OF NEW ZEALAND. 1051 



This species, though somewhat akin to S. elevata, differs from it 

 as follows : 



The head is broader behind, but not angularly dilated laterally 

 as in S. genalis and S. insignis. The elytra are shorter, and more 

 narrowed towards the base. The hind-body is a good deal more 

 elongate. The tibia are less arched, nearly straight in fact. "Tire 

 tarsi are evidently shorter. The whole contour of the body is 

 different, being narrower and more elongate. 



Length, 1-J lines; breadth, nearly f line. 



Mokohinou Island. Mr. Sandager. 



1878. S. rectipes, n.s. Shining, yellowish, rather pale, the 

 antennae, head, and thorax slightly rufescent ; clothed with pallid 

 hairs ; subdepressed, elongate and narrow. 



Head moderately rounded behind the eyes, having two distinct 

 rounded foveae on the occiput, the frontal furrow prolonged as far 

 back as the middle of the eyes, not very broad ; the tubercles much 

 flattened. Eyes not prominent. Antenna half the length of the 

 body. Thorax cordiform, convex in front, widest near the middle, 

 its impressions small. Elytra quite oblong, slightly narrowed an- 

 teriorly, intrahumeral impressions elongate. Hind-body not greatly 

 exceeding the elytra in size, no wider. Legs long and slender, 

 tibiae not externally curvate, only gradually widened towards the 

 extremity. 



The narrow, elongate form and straight tibiae are distinctive. 



Length, 1 ; breadth, line. 



Tairua. 



1879. S. insolens, n.s. Body robust ; head and thorax red, 

 abdomen castaneo-rufous, elytra and legs rufo-testaceous, basal 

 joint of antennae red, the others become paler ; pubescent. 



Head somewhat rounded behind, almost as broad as the thorax ; 

 the antennal tubercles behind on the same plane as the head itself ; 

 their channel not continued further back than the front part of the 

 eyes, and not expanded or foveiform, occipital foveas small ; it bears 

 some pale hairs, and seems as if punctate. Eyes convex. Antenna 

 stout. Thorax cordate, widest before the middle, with the usual 

 fossa behind the middle, a small one near the hind angle, the lateral 

 depression large. Elytra broader than thorax, broader still behind, 

 not twice as long as broad, the intrahumeral impressions consisting 

 of a basal puncture and elongate groove. Legs stout, tibiae slightly 

 arched outwardly, armed with a distinct spur at the inner apex ; 

 anterior femora with a deep wide notch underneath near the 

 base. 



S. convexa is the nearest form, it has the same excision of the 

 front thighs, but S. insolens has hardly any trace of a frontal fovea, 

 and joints 4-6 of the antennae are decidedly larger. 



Length, 1J lines ; breadth, f line. 



Found near Ho wick ; two individuals only.
