Geodepliagous Coleoptera of Japan. '237 



example of H. japonicus, which I sent to Baron Chaudoir, 

 was returned by him as " H. rugicollis, Mots., compare 

 a un type." Notwithstanding, therefore, the insuffi- 

 ciency of Motschulsky's description, there is no longer 

 room for doubting that the species formerly determined 

 by me as japonicus is the same as rugicollis.

Appears to be generally distributed throughout Japan. 

 Von Harold had reason in doubting that the species 

 belonged to TachyceUus : on examining the penultimate 

 joint of the labial palpi I find that it is multisetose, like 

 all the true Harpalince, and not bisetose, as in the 

 Stenolophince, to which TachyceUus belongs. It remains 

 to be decided whether the fine oblique impressed line on 

 each side of the forehead, extending from the frontal 

 fovea to the eye, is a character of sufficient importance 

 to separate the species generically from Harpalus. Many 

 of the smaller species of Ophonus present traces of the 

 same character, and in Harpalus Icevicollis, which 

 H. congruus so closely resembles, it appears to be present 

 in some examples and absent in others. 



Harpalus leptopus. 



H. congruo proxime affinis sed major, antennis pedi- 

 busque longioribus. Elongato-oblongo-ovatus, piceus, 

 aenescens vel cuprascens, politus, antennis partibus oris 

 pedibusque testaceo-rufis ; thorace quadrato-cordato, 

 antice rotundato postice longe sinuatim angustato, 

 angulis posticis acutis, margine basali medio recto, versus 

 angulum utrinque retrorsum obliquo, supra punctulato- 

 rugosis disco lsevi, fovea elongata modice impressa ; 

 elytris apice oblique sinuatis, acute striatis, interstitiis
