 LINGTON, 1937, pp. 287, 299, 300. 



Description. — Black, elytra rufopiceous mediobasally. Head 

 about seven-eighths as wide as pronotum; eyes a little prominent; 

 clypeiis broadly emarginate in front, angles prominent; labrum 

 scarcely emarginate, even above declivity, alutaceous; antennae slen- 

 der; with moderately large but not very sparse punctures obscured 

 by very strongly and densely alutaceous ground sculpture. Prono- 

 tum about one-seventh wider than long, moderately narrowed pos- 

 teriorly, base three-fourths as wide as apex ; sides scarcely but evenly 

 arcuate ; hind angles feebly rounded ; lateral margins not enlarged pos- 

 teriorly; without midline except as impunctate band; with very 

 coarse punctures, generally separated by less than twice their diam- 

 eter; alutaceous. Elytra as wide as pronotum, a little longer than 

 wide; sides nearly straight; coriaceous, but with large punctures 

 more or less serial, and moderately distinct alutaceous ground sculp- 

 ture. Abdomen alutaceous; with submuricate punctures. Anterior 

 face of front tihia with a few scattered setigerous punctures. Length, 

 5 mm. 



Type locality. — Cuba, Cayamas, about 15 miles west-northwest of 

 Cienfuegos, province of Santa Clara. 



Types. — Holotype and two paratypes in the United States Na- 

 tional Museum (No. 26334) ; one paratype in the collection of How- 

 ard Notman; one paratype in the Museum of Comparative Zoology. 



Records. — The following is the only record known to me: 



Cuba: Cayamas (Notman, 1925; Darlington, 1937; U.S.N.M.). 



Specimens examined. — I have examined the three types in the 

 United States National Museum. 



Remarks. — This species has not been reported since its description. 

 It is rather feebly differentiated from haitiellus and minor, 



I find no record of its habits.
