 nual, p. 33. 



O. rotundicollis, Steph. Mand. 5. 376, et Manual, p. 33. 



Shining black, apex of the antennae and of the palpi testaceous, 

 and the base of some of the joints pitchy red. Thorax sub- 

 quadrate, a little narrowed behind, the sides acutely margined, 

 the hinder angles right angles and a little prominent, the base 

 with a very large rugose fovea on each side terminating as usual 

 in two striae. Elytra rather parallel, striated, the striae obsoletely 

 punctured, with three deeper impressions on the third interstice, 

 two of them near the second stria and one near the third ; abdo- 

 men beneath smooth in both sexes, the rudiments only of a 

 raised line being discernible under a magnifying glass on the 

 last segment, each segment having two punctures placed equi- 

 distant from each other so as to form two parallel lines of 

 punctures; legs pitchy red, middle of the femora darkest. 

 Length 4 lines. 



The species is not common ; Mr. Haliday captured it near 

 Belfast. I have taken it in the marshes near Whittlesea Mere and 

 at Herringstone near Dorchester in May and June, and in Ham- 

 mersmith marshes, not unfrequently among refuse or under 

 stones. The examples in the Stephensian cabinet which stand 

 under the name rotundicollis belong to this species, and are stated 

 to have been captured near London.

Winged, black or pitchy black, mouth, palpi and antennae 

 pitchy red, base of the latter dusky ferruginous. Thorax sub- 

 quadrate, sometimes entirely quadrate, rather narrowed behind, 

 posterior angles right angles, the dorsal furrow more deeply im- 

 pressed before and behind, the base with two foveae much punc- 

 tulated, the space between them being in some examples smooth, 

 in others very much punctured, and the size of the foveae varies
