tatis, versus angulos externos posteriores fere Isevigatis. 

 Long. Corp. 5^ lin. 



Antcniife slender, with joints 1 and 2 yellow, 3 — 7 

 black (the rest wanting); basal joint rather short, scarcely 

 longer than the 3rd joint, this being hardly one and a half 

 times the length of the 2nd joint. Palpi yellow ; man- 

 dibles pitchy, reddish at the extremity. Head small, 

 shining, bluish-green, densely and very coarsely punctured, 

 bearing a few fine pale hairs; transverse space between the 

 eyes smooth and shining. Thorax about | lin in length, 

 and about the same in breadth, slightly rounded at the 

 sides, and slightly narrowed behind ; the disc flattened and 

 coarsely and densely punctured, the margins with only a 

 few scattered punctures, this free space being largest on 

 the front near the angles; the colour is shining bluish- 

 green, like that of the head. Elytra about as long as the 

 thorax, rather broader than long, shining blue, rather 

 finely and sparingly punctured; the punctures rather 

 coarser and closer at the suture behind the scutellum than 

 elsewhere, becoming finer towards the extremity and sides, 

 so as to be wanting at the hind angles. Hind body black 

 and shining, sparingly punctured, the hind parts of the 

 segments impunctate, the 6th and 7th only very finely 

 punctured, the outstanding black setiB well marked. Legs 

 short and stout, black, with the front tarsi pitchy above, 

 pale beneath; under face of hind body more coarsely 

 punctured than the upper. 



Ega; a single female. 



This sjjecies, though it greatly resembles, at first sight, 

 T. tarsalis and the allied species, may be readily distin- 

 guished by the dense and regular sculpture of the thorax, 

 the punctures being all large and crowded together on the 

 middle, instead of being of unequal sizes and unevenly 

 distributed.
