OF NEW ZEALAND. 19 1 



340. U. tuberculatus, n.s. Body short, very convex, piceous, 

 partially covered with fine, sub-depressed, yellow setae, and erect fuscous 

 setae. 



Antenna with the two basal joints stout, the second short, third 

 longest, eighth a little larger than seventh, club large, they are sparsely 

 pubescent. 



Head granulated, labrum prominent, eyes convex. Prothorax rather 

 transverse, disc transversely convex, sides dilated in the form of two 

 lobes ; the anterior lobe very much larger than the other, narrowed at 

 its base, forming a prominent sub-acute front angle, the posterior 

 obliquely excised behind, with the hind part directed backwards, leaving 

 a short, deep emargination between it and the discoidal portion, for the 

 reception of a small basal lobe of the elytra ; the upper surface is a little 

 uneven and granulated, with the coarse erect setae almost arranged in two 

 rows. The elytra are as wide as the thorax, short, with the base a little 

 emarginated ; the humeral angles are oblique, almost obsolete, but the 

 side, just behind the basal line, is produced in the form of a porrected 

 protuberance, the sides are nearly parallel but crenate, and they are 

 rounded and very declivous behind ; there are two, almost compressed 

 basal tubercles, eight obvious rounded elevations above, and some 

 smaller ones near the sides and apex, and a few punctures are visible 

 near the base. 



The antennae, tarsi, and palpi are red, the tibiae finely setose. 



Length, 2-4- lines ; breadth, ii. 



One example found at Tairua. This and the following species 

 might, I think, be associated together in a distinct genus intermediate 

 between Ulonotus and Syncalus. 



341. U. insignis, n.s. Differs from U. tuberculatus in the form 

 of the sides of the thorax, and base of the elytra. 



The lateral lobes of the prothorax touch each other, leaving between 

 them and the central part a large cavity so that the side has the appear- 

 ance of having been pierced through, the hind lobe is obtusely biden- 

 tate, the protuberances being directed backwards ; the base of the 

 elytra is subtruncate, with two porrected protuberances near each side, 

 the outer is the larger, may be said to form the shoulder, and almost 

 touches the outer portion of the posterior lobe of the thorax, the inner 

 one meets the corresponding tooth of the thoracic lobe, so that between 

 the bases of the thorax and elytra near each side there are two perfora- 

 tions, the external much larger than the inner one. 



The upper-surface generally is similar to that of U. tuberculatus ; it 

 is less dull, more reddened, the elytral elevations are less distinct, and 

 there are several interrupted rows of punctures on the elytra. 



The fine yellow setae are almost entirely confined to the more eleva- 

 ted portions, the erect fuscous setae to the sides, and the tibiae are finely 

 ciliated. 



Length, 2 lines ; breadth, ij. 



Two specimens corresponding with the above description were found 

 near Whangarei Heads. Besides these, I have several others measuring 

 one and a half in length by one in breadth, presenting slight differences
