120 SEKEICORNIA. 



punctured, the punctures separated from each other ; the intercoxal process is slightly- 

 convex, narrowed and rounded at the apex. The episterna are closely punctured, with 

 some pubescence on the outer half. The abdomen is finely and not very closely punc- 

 tured ; the division between the true first and second segments is marked by an 

 impressed pubescent line at the sides ; the lateral carina is very slightly sinuous at this 

 point (with a pubescent spot above), as it is also at the apex of the second and third 

 segments.

The thorax is strongly and evenly punctured, the punctures slightly separated from 

 each other; the median channel is deep, transversely dilated just before the base; 

 the posterior ridge is represented by a considerable swelling, on the inner side of 

 which, close to the base, there is a deep round fovea. The elytra have the subcosta 

 strongly marked, shining, as is also the suture ; the punctuation is rather closer in the 

 sutural area than on the rest of the surface; the punctures are triangular, slightly 

 asperate. The prosternal chin-piece is gently emarginate. The prosternum is strongly 

 punctured, the punctures not crowded ; the intercoxal process is scarcely convex, 

 obtusely angular at the apex. The episterna are clothed with yellowish-grey pubes- 

 cence on the outer half, the inner half being rather finely punctured, the punctures not 

 crowded. The abdomen is finely and not very closely punctured ; the line dividing the 

 true first and second segments is strongly marked at the sides ; the lateral carina is 

 distinctly flexuous at the apex of the first, second, and third segments (fig. 10 a). 



This species much resembles A. brunnipennis, but the discoidal channel of the thorax 

 is more angularly dilated posteriorly, and the fovea within the posterior swelling is deeper. 

 The elytra have the subcosta much more prominent, and the punctuation is closer and 

 rougher. The lateral carina of the basal segment of the abdomen is flexuous ; it is 

 only very slightly so in A. brunnipennis. 



138. Agrilus aurilatera. 



Orassus, parum nitidus, cyanescenti-senens : thorace crebre fortiter punctato, medio sulcato ; elytris sat crebre 



asperato-punctatis, lateribus late cupreis vel auratis ; corpore subtus pube flavo-grisea dense vestito.
