ated in the plate by an unfortunate twist in the specimen) and with strife 

 almost wholly made up of tolerably heavy circular punctures, which fade 

 out on the apical half of the elytron and are obsolescent on the sides. It 

 is about as heavily marked as B constrictum. 



Length of fragment, 3.C mm ; probable length of elytron, 4 mm ; its 

 breadth, 1 45 mm .

A nearly perfect elytron with the humeral angle broken off represents 

 a carabid, probably related to Nebria. A species is indicated which is of 

 about the size of N. sahlbergi Fisch. The elytron is about two and a half 

 times longer than broad ; the surface is nearly smooth, piceous, with nine 

 stria3, which are rather deeply impressed, and a scutellar stria, which unites 

 with the first longitudinal stria at about one-sixth the distance from the 

 base, in such a way as to make it appear equally forked in passing toward 

 the base, its outer fork striking close to the base of the second longitudinal 

 stria ; the fifth and sixth stria? are united to each other and to the united 

 third and fourth striae, near the apex, by a wavy continuation of the sixth, 

 after it lias bent toward the fifth in running parallel to the seventh, as it 

 curves toward and runs to the tip of the elytron ; the ninth stria, which 

 forms the edge of the elytron as it is preserved, shows no appearance what- 

 ever of ocellate punctures, although under the microscope some of the 

 central striae show slight signs of faintly indicated punctures near the 

 middle of the elytron. 



Length of elytron, 5.2 mm ; breadth, 1.8 mm .
