 fuscous towards apex ; head striated between eyes ; thorax conical, closely 

 and rather coarsely punctured, with a distinct furrow before scutellum ; 

 elytra oval, with shoulders rather strongly marked, and with punctured

Male with the scape of the antennae clavate, much dilated at apex, 

 funiculus with the first joint small, and the second and third very broad 

 and dilated ; femora, except extreme apex, the trochanters, and more or

Marshy places ; on Polygonum hydropiper, &c. ; local ; London district, rather 

 common and generally distributed ; Birchington ; Deal ; Dover ; Hastings ; Arundel ; 

 Brighton; Portsmouth; Devonshire; Littlington, Cambridge; Huntingdonshire;

 apex, and anterior coxae, red ; anterior tibia? mostly red, intermediate 

 and posterior pairs with a broader or narrower red ring before base ; the
