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 slightly 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. 
Fem.—Broader, 24mm. Fifth segment shorter, transversely concave 
at the base, rounded behind. 
Sharp’s Brachyolus longicollis (2120) is no doubt very similar, but the 
vestiture must be very different. ©. constrictus (3126) is the only other 
near ally, but the hind-body is more asperate. 
$. Length (rostrum inclusive), 64 mm.; breadth, 2 mm.

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.
