second joint subovate, third decidedly longer than fourth, the latter 

 and fifth are small, the sixth cup-shaped. The second joint of the 

 maxillary palpi is not so long as the third and fourth conjointly, 

 flexuose, and the fourth is a good deal shorter than the third. Head 

 obtusely rounded, the epistome feebly emarginated in front, almost 

 truncate, its surface moderately and closely punctured, and with a pale 

 brown spot on each side in front of the eyes. Thorax margined, trans- 

 versal, somewhat hollowed in front near each side, rounded laterally 

 towards the front, with its surface finely punctured. Scutellum trian- 

 gular, punctated. Elytra finely margined, about three times longer 

 than thorax, each with a sutural stria from near the middle to the apex, 

 their punctation very similar to that of the thorax. Tarsi elongate, 

 the second joint of the posterior nearly as long as the next two ; inner 

 side of tibiae slightly grooved near the edges. 



Mesosternal process very narrow, elevated, and nearly vertical in 

 front ; the metasternum is obtusely elevated on the middle, its central 

 portion smooth and shining. Under-side more or less finely sculptured 

 and densely clothed with short cinereous hairs.

There is a paler variety less common than that described above. I 

 found the species in different localities. 



146. P. yariolorum, n.s. Of the same form as P. tritus, 



moderately shining, brownish-testaceous, the labrum, head between 

 the eyes, and the thoracic disc, dark-brown ; and the discoidal por- 

 tion of the elytra more infuscate than the marginal; legs and 

 antennae somewhat testaceous, the tarsi, palpi, and all but the club of 

 the antennae reddish-testaceous. Head finely punctured, with two 

 distinct oblique lines converging towards the middle. Thorax trans- 

 versal, with the front and hind angles rather less prominent than in 

 P. tritus, and the sides more rounded behind ; its surface is finely 

 punctured. Scutellum triangular, punctated. Elytra moderately 

 closely punctured, with a sutural stria on each from the apex to the 

 middle, and several rows of large, shallow, rounded impressions, which 

 become smaller towards the apex, giving the elytra the appearance of 

 being pitted as with small-pox.

I found my specimen near Whangarei Heads.

Body convex, oval or oblong, with the head deflexed. Mentum sub- 

 quadrate, its sides nearly straight, oblique towards the front, and emar- 

 ginated at apex. Palpi stout ; the labial short, with their two last joints 

 about equal ; the maxillary moderately long, their last three joints sub- 

 cylindric, a little incrassated towards the apex, particularly the second, 

 nearly equal to one another, the terminal joint obtuse at apex. Antennae 

 nine-jointed, the first five joints cylindrical; the basal stout, nearly twice
