OF NEW ZEALAND. 1477 



and apex truncate, broadly contracted in front, widest near the 

 middle. Scutellum absent. Elytra slightly sinuate at the base, 

 about the same width as the thorax there, very little broader behind. 

 Legs stout. Femora simple, grooved below near the apex. Tibia 

 mucronate. Tarsi narrow, not elongate, the three basal joints short, 

 the first hardly perceptible above, third entire below, excavate above, 

 the fourth nearly as broad as the third, as long as the basal three ; 

 claws well developed, divergent ; the soles sparingly clothed with 

 long outstanding hairs. 



Prosternum abruptly and deeply emarginate medially in front, 

 between this and the coxae depressed, but with a raised margin in 

 front of the coxae, and prolonged as an acute process between them. 

 Anterior coxa almost touching. Mesosternum with a process between 

 the middle coxae, curved at its apex. Middle coxa globose, distinctly 

 separated. Metasternum short ; hind coxae widely separated. Ab- 

 domen moderate, the basal segment larger than the second, these 

 two without any distinct median suture, third and fourth very short 

 and on a lower plane than the second. 



I know of no near ally. The apex of the rostrum resembles that 

 of ClypeorhynchuSf but the prosternal emargination is like that of 

 Bantiades. 



2556. S. carinatUS, n.s. Subopaque, fuscous, rostrum and 

 legs obscurely rufescent, antennae and tarsi reddish, club paler. 



Hostrum about as long as the thorax, indistinctly bicarinate, 

 with ill-defined sculpture, its apex shining-red. Antenna finely 

 pubescent. Thorax longer than broad, the sides obtusely rounded 

 near the middle, more narrowed in front than behind ; moderately 

 closely and coarsely punctured, each puncture with a minute seta 

 and tawny scale-like matter, it is indistinctly impressed along 

 the middle. Elytra striate-punctate, the punctures rather large, 

 mostly oblong and close to one another ; interstices narrow, the 

 third, and the suture, moderately elevated throughout. Legs with 

 coarse shallow sculpture, sparingly clothed above. Posterior tibia, 

 along their inner face, fringed with pale, elongate hairs ; the others 

 less distinctly. 



Underside opaque, fuscous ; the apical ventral segment red and 

 minutely sculptured ; the basal two with coarse shallow punctures 

 and yellow setae ; the first depressed in the middle ; the second ap- 

 pears as if it were raised behind ; legs with fine yellow setae. 



A second, smaller specimen has no ciliae on the tibiae ; this, no 

 doubt, is the female. 



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



Mount Pirongia. One pair, picked out of leaf -mould brought by 

 Mr. A. T. Urquhart.

Nov. gen. 



Body convex, elongate, gradually but considerably narrowed 

 medially, apterous. Bostrinn moderate, very slightly narrowed
