480 COLEOPTERA 



The insect closely resembles P. sulcatus, with a rather shorter but 

 similarly rugosely sculptured rostrum : the thorax is somewhat longer, 

 so that it is less abruptly narrowed in front ; its base is sub-truncate and 

 depressed, and its sculpture consists of shallow rugose punctures. The 

 elytra are similar in form to those of F. sulcatus, their anterior portion is 

 rugosely sculptured with granular elevations, but behind they bear 

 coarsely punctured striae ; the sutural costa is dilated a little before the 

 middle and there bears a very evident horn-like process, the second is 

 distinctly elevated near the apex only, the third is very little raised in 

 front and terminates at the middle in a tubercular elevation somewhat 

 similar to that on the inner ridge, but situated a little further back, the 

 outer are merely granulated intervals between the stride, which are 

 punctured near the apex only. Prosternum rather deeply hollowed. 



Length, 4 lines (rost. inch). 



Described from a single specimen found by Captain Hutton at 

 Martyn's Bay, on the west coast of Otago. 



849. P. barbifrons, White ; Voy. Er. Terr., Ins., p. 15. Beak 

 with two longitudinal rows of ferruginous hairs on the margin directed 

 forwards ; thorax thickly punctured ; elytra narrower than in P. sulcatus, 

 with eight longitudinal stripe, the intervening spaces flat at the base, two 

 of these at the tip raised and crested with light brown scales ; whole 

 insect deep brown, mixed with lighter coloured scales. 



Length, 4 lines.

Note. — This and the preceding species occur near Auckland. 



850. P. punctulatus, n.s. Head and rostrum reddish-brown, 

 punctate, with an elongate depression on the vertex. Thorax mode- 

 rately constricted in front, the surface densely punctured, and bearing a 

 few griseous scales. The elytra are punctato-striated, only six stria? 

 distinct, the basal portion is rugosely granulated, the remainder punctu- 

 late ; the interstices are broad, particularly near the base, the sutural 

 narrowest ; the second, which is the most elevated, bears a row of six 

 small tubercles, which, though present on the others, are very indistinct; 

 the first, third, and fifth are crested with griseous setje behind, and are 

 bent at the end. Under-side punctate and pilose. Legs and tarsi 

 normal. 



Length, 3f lines.

851. P. rostralis, n.s. Obscure ferruginous, antennae and tarsi 

 clear red. Rostrum rather long, shining, finely punctured, with a smooth 

 impressed line in front ; the head is strongly punctured, the intervals 

 rugose, with a slight depression on the vertex ; it bears a few griseous 

 scales. Thorax slightly constricted in front, very like that of P. barbi- 

 frons; except a smooth space on the disc, closely and coarsely punc- 

 tured. The elytra obovate, with rectangular apices, bear six distinct 

 striae not very deeply punctured ; the interstices are nearly straight.
