striolate and finely punctured. The thorax is convex, blue-green, shining, slightly 

 and gradually narrowed at the base ; the disc with a feeble impression in front and 

 another at the base ; the lateral impression is well marked, with some white pubes- 

 cence at the anterior angle ; the posterior ridge is fine but distinct, close to the margin, 

 nearly straight when viewed from above (fig. 19 a, lateral view). The prosternal chin- 

 piece is gently arcuate. The prosternum is closely and finely punctured, flat between 

 the coxse and finely margined laterally. The abdomen is very finely and not very 

 closely punctured ; the lateral carina of the basal segment alters its direction posteriorly 

 (fig. 19 5). 



46. Agrilus adjunctus. 



Brunneo-cupreus, parum nitidus ; thoraee transversim ruguloso ; elytris confertim sat fortiter asperatis ; 



antennis femoribusque anticis antice aeneis.

This species has the colour and general appearance of the European A. sinuatus, but 

 is narrower, more attenuated posteriorly, and the elytra have the subcosta well marked, 

 and have a distinct spine at the apex. The head is somewhat dull, very closely and 

 distinctly punctured ; the face is longitudinally impressed in the middle, and has a very 

 slight oblong swelling on each side. The thorax is closely rugulose, and has some 

 coarse punctures at the anterior margin ; there is an inconspicuous, narrow, lanceolate 

 impression at the base ; the lateral impression is shallow and not well marked ; there 

 is some whitish pubescence at the anterior angles ; the posterior ridge is fine, smooth, 

 and curved down to meet the margin near the middle — it is somewhat interrupted at 

 the base by the uneven surface. The elytra have the subcosta obtuse but well marked 

 and reaching to the apex. The prosternum is densely rugose. The episterna are 

 clothed with fine pale grey pubescence, and the pubescence extends also on to the sides 

 of the metastemum and base of the metathoracic episterna; the latter are closely 

 punctured and slightly rough posteriorly. The abdomen is finely and not very closely 

 punctured ; there is a small spot of pale pubescence in an impression about the middle 

 (somewhat removed from the side) ; and an elongate spot at the side of the second and 

 third segments. 



47. Agrilus gracilipes. 



Obscure aureo-Eeneus, sat nitidus ; thoraee transversim strigoso, ad angulos posticos linea elevata recta nitida 



instructo ; elytris rugulosis, apice parum ampliato, denticulato, cupreo-tincto ; pedibus gracilibus.
