El]i2)tic, dull, black. Eli/tra dirty ochreous-browii. 



Head black, finely punctured. A/iteiuue black, the last joint 

 sometimes piceous. Eyes and Ocelli black. Rostrum piceous, 1st 

 joint black. 



Thorax.— Fronotum wider than long, black, sometimes piceous 

 posteriorly, with close, angulated punctures, finer in front than 

 behind ; the callus smooth, piceous. ScuteUum black, punctured, 

 the punctures finer and closer at the base. Eh/tra mostly as long 

 as the abdomen ; Clavus ochreous obscured with brown, with 4 rows 

 of strong, close punctures, the 2 central ones confluent ; Corium 

 dirty ochreous-brown, with darker longitudinal shades ; finely black- 

 punctured in rows ; on the inner nerve a long, thick, black streak, 

 with a shorter pale one joined to its upper end, and a more or less 

 obscure brown spot within the anterior margin ; anterior margin 

 very slightly rounded, clear ochreous, with a brown line on the edge ; 

 posterior margin brown or piceous ; Memlrane crenate, especially 

 on the sides, fuscous ; nerves pale. Sternum black, finely punc- 

 tured. Legs black ; tarsi piceous. 



Abdomen black ; beneath smooth, with fine^ short, yellow pubes- 

 cence. 



Length, S 2^, ? U lines. 



Yar. — The average size rather larger, fvonoium more square, and 

 the punctures stronger ; ehjtra rounder on the anterior margin, 

 giving the insect a more oval form ; the colour deep chestnut or 

 piceous-black. 



This form, first given to us by Mr. E. C. Rye, we at the time 

 accounted a distinct species, which we proposed to call D. Eyeii ; 

 but as Mor and Fieber hold it to be only a variety, we defer to their 

 opinion. Elor says the pale examples have abbreviated wings, which, 

 however, we do not find to be the case. 



In moss, at the roots of grass and under leaves, everywhere, 

 throughout the year ; the var. not so common.
