HAl'LONYCHIDAE. 569 



converging towards its base. Thorax a third broader than long, distinctly 

 but not abruptly narrowed before the middle, base somewhat rounded ; 

 distinctly but not closely punctured, nearly smooth along the middle, 

 within each puncture there is a minute seta, the squamae are irregularly 

 disposed, almost absent from the middle. Elytra double the length of 

 thorax, of about the same width as it is at the base and closely applied 

 thereto, nearly twice as broad behind the shoulders, posterior declivity 

 considerably narrowed and sub vertical ; they are evidently and moderately 

 closely striate-punctate, quite striate behind, and with convex interstices 

 there. 



Legs long and thick ; femora with depressed, tibiae with more erect 

 greyish setae, the anterior pair broad and very oblique near the outer 

 extremity. 



Second joint of funiculus more slender than the basal but nearly as 

 long, the next slightly longer than broad, joints 4-7 small and subglobular ; 

 basal joint of club scarcely more than half the size of the quadrate second, 

 the terminal narrower. 



Underside nitid, sparingly and finely setose, dark near the middle, 

 rufescent elsewhere. Prosternum incurved in front, flat and not at all 

 canaliculate, the globose coxae nearly as far apart as the intermediate, the 

 posterior more distant. Mesosternum so formed as to appear broadly 

 bilobed. Metasternum very short. Basal ventral segment largest, sub- 

 truncate between the coxae, its punctation transversely subseriate ; second 

 a third shorter, its frontal suture indefinite, longitudinally rugose behind. 



G. setiger (2889), (Ann. Mag. Nat. Hist., ser. 6, vol. 12, p. 295), though 

 somewhat similar in colour, bears curled setae, and the front tibiae are 

 gradually narrowed towards the extremity. G. squamosns (2539) is almost 

 wholly fuscous or piceous, the elytra are not so broad but are more convex 

 along the suture, and the second ventral segment is relatively shorter with 

 a more definite frontal suture. These three species are members of the 

 series, or section, in which the elytra are not flattened towards the sides. 



Length (rostrum inclusive), 2 mm. ; breadth, 1 J mm. 



Huia, near Auckland. Mr. A. E. Brookes, of Mount Albert, found this 

 species on the 10th April, 1915, amongst dead leaves on the ground. 



4115. Geochus apicalis sp. nov. 



Nitid, moderately convex, broadly oval, Avidest near the hind thighs ; 

 thinly clothed with distinct yellowish setae, these are decumbent on the 

 thorax but suberect on the elytra ; variegate, the rostrum, sides of thorax, 

 and basal half of elytra more or less piceous ; the apical portion of these 

 last, the antennae, and tarsi somewhat fulvescent ; thoracic disc dark rufous, 

 legs and club fuscous. 



Rostrum normal, with four flat almost smooth lines converging towards 

 the eyes, which are large and plane with coarse facets, the space between 

 them is half of their own breadth. Thorax about a third broader than 

 long, narrowed anteriorly, moderat(>ly coarsely punctured, more distantly 

 along the middle, usually with a slightly raised, longitudinal, smooth line. 

 Elytra indistinctly wider than thorax at the base, which is oblique towards 

 the shoulders, their sides rounded and a little depressed but not explanate, 

 considerably narrowed and subvertical behind ; they are coarsely substriate- 

 punctate evidently striate behind, interstices convex but not nodiform 

 at the summit of declivitv.
