The following differs from all the species of Agrilus known to me in having a lateral 

 carina to the elytra similar to that in Par agrilus; the basal joint of the posterior tarsi 

 is rather short. I am doubtful whether this species should be included in Agrilus. 



146. Agrilus (?) dissimilis. (Tab. VII. fig. 13.) 



Elongatus, nitidus, viridis ; thorace viridi cyaneo-variegato, crebre evidenter punctato, basi trifoveolata ; 



elytris crebre subasperato-punctatis, ad basin viridibus, dimidio apicali purpureo-cupreo vel seneo, apice 



ipso plerumque viridi, lateribus carina usque ad medium instructis.

The head is moderately closely punctured, with a narrow median channel. The 

 thorax is transversely quadrate, slightly narrowed towards the base, moderately convex, 

 with a fovea inside the posterior ridge and a deeper one in the middle of the base ; 

 the posterior ridge is distinct, curved down to the margin. The elytra have a very 

 slightly marked subcosta ; the lateral ridge extends from the shoulder to about the 

 middle ; the obscure purple or aeneous colour sometimes occupies the apical half and 

 sometimes extends .nearly to the base; the apex is very finely serrate. The prosternal 

 chin-piece is widely but gently emarginate. The presternum is moderately closely 

 punctured ; the intercoxal process is gently convex in the middle, with narrow impressed 

 margins, truncate at the apex. The episterna are smooth and shining, rather strongly 

 and not very closely punctured. 



The smaller specimen differs from the others in having the thorax entirely green, 

 with the posterior ridge longer, and extended more forward, reaching the margin beyond 

 the middle instead of about one third from the base.
