94 SEEEICOENIA. 



punctured, the intervals appearing like rugae in some lights ; the median channel is 

 tolerably well marked, but it does not reach the front margin ; the posterior ridge is close 

 to the margin, scarcely visible from above — when seen sideways, it is distinct, curved 

 down to the margin about the middle (fig. 23 a). The elytra have the subcosta fairly 

 well marked ; the sutural stripe is not conspicuous, but it extends from the base to the 

 apex ; the apex is denticulate, one tooth being a little longer than the others. The 

 whole of the sternum is sparsely clothed with pale grey pubescence. The prosternal 

 chin-piece is short, nearly straight. The prosternum is closely and finely punctured ; 

 the intercoxal process is nearly flat, with smooth lateral margins, very obtusely angular 

 at the apex. The episterna are finely punctured and pubescent. The abdomen is 

 finely and not very closely punctured; the intercoxal process obtusely angular; the 

 basal segment convex, with a stripe of pubescence at some distance from the side ; the 

 second and third segments with a slight spot at the side ; the lateral carina is slightly 

 angulated behind the middle (fig. 23 b). The basal joint of the posterior tarsi is not 

 very long.

Niger, nitidus ; capite convexo, ruguloso, antice fovea parva impresso ; tborace convexo, ruguloso, medio 

 sulcato, angulis posticis carina obliqua valida instructis ; elytris rugosis, sub humeris compressis, maculis 

 seneis griseo-pubescentibus ornatis, apice denticulate.

The head has a small impression just above the clypeus. The thorax is rather long, 

 advanced in the middle of the front margin, very gently arcuate at the sides, almost 

 straight behind ; convex, impressed at the base ; rugulose, the rugae close and various 

 in their directions ; the median channel is deep and narrow ; the posterior ridge is 

 shining and sharply defined, straight, directed obliquely inwards to a little beyond the 

 middle of the length of the thorax (fig. 24 a). The elytra have no defined subcosta, 

 but are rather impressed about the middle ; each elytron has a quadrate aeneous spot 

 near the suture at one quarter from the base, an oblong one about the middle, and an 

 oblique, rather broad fascia at a short distance from the apex, all clothed with silvery 

 pubescence ; the apex is obliquely truncate inside and outside, and finely but 

 distinctly denticulate. The prosternal chin-piece is almost imperceptibly emarginate. 

 The prosternum is coriaceous, with numerous transverse punctures ; the intercoxal 

 process is gradually acuminate posteriorly. The episterna are slightly pubescent on 

 the outer margin ; shining on the inner part, with rather large vague punctures. 

 There is some pure white pubescence at the sides of the metasternum, a spot above 

 the margin of the basal segment of the abdomen, and a spot at the side of the second 

 segment. The lateral carina of the basal segment is distinctly curved about the 

 middle (fig. 24 b).
