 out trace of midline; distinctly alutaceous and finely punctulate. 

 Elytra about as wide as pronotum, nearly as long as wide; sides 

 feebly arcuate; surface shining but coriaceous, sparsely, irregularly,

Types.— Roloiy^Q (M.C.Z. No. 20237) and one paratype in the 

 Museum of Comparative Zoology. 



Records. — The following are the records known to me : 



Hispaniola: Haiti, Massif de la Hotte (Darlington, 1937), Tardieu (Darlington, 

 1937). 



Specimens exami?icd. — I have seen only the paratype from the 

 Museum of Comparative Zoology. 



Reinarks. — The clypeus in this species is rather asymmetrical but 

 is quite distinctive. The description is based upon the paratype. 



I find no record of the habits of this species.
