out order, with the interstices deeply alutaceous, with a long deep 

 transverse fovea on each side of the thorax extending from the posterior 

 angle nearly to the scutellum ; antennje piceous ; the basal joints of all 

 the tarsi enlarged in the male. 



Head moderate, rather prominent, with the eyes moderate and promi- 

 nent ; antennae long, piceous, with the basal joints paler. 



Thorax rather longer and wider than the head, with the sides dilated, 

 rounded, and rather contracted at the base, thickly covered with 

 minute tubercles, with the interstices deeply alutaceous ; the pos- 

 terior margin strongly sinuated, with the angles considerably pro- 

 duced and acute, with a long deep transverse fovea on each side, 

 gradually increasing in width from the scutellum to the hinder 

 angle. 



Scutelltmi large, triangular, deeply asperate, with the interstices aluta- 

 ceous. 



Elytra ovate, not wider than the thorax, about as long as the head and 

 thorax united, with the sides rounded, deeply and irregularly as- 

 perate, much contracted and deflexed towards the apex, with the 

 apex straight and narrowly pale. 



Abdomen considerably exposed. 



Legs long, yellow, with the basal joints of all the tarsi dilated in the 

 male ; in the anterior pair the basal joint is very short and wide, 

 the second is immensely dilated and unequally bifid ; on the in- 

 terior edge it is fringed with a row of strong, incurved, and very 

 long setsB, equal in length to the whole of tlie third joint, which is 

 simple ; in the four posterior tarsi the basal joints are enlarged 

 rather than dilated. 



Underparts black, with the mouth, apex of the abdomen, and coxae 

 yellow, and the thighs dusky. 



This species may be known by its ovate and posteriorly contracted 

 shape, long piceous antennae, the sculpture and the fovese at the pos- 

 terior angles of the thorax, and by the peculiar formation of the an- 

 terior tarsi in the male. 



Two specimens, male and female, were taken by myself under damp 

 litter in the Norfolk Marshes, in April, 1863.
