Panama, Volcan de 





Chiriqui (Champion). 



An aberrant species, much resembling Cyrtolaus lobipennis, but presenting 



...... 



generic characters of Colpodes. The mandibles are similar in their length 

 straightness to Cyrtolaus, but the ligula is of the normal Anchomenid form, and the 



i 



four hind tarsi are slender, with the usual lateral groove (situated nearer the

surface than usual) on each side of the joints, the 4th joint having the usual long 



■ 



narrow lobes (the exterior the longer) of Colpodes. The metathoracic episterna, thoug 

 short, have not the broad form characteristic of the first section, but are considerably 

 narrowed behind.

This is another aberrant species, unlike any other member of the genus both in 







general form and in the combination of structural characters. The metathoracic 

 episterna have nearly the same form as in C. prostomis ; and the tarsi are similarly 



■ 



grooved, but the fourth joint is simply emarginate, with moderately produced angles.

4. Colpodes pterostichoides. (Tab. V. fig. 4.) 



Oblongus, depressus, cupreo-piceus, antennis, palpis pedibusque rufo-piceis ; oculis parvis, collo crasso ; thorace 

 quadrato, ante medium modice angustato, angulis antieis productis, post medium fortiter sinuato sed 

 parum angustato, angulis posticis acutis productis, supra lsevi ; elytris breviter oblongis, humeris subrectis, 

 apice sat fortiter sinuatis, subtiliter sed acute striatis, interstitiis planis tertio 3-punctato ; metathoracis 

 episternis brevibus ; tarsis posticis utrinque sulcatis, articulo 4° lato profunde emarginato ; plantis omnibus 

 dense pubescentibus, articulo unguiculari nudo. 



Long. 5i lin.

Unlike any other Colpodes known to me, and in general form similar to the 



■ 



Pterostichi allied to P. midtipunctatus. The elytra are more metallic than the rest of 



the surface, dark purplish coppery, with a slight opalescent lustre.
