Broun. — Neiv Genera and Species of Coleoptera. 437 



In shape intermediate between the elongated M. oblongus (656) and 

 .1/. thoracicus (662) and the series of more thickset species, such as M. 

 crassus, but separable from these by the linear impression across the 

 base of the thorax. 



Length 3^ mm. ; breadth, U- mm. 



Erua. Unique. January, 1910. 



Group Helopidae. 



3254. Adelium complicatum sp. now Adeiium Kirby, Man. N.Z. 



Coleopt., p. 386. 



Elongate, subdepressed, glabrous, nitid; nigro-violaceous, legs inclu- 

 sive; antennae and palpi fuscous; labium fusco-rufous. 



Head uneven, irregularly and coarsely punctured, somewhat depressed 

 and coarsely rugose between the eyes. Thorax distinctly margined, a 

 third broader than long in the middle, its sides slightly rounded from 

 the obtuse front angles backwards, but near the base moderately narrowed 

 and nearly quite straight, with rectangular angles; disc with a median 

 linear impression from base to apex but not sharply defined, basal fossae 

 somewhat indefinite and situated nearer to the sides than the middle; 

 its punctation moderate and irregular; there are several slightly raised 

 and depressed spots which cause the surface to appear uneven; the base 

 and middle of the apex are nearly truncate. Scutellum subquadrate, 

 transverse. Elytra more than double the length of thorax, slightly 

 broader than it is at the base, nowhere more than a half broader; the 

 shoulders strongly margined and a little curvate; they are gradually 

 narrowed behind the posterior femora; their sculpture is complex, con- 

 sisting of smooth, longitudinal, linear and irregularly curved elevations 

 and minutely punctate intervals. 



Tibiae stout, curvate externally, the anterior most so near the ex- 

 tremity, the posterior above the middle, but below that part slightly 

 twisted and laterally compressed. 



The general contour is intermediate between the parallel-sided series, 

 such as A. Zealand iciim, and the broader A', bullatum, with the base of 

 the thorax resting on the elytra. A. gratiosum (2055) is a much larger 

 insect. In A. bullatum the elytra! sculpture consists, to a great extent, 

 of oviform elevations; these are not smooth, being more or less distinctly 

 punctate. 



Underside piceous, feebly rugose, basal ventral segment very broadly 

 rounded between the coxae. 



Length, 14 mm. ; breadth, 4£ mm. 



Greymouth. Unique. Secured by Mr. J. H. Lewis over a year ago. 



3255. Cerodolus curvellus'sp. nov. Cerodolus Sharp. Man. N.Z. Coleopt. 



p. 1161. 



Elongate-oval, moderately convex, glabrous, nitid ; nigro-aeneous, 

 elytra somewhat iridescent, the legs, antennae, and palpi rufo-castaneous. 



Head finely punctate, rather more distantly behind than in front; 

 antennary orbits almost fiat. Thorax fully a third broader than long, 

 base distinctly bisinuate, its sides finely margined and gently curved, 

 front angles rounded, the posterior obtusely rectangular; disc finely 

 yet quite definitely but not closely punctured, and with a slight basal 

 depression between the middle and each side. Scutellum short and
