CARABID^E. BEMBIDIUM. 195 



Thorax (PL II. f. 10) shorter, the width greater than the length, 

 the sides much less rounded below the anterior angles and but 

 slightly narrowed behind just before the base, the posterior 

 angles less prominent and smaller, the dorsal furrow very slender, 

 the basal fovea? smoother and the space between them smoother 

 also. Elytra shorter, the shoulders squarer and not narrowed, 

 having the angles only a little obtuse and prominent, sides 

 straighter, apex obtuse, disk finely striated, the striae punctured 

 to behind the middle, then smooth, having two deeper impres- 

 sions between the second and third striae, the interstices smoother 

 and flatter than in flammulatum ; the colour more obscure, with 

 usually two very indistinct reddish testaceous bands, commencing 

 at the outer margin and disappearing entirely before they reach 

 the suture, in frequent examples almost entirely obliterated or 

 interrupted by the darker striae, appearing as merely irregular 

 spots, whilst at the shoulders and at the apex there are occasion- 

 ally also pale spots of irregular shape ; in less frequent examples 

 the whole surface is more testaceous variegated with dusky 

 markings; underside black, with the apex of the abdomen 

 usually concolorous ; legs pitchy testaceous. Length 2 lines. 



In the Linnaean collection examples of this species (mixed up 

 with others of B. flammulatum) stand under the name Carabus 

 ustulatus, Linn. ; Notaphus nebulosus, bifasciatus and obliquus of 

 the Stephensian cabinet must likewise be referred to the same 

 species. 



It is extremely abundant in marshy places and on muddy 

 deposits.

Considerably smaller than ustulatum ; above bronzed, or 

 obscure greenish black. Head small, smooth, depressed in front, 

 and with the usual oblong impression on each side behind the 

 eyes, antennae black, with the underside of the basal joint and 

 the base of the palpi rusty. Thorax subquadrate, short, sides 

 rounded in front below the angles, very little narrowed behind, 

 and with the base still rather wide, the lateral margins finely but 

 distinctly reflexed, the posterior angles right angles, disk finely
