80 SEEEICOENIA. 



The presternum is moderately closely punctured, the intercoxal process sparsely pubes- 

 cent, slightly convex in the middle, not distinctly margined ; the apex very obtusely 

 angular, almost truncate. The abdomen is not very closely punctured, the intercoxal 

 process acutangular.

Parum nitidus ; capite cupreo, antice aurato, creberrime sat rugoso-punctato ; thorace obscure purpureo, trans- 

 versim irregulariter strigoso et ruguloso, medio leviter canaliculate, lateribus maculis duabus aureo- 

 pubescentibus ornatis ; elytris olivaceo-viridis, basi apiceque cuprascentibus, maculis nonnullis aureo-

The head has a very faint impressed line down the front, terminating above the 

 clypeus in a very slight round impression ; the vertex is irregularly striolate and 

 punctured, the intervals between the striolae appearing as rugae. The thorax has the 

 irregular transverse rugae rather finer than the striolee, these latter being finely but 

 not closely punctured ; the central channel is shallow, but well marked — it does not 

 extend to the front margin ; the posterior ridge is distinct and smooth, rather straight 

 (fig. 18 a), and the impression inside of it is filled with golden pubescence, as is also the 

 lateral impression at the anterior angle. The elytra have the following golden-pubes- 

 cent spots : — one in the basal impression, an elongate one in the sutural area extending 

 to the middle, two elongate dashes near the apex (only slightly separated from each 

 other) in the sutural area, and an elongate spot at the side near the apex ; the punctua- 

 tion is rather close but not crowded, and the punctures are somewhat stelliform ; each 

 elytron has a rather strong spine in the middle of the apex (fig. 18 c). The presternum 

 is shining, the punctures fine but distinct, moderately close together ; rugose posteriorly. 

 The metathoracic episterna are closely punctured and clothed with golden pubescence 

 on the outer side, less closely punctured and bare on the inner side. The abdomen is 

 finely and not very closely punctured ; there is a yellow spot on the upper margin of 

 the basal segment, and a spot at the side of each of the apical three segments below ; 

 the lateral carina of the basal segment is nearly rectilinear posteriorly (fig. lSb). 



45. Agrilus spinicaudatus. (Tab. V. figg. 19, 19 a-c.) 



Elongatus, purpureo-niger, sat nitidus ; tborace cyaneo-viridi, striolato et punctulato ; elytris tenuiter rugosis, 

 in sutura vitta aureo-pubescente ornatis, singulo ad apicem spina acuta armato et denticulato (fig. 19c); 

 abdomine pedibusque seneis.

The head is very gently convex in front, and nearly smooth, except for some punc- 

 tures at the base of the antennas; the top is lightly impressed in front, longitudinally
