COSSONIDAK. 247 



Rostrum half the length of the thorax, subparallel, broad, slightly 

 impressed along the middle, moderately coarsely but distantly punctate 

 behind, more finely in front, longitudinally rugose at the sides; occiput 

 with a few fine punctures. Thorax slightly convex, ovate-triangular, 

 very little longer than broad, slightly constricted in front, somewhat 

 contracted at the base; disc moderately coarsely but not closely punc- 

 tured, moir closely and i-ugosely at the sides, the apex nearly smootli. 

 Scutellum distinct. Elytra hardly wider than the thoi'ax at the base, 

 scarcely double its length, their sides not quite straight, gradually 

 nan-owed i^osteriorly, Avith simple apices; they are distinctly substriat^- 

 punctate, quite striate behind; interstices with fine serial jjunctures and 

 very slightly rugose; on each shoulder, above, there is a minute swelling 

 tliat can hardly be called a nodule. 



Scape straiglit, medially inserted, very short, gradually incrassate; 

 2nd joint of funiculus shorter than the 1st, yet rather longer than the 

 following ti-ansverse ones; club rather short, ovate. 



Legs sliort and stout; penultimate tarsal joints excavate aljdve but 

 not lobed. 



Wollaston's /''. scrtcatum, 905, wliicli I have not seen, is differentiated 

 by its subcylindrical form and subopaque pale rufescent surface. This 

 species is distinguishable from liis P. zealatidicum by its shorter and paler 

 body, more triangular and less constricted thorax, and manifestly shorter 

 legs and antennae.

Elongate, subparallel, suljdepressed, slightly nitid; dark lufo- 

 oastaneous, antennae and tarsi of a ligliter hue; sparingly clothed with 

 slender, decumbent, inconspicuous, greyish-yellow pubescence. 



Rostrum shorter than the thorax, broader near the front than behind, 

 slightly dilated at the point of antennal insertion, just before the 

 middle; finely and irregularly but not closely punctate. Head narrowed 

 anteriorly, not elongate, rather more distinctly punctured, the occiiDut 

 included, than the rosti'iun. Thorax a third longer than broad, dis- 

 tinctly constricted near the apex, its sides nearly straight, but some- 

 what curvedly narrowed near the ])ase; its surface only moderately 

 coarsely and closely ])unctured, fess closely along the middle, which is 

 Hattened or feebly impressed. Scutellum small, yet (juite distinct. 

 Elytra twice the length of the thorax, hardly as broad as it is, truncate 

 at the base, gradually narrowed behind the middle, with simple apices; 

 tliey are distinctly and regularly striate-punctate, the interstices ai"e 

 moderately narrow, with indistinct serial jTunctures, and appear slightly 

 rugose. 



Legs elongate yet stout, tibiae distinctly pubescent near the extremity; 

 tlie lobes of the penultimate tarsal joints all well developed. 



Antennae elongate; scape slightly curved, gradually ino-assate; 2nd 

 joint of the fiiniculus of about the same lengtli as the basal, 3rd quite 

 as long as broad, 5th transverse, rather sliorter and broader than its 

 predecessor ; club rather narrow and elongate, its apical articulations 

 small, witli fine pubescence. 



When compared with the same sex of T. aiu/usfd, 1626, this is seen 

 to have rather more slender antennae, with an evidently narrower club,
