OF NEW ZEALAND. 1227 



In form and sculpture like the preceding (E. nobilis) but with 

 more slender legs. The erect hairs on the hind-body are conspicu- 

 ous, and there are some blackish ones on the thorax. The second 

 joint of the funiculus is about as long as the first, but slender, the 

 third is rather longer than the fourth, both of these are obconical, 

 joints 4-7 are moniliform, the club is ovate-oblong. 



Length (rost. incl.), 3^ lines; breadth, 1 line. 



One example. Mount Arthur. Cheeseman and Adams. 



2161. E. cyaneus, n.s. Body blue, elytra tinged with green, 

 antennae blackish, tarsi and club more or less infuscate ; clothed 

 with slender ash-coloured hairs, and bearing also some erect but not 

 coarse ones on the wing-cases. 



In form, colour, and clothing, just intermediate between E. 

 c&nescens and E. tar satis. The antennae and tarsi resemble those of 

 the former species, the funiculus, however, is rather shorter, the two 

 basal joints are not so stout, and the third is not appreciably longer 

 than the fourth, which is obconical, joints 5-7 are bead-like ; the 

 club is ovate-oblong and distinctly articulated. The pygidium is 

 horizontally protuberant, subtriangular, and coarsely sculptured. 

 The superficial sculpture and other details do not differ materially 

 from those of E. cenescens. 



Length (rost. incl.), 3-| lines; breadth, 1 line. 



From the same locality as the foregoing species. 



2162. E. tarsalis, n.s. Elongate, dark-blue, antennae pitchy- 

 black, tarsi infuscate ; very sparingly clothed with minute greyish 

 hairs, none of which are at all conspicuous. 



Eesembles E. tenescens in sculpture and in structure, but the 

 form is somewhat different. The thorax is a little shorter; the 

 elytra are not subtruncate at the base as in that species but are dis- 

 tinctly bisinuate, they are rather shorter and very gradually narrowed 

 from the shoulders backwards, and, moreover, the apices are 

 obviously individually rounded. The pygidium is of oblong form, 

 prominent, and apparently quite smooth and shining ; most likely, 

 however, this is merely a sexual character. The tarsi are remark- 

 ably slender and elongate ; the two basal joints, singly, equal the 

 terminal in length, even the third is but little expanded, the apical 

 is similar to that of the other allied species. The antenna are more 

 elongate, the second joint of the funiculus quite equals the first, 

 the third is decidedly longer than the fourth, the others decrease 

 gradually ; club elongate, ovate-oblong. 



A second example is faintly aeneous, the club is a little rufescent, 

 and the after-body is a little larger. 



Length (rost. incl.), 2| lines; breadth, J- line. 



Derived from the same source as the other cognate forms. 



2163. E. lituratus, n.s. Black, scape rufescent, tibiae and 

 tarsi obscure rufo-fuscous ; the clothing of the elytra to beyond the 

 middle consists of fine upright greyish scattered hairs, and more
