344 Mr. M. Cameron on new Staphylinidse 



33. Ophiomedon anthr acinus, sp. n. 

 (Fauvel., in litt.) 



Entirely black, dull. Antennae blacky with the apex of 

 last joint yellowish. Legs dark brown. 



Length 5'5-6'3 mm. 



Head square, as broad as the elytra, truncate posteriorly ; 

 eyes small, their diameter much less than the length of the 

 temples, which are long and parallel ; posterior angles right 

 angles, only blunted at the extreme apex ; mouth-parts 

 brown. Antenna; long, rather slender, pilose; first joint 

 stout, elongate ; second much shorter than first and third ; 

 third much shorter than first ; fourth to tenth longer than 

 broad, gradually decreasing in length ; eleventh oval, pointed, 

 longer than tenth ; puncturation close, umbilicate, not very 

 coarse. Thorax scarcely longer than broad, widest at the 

 anterior angles, which are obtuse, gradually narrowed poste- 

 riorly in a straight line. Puncturation similar to, but rather 

 finer than, that of the head ; disc with a fine channel poste- 

 riorly. Elytra distinctly longer than the thorax, longer 

 than broad, pretty closely and finely punctured. Abdomeu 

 closely and finely punctured. 



<^. Last ventral plate with a deep triangular excision ; 

 the penultimate rather deeply and broadly emarginate, the 

 base of the em argi nation rounded, the angles produced a 

 little backwards, and, together with the sides of the notch, 

 turned and folded to form on either side a spoon-shaped 

 structure with the concavity iirwards. 



St. Vincent {H. H. Smith). Type in the British Museum. 



34. Medon cinyulatus, sp. n. 



(Fauvel, in litt.) 



Pitch-brown or pitch-black, dull ; apical third or half of 

 the elytra, apex of abdomen, antenuoe, and legs reddish 

 testaceous. Tarsi simple. 



Length 3*5 mm. 



Size and build of L. infuscatuSj readily distinguished by 

 the much smaller eyes, the rectangular posterior angles of 

 the head (which, with the thorax, is much more finely punc- 

 tured), and the coloration of the elytra. 



Head large, square, as broad as the thorax ; eyes moderate ; 

 temples considerably longer than their diameter ; base 

 truncate, posterior angles rectangular; sculpture coriaceous, 

 w i 1 1 i very fine, obsolete, scattered punctures; sides with
