350 On new Staphylinidse from the West Indies. 



Micranops, gen. nov. 



Body elongate, apterous. Head oval-oblong, a little 

 broader than the thorax, longer than broad, emar^inate 

 posteriorly, the neck about one-third the breadth of the head. 

 Eyes wanting, their position marked by a small, round, 

 whitish depression. Labrum transverse, bidentate, the teeth 

 separated by a narrow triangular notch, setose. Mandibles 

 falciform, with three blunt teeth about the middle. Maxillae 

 with the inner lobe ciliate internally, the outer ciliate at 

 apex. Maxillary palpi of normal length ; first joint very 

 small ; second elongate, about the length of third, the latter 

 thickened towards the apex ; fourth minute, subulate. 

 Labium transverse. Tongue small, acuminate; paraglossae 

 of similar size and shape. Labial palpi with first and second 

 joints cylindrical ; second a little longer than first ; third 

 slender, pointed. Gular sutures diverging in front and 

 behind, most approximate about the middle. Antennas 

 filiform, straight. Thorax oblong, as wide as the elytra, with 

 the angles rounded. Scutellum small, triangular. Elytra 

 shorter than the thorax, transverse. Abdomen bordered, 

 slightly widened before the apex, seventh dorsal segment 

 without a membrane at the posterior border ; first ventral 

 plate furnished with a short keel at the base ; anal styles not 

 exposed. Legs rather short, thighs stout, anterior tibiae 

 excavate internally. Tarsi five-jointed, the anterior (at least 

 in $ ) dilated, middle and posterior short, simple ; the first 

 four joints subequal, fifth shorter than the first four united; 

 claws simple. Tibiae pubescent. 



Stands near Lathrobium and. Scopceus ; from the first it 

 differs in the bidentate labrum, the tridentate mandibles, 

 pointed ligula, and structure of the posterior tarsi ; from 

 Scopceus it differs by the bidentate labrum, simple ligula, and 

 stout neck, but agrees with it in the structure of the poste- 

 rior tarsi. It has the facies of a minute Lathrobium. 



42. Micranops brumieus, sp. n. 



Dark chestnut-brown, scarcely shining ; head and thorax 

 strongly coriaceous, with superficial scattered puncturation ; 

 mouth-parts, antennae, and legs testaceous. 



Length 2 3 mm. 



Head oval-oblong, longer than broad, emarginate poste- 

 riorly, posterior angles rounded. Eyes absent, their position 

 marked by a round whitish depression. Antenuae testaceous ; 

 first joint stout, not quite so long as the three following
