MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 303 



Remarks. — The above description of the male characters differs from 

 Dr. Cameron's description in the structure of the seventh sternite. 

 It was taken from one of the original series borrowed from the British 

 Museum. The species is apparently even more distinct from jueuiidits 

 than was previously thought. 



I find no record of its habits. 



4. RUGILUS CUPREUS (Cameron) 



Stilicus cupreus Cameron, 1913b, p. 341. — Leno and Mutciileb, 1917, p. 198. — 



SCHEERPELTZ, 1933, p. 1241. 



Description. — Bronze-black with coppery lustre, elytra brown, shin- 

 ing. Head transverse, posterior angles rounded, as wide as elytra; 

 punctation close, umbilicate, with a small smooth space on vertex. 

 Pronotum- trapezoidal, scarcely longer than width at anterior angles ; 

 gradually narrowed in a straight line to base, more strongly narrowed 

 in front ; disk with smooth median line ; punctation as on head. Elytra 

 distinctly longer than pronotum, longer than broad ; with moderately 

 coarse and rugulose punctation. Abdomen closely and finely punc- 

 tured. MaJe, unknov.n. Female., sternites not modified. Length, 

 41^ mm. (From Cameron.) 



Type locality. — Jamaica, Newcastle district, elevation 3,000 feet. 



Types. — Unique type (female) in the collection of Dr. Cameron. 



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



Jamaica: (Leng aud Mufchler, 1937), Newcastle (Cameroii, 1913), Blue Mountains 

 (Darlington, in M.C.Z). 



Specimens examined. — I have seen only the type, which I examined 

 briefly in Dr. Cameron's collection, and the specimen mentioned below. 



Remarks. — An example taken by Dr. Darlington in 1934 close to the 

 type locality has not been compared with the type but appears to be 

 this species. It shows the following additional characters: Outer 

 apical corner of elytra indefinitely paler; head scarcely measurably 

 broader than long ; eyes at about thoir length from base ; labrum with 

 two small median denticles, none lateral; pronotum one-tenth longer 

 than wide, seven-eighths as wide as head; with indistinct shiny area 

 on each side ; elytra as long as broad, two-fifths wider than pronotum 

 and two-sevenths longer; punctures indistinct and mixed with flat 

 tuberculi, all obscured by rugulose surface; male, seventh sternite 

 with a semicircular emargination almost as deep as wide, the angles 

 right; eighth with a more open emargination of same size, one-half 

 wider than deep. Length, 4 mm. 



The key characters wei-e taken from this specimen since the type is 

 not available for further study. It is distinct by its elytral sculpture 

 as well as by the male characters. 



I find no record of its habits.
