OF NEW ZEALAND. 475 



Thorax rugose on the disc, and punctured laterally. Elytra with six 

 discoidal striae, the two outer interrupted, and three or four others on 

 the side, which are more or less irregular ; their punctation consists of 

 large oblong depressions ; the interstices are slightly convex' and rugu- 

 lose; beyond the middle, on each elytron, there is a large, acute, lateral 

 tubercle, directed upwards and outwards ; the apices are obtusely 

 rounded, singly. Under-side punctate and shining. 



This species is widely distributed ; the descriptions, generic and 

 specific, have been drawn up from specimens in my collection ; the size 

 varies a little ; that now given is the maximum. 



Length, 4 lines (rost. incl.). 



Ancistropterus. 



White; Voy. Er. Terr., Ins. 



Head and thorax much narrower than the elytra at the base ; eyes 

 very large ; beak long, very slightly curved, somewhat thickened at the 

 end ; mandibles prominent, thick and somewhat bent at the end ; antenna 

 very long, springing from a depression on the upper-side of the beak 

 near the end, the scape reaching a little beyond the eyes, nearly as long 

 as the rest of the antennae, second joint as long as third and fourth 

 together, and at the end double their thickness, club long, somewhat 

 pointed at the end, formed apparently of three joints, the two last 

 closely united; elytra together triangular, the shoulders hooked, the 

 hook standing out, each elytron about the middle with a strong, some- 

 what erect spine, bristly at the end ; legs long, femora slightly clavate, 

 with a small tooth below near the end. 



NOTE. In this genus, allied to Scolopterus, the eyes are convex and 

 prominent.
