734 COLEOPTERA 



Elytra sub-parallel, with simple apices, punctate-striate, interstices punc- 

 tulate but not rugose; the grey hairs with which they are clothed are 

 slender, decumbent, and, though elongate, not very easily seen at first 

 sight, but the yellow pubescence is quite distinct. Antenna pubescent, 

 rather slender; the second joint of the funiculus a little longer than the 

 third. Tarsi stout, their third joint bilobed. 



A pretty little Cossonid, allied to P. planiuscula. 



Length, \\ ; breadth, quite \ line. 



I found one specimen only at Tairua some years ago. 



1303. P. rugirostre, n.s. Body almost opaque, convex, sub- 

 cylindrical ; piceous ; legs and antennae reddish ; sparsely and minutely 

 clothed. 



Rostrum robust, rather broad, plane, gradually narrowed towards its 

 apex, so punctured as to appear longitudinally rugulose. Eyes pro- 

 minent. Head not smooth behind. Prothorax ovate-triangular, con- 

 stricted in front, its hind angles but little rounded ; its surface is closely, 

 coarsely, and somewhat rugosely punctured, and bears some fine, short, 

 yellow hairs, not visible when viewed with an ordinary glass. Sculellum 

 depressed, impunctate. Elytra cylindrical, with simple apical margins, 

 almost crenate-punctate-striate, interstices punctulate, appearing rugu- 

 lose ; with rows of very short, erect, yellow hairs or fine setae. Antennce 

 rather short and stout; basal joint of funiculus stout, second a little 

 longer than third; club ovate. Tarsi stout, the third joint nearly entire. 



Quite a distinct form ; differentiated from the orthodox Pentarthra by 

 its broad snout, gradually narrowed towards the apex ; the thorax seems 

 rough, but the sculpture of the beak and elytra, though evident enough, is 

 rather shallow. 



Length, i| ; breadth, nearly line. 



Described from one individual (male) taken at Parua. 



1304. P. ruficorne, n.s. Robust, sub-depressed, not parallel, 

 apparently nude, yet in reality sparingly clothed with scarcely-visible, 

 minute, slender grey hairs; rather dull, pitchy-black; tibiae, tarsi, and 

 antennae dark-red. 



Rostrum stout, rather broad, parallel, its punctuation coarse but 

 shallow, the intervals between the punctures densely but finely sculp- 

 tured, causing it to appear dull. The antennae are implanted just before 

 the middle of the beak, are unusually stout, the scape a good deal in- 

 crassated ; second joint of the funiculus slightly longer than third ; club 

 short. The head is perceptibly separated from the smooth neck by a 

 deep linear impression continued downwards just behind the back part of 

 the eyes ; these latter are small, quite lateral, and by no means prominent. 

 Prothorax large, considerably longer than broad, gradually narrowed 

 anteriorly, its frontal constriction continuous, forming an obvious curved 

 depression ; behind the constriction it is depressed longitudinally, with 

 a smooth linear space on the middle ; the rest of its surface is moderately 

 closely and distinctly punctured, its apex more finely and densely, and 

 the spaces between the punctures are finely and closely impressed. 

 Scutellum smooth. Elytra gradually narrowed posteriorly, apices
