This is a small and somewhat elongate species without a 

 trace of metallic lustre. It was found in rotten wood.

Habitat. St. Vincent. 



This insect was found in fungi. It may be at once 

 distinguished from the previous one by the broad scutellum, 

 the deeper emargination of the clypeus, the much longer 

 first joint of the hind tarsi, etc. It is closely related to 

 the Amazonian Pseudoserica longitarsis of Bates, although 

 differing from it in numerous points of detail. 



Although congeneric with the latter, I have preferred to 

 use the generic name Plectris for these two insects as, 

 even if Bates' attempt to divide that genus should prove 

 adequate upon consideration of the whole mass of known 

 species, which there seems reason to doubt, his adoj)tion of 

 the old name Pseudoserica is, I believe, due to an error, for 

 the insect which I regard as the true Pseudoserica marviorea, 

 Guerin, represents a peculiar genus exhibiting none of the 

 characteristics cited by Bates.
