184 COLEOPTERA 



differs in the structure of the antennae, and from the former in the 

 deeply indented sides of the prothorax. 



Its chief characters are as follow : — 



Labrum exposed truncate. Epistome truncate. Ajitennce, eleven- 

 jointed, their club obviously two-jointed ; the two basal joints are stout 

 and sub-cylindrical, the first but little exposed ; third elongate, slender, 

 twice as long as the fourth ; fourth to ninth small, sub-obconical, the 

 ninth one-third of the width of the tenth ; the tenth and the eleventh 

 form a rather compact, well-defined club, the former transverse, the 

 latter large and obtusely rounded. 



Body oblong, moderately convex transversely, with the prothorax 

 deeply indented laterally. 



326. A. ornatus, n.s. Ohlong, rather convex transversely, uneven; 

 it is fuscous, but with the base and sutural region of the elytra reddish, 

 the legs and antennae are reddish, the club infuscate ; the body is 

 clothed with fine yellow setae, which are sparingly distributed on the 

 head, on the thorax they are almost confined to the elevated portions ; 

 on the elytra they form six lines, the sutural and one nearest to it reach 

 the apex, the next two are abbreviated, the fifth extends along the edge 

 of the disc, the last along the margin, between these two latter there is a 

 row of small patches which are very distinct, owing to the blackish 

 colour of the side, and the raised portions are covered with similar pale- 

 yellow setae ; on each side of the elytra, behind the middle, there is a 

 large triangular space without distinct elevations and nearly black. 



Head granulated. TJwrax transversely convex, with explanated, 

 indented sides, the indentations form four lobes, the anterior largest, its 

 apex forming a prominent acute angle, the second and third are equal 

 and equidistant, the fourth is smallest and leaves an evident gap between 

 it and the base of the elytra, the sides are clothed with pallid, scale- 

 like matter ; its surface is uneven, with a large dorsal and small basal 

 depressions defined by curved, angular elevations, it is apparently 

 granulated. The elytra are oblong, of the same width as the thorax, 

 with parallel, compressed sides, rounded and abruptly deflexed behind \ 

 each is curved at the base, bears two basal, sub-compressed tubercles 

 most distinctly seen when viewed from the side, the outer near the 

 shoulder, the other near the suture, with a smaller elevation interposed ; 

 two smaller ones form an oblique line from the suture to the shoulder ; 

 and, close to the posterior declivity, there are two other contiguous 

 ones ; besides these there are other tufts of setae which form "apparent" 

 elevations, but which it is needless to describe in detail. The tibm are 

 finely ciliated.

Two examples found at Whangarei Heads, one rather smaller than 

 the other whose size is given. The description of the coloration is only 

 applicable to the two recently captured individuals; on examining three 

 others which had been found at Tairua, I find the yellow colour of the 

 setae has degenerated into a grey, the black also has faded, so that the 

 appearance of the insect is greatly altered. The indentations at the
