1326 COLEOPTEKA 



in front and behind ; dorsal groove broad and deep, barely touching 

 the basal margin ; basal fossae large, placed nearer the sides than 

 the middle, and with an indistinct smaller impression beyond. Elytra 

 strongly sinuously contracted behind, apices broadly rounded, the sides 

 a little "narrowed towards the base ; each elytron with eight series 

 of elongate impressions, the external marginal, these impressions 

 irregular, and, more or less, united longitudinally by slender, linear, 

 interrupted striae, the sculpture more indefinite behind ; interstices 

 slightly uneven and feebly wrinkled. 



Femora and trochanters deeply rugose ; the sternum finely 

 wrinkled ; hind thighs inflated, but not angulate below. 



Thorax with five or six lateral setae, its side-margins thick and 

 subcrenate. Humeral angles obviously dentiform. Terminal seg- 

 ment of the abdomen strongly sinuate at each side, obliquely trun- 

 cate towards the middle, with three hispid punctures at each side of 

 the middle. 



P. irregidaris is the only near ally. 



9 . Length, 9 ; breadth, 3 lines. 



Hastwell, Napier. One, found by Mr. H. Suter. 



2332. P. edax, n-s- Brilliant, black, tarsi and antennae 

 nigro-piceous, palpi paler. 



Head with uneven, obsoletely-punctured frontal impressions. 

 Eyes prominent. Thorax one-seventh broader than long, apex sub- 

 truncate ; its sides moderately regularly rounded, but with a slight, 

 though not short or abrupt, sinuation towards the rectangular pos- 

 terior angles, the base and apex of nearly equal width ; the surface 

 somewhat convex and uneven, with shallow transversal striae, a 

 curved frontal impression, and a fovea-like one near each anterior 

 angle ; dorsal furrow barely reaching the apical margin ; basal foveae 

 large, situated midway between the middle and the sides, sub- 

 punctate or rugose, each with a narrow elongate one beyond, sepa- 

 rated from the lateral margin by a raised space ; base incurved 

 medially. Elytra oblong, the sides slightly curved and narrowed 

 towards the moderately dentiform shoulders, strongly sinuate 

 apically ; finely irregularly striate, the punctuation fine but distinct, 

 the sculpture ill-defined behind, the surface there uneven; interstices 

 impunctate, slightly convex, the second narrowed near the middle 

 with a corresponding enlargement of the first and, third, the sixth 

 more or less catenulate, the seventh a little more elevated towards 

 the base than the others are ; the sutural striae become obsolete 

 near the base and bend outwards, so that the second interstices are 

 much narrowed there ; the other striae converge by pairs, and become 

 indistinct, towards the base ; the scutellar striolae are represented by 



Eunctures. Legs simple ; hind thighs not much inflated, not angu- 

 ite below. 



This is a rather distinct species, so far as I can judge by the 

 example before me. 



Scutellum smooth where visible. Thorax with two setae on each 

 side, one at the hind angle, the other before the middle but duplicate
