CRYPTORHYNCHIDAE. 649 



brown above but tawny-grey on the sides of the thorax, on the rostrum 

 they are fusco-fulvous and elongate, and on the elytral suture behind the 

 middle fusco-rufous. 



Eostrum as long as thorax, similar to that of T. complexus in structure 

 and vestiture. Thorax quite a third broader than long, its basal half 

 double the width of the frontal, as closely but more coarsely punctured, 

 the disc a little uneven but without definite crests and not at all carinate 

 along the middle. Scutellum indistinct. Elytra at the base not dis- 

 cernibly broader than thorax, fully twice its length, widest in line with the 

 hind thighs, considerably narrowed and deflexed posteriorly ; they are 

 coarsely seriate-punctate, more finely and substriate behind ; each elytron 

 is unequally tricristate between the base and middle, and bears a curved 

 series of small crests extending along the side and across the top of the 

 posterior declivity, the one on the third interstice is rather larger than the 

 others, and there is a much less distinct series half-way down the declivity, 

 all these are blackish. 



Scape implanted at the middle, attaining the front of the eye, gradually 

 incrassate ; second joint of funiculus slightly longer than the basal, third 

 and fourth oblong, fifth obconical, sixth and seventh transverse ; club 

 ovate, indistinctly 4-jointed. Femora dentiform. 



Underside piceous, with tawny and fuscous squamae, structurally like 

 T. complexus. 



Length (rostrum exclusive), 4 mm. ; breadth, 2\ mm. 



Titahi Bay, near Wellington. Unique. Sent on the 10th August, 1916, 

 bv Mr. A. C. O'Connor. 



4231. Tychanus terricola sp. no v. 



Convex, oblong-oval, opaque ; piceous, antennae and tarsi fusco-rufous ; 

 densely covered with subrotundate, depressed, overlapping squamae, these 

 are chiefly of a rufo-testaceous hue but rather darker on the thorax, which 

 has also many erect, blackish, setiform ones similar to those on parts of 

 the elytra, half-way down the posterior declivity particularly, where they 

 form an irregular transverse streak. 



Rostrum as long as thorax, arched, moderately stout, slightly dilated 

 anteriorly, densely squamose, obtusely ridged along the middle. Head 

 impressed between the eyes. Thorax a fourth broader than long, base 

 bisinuate, the frontal half almost abruptly contracted and fringed with 

 pale .elongate scales at the apex ; disc nearly plane, irregularly and 

 moderately coarsely punctate, with a flavescent streak along the middle 

 of its basal portion. Scutellum indistinct. Elytra on a higher level than 

 the thorax just behind the base, somewhat uneven, of the same width as 

 it is at the base, fully twice its length, rather broader near the hind thighs 

 than elsewhere, strongly curvedly deflexed behind ; apparently subseriate- 

 punctate, third interstices with an obtuse nodiform elevation before the 

 middle, in fine with the fifth there is an obtuse nodosity, or crest, on each 

 elytron, on the summit of the declivity, from this point erect dark scales 

 form an interrupted irregular streak towards each shoulder. Femora 

 distinctly dentate underneath. 



Scape medially inserted, attaining the eye, gradually thickened, setose ; 

 basal joint of funiculus slightly shorter than the elongate second, third and 

 fourth evidently longer than the following three, which are longer than 

 broad ; club elongate-oval. 



Most nearly approaches T. squamosus (3638), from central Canterbury.
