MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 417 



Remarks.— T\\\^ species is quite similar to what I recognize as 

 havaniensis but is apparently distinguishable by the shape of the 

 pronotum. It is distinguished from laaterhousei and most other 

 species by the greenish color of the elytra. Dr. Cameron described 

 this species as "very black." Examples of waferhousei that he de- 

 scribes as "black'' are generally slightly castaneous or rufescent. It 

 is assumed that this species is actually black and not picescent. 



I find no record of its habits. 



12. PHILONTHUS WATERHOUSEI Cameron 



Philonthm waterhousei Cameron, 1922, p. 120.— Scheerpeltz, 1933, p. 1369. 



Description. — Piceous, generally feebly rufescent. Head transverse, 

 somewhat narrowed behind eyes, the latter at distinctly more than 

 their length from base ; basal angles rounded ; with a slight depression 

 in front; disk with two punctures forming (with two supraocular) a 

 line of four between the eyes, and with scattered punctures at sides 

 and base leaving only the center of vertex impunctate; without dis- 

 tinct ground sculpture. Pronotum about one-third longer than wide, 

 widest at anterior third, feebly emarginately narrowed to basal third, 

 with basal angles broadly rounded ; with two discal series of five punc- 

 tures, fairly evenly spaced, and with about seven lateral punctures; 

 with vague ground sculpture. Elytra with moderate punctures sep- 

 arated by about their diameter ; the surface even and without ground 

 sculpture. Abdomen rather irregularly but finely and submuricately 

 punctured; with traces of ground sculpture. Male., eighth sternite 

 with posterior margin sinuate but not distinctly emarginate, bordered 

 at center with a narrow smooth rim. Female., eighth sternite 

 rounded. Length, 4 to 5 mm. 



Type locality. — St. Vincent, Leeward side. 



Types. — In the British Museum; one "cotype" in Dr. Cameron's 

 collection, six "cotypes" in the United States National Museum (No. 

 50878). 



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



St. Vincent: (Camei'ou, 1922; British Museum; Cameron collection; U.S.N.M.). 

 Grenada: (British Museum; Cameron collection; Cameron, 1922; U.S.N.M.). 



Specimens examined. — I have seen 12 examples in the British Mu- 

 seum, 7 in Dr. Cameron's collection, and 6 in the United States 

 National Museum (each including the types mentioned above). 



Remarks. — This species is distinguished by the characters given in 

 the key and by the very feeble characters of the male. The descrip- 

 tion is drawn from a St. Vincent example in the United States 

 National Museum. 



I find no record of its habits.
