234 COLEOPTERA 



in front of the base, the sides in front nearly straight but converging 

 towards the constriction, the lateral margins are well-defined and some- 

 what roughened ; there are two longitudinal costse near the middle, the 

 surface is very uneven, the anterior portion being distinctly punctate, 

 and the posterior constriction forms a very evident transverse depres- 

 sion near the base. The elytra are much wider than the thorax, widest 

 near the middle, narrowed in front, a little depressed transversely before 

 and behind the middle ; they bear punctured striae arranged in pairs by 

 the intervening costse, having very much the same appearance as those 

 seen in L. sculpturatus, but not quite so much elevated. 



The antenna are not so long as the head and thorax, with a very 

 thick basal joint, the second stout, oval, joints three to eight rather 

 elongate and slender, club elongate, its terminal joint distinctly larger 

 than the ninth or tenth. 



Length, nearly i line. 



I found two examples near Whangarei Harbour. 



412. L. COStulatllS, n.s. Castaneous, moderately shining, head, 

 legs, and antenna reddish, the latter rather short, with a proportionally 

 short club. 



Head rough, with some indistinct irregular lines. Prothorax oblong, 

 constricted and depressed in front of the base, with roughened margins, 

 two distinct longitudinal costse near the middle, and an abbreviated 

 curved one near each side, and the rest of the surface rather rough. 

 Elytra ovate, widest rather behind the middle ; they bear four pairs of 

 punctured strise, the suture is a little elevated, and each elytron has 

 three well defined costse of which the innermost only reaches the apex, 

 these costae are nearly equally elevated throughout. Tarsi slender. 



Length, nearly i line. 



Described from one example found at Tairua. 



413. L. fLoridUS, n.s. Robust, reddish, shining, thorax and 

 antennal club darkest, elytra castaneous-red. Head punctate, with two 

 indistinct elongate impressions in front. Prothorax oblong, a little 

 constricted behind, transversely depressed near the apex, much more so 

 near the base, rather rough and dull, distinctly punctured, with an 

 abbreviated elevation near each side at the middle. Elytra oblong- 

 oval, convex, slightly depressed in front of the middle, with an obtuse 

 elevation at each shoulder ; they bear shallow, but distinctly punctured 

 strise, and are almost destitute of pubescence. Antenna as long as head 

 and thorax, the third joint small, club rather short. 



Length f line. 



I found one individual at Whangarei Heads.

Nearly allied to Lathridius, differs as follows : Mandibles horny, 

 bifid at their extremity, the latter preceded by three or four small
