14 TRAVELS AMONGST THE GEE AT ANDES. 



bnisli of short moderately stiff liairs, and the sides of the basal j\)ints have 

 only faint longitu<linal furrows ; the penultimate joint is strongly emarginate, 

 almost liilobed in the anterior pair, and having the outer angles somewhat 

 elongated in the hindmost pair : the claw joint has a few cilia underneath. 

 The metathoracic episterna are short, the outer side about equal in length to 

 the breadth at the base. The elytra are oblong, very slightly narrowing to 

 the nearly rectangular shoulders : the punctures on the third interstice are 

 more than three in number, sometimes as many as seven, the two l>asal ones 

 being on the third stria or in the middle of the third interstice — the others 

 near the second stria.

Long. 1 1 millim. ? . 



Belongs to the C. cejihalotes group by the comparatively short antennaj 

 with joints more ovate than in the typical Colpodes. The metathoracic epi- 

 sterna are short, but the outer side appears a little longer than the width at 

 the Ijase. The head differs much in shape from C. mecjace^jhalus, having a 

 constricted neck as usual in the genu.s, and the sides, instead of forming an 

 elongate tumour behind the eyes, narrowing obliquely and almost in a 

 straight line to the neck, the eyes standing out very prominent. The soles 

 of the tarsi are rather densely clothed with short bristles, the claw joint is 

 naked.
