464 COLEOPTERA 



I have received this curious species sparingly, both from Mr. Lawson 

 and Captain Broun. 



N.B. — I am not acquainted with the species of Stephatwrhynchiis just 

 described by Mr. Pascoe, but a specimen of the present insect which I 

 sent to him was remarked on as "very distinct." 



Note. — I have got this species at Auckland, Tairua, and Whangarei 

 Heads. 



824. S. craSSUS, n.s. Short, broad, convex, and robust, clothed 

 with pale-fuscous and grey scales, with a darker dorsal line on thorax 

 and elytra. Antennce. stout, fuscous, pubescent ; the first joint of the 

 funiculus is longer and stouter than the second, which is longer than 

 any of those that follow ; club rather short, ovate, not acuminate. 

 Rostrum thick ; head dilated behind the eyes and constricted behind, 

 with an impressed line from the occiput to the point of insertion of the 

 antennae ; eyes prominent and coarsely facetted. 



Thorax conical, with sinuous base and truncate apex, slightly con- 

 stricted in front, the sides nearly regular. 



Scutellum sub-oblong. Elytra scarcely twice the width of the thorax 

 at the base, sub-cordate, short, with prominent but rather obtuse 

 shoulders, rounded sides and apex ; they bear indistinct rows of punc- 

 tures, a prominent, curved elevation on each near the middle, about 

 midway between the side and suture, which becomes obsolete towards 

 the base, but bent behind towards its fellow, though not reaching the 

 suture ; the rest of the surface is uneven and tubercular. The legs are 

 rather short and stout, the anterior femora are flexuose and almost 

 obtusely dentate, the other four being more inflated, and armed below 

 with a large, acute, laterally compressed tooth ; the tibiae are arcuated, 

 the posterior most so ; the tarsi are stout, the two basal joints sub- 

 triangular, the penultimate bilobed and widened, the apical elongate. 



The colour is somewhat variable ; in some examples the legs are 

 pale rufo-fuscous, the tibiae being sub-annulated with fuscous and grey, 

 but the discoidal clothing of the elytra and the dorsal thoracic line, in 

 four out of five of my specimens, are of the same dark rich brown 

 colour, the carinated portions of the elytra being rendered obvious by 

 the presence of pale, almost white, scales. 



Length, if to 2\ lines. 



I found this species at Tairua. The species might become the type 

 of a new genus. 



Pactola. 



Pascoe; Ann. Mag. Nat. Hist., Jany., 1876. 



Rostrum capite brevius, cylindricum ; scrobes obliquje, infra oculos 

 desinentes. An ten nee subterminales ; scapus elongatus, pone oculos 

 superans ; funiculus 7-articulatus, articulo primo majusculo, quatuor 

 ultimis transversis; clava magna, ovata, concreta. Oculi prominuli, 

 laterales, rotundati, grosse granulati. Prothorax angustus. Elytra 

 ampliata, supra irregularia, humeris callosis. Pedes quatuor anteriores
