 angles blunt; elytra somewhat wider than in the species of the following 

 genus, testaceous, feebly striated, with two oblique streaks on each side 

 of scutellum, and the suture itself until middle where it dilates into 

 a lozenge-shaped spot, dark ; there are also two dark spots near the 

 margins behind niidtile, usually connected with the middle spot by two 

 lines, the whole markings bearing a fancied resemblance to the double-

DEIVIETIIIAS, Gondii. 



This genus comprises about eight species mostly from Europe and 

 Northern Asia ; they are distinguished from the preceding Ijy having tlie 

 tarsal claws pectinate or denticidate, the paraglossae only reaching slightly 

 beyond the lingua, and by the emargination of the mentum being fur- 

 nished with a simple tooth ; from Dromius they are at once separated, 

 like the preceding, by the strongly bilobed penultimate joint of the 

 tarsi. 



1. Elj'tra with a common well-marked spot on apical

2. Elytra with suture more or less dark, but with no

 form, slightly margined, posterior angles very blunt ; elytra testaceous 

 with suture and a common spot black, feebly striated, third interstice 

 with two pores; underside and legs testaceous. L. 4-4 1 mm. 



At roots of grass, in moss, &c., also on rushes, on sand-hills, and in dry sandy
