with strong umbilicate punctures as on vertex ; labrum transverse with 

 a broad median anterior lobe. Pronotum with punctures obsolescent, 

 not distinctly umbilicate; with only a feeble flat midline; no gi'ound 

 sculpture; lateral impressions moderate but distinct. Elytra slightly 

 shorter than long; sides evenly arcuate, not expanded posteriorly; 

 with moderately coarse and distinct punctures, generally separated by 

 less tlian their diameter by rather flat intervals. Ahdomen very finely 

 and not distinctly submuricately punctate. Male^ eighth sternite with 

 a shallow emargination. Female^ sternites not modified. Length, 

 21/2 to 31/2 mm. 



Type locality. — Grenada, Balthazar. 



Types. — Twelve examples (one labeled type) in the British Mu- 

 seum). 



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



St. Vincent: (Cameron, 1913; Leng and Miitchler, 1917). 

 Grenada: (Cameron, 1913; Leng and Mutchler, 1917). 



Specimens examined. — I have seen 56 examples (including the type) 

 in the British Museum and 6 in the collection of Dr. Cameron. One 

 example was borrowed from the British Museum for further study. 



Rcmarhs. — This species seems to be distinct from the others of our 

 region by the strength of the umbilicate punctures of the head. It 

 is also distinct in coloration. 



I find no record of its habits.
