78 CARABID^E. CALATHUS. 



the margins of the elytra narrowly red. Head black, depressed 

 in front, palpi and antennae testaceous. Thorax subquadrate, 

 shorter and broader than in the preceding species or either of 

 the following, distinctly contracted in front, the sides parallel 

 from the middle to the base, which is truncate, and the posterior 

 angles obtuse, the dorsal line slender, terminating before and 

 behind in a depressed space, the disk on each side of it finely 

 wrinkled transversely, the base furnished with a shallow impres- 

 sion on each side more or less slightly evident. Elytra a little 

 wider than the base of the thorax, ovate, apex rounded, finely 

 striated, having two impressions between the second and third 

 striae ; legs testaceous red. Length 3 lines. 



There are varieties in which the thorax is more or less pitchy. 

 C. apicalis, Newman, is an immature example of this species, 

 which is very common everywhere.

Wingless, black (or pitchy black), very shining ; mandibles, 

 palpi, antennae and legs (and sometimes the lateral margins of 

 the thorax narrowly) testaceous red. Head convex, smooth and 

 shining, with a fovea on each side in front between the antennas 

 and a slight double impression on the crown, the fifth to the last 

 joints of the antennae rather stout. Thorax subquadrate, rather 

 narrowed in front and rounded below the anterior angles, 

 slightly narrowed also behind, with the margins slenderly 

 reflexed and the posterior angles obtuse, disk convex, the central 

 line deep at the base, and a deeply impressed roundish fovea on 

 each side near the hinder angles which are otherwise slightly 

 rugose. Elytra oblong-ovate, shoulders rounded and a little 

 narrowed, sides very slightly rounded, disk convex, finely stri- 

 ated, some of the stria? very obsoletely punctured, the third 

 with three deeper impressions near* one another before the
