behind this patch ; mesothoracic episterna crossed by oblique band of punctures or 

 with their upper angles punctured throughout; mesosternum finely striatopunctate at

 grooved or keeled in the middle behind; metasternum as in the preceding species- 

 except that an obscure median longitudinal keel is present and the lateral areas are 

 even smoother. Abdominal sterna and hind coxae polished, unpunctured. Tibiae of 

 middle legs with one blunt tooth slightly below the middle; those of hind legs

Mr. Stevens' collection includes a specimen from Silonibari at the base of the 

 North Lakhimpur Hills in Assam. 



Description. — Length 20-22 mm. Labrum as in T. bicanthatus. Mandibles as in T. 

 pygmaeus but with anterior lower tooth slightly more compressed. Mentum not unlike 

 that of T. pygmaeus, but with median prominence of anterior margin almost absent 

 or entirely so, the central area being consequently quadrangular; distinctness of central 

 area from adjoining parts somewhat variable as (in specimens from the Darjeeling 

 District especially) it is apt to be punctured, and in extreme cases (e.g. ^^ and ^') 

 the whole surface of the mentum appears uniformly punctured and hairy. Head 

 smooth, with a transverse patch of strong punctures at the back on each side behind 

 supra-orbital ridges. Anterior margin bordered by a strong groove, slightly convex in 

 the middle and slightly concave on each side; meeting crest of supra-orbital ridge
