FAHONINI. 291 



The prominent, obtusely bifid apex of the last dorsal segment is its 

 principal differentiating feature. The ventral segments, in structure, 

 most nearly resemble those of S. fulvipennis. The elytra in shape are like 

 those of *S'. sulcator, 1575, which belongs, as does the present species, to 

 Section IX, but 1575 has a broader and more rotundate head, its frontal 

 channel is prolonged right to the base, and the occipital foveae are minute 

 and apt to be overlooked.

Woodhill, Kaipara Railway. One found on the underside of a log bv 

 myself many years ago. 



3707. Sagola posticalis sp. nov. 



Elongate, subparallel, subdepressed, nitid, finely and irregularlv punc- 

 tate ; fusco-rufous, antennae and legs paler, palpi and tarsi yellow ; thinlv 

 clothed with suberect greyish pubescence. 



Head almost as broad as thorax, contracted in front, very slightly 

 curvedly narrowed behind, with obtuse angles, eyes moderately prominent ; 

 antennal tubercles nearly plane, finely yet distinctly punctured, frontal 

 channel deep, moderately broad, narrowed anteriorly, extending as far as 

 the back of the eyes, occipital foveae small and punctiform. Thorax of 

 about equal length and breadth, rounded and widest just before the middle, 

 apex much narrowei- than the occiput ; basal fovea subrotundate, the lateral 

 ones deep, hardly reaching the middle, base finely bipunctate. Elytra 

 flat, suboblong, slightly narrowed before the middle, a third longer than 

 thorax ; sutural striae deep, with a basal puncture alongside each, intra- 

 humeral striae deep, prolonged to the middle, usually tripunctate. Hind- 

 body as long and broad as elytra, basal segment much shorter than 2ud 

 or 3rd, apical segment short and broad, subangulate at extremity. 



Legs moderately elongate, tibiae slightly expanded below the middle. 



Antennae longer than head and thorax, moderately slender, very slightly 

 and gradually thickened ; basal joint red, not double the length of the 

 oviform 2nd : 3rd small, very little longer than broad : 4th oviform, 

 evidently smaller than 2nd ; joints 5-7 narrowed apically ; 8-10 laxly 

 articulated, transverse, only slightly broader than preceding ones, the 

 terminal conical, not twice the length of penultimate. 



Ventral segments 2-5 normal, 6th as long as 5th, unusually broad, 

 semicircularly emarginate, enclosing the very small subrotundate 7th. 



Fem.- -6ti\ segment short, broadly triangular. 



Like S. sutiiraUs, 3522, Section X, in some respects, but smaller and of 

 a lighter hue. The head manifestly broader. Elytra rather more narrowed 

 near the base, and therefore less perfectly oblong : intrahumeral striae 

 nruch longer and tripunctate, but with a single puncture only between them 

 and the suture. The rather broad, medially angulate, apical dorsal seg- 

 ment will lead to its separation from other species.

3708. Sagola laetula sp. nov. 



<Jlossy, subdepressed, not perceptibly punctate, elytra and hind-body 

 parallel ; castaneo-rufous, elytra fulvescent, legs slightly more infuscate 

 than elytra, palpi and tarsi yellow ; very thinly covered with fine vellowish- 

 grey pubescence and upright elongate setae.
