lowing particulars. It is black instead of virescent fuscous. 

 The head is wholly impunctate ; the angular depressions in front 

 are shallow, and united by a faint transverse line instead of a 

 deep groove, and the epistome has scarcely any depression. The 

 thorax is impunctate on the disk; the dorsal line is scarcely 

 punctate, and it reaches wholly to the front, the posterior angles 

 are less obtuse than in D. Dohrnii, and somewhat sinuate, so as at 

 the very point to be almost right-angled for a short space. The 

 elytra are more deeply striate, and the interstices more convex 

 and impunctate. The under side has scarcely any punctation 

 at all, either on the sides or middle. In other respects the same 

 description will apply to the two species. 



I have named this species after my friend Mr. Frederick Smith 

 of the British Museum, whose kindness places the extensive in- 

 formation he possesses at the disposal of all who desire to profit 

 by it.

1. O. rugicepSy mihi. 



Latus, depressus, niger, subnitidus; antennis, palpis, abdomine 

 tarsisque piceis ; capite punctato-rugoso, bi-impresso ; thorace 

 leviter et sparsim trans versim rugoso, interstitiis levissime et 

 perparce punctato, sine punctis majoribus in rugis; elytris 

 lepidissime et subtilissime transversim aciculatis, striato-punc- 

 tatis, interstitiis parum convexis, hie et illic leviter punctatis ; 

 subtus subopacus ; abdomine subtiliter aciculato, praecipue" 

 lateribus. 



Long. 8 lin., lat. 3J lin. 



Depressed, broad, black, with something of a silky gloss. 

 Head rugosely punctate, with two longitudinal depressions be- 

 tween the antennae united by a transverse line ; antennae, palpi, 

 and parts of the mouth piceous. Thorax transversely rugose, 

 lightly and sparsely on the disk, more coarsely on the depressed 

 sides and base, the spaces between the rugosities on the disk 

 faintly and sparingly punctate, no larger punctures in the rugae; 



* Notwithstanding the high authority of M. Lacordaire, to which I have 

 deferred for the sake of uniformity, I cannot bring myself to think that 

 this is the proper position of this genus. Sometimes trifling distinctions, 

 which are yet found constant in a group, help one to discover the true 

 affinities of a species when more prominent characters fail. In this instance 

 the pectination of the claws of the tarsi, the acicular microscopic sculpture 

 on the elytra, along with their truncation, lead me to look for the proper 

 place of the genus in the neighbourhood of Calathus, Pristonychus, &c, 

 in which exactlv the same characters are found.
