Polymorphous as Colpocles is known to be, I place this 

 species in the genus with great reluctance, the 4th tarsal 

 joint being scarcely more emarginate than in many 

 Anchomeni ; it would, however, be still more out of 

 place in any section of Anchomenus. In the long and 

 projecting mandibles and impunctate elytral interstices 

 it agrees with the species of Colpocles formerly included 

 in the genus Pleurosoma, Guerin, but has little general 

 resemblance to them. It has also some affinity to 

 Cyrtolaus, Bates. 



Colpocles amphinomus. 



Agonis majoribus baud dissimilis ; piceo-niger, nitidus, 

 antennis, palpis, thoracis margine laterali pedibusque 

 castaneo-rufis ; capite post oculos convexos gradatim 

 angustato, collo subconstricto ; thorace subovato, postice 

 multo magis quam antice angustato, angulis posticis 

 rotundatis, anticis haud productis, margine laterali sat 

 late explanato-reflexo, intra marginem et in fovea magna 

 basali plus minusve punctato ; elytris ovatis, humeris 

 rotundatis, apice sinuatis, adsuturam obtusis, punctulato- 

 striatis, interstitiis modice convexis, tertio tripunctato, 

 puncto tertio prope apicem. Metathoracis episterna 

 subelongata et angustata. Tarsi posteriores extus tan- 

 tum sulculati ; articulo quarto minime emarginato, ante- 

 riorum sat emarginato, lobis inaequalibus. Long. 8% — 

 10 mm., $ , ? .
