382 COLEOPTERA 



Length, if lines. 



I found two specimens at Whangarei Heads. 



682. L. crassicomis, n.s. This species is larger and more 

 robust than either of the preceding ones, of nearly the same colour, 

 being castaneous, with brownish-yellow legs and pitchy-red antennae. 

 Head piceous, its sculpture consisting apparently of shallow punctures 

 and minute granular elevations, so that it has a slightly rugose or 

 roughened aspect ; the antennal orbits are considerably elevated, and 

 curvedly prolonged inwardly, so that but a small space intervenes 

 between them in front ; the eyes are distinct, being a little more convex 

 and granular than in the typical species. Prothorax transverse, shorter 

 than that of L. priscus ; the apex is truncate, the sides rounded, with a 

 very slight sinuation behind, the margins are a little explanated, and the 

 posterior angles are rectangular ; the disc being rather convex gives a 

 somewhat depressed appearance to the sides and base, and the surface 

 is closely punctured. Scutdlum transverse, rounded, punctulate. Elytra 

 transversely convex, margined, and moderately closely but not coarsely 

 punctured, the punctation becoming finer posteriorly, and having on 

 the discoidal space a very slightly rugose appearance ; they are scantily 

 clothed with fine, short, yellowish hairs proceeding from the punctures. 

 Legs proportionally stout, the tibia inwardly armed at the apex with a 

 minute spine. 



The antennae are about twice as thick as those of the previously 

 described species, and distinctly pubescent ; the second joint is rela- 

 tively small ; third longest and almost obconical ; joints five to eight 

 decrease in length only ; the ninth and tenth are transverse and much 

 larger than the contiguous ones, the terminal joint being large but not 

 quite circular. Apical joint of maxillary/^/ large, quite securiform. 



Length, 2i ; breadth, line. 



I found one example only, quite recently, at Parua Forest, near 

 Whangarei Harbour. 



Arthopus. 



Sharp; Ent. Mon. Mag., September, 1876. 



Antenna, n-articulatse, clava triarticulata. Palpi maxillares articulo 

 ultimo haud incrassato, quam 3 duplo longiore. Tarsi subtus parce 

 pilosi. Facies fere generis Phyllodectce ( Phytophagarum). 



Antenna with the three apical joints thickened so as to form an 

 elongate club. Maxillary palpi with their basal joint very small, second 

 short, slender at the base, broad at the extremity, third slightly shorter 

 than second, about as long as broad, fourth joint about as broad as 

 third, quite twice as long as it, rather thicker in the middle than at the 

 apex. Head rather small, inserted in the thorax as far as the prominent 

 eyes, which are somewhat oval in form ; insertion of antennae not 

 concealed and quite contiguous with the eye. Front coxa rather widely 

 separated, the process between them not prolonged behind. Middle 

 coxae hardly more distant than the front pair, their trochantins visible ; 

 suture between meso- and metasterna very evident, extending just
