Description. — Length 15-18 mm. Mandibles sometimes withont ridge between 

 upper tooth and first terminal tooth ; otherwise as in L. hicolor. Head proportionally 

 broader than in that species, with inner tubercles more widely separated from outer 

 tubercles and from anterior angles ; keels of parietal ridges less overhanging. Prono- 

 tum very much flattened, with deeply impressed median groove; very sparsely punc- 

 tured at sides, punctures usually thickening a little in anterior angles ; prothorax beneath, 

 scntellum and mesothoracic epistcrna as in all preceding species of the genus ; mesa- 

 stermim as in L. anipunctus, the horizontal central area occasionally marked with 

 obscure fine punctures. Metastemum entirely unpunctured, often more or less 

 roughened in lateral and anterior intermediate areas, more rarely in posterior 

 intermediate areas also; lateral areas linear, not in contact with central area. 

 Posterior parts of hind coxae never altogether smooth and polished, mostly rough. 

 Abdominal sterna with usual aiiterior marginal band and lateral patches of punctures 

 of variable extent ; terminal sternum smooth or more or less covered with more or 

 less indistinct punctures. Lateral grooves of elytra not broader than ridges between 

 them, their strong punctures not drawn out transversely. 



Habits. — -Mr. Kemp tells me that this species lives, in company with flattened 

 Staphylinids and many other kinds of beetles, in deep fissures in very hard jack-fruit 

 logs.
