxford. The insects seem to affect 

 bogs and damp meadows in early summer.
