324 Mr. A. Murray on Coleoptera from Old Calabar. 



comparatively smaller, and not so broadly margined, and the 

 anterior rounded angles are rather less prominent. The testa- 

 ceous spots on the elytra are much smaller, being limited to 

 small points ; the basal spot scarcely extends beyond the third 

 interstice, although, on close examination, it is seen to encroach 

 a little on each of the adjoining interstices, and the apical spot 

 is almost confined to the third and fourth interstices. 



This may be merely a variety of the preceding. If there had 

 been nothing to distinguish them but the markings on the ely- 

 tra, I should never have thought of separating them ; but the 

 less-margined thorax induces me to keep them separate, at least 

 until a larger series of specimens shall enable us to come to a 

 different conclusion.
