636 COLEOPTERA 



drical, the terminal joint sub-conical, acute ; eyes small, rather convex. 

 A/itciincF. slender, filiform, half as long as the body, alike in both sexes 

 in the majority of the species ; in some the fourth and fifth joints are 

 dilated among the males. Prothomx transversal, slightly narrowed in 

 front, apex truncate, lateral edges a little convex, the angles obtuse, the 

 anterior inflexed or bent inwards, the surface without depressions. 

 Sciitdliim often broader than long, triangular, somewhat rounded. 

 Elytra oblong-oval, more or less convex, sometimes oval and bulged, 

 or much elongated and depressed, with the extremity obtuse, and 

 irregularly punctured. Prostermim very narrow between the coxae, 

 almost dilated and prominent behind, leaving the cotyloid cavities 

 incomplete. Posterior y^;;/(?r^ strongly dilated, and attenuated at their 

 apex ; tihice depressed on the outside, not grooved behind, slightly 

 dilated at the extremity, which is rounded, and armed at the convex 

 edge with a small spur ; first joint of the tarsi measuring one-third the 

 length of the tibia, second very short, third bilobed, the fourth terminated 

 with simple claws. 



The New Zealand species placed, for the present, with this genus, 

 may be considered aberrant forms ; they belong, I think, to three 

 distinct genera, but I have not considered it advisable to make new 

 generic names for them, especially as only one or two examples of each 

 have been found as yet. 



1 1 16. P. rugulosa, n.s. Oviform^ a little convex, testaceous- 

 brown, rather dull. Antoum inserted between the eyes, separated by 

 a carinated interval ; they are filiform, eleven-jointed, the basal joint 

 almost pyriform ; second about half the length of the first, oviform ; 

 third longer than second, thickened at apex ; joints four to eleven 

 each shorter but more dilated than its predecessor ; the apical joints 

 much darker in colour than the basal ones. Head punctate. Frothorax 

 transverse, moderately convex, finely margined laterally and a good 

 deal rounded, base and apex truncate, its surface coarsely, closely, and 

 somewhat rugosely punctured. ScuteUiiin small. Elytra margined, a 

 little convex, oviform, widest behind the middle, a good deal narrowed 

 in front, and regularly rounded ; there is an obvious humeral elevation 

 on each, and their whole surface is rather coarsely, closely, and rugosely 

 punctured. Legs moderate ; the posterior femora moderately inflated ; 

 tibia, straight, gradually dilated towards the apex, apical spur indistinct; 

 tarsi not so long as the tibiae, their basal joint scarcely a third of the 

 length of the tibia (those of the two front pairs shorter), the second joint 

 shorter than first, triangular ; third bilobed. 



The body is destitute of pubescence, but the tibise bear fine hairs. 



Length, i line. 



I found two examples only at Tairua. 



1 1 17. P. nitida, n.s. Oval, of a shining bronzy-black colour, the 

 tibise brownish, antennpe infuscate, the basal joints paler than the apical ; 

 body convex. 



Head pilose in front, the space between the antennae not much 

 elevated but shining, with a few punctures behind the eyes. Antennce
