416 COLEOPTERA. 
Length (rostrum inclusive), 3} mm.; breadth, 1} mm. 
Mount Algidus, Canterbury; 25th September, 1913. Another unique 
from Mr. T. Hall. 
3887. Catoptes flaviventris sp. nov. 
Opaque, without inequalities ; fuscous, rostral apex rufescent, legs and 
antennae fusco-testaceous ; densely clothed with depressed fuscous squamae, 
but just below the summit of the posterior declivity there is a broad band 
of paler brown scales; the small serial setae on the elytra are white and 
decumbent but suberect behind. 
Rostrum subparallel, only feebly dilated in front, a third shorter than 
thorax, not in the least depressed at the base, obsoletely carmate. Thorax 
oviform, slightly broader than long, its sculpture invisible, with some minute 
whitish setae on the disc. Scutellum small. Elytra quite twice the length 
of and a third broader than the thorax, incurved and distinctly broader 
than it is at the base, narrowed but not vertical behind ; apparently striate- 
punctate, with simple interstices, the suture somewhat convex behind. 
Underside fusco-testaceous, with pale scales and slender elongate setae. 
Prosternum deeply emarginate, with contiguous coxae. Basal segment as 
long as the metasternum, both broadly impressed along the middle, 2nd 
rather shorter, its frontal suture sinuate, 5th as long as 3rd and 4th 
combined, rounded behind. 
This resembles C. pallidipes in structural details with the exception of 
the ocular lobes, which are obsolete. The eyes, antennae, and legs are 
similar. The hind-body is more oblong and narrower, and there is no basal 
depression of the rostrum. The only example extant has strongly developed 
supplementary mandibles, the left being curved and acute at the extremity. 
$. Length (rostrum inclusive), 34mm.; breadth, nearly 14 mm. 
Mount Algidus. A single individual found by Mr. T. Hall on the 25th 
September, 1913. : 
3888. Catoptes nigricans sp. nov. 
Opaque, nigrescent, antennae fusco-rufous, legs pitchy-red; covered 
with ashy scales nearly as dark as the derm, and with decumbent greyish 
setae, these give the rostrum a speckled appearance. 
Nearly allied to C. flaviveniris. The rostrum feebly carinate along the 
middle. Thorax as long as broad. Scutellum small, indistinct. Elytra 
hardly double the length of thorax, slightly broader than it is at the base, 
distinctly substriate-punctate, interstices simple. Eyes rather smaller and 
more distant from the thorax. 
Underside black, nitid, with white scales and elongate setae. Proster- 
num moderately incurved. Basal segment rather longer than metasternum, 
depressed along the middle, 2nd flat, both distinctly punctate. 
3. Length (rostrum inclusive), 3}mm.; breadth, 14mm. 
Searcliff ; 19th October, 1913. Two from Mr. Hall, one damaged. 
3889. Brachyolus bicostatus sp. nov.  Brachyolus White, Man. N.Z. 
Coleopt., p. 1194. 
Elongate, convex, opaque, piceous, antennae and tarsi fusco-rufous ; 
covered with depressed, infuscate-tawny scales, and coarse, decumbent, 
greyish setae, those on the legs erect.
