has the clypeus almost smooth and its front margin strongly 

 reflexed and feebly excised. Burmeister^s description of his 

 S. saucivs exactly applies to the Fabrician species, and the 

 localities also agree, the Copenhagen type being labelled 

 " Essequibo." 



Ligyrus maximus^ sp. n, 



Niger, nitidus, subtus piceo-rufus, eloiigatus ; capita toto trans- 

 verse rugato, antice angustato, acute bidentato, sutura clypeali 

 obsoleta, tuberculis duobus sat remotis indicata ; pronoto convexo, 

 crebre baud grosse punctate, postice parcius, margine antico 

 medio acute tuberculato et post tuberciilum sat late et profunde 

 excavato, marginibus lateralibus regulariter valde arcuatis, antice 

 contractis ; scutello laevi ; elytris ubique crebre sat minute punc- 

 talis, lineis gemiuatis tribus inconspicuis discoidalibus ; pygidio 

 minute et crebre punctato, apice fere laevi ; corpore subtus

This is very near L. maimon, Er., and latifovea, Bates, but 

 is larger than these and all other known species of the genus ; 

 the pronotum is more strongly and closely punctured, the 

 anterior fovea deeper and broader, and the pygidium more 

 strongly sculptured.
