88 SEEEICORNIA. 



This is a very dark-coloured species, appearing almost black in some lights, or bluish- 

 green. The thorax has the posterior ridge very short and not conspicuous ; it is directed 

 inwards at first, but turns forwards and outwards anteriorly. Each elytron has an elongate 

 basal impression, which is partly filled with dirty yellow pubescence ; there is an elongate 

 pubescent spot just before the middle in a well-marked impression, a lanceolate spot 

 behind the middle, and a narrow line at the apex. The prosternal chin-piece is arcuate. 

 The prosternum is finely punctured and clothed with grey pubescence, transversely 

 impressed below the chin-piece ; the intercoxal process is slightly concave, margined 

 laterally. The metathoracic episterna are closely and finely punctured and pubescent, 

 with a very small smooth spot at the posterior angle. The abdomen is finely and not 

 very closely punctured ; the basal segment has a well-marked impression at a little 

 distance from the sides filled with white pubescence, and the following segments have 

 each a white spot near the margin. The posterior femora are rather incrassate.

The head is closely punctured ; the transverse impression in the middle of the front 



extends nearly from one eye to the other. The thorax has moderately strong, transverse 



(sometimes elongate) punctures, placed close together in the discoidal impression, more 



separated on the raised parts, a small spot on each side of the impression in front almost 



smooth ; the posterior ridge is scarcely raised at the base, but becomes more distinct 



at a short distance from it, curving outwards and downwards anteriorly (fig. 21 a). 



The elytra have the subcosta very obtuse and straight (not sinuous posteriorly as is often 



the case), with some fine scattered punctures ; the punctures on the rest of the surface 



are rather strong, close together in the sutural area,, more separated at the sides, but 



frequently arranged in short transverse lines. The prosternum is shining, and the 



punctures very irregular in shape and position. The abdomen is finely punctured, the 



punctures not very close together ; on the basal segment there is (at some distance from 



the side) a stripe of very pale yellow pubescence, and on the following three segments 



there are spots similarly placed ; the basal segment has at its base an elongate yellow 



spot on the upper surface. The lateral carina is rectilinear posteriorly (fig. 21 b).
