110 COLEOPTERA 



This species is abundantly distinct, and not likely to be confounded 

 with any of the foregoing, from all of which its oviform prothorax will 

 at once distinguish it. 



Length, 2 ; breadth, J line. 



I found my specimen in the forest near Whangarei Harbour.

Leach; Lacord. Hist, des Ins. Coleop., Tom. ii.,/. 80. 



Mentum very short. Ligula membraneous, moderate, rounded and 

 entire in front ; its paraglossse very much longer than it, acuminate, 

 ciliated inwardly. Labial /0#* filiform, their joints gradually increasing ; 

 the last of the maxillary more or less acuminate, of variable length. 

 Mandibles more or less elongate, acute, obtusely dentate in the middle. 

 Labrum transversal, emarginated in front, its edges membraneous and 

 ciliated. Head sub-orbicular or oval, provided with a moderate neck. 

 Antenna filiform, straight ; their basal joint moderately long, the last 

 hollowed at its apex, the others of variable form, partly moniliform. 

 Prothorax generally a little narrower than the elytra, rounded at its 

 base, truncated in front, with its anterior angles obtuse and depressed. 

 Elytra truncated posteriorly. Abdomen sub-parallel. Legs moderate ; 

 the intermediate sometimes approximated, sometimes rather distant ; 

 tibia spinous, save sometimes the anterior ; tarsi ciliated, the basal 

 joint of the four posterior a little elongated, the anterior occasionally 

 dilated among the males, sometimes simple in both sexes ; the four 

 posterior filiform. 



Body rather long, almost linear, or attenuated at both extremities, 

 frequently winged. 



204. P. impressifrons, n.s. Elongate, slightly convex; head 

 and thorax deep brilliant black ; elytra and abdomen somewhat bronzy- 

 black, the latter having the hind margin of its. segments pale brown ; 

 legs blackish-red ; antennae blackish, their three basal joints shining. 



Head about as long as broad, of a rounded contour ; with a curved 

 inter-ocular impression terminating behind at each end in a distinct 

 puncture, three punctures close to each eye, three or four more behind 

 them, and two smaller ones at its base. Prothorax a little longer than 

 broad, its sides nearly straight, so that the base and apex are of about 

 equal width, but the anterior angles being depressed give it, at first 

 sight, a somewhat different appearance ; on each side of the middle 

 there is a row of three or four obvious punctures, a second less regular 

 row beyond, but, in my only specimen, confused with a third quite 

 lateral row. Scutellum triangular, punctate. Elytra scarcely longer 

 than broad, widely emarginated at apex ; their punctation distinct, not 

 very close, and almost arranged in rows, with yellowish hairs arising 

 from the punctures. Abdomen moderately punctulated, clothed with a 

 few fine long yellowish hairs. Antenmc with three elongate-conical
