SEKEICOKNIA. 171 



Hab. Panama, Bugaba in Chiriqui 800 to 1500 feet (Champion). 



This species resembles H. beltii in form, but is of a more bronzy colour, and has no 

 spots. The thorax has a median impressed line which terminates posteriorly in a 

 shallow fovea ; the punctuation is moderately strong — the punctures on the disc are 

 not very close together, but at the sides they are crowded and coarser. The elytra are 

 moderately strongly punctured in lines, the lines in parts impressed ; there is a very 

 shallow, scarcely perceptible impression at the side below the shoulder, and a second 

 oblique one, rather more noticeable at the side, about the middle ; behind this there 

 is a slight swelling followed by a fairly well-marked impression.
