1 90 COLEOPTERA 



ceous, in the other dark brown, the sides and front of the thorax, and 

 spots on the elytra, particularly near the shoulders, paler ; palpi, tarsi, 

 and antennae red, with the club infuscate, legs reddish, with some 

 brown. Head transversely impressed in front, finely granulated, with a 

 few, fine, depressed, yellow setae. Thorax about as long as broad, with 

 moderately explanated sides, slightly, but widely, incurved at the 

 middle and serrate, front angles prominent, posterior nearly rectangular; 

 its surface finely granulated, and bearing on each side of the middle 

 two more or less obvious tubercular elevations, giving the dorsal space 

 a depressed aspect, there are two others near the base, so that there 

 appears to be a fovea in front of the scutellum, it is clothed like the 

 head, but the setae are most evident on the elevated spots. The elytra 

 are elongate, transversely convex, parallel ; they seem, at first sight, to 

 be striate, but, when carefully examined, it is seen that this appearance 

 is caused by rows of shining, interrupted, granular elevations, and there 

 are six nodules on the third, fifth, and seventh interstices, these however 

 do not accurately correspond. Third antennal joint twice as long as 

 fourth. 



Length, 2-2^ lines ; breadth, f . 



I found three specimens, two at Tairua, one at Whangarei Heads. 

 I sent one to Dr. Sharp who informed me it was not U. lawsoni; I 

 think, however, it must be a nearly allied, but aberrant form. 



339. U. atratUS, n.s. Oblong, black, the sides of the thorax, a 

 spot near the middle of each elytron at the side, and four smaller ones 

 (two on each) along the base, white ; antennae and tarsi dark-red. The 

 basal and second joints of the antenna are stout and cylindric, only the 

 apex of the former visible from above ; third rather longer, but more 

 slender than second ; joints five to eight about equal ; club distinct. 

 Head granulated. The thorax rather longer than broad, disc transverse- 

 ly convex, outwardly curved anteriorly ; the sides are explanated, with 

 a large frontal lobe which has an indentation near the middle, a small 

 one behind the middle, and a third, also small, which forms the pos- 

 terior angle ; the base in its central portion is closely applied to the 

 elytra, but recedes from them towards the hind lobes ; the surface is 

 uneven, there being a large dorsal depression, and a much smaller one 

 near the scutellum, three tubercles near each side of the central line, 

 the rest of the surface bears many small granules. 



The elytra are oblong, a little wider than the thorax, the sides 

 parallel to beyond the middle, from thence rounded, with the apices 

 somewhat divergent ; the rounded posterior part is tubercular, the rest 

 of the margins, though without distinct indentations, are rather uneven ; 

 there is an irregularly formed tubercle on each side of the suture near 

 the base, and several large rounded elevations are distributed over 

 their surface. 



The whole surface of the body is more or less granulated, and the 

 tibiae are ciliated with fine setae. 



Length, 2 lines ; breadth, f . 



I found one example only at Tairua.
