INSECTS OF SAMOA. 



recently collected in numbers in Tahiti and the Marquesas Group by the members 

 of the " St. George " Expedition. 



62. Agrilus samoensis, sp. n. (Text-fig. 14). 



Elongate, dark bronze coloured, with front of head and sides of thorax 

 aeneous, under side greenish-bronze, elytra with somewhat indistinct macu- 

 lations of pale pubescence. 



Frons moderately flat, with a transverse low ridge, with reduced sculpture, 

 about halfway up. Thorax widest a little behind its front margin, with sides 



feebly sinuate, posterior angles right angles, and with 

 a strong curved carina ; disc finely ridged trans- 

 versely, with fine punctures between the ridges, 

 median line with two impressions. Scutellum trans- 

 versely carinate, the ends of the carina curving 

 rearwards. Elytra rounded and denticulate at the 

 tips, with the usual imbricate sculpture very fine ; a 

 scanty, ashy-grey pubescence on an indistinctly more 

 metallic ground produces the following patterns : a 

 band along the suture behind the scutellum, curving 

 round the latter to the basal impression ; a pair of 

 very indistinct spots obliquely placed, one just behind 

 the basal impression, the other behind and to the 

 outside of it ; a similar pair of spots at about one-third of the length, and a 

 more distinct pair behind the middle ; about halfway between this and the 

 tip, an oblique row of three confluent spots forming a zigzag band, the spot 

 nearest the suture the largest, and just before the tip an indistinct oblique 

 band ; the tip beyond this band more brilliantly bronzy. Posterior tarsi 

 longer than half the tibia, the points of the inner branches of the claws 

 moderately approximate. 

 Long. 8 mm.

(Paratype in Bishop Museum, Honolulu.) 



Closely allied to A. evanidus C. and G., of Java, according to a specimen so 

 determined and marked " compared with type " by Saunders ; but the species
