558 COLEOPTERA 



convex and cylindrical than in E. lawsoni, but in other respects the two 

 insects seem quite similar. 



Auckland (Mr. Lawson). 



NOTE. The species also occurs at Tairua. 



980. E. spectabilis, n.s. This fine species may be at once 

 recognized by its larger, more elliptical form. It is of a pale reddish- 

 brown colour above, the antennae and legs are paler than the body and 

 somewhat testaceous, but without the slightest tinge of green; the elytra 

 are variegated with piceous spots on the interstices ; the clothing con- 

 sists of griseous hairs, which are most conspicuous on the head, least so 

 on the elytra, where it is intermingled with patches of whitish pubes- 

 cence on the interstices. The antenna, of the male are four times the 

 length of the body (not including that portion of the rostrum anterior 

 to the deep, foveiform scrobes) ; the basal joint is very stout and rounded, 

 not obliquely truncated at the base ; the seconjd joint is nearly as long 

 as, but much more slender than, the first, of an obconical form ; joints 

 three to eight become longer and more slender, and are sub-clavate at 

 the apex ; the ninth is of about the same length as the fourth, and 

 gradually widened till it becomes as broad as the two apical joints, the 

 last being longer than the penultimate. The rostrum is moderately 

 elongate, very slightly dilated laterally above the scrobes, and indis- 

 tinctly grooved and carinated. The eyes are reniform, and differ from 

 those of the typical species in having the upper portion narrower than 

 the lower. The thorax is somewhat oviform and convex ; the carina is 

 almost truncate in front of the scutellum, from thence oblique, and at 

 the sides directed forwards obliquely to the middle of the prothorax ; 

 its surface is obsoletely sculptured. Scutellum small. The elytra are 

 oblong, a little wider than the thorax ; each elytron bears nine indistinct 

 striae in addition to the marginal channel, and scutellar stria, all of 

 which are distinctly punctured ; the sutural as well as the third, fifth, 

 and seventh interstices are slightly elevated. Tibia slightly flexuose. 



Length, 2\ lines. 



The female is smaller, scarcely 2 lines long, with antennas not much 

 longer than the body. 



I found several specimens on the Nikau, at localities near Whan- 

 garei Harbour. 



Arseocerus. 



Antenna as long as head and thorax, inserted in deep, oblique 

 cavities, at the sides of the rostrum, just in front of the eyes ; the basal 

 joint is curved, very slender at the base, but strongly dilated at the apex ; 

 the second is smaller than the first, with a slender base, and consider- 

 ably enlarged near the middle ; the third and fourth are slender, sub- 

 ovate, of nearly equal size, and nearly as long as the fifth ; sixth and 

 seventh short ; eighth subtriangular ; ninth distinctly larger than the 

 preceding joints, sub-triangular ; tenth transverse, cup-shaped ; eleventh 

 rounded. Rostrum short, quadrate. Eyes rather large, very prominent,
