OP NEW ZEALAND. 705 



tarsi tri-articulate. Under-side piceous ; the sternum and basal ventral 

 segments punctate and setose. 



Differs from G. incequalis in being more brightly coloured, destitute 

 of superficial irregularities, obviously squamose, and with a plane rostrum, 

 not at all elevated and compressed posteriorly as in that species. 



Length (rost. incl.), nearly i line; breadth, nearly \. 



I detected three or four specimens amongst vegetable matter on the 

 ground, on Mount Manaia, Whangarei Harbour. 



Pachydon. 



Nov. gen. 



Nostrum cylindrical, robust, slightly arcuated, as long as head and 

 thorax ; its anterior half sensibly thickened, so that the front parts of the 

 scrobes are visible from above ; scrobes deep, extending from near the 

 apex to the lower part of the eyes. Antenna stout ; the scape very gradu- 

 ally, but not greatly, incrassated, extending back to the eye : funiculus 

 7-articulate ; first joint stout, slender at base, scarcely as long as the follow- 

 ing two ; second rather longer than third ; third and fourth equal, obconi- 

 cal ; fifth and sixth moniliform ; seventh transverse ; club compact, ovate, 

 pubescent. Head immersed nearly to the hind margin of the eyes. Eyes 

 oviform, placed at the sides of the rostrum, not prominent, coarsely 

 facetted. Thorax cylindric, shorter below than above, slightly rounded 

 in front, truncate at base. Scutellum small. Elytra oblong, widely in- 

 curved at the base, humeral angles oblique, narrowed, and declivous 

 behind, not twice the width or length of the prothorax. Legs robust ; all 

 \hQfemora very perceptibly dentate; tibia a little flexuous, the front pair 

 inwardly produced at the extremity ; tarsi stout, their basal joint not so 

 long as the next two conjointly, slender at the base, second obconical, 

 shortest, third bilobed, broadest, fourth as long as first ; claws broadly 

 dentate. Prosternum plane, unimpressed; mesosternum short; meta- 

 sternum moderate, slightly convex ; basal segment of abdomen largest, 

 rounded and produced so as to broadly separate the posterior coxae ; 

 second as large as the next two, both of which are short with straight 

 sutures, but the first is incurved behind ; fifth sub-conical. Anterior coxes 

 almost contiguous, the intermediate less so. Body squamose. 



1240. P. lineariS, n.s. Body moderately convex transversely, 

 but little shining ; rostrum, head, and thorax reddish ; elytra castaneous- 

 yellow ; legs yellowish ; antennae red, the club darkest. 



Eostrum not longer than head and thorax, considerably stouter than 

 the tibiae, gradually dilated apically, the antennal insertion between its 

 middle part and apex; it is impressed with coarse oblong punctures, 

 many of which have dull white scales in them. Head depressed between 

 the eyes. Prothorax transversely convex, not twice as long as broad, 

 its sides parallel ; its sculpture consists of coarse oblong punctures gene- 

 rally occupied by depressed yellow or whitish scales, those of the latter 

 colour predominating on the middle, the others most conspicuous on the 

 sides. Elytra not abruptly declivous behind, sub-depressed above ; they 

 are strongly punctate-striate ; the squamosity is distributed over the 

 greater part of their length; the pallid scales form two oblique lines ex-
