Type in coll. O. E. Janson. 



Only a single male and three female examples of this species 

 are known. It bears the closest resemblance to T. pullus, but can 

 be readily distinguished by a careful comparison. It is broader 

 and much more strongly sculptured and the striation of the 

 pygidium is so dense as to produce a sooty unreflecting surface. 

 The lobe of the pronotum is rather less narrow and without a 

 longitudinal impression at its extremity. A further distinction 

 may be found in the different form of the genitalia of the male.

Bright metallic green above and below, and very smooth and 

 shining. It is large, moderately elongate, depressed above and 



straight-sided. The ch/ijeus is 

 very coarsely punctured, with the 

 margins raised, and the vertex is 

 smooth in the middle. The ^j>'0- 

 notum is rather coriaceous and 

 extremely finely punctured, except 

 in the region of the front angles, 

 where the punctures are very 

 coarse. The sides are contracted 

 in front, where they are consider- 

 ably depressed, obtusely angulated 

 at the middle, and produced out- 

 wards at the hind angles, which 

 are sharp. The basal lobe is 

 minutely rounded at its apex. 

 The eh/tra have a few very minute 

 and inconspicuous punctures, 

 which are a little more apparent at the sides, and the apical and 

 posterior lateral margins are feebly rugose ; the outer edges are 

 scarcely sinuated and the apices are excised near the angles, which 

 are spinose. The j^yciidium is strigose, the metastemum coarsely 

 transversely punctured at the sides, and each ventral segment has 

 a median line of setigerous punctures, except the last, which is 

 entirely punctured. The mesosiernal process is strong, curved and
