372 JOURNAL OF SCIENCE, 
other parts of the elytra fuscous, head slightly rufescent ; clothed 
with pale brassy hairs. 
Head moderate, finely granulated. Pvyothovax nearly as broad 
as base of elytra, minutely and rather distantly granulated. 
Elytra widest behind, moderately closely and rugosely punc- 
tulated, very slightly depressed just behind the scutellum. 
A rather short ovate species, with a moderately developed 
subocular carina; allied to C. osculans, but readily enough 
identified by the minute and distant granules on the thorax. 
Length, 1% ; breadth, 5 line. 
Professor Hutton communicated my unique example. Hab. 
Queenstown, Otago. 
1390. Cyphon dilutus, n.sp—Narrow, oblong, sub-depressed, 
thickly covered with fine pallid hairs, almost wholly testaceous. 
Head rather broad proportionally, somewhat castaneous, its 
fine punctation. much concealed by the pubescence. Prothovax 
almost as wide as the elytra at the base, with blunt angles, 
distantly and minutely punctured. Elyiva parallel-sided, rather 
flat, but without obvious depressions, finely and distantly punc- 
tulated. Antenne robust, rather long, 3rd articulation half as 
long as 4th. 
Of remarkably elongate outline; cannot well be mistaken ; 
superficially resembling a small Mesocyphon, or Atopida testacea. 
Length, 1% ; breadth, ¥% line. 
I found one specimen only at Tairua. 
MELYRIDA, 
Arthvacanthus, n.gen.—Allied to Dasytes ; differing principally in 
the maxillary palpus terminating in a broad joint obliquely trun- 
cated at the extremity, and, thererore, sub-securiform ; and in 
the structure of the tarsi, the anterior having the basal joint 
-shorter than the 2nd, with a yellow spiniform protuberance close 
to its external apex ; the claws are not perceptibly appendiculate, 
though thickened at the base ; eyes large and prominent. 
1391. Arthracanthus planifrons, n.sp.—Sub-depressed, mode- 
rately elongate ; bluish, head and thorax darkest, elytra slightly 
infuscate, legs and four first antennal joints castaneous ; mode- 
rately glossy, clothed with fine cinereous hairs. 
Head rather broad, plane in front, distinctly and finely punc- 
tured, but densely and minutely sculptured on the occiput and 
near the eyes. Antenne longer than head and thorax, not serrate, 
4th joint just appreciably shorter than 3rd or 5th, 9th and toth 
distinctly expanded apically, sub-triangular, the terminal quite 
as long as its predecessor. Prothovax a little longer than broad, 
not so wide as the head, medially dilated laterally ; transversely 
impressed near base and apex, the sides and front most punc- 
tated, the basal sculpture similar to that of the occiput. 
Scutellum small, transversely quadrate. Elytva broader than tho- — 
rax, rugosely punctured. Legs elongate, the basal articulation of — 
the posterior tarsi longer than 5th. &
