I have not seen Colombian examples of this species. Mexican specimens were 

 named Sericoda corrosa (MS.) by Chaudoir in the Salle collection. They differ slightly 

 from Guatemalan representatives in the less sharply-marked strigose sculpture of the 

 head and thorax. According to Eeiche's description, the sculpture is well marked. 



The species is closely allied to Sericoda bembidioides, Kirby, from North-western 

 America and Canada. In all structural characters Sericoda agrees perfectly with 

 Anchomenus. 



12. Anchomenus dominicensis. 



Oblongus, castaneo-rufus, capite thoraeisque disco plus minusve fuscis, elytris aeneo tinctis, iridescentibus, 

 antennis, palpis, thoracis lateribus pedibusque fulvo-rufis ; palpis subelongatis, artieulo terminali quam 

 prsecedens paullo longiore ; oculis magnis, prominentibus ; thorace transverso, postice paullo magis quam 

 antice angustato, lateribus fortiter arcuatis, angulis anticis rotundatis, posticis distinctis sed obtusis, margine 

 laterali sublate reflexo-explanato, basali fere recto, foveis basalibus magnis subpunctulatis ; elytris apice 

 oblique parum sinuatis, ad suturam conjunctim rotundatis, fortiter striatis, interstitiis subconvexis, tertio 

 tripunctato puncto primo in striam tertiam impresso ; tarsis artieulo quarto simplici, triangulari.

The prominent eyes give this species an appearance different from that of the rest

metallic colour of the elytra, give it the aspect of a Colpodes. The simple penultimate 

 joint in all the tarsi, however, removes it from Colpodes. The ligular structure and the
