OF NEW ZEALAND. 655 



The only exponent of this genus should, I think, be placed near 

 Abaris in the Anchomenida ; it has quite the facies of zFerom'a, but differs 



structurally. 



1144. P, atratus, n.s. Body oblong-ovate, broad, sub-depressed, 

 widest behind the middle of the elytra; shining, quite black, legs 

 piceous, tarsi and antennae (save the pitchy basal joint) rufous. 



jffeadwiih. two irregular frontal foveae not extending beyond the inter- 

 antennal line, slightly wrinkled, narrowed behind the legs. Prothorax 

 transversely quadrate, rounded laterally, narrowed between the middle 

 and the almost rectangular hind angles ; apex truncate, base triangularly 

 excised at the middle ; the thick rims least distinct behind ; the sides, 

 particularly behind the middle, explanate ; the basal fossae are large, their 

 outer slope on the same plane as the flattened angles ; the dorsal groove 

 terminates in a deep, curved, frontal impression. Elytra broader and 

 about twice as long as the thorax, very gradually rounded to beyond the 

 posterior femora, and from thence considerably narrowed sinuously to the 

 apices, which, though somewhat pointed, do not protrude further than the 

 extremity of the abdomen ; the disc is almost (transversely) flat ; each 

 elytron has eight distinct, impunctate striae, the fifth and sixth abbreviated 

 and confluent ; the interstices are scarcely convex, and, with the excep- 

 tion of the external one, quite impunctate ; besides the above-mentioned 

 there are short scutellar striae, one on each, and another between the 

 lateral row of punctures and the side margin. 



Under-side pitchy-black ; mesosternum very perceptibly punctured ; the 

 four anterior coxa: and thighs bear many yellow bristles ; tibia densely 

 clothed with yellowish hair-like spines. 



The thorax, when viewed from above, will be seen to be broadly and 

 peculiarly depressed near the hind angles ; when looked at from the side 

 the sides will appear as if gradually raised from the middle backwards, so 

 that the posterior angles are nearly on the same plane as the more 

 elevated parts of the disc. The elytra are but slightly narrowed anteriorly; 

 their greatest width is behind the posterior femora (3* lin.), but the apex 

 is not one line in breadth. 



Length, 9 lines; breadth, y s . 



I found only one specimen at Parua, near Whangarei Harbour, and 

 that, unfortunately, is very much mutilated. 



Tropopterus (P. 27). 



1145. T. patulUS, n.s. Body moderately convex; elytra very 

 broad; shining, pitchy-black above; the labrum, antennae, legs, and the 

 elytral margins and suture rufescent ; palpi castaneous. 



Head narrowed anteriorly ; the frontal depressions broad, separated 

 from the eyes by a slightly raised interval, which again is marked off 

 by a narrow groove close to each eye, the two inner united in line with 

 the antennse by means of a transversal line. The two basal joints only of 

 the antennae are nude. Prothorax transverse, somewhat elevated, cordi- 

 form, base and apex sub-truncate, sides regularly rounded, narrowed but 

 not sinuated behind, the posterior angles not at all protuberant, the lateral 

 rims fine but distinct ; it shows a fine dorsal line, is somewhat depressed 

 along the base, and has broad, shallow foveae prolonged forwards as
