The head is strongly and closely punctured, except on the inner side of the round 

 swelling on each side of the lower part of the face ; there is a very slight prominence 

 above each eye. The thorax has its anterior margin somewhat raised in the middle, 

 and projecting very slightly over the head ; the impressions are marked with numerous 

 short, curved, or wavy deeply impressed lines ; the sides are rugulose ; on each side of 

 the central impression there is a small smooth spot on the elevated part. The elytra 

 are transversely impressed at the base (leaving the shoulders somewhat elevated), and 

 gradually curved down to the apex ; the costa on each is very obtuse, interrupted at 

 intervals by the small impressions; there are strong punctures on and just below the 

 shoulder, and at the apex ; and at the side behind the middle there are numerous 

 asperities. The prosternal process is very strongly and closely punctured. The middle 

 of the short metasternum and the intercoxal process of the abdomen are sparsely and 

 delicately punctured. The sides of the abdomen are clothed with fine pubescence of a 

 slightly golden colour, which forms a large spot on the second segment and a small 

 one on the first and third segments. 



2. Agrilus diversus. (Tab. IV. figg. 11, 11 a.) 



Nigro-purpureus ; capite cupreo, erebre punctato, fronte supra incisa, binodosa ; thorace crebre punctato et 

 flexuoso-strigoso, disco sat profunde impresso, lateribus rugulosis, antice oblique impressis, ad angulos 

 posticos carina brevi lsevi ; elytris confertim subtiliter rugulosis, dorsim planatis, postice inclinatis, pallide 

 griseo-maculatis, apice denticulate, lateribus obscure seneo-viridibus ; prosterno creberrime punctato.

The ovate punctured swellings on the face of this species are on the upper part 

 raised above the level of the eyes. The thorax has its discoidal impression not so deep 

 as in the preceding species, narrow in the middle, widest behind ; the raised parts on 

 the disc are generally tinted with green. The pale grey pubescence which forms the 

 markings on the elytra is extremely short. Each elytron has a small acute tooth at the 

 apex near the suture. The punctuation on the prosternum is very dense, less so on 

 the metasternum (though confluent transversely). The abdomen in the middle is less 

 closely and much less strongly punctured ; the apical segments sparsely clothed with 

 pale pubescence. The middle of the metasternum and abdomen are seneous. One 

 example has the sides of the metasternum slightly coppery. 



3. Agrilus oculatus. 



Fusco-cupreus, parum nitidus ; capite fortiter excavato ; thorace fortiter punctato et vermiculoso, insequali; 



elytris rugosis (maculis irregularibus laevibus notatis), fusco et seneo variegatis, litteris guttisque griseo- 



pubescentibus ornatis.
