the ejes, subopaque, distinctly punctured and finely trans- 

 versely rugose in front ; the tubercles rather small and flat, 

 frontal channel moderately broad but not deep, almost as 

 broad between the tubercles as at its termination in line with 

 the back of the eyes ; it is not very distinct when viewed 

 from behind, owing to the fine transversely disposed pubes- 

 cence ; there are two elongate foveas on the vertex. Eyes 

 prominent. Antennce long and stout, pubescent; first joint 

 red, cylindric, punctate, about the length of the following 

 three conjointly ; joints 2, 4, and 5 nearly equal, longer than 

 broad ; third moderately small, longer than broad ; 6 to 8 

 equal, hardly longer than broad, narrowed apically ; ninth and 

 tenth transverse; eleventh short, but with a distinct terminal 

 appendage. Thorax cordate, with a large impression behind 

 the middle; two minute fovege near the base, and a large 

 lateral fossa in front of each posterior angle. Elytra oblong, 

 slightly narrowed towards the base, with well-marked sutural 

 and intrahumeral grooves ; they are not distinctly punctate. 

 Hind body hardly longer than the wing-cases, the two basal 

 segments much depressed at the base, the first with minute 

 brassy scales. Legs robust. Front femora with a deep semi- 

 circular notch near the base ; the middle pair slender at the 

 base, clavate or subangulate underneath. TihicB stout, the 

 front pair slightly arched externally, the outer extremity 

 narrowed or impressed ; the intermediate thick, conspicuously 

 pubescent, much bent inwardly near the extremity ; the 

 posterior slightly bent near the apex. Tarsi moderately 

 slender. 



Underside simple ; head pubescent behind the middle. 



? . Elytra shorter, subquadrate, more narrowed towards 

 the base. Legs robust ; femora not notched ; middle tibiae 

 stout, not bent, only a little narrowed externally near the apex, 

 curved outwardly. Abdomen rather larger, the first visible 

 dorsal segment without minute scales. 



The intermediate tibiee of No. 252 {S. deformipes) are 

 much thicker, the tarsi are nearly twice as thick, and the 

 head and thorax are totally different. The form and sculp- 

 ture of the head, in conjunction with the structure of the 

 legs, will enable S. rugifrons to be recognized without trouble.

Mount Pirongia, March 1894. One of each sex. 



Obs. The discovery of this species, in which there can be 

 no doubt regarding the sexes, is important. It seems to prove 

 that the head of the female in this genus in form and super- 

 ficial appearance does not differ from that of the male ; it also 

 shows that the presence of minute scales on the basal dorsal 

 segment is characteristic of the male.
