strigulose ground sculpture. Pronotum almost one-half longer than 

 wide, widest at anterior angles, sides feebly converging behind and 

 very feebly emarginate, base broadly rounded, angles traceable ; dorsal 

 series with 9 or 10 punctures, and with scattered lateral punctures; 

 with very feeble strigulose ground sculpture. Elytra with irregular 

 punctures not very coarse or dense, somewhat serial at sides; surface 

 very uneven but without ground sculpture. Abdomen with sparse 

 fine umbilicate punctures and feeble transverse strigulose ground 

 sculpture. Length, 6iA mm. 



Tyj)e locality. — Cuba, Soledad near Cienfuegos. 



Types. — Holotype in the Museum of Comparative Zoology, col- 

 lected in April 1936 by Dr. P. J. Darlington. 



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



Cuba: Soledad (Darlington, in M.C.Z.). 



Specimens examined. — I have seen only the holotype. 



Remmrks. — This species is only feebly distinguished from jamai- 

 censis as outlined in the key. Additional differences are the emargina- 

 tion of the pronotum and the serial arrangement of certain elytral 

 punctures. 



I have received no record of its habits.

Description. — Black, elytra testaceous, abdomen more or less piceous 

 or castaneous. Head only one twenty-fourth longer than wide, 

 scarcely enlarged posteriorly, basal angles marked by ridges; antennal 

 grooves feeble, but with an additional pair of antennal grooves di- 

 rected diagonally backward from the base of antennae; ocular 

 grooves absent ; without definite punctures except for scattered setiger- 

 ous punctures and minute punctulae, but with coarse longitudinal 

 scratches throughout, above and beneath. Pronotum one-fifth longer 

 than wide, widest at anterior angles which are rounded, thence evenly 

 narrowed to broadly rounded base; with a few large setigerous punc- 

 tures and the minute punctulae. Elytra very coarsely but not densely 

 punctate, the punctures more or less serial but not evenly arranged. 

 Abdomen with rather sparse setigerous punctures and indistinct 

 transverse strigulae. Length, 7 to 10 mm.
