OTIORHYNCHIDAE. 413 



some erect, inconspicuous setae, the elytra bear series of quite distinct, 

 subdecumbent grey ones, and outstanding coarser setae form a sutural 

 fringe on the declivity. 



Rostrum slightly contracted near the middle, nearly a third shorter 

 than thorax, finely carinate. Thorax of the same length and breadth, 

 distinctly sinuate and narrowed behind, where, near each side, there is a 

 more or less perceptible carina ; its surface without inequalities, the fine 

 irregularly rugose sculpture hidden by the covering. Scutellum minute or 

 obsolete. Elytra twice the length of thorax, very slightly wider than it is 

 at the base, considerably narrowed but not vertical behind ; they are 

 moderately seriate-punctate, 3rd interstices slightl}' elevated at the base, 

 the 5th, in the female, indistinctly so behind. 



Legs slender. Scape attaining the thoracic margin. Second joint of 

 funiculus almost as long as the basal ; 3rd and 4th distinctly, the following 

 ones slightly, longer than broad ; club elongate-oval, quadriarticulate, the 

 terminal joint small. 



Male.- — Basal ventral segment broadly depressed, 5th as long as 3rd 

 and 4th together, with a shallow depression along the middle. Prosternum 

 deeply incurved. 



Fern.- — Broader, 2| mm. Fifth segment shorter, transversely concave 

 at the base, rounded behind. 



Sharp's Brachyolus longicoUis (2120) is no doubt very similar, but the 

 vestiture must be very different. C. constrictus (3126) is the only other 

 near ally, but the hind-body is jnore asperate. 



^. Length (rostrum inclusive), 6 J mm. ; breadth, 2 mm. 



Moa Basin. Several specimens taken from leaf-mould by Mr. T. Hall 

 during October, 1913. 



3883. Catoptes dehiscens sp. nov. 



Elongate, moderately convex, opaque, piceous, tarsi and antennae fusco- 

 rufous ; covered with round, depressed, irregularly distributed, nigrescent 

 and pale reddish-grey scales, the latter most numerous, smoky-black ones 

 predominate across the summit and along the middle of the posterior 

 declivity ; the setae decumbent and greyish. 



Rostrum a third shorter than thorax, subparallel, distinctly carinate 

 along the middle. Thorax slightly broader than long, oviform, a little 

 wider before the middle than elsewhere, free from inequalities, its puncta- 

 tion invisible. Scutellum distinct. Elytra thrice the length of thorax, 

 slightly incurved, and of about the same width as it is at the base, gradu- 

 ally narrowed posteriorly, with individually rounded, somewhat dehiscent 

 apices ; they are rather finely striate-punctate, interstices simple on the 

 disc, the 2nd and 3rd, and the suture, slightly convex but not at all 

 nodiform near the commencement of the hind slope. 



Scape straight, just reaching the thoracic apex ; basal joint of funiculus 

 a little thicker but scarcely any longer than the elongate 2nd, 3rd and 4th 

 longer than the following ones, 7th obconical, longer than broad ; club 

 elongate. 



Legs rather long, femora medially clavate ; front tibiae longest, arched 

 externally, somewhat bent inwardly below the middle, the others medially 

 dilated, posterior denticulate along the inside, the corbels without any 

 distinct interval between the cilia.
