Philonthus cubensis Bierig, MS. 



Description. — Black (frequently more or less rufescent, especially 

 the pronotum) with brownish pubescence on elytra and abdomen. 

 Head subquadrate, very feebly narrowed behind the eyes to rounded 

 basal angles ; eyes at almost their length from base ; sometimes flattened 

 or impressed in front; with a pair of punctures forming (with two 

 supraocular) a line of four punctures between the eyes; impunctate 

 area of disk smaller than usual; with very fine strigulose ground 

 sculpture, and sometimes greenish lustre. Pronotum one-fourth longer 

 than wide, sides parallel with basal angles broadly rounded ; with two 

 discal series of six punctures, the anterior less distinctly part of the 

 series but distinctly not marginal, and with about four lateral punc- 

 tures; with ground sculpture as on head, lustre more coppery when 

 present. Elytra with surface sometimes subrugose so that punctures 

 are not readily visible ; they are directed posteriorly and more or less 

 submuricate ; shining or with some trace of tuberculate ground sculp- 

 ture. Ahdomen with moderately fine and dense punctures either 

 strongly excavated behind or submuricate ; with more or less distinct 

 ground sculpture. Male., eighth sternite with a rounded or triangular 

 emargination about one-fifth to one-half as deep as wide, with a narrow 

 smooth border, frequently the border emarginately depressed. Female^ 

 eighth sternite rounded or truncate. Length, 4 to 61/2 mm. 



Type locality. — Cuba. Of trepidus, "Americae ins. St. Johannis et 

 Puerto Rico" ; of ohscurtis, Cuba.

 Paris. Of trepidus, either in the Hope Museum, Oxford, or the 

 Zoologische Museum, Berlin ; of obscurus, presumably in the collection 

 of Blanche Rancin, Caen, France.
