Desc7'iptio7i. — Black or piceoiis. Head with large, scattered, some- 

 what umbilicate punctures and a few minute punctulae; with dense 

 reticulate ground sculpture except in front. Pronotum with punctures 

 a little smaller than on head, somewhat obscured by very dense reticu- 

 late ground sculpture but often separated by their diameter ; without 

 distinct midline. Elytra with deep and strong punctures as large 

 as those on head separated by their diameter or less by feebly convex 

 intervals; without distinct ground sculpture. Abdomen with mod- 

 erately coarse excavated or submuricate punctures; ground sculpture 

 indistinct except in punctures. MoJe^ eighth sternite somewhat trian- 

 gularly produced. Female^ eighth sternite rounded. Length, 9 to 

 11 mm. 



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

 fuegos, province of Santa Clara. 



Types.— Ro\Qiy\)Q, female, U.S.N.M. No. 52474, collected by E. A. 

 Schwarz; one paratype from Soledad, Cuba, in the Museum of Com- 

 parative Zoology ; 16 paratypes from the Cayman Islands in the Oxford 

 University collection and 7 in the United States National Museum, 

 collected by Dr. C. B. Lewis. 



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



Cuba: Cayamas (Schwarz, in U.S.N.M.), Soledad (Darlington, in M.C.Z.). 

 Caymans: Grand Cayman (LeAvis, in Oxford University and U.S.N.M.). 



SpechneTis examined. — I have seen only the 25 types. 



Remarks. — This species is similar only to insigniventris which is not 

 available for comparisons. If differs from all other West Indian 

 Finophilus in the dense reticulate ground sculpture.
