UsiLANUS, gen. nov. 



Head somewhat long, subtriaugular, about or almost as 

 long as the anterior lobe of the pronotum, the central lobe 

 distinctly produced and projecting in front, ocelli near base, 

 much nearer to eyes than to each other ; antennfe with the 

 first joint moderately thickened, shorter than head but passing 

 its apex, second, third, and fourth joints almost subequal in 

 length ; rostrum reaching the intermediate coxae, first joint 

 slightly passing the base of head, second not reaching the 

 base of prosternum ; pronotum shorter than breadth at base, 

 the lateral margins obliquely rounded, transversely impressed 

 behind middle, the anterior margin scarcely or only slightly 

 broader than the eyes, the anterior lobe subglobose, the basal 

 area or posterior lobe coarsely punctate, faintly, centrally, 

 longitudinally ridged, and here the lateral margins are a little 

 laminate, posterior margin distinctly concave before scutellum, 

 the anterior margin truncate ; scutelhim triangular, slightly 

 longer than broad at base; clavus longitudinally punctate, 

 corium with the subcostal vein distinctly curved; membrane 

 slightly passing the abdominal apex, with four longitudinal 

 veins, the two inner strongly curved towards base and 

 reaching basal margin, the two outer not reaching basal 

 margin ; anterior femora incrassate and somewhat con- 

 tinuously but irregularly spined beneath, anterior tibiae a 

 little curved, somewhat flattened and also shortly spined 

 beneath on their apical halves, intermediate and posterior 

 legs moderately slender, the tibiae setose, first joint of the 

 posterior tarsi about one and a half times as long as the 

 remaining joints together. 



Allied to the genus Eremocoris.

Body above black, lateral margins of the corium narrowly 

 ochraceous ; antennas piceous, about its basal iialf pale ochra- 

 ceous ; head beneath and sternum black, abdomen piceous ; 

 rostrum pale ochraceous, the basal joint black ; legs pale 

 ochraceous, the anterior femora, apices of intermediate and 

 posterior femora, apices of all the tibiae, and apices of the 

 anterior tarsal joints black ; head somewhat coarsely punc- 

 tate on basal area; pronotum finely and sparsely punctate on 

 the smooth anterior subconvex lobe, more coarsely so near 

 the anterior mar-gin, posterior lobe thickly coarsely punctate;
