OF NEW ZEALAND. 1219 



Male. Thorax obsoletely binodose laterally, subopaque, finely 

 and densely punctured ; with a smooth dorsal space, depressed be- 

 hind, and not extending beyond the middle ; and, midway between 

 the medial space and each side, there is a curvate space, raised near 

 the front, also smooth ; it is suddenly contracted near the base, but 

 gradually narrowed anteriorly. Elytra with reddish punctures, but 

 without distinct vein-like marks. 



Female. Thorax distinctly bituberculate at each side, dorsal 

 space nearly smooth, as are also two irregularly- formed curved 

 spaces, one near each side ; the sides closely, the disc coarsely and 

 distantly, punctated. Elytra with, on each, two longitudinal vein- 

 like marks, more distinct than in the other sex. 



In some respects this species resembles Dr. Sharp's 0, dispar. 



$ . Length, 9^ ; breadth, 2J lines. 



Puysegur Point. Mr. Hansen ; one of each sex. 



2252. O. lentiginOSUS, n.s. Pallid, head and thorax tes- 

 taceous, antennae testaceous but with the basal joint rufo-piceous 

 and the second rufescent, legs pallid, elytra of an ivory-like hue, 

 with many fuscous spots. 



Head with a fine median groove, and some rather coarse distant 

 punctures, the punctures are finer behind, they are also small but 

 close near the eyes. Antenna with much slender elongate pu- 

 bescence, the seventh joint reaching the extremity of the body, third 

 and fifth nearly equal. Thorax slightly longer than broad, almost quite 

 oviform, constricted at the base, gradually narrowed anteriorly, 

 densely ciliated in front ; the base, a narrow median space, and an 

 irregular one near each side, almost smooth, but not distinctly raised ; 

 the surface elsewhere finely and closely punctured, and also with 

 many dark, coarse, scattered punctures ; each side bears two smooth, 

 minute elevations. Elytra elongate, glabrous above, densely fringed 

 behind, apices not close together at the suture ; rather closely 

 punctured, the punctures smaller and reddish near the base, fuscous 

 and confluent elsewhere, but leaving two smooth, longitudinal lines 

 on the disc, the suture too is smooth. 



The vein-like marks, and confused maculation of the wing-cases, 

 are distinctive. Didymocantha cegrota, Bates, should be placed in 

 this genus. 



$ . Length, 7 ; breadth, quite \\ lines. 



Wellington. Sandager ; one mutilated individual. 



Pseudosemnus. 



Nov. gen. 



Allied to Leptachrous. Forehead short, vertical, nearly concave,

 stout ; terminal joint of the maxillary elongate securiform and 

 deeply grooved at extremity. Antennce longer than the body in the 

 male ; scape clavate, basal six joints almost nodose at apex and 

 ciliated with outstanding hairs. Pygidium exposed. Mentum 

 20 PT. v.
