 crebre punctato et transversim ruguloso, disco bi-impresso, angulis posticis linea nitida curvata instructs ;

The head is longitudinally impressed on the forehead, which is bigibbose ; the 

 punctures on the front are moderately close together and not very distinct, those on 

 the vertex being much stronger and longitudinally confluent. The thorax has two 

 shallow impressions on the disc, one at the base, and one in front of the middle ; th e 

 posterior ridge is curved and punctured, and consequently not very conspicuous. The 

 elytra have the punctures rather strong and united transversely by double parallel 

 lines ; the pale whitish-grey spots are placed in the sutural impression — one in the 

 basal impression, one before the middle, one behind the middle, and one smaller one 

 near the apex ; at the apex they are parallel ; each is emarginate, denticulate at the 

 outer angle and sutural angle, with a strong acute spine at the outer side of the emar- 

 gination (fig. 6 a). The prosternum is very closely and moderately strongly punctured, 

 slightly shining, sparsely pubescent. The metathoracic episterna are moderately 

 closely and strongly punctured and sparsely pubescent. The abdomen is shining, very 

 finely and moderately closely punctured ; at the sides are two obscure sparsely pubes- 

 cent pale greyish spots ; the lateral carina of the basal segment alters its direction 

 posteriorly (fig. 6), 



25. Agrilus cribricollis. (Tab. V. figg. 8, 8 a-c.) 



Omnino brunneo-seneus, parum nitidus ; thoracis disco fortiter sat crebre punctato, transversim ruguloso, 

 medio in longitudinem profunde impresso ; elytris tenuiter flavo-griseo-pubescentibus, regione suturali 

 creberrime subtiliter punctulato, maculis nonnullis fere calvis nitidis ornatis, lateribus confertim 

 rugosis, apice ipso rufo-cupreo, denticulato.

The head is coarsely punctured on the vertex, triangularly impressed in front, the 

 face very finely punctured and pubescent, with two small smooth raised spots in the 

 middle ; the clypeus and a line running along the inner side of the eye shining 

 coppery. The thorax is coarsely punctured on the disc, with the intervals confluent 

 transversely in front; the deep longitudinal impression is indistinctly punctured, 

 narrowed in front ; the sides are finely rugose ; the posterior ridge is well defined, 

 shining, rather swollen and raised anteriorly (fig. 8 a). The elytra are sparingly 

 clothed with short greyish-yellow pubescence, except at the apex (fig. 8 c). Each 

 elytron has four bare, more shining spots — the first, near the base, does not touch the 

 subcosta nor the suture ; the second and third touch the subcosta but not the suture ;
