CARAB1DJE. DYSCHIRIUS. 27 



narrowed below the anterior angles ; thence evidently dilated 

 about the middle and somewhat rounded, but again narrowed 

 behind ; disk very convex, with a deep central line bordered by 

 numerous wrinkles and met in front by a transverse oblique 

 stria, which also is wrinkled or striated below. Elytra wider 

 than the thorax, elongate-ovate, having the shoulders rather 

 elevated, very convex, strongly striated, especially at the base 

 and next the suture, the stride distinctly punctured except at the 

 extremity, the marginal stria abbreviated at the shoulder, the 

 first and second next the suture carried almost to the apex, the 

 third and fourth unite before the apex, the fifth and sixth also 

 unite, the seventh and eighth are carried round the margin to 

 the extremity of the suture, where they unite and form a strongly 

 impressed loop (PL I. f. 10) : the underside of the body is 

 brownish black, the legs pitchy red, thighs somewhat brassy, 

 anterior tibiae stout and furnished with two strong spines at the 

 extremity of equal length, and a smaller one near the notch, 

 being armed likewise externally with two obtuse teeth. Length 

 2 lines. 



This species, the largest of our indigenous Dyschirii, is not 

 very common. Mr. Stephens gives as its localities the shores 

 of the Thames and Humber, but I suspect that examples of 

 salinus, a species not uncommon in those localities, have been 

 mistaken for it. It is found on the Norfolk and Lincolnshire 

 coasts, near Liverpool, &c.

Elongate, subparallel, rather narrowed towards the extremity, 

 brassy and shining ; mouth, mandibles, base of the palpi and of 

 the antennae rusty red. Thorax oblong-ovate, with the sides 

 more rounded in some examples than in others, and usually 

 more dilated and straight in the ? than in the <$. Elytra 

 broad and somewhat elevated at the shoulders, sides not quite 

 parallel but gradually decreasing in width (PL I. f. 11), punc- 

 tate-striated, the stria? most impressed at the base and next the 

 suture and continued to the extremity, except the third and
