OF NEW ZEALAND. 499 



This and the preceding are very short thick-set species, the former, 

 inter alia, readily distinguished by its very convex elytra. It is very 

 likely that both have the transverse ridge, formed by the sudden constric- 

 tion of the anterior portion of the prothorax, tufted as in the following 

 species, but not very marked in T. gibbus ; probably a good deal 

 depends on age. 



NOTE. There is hardly any indication of the tufted transverse ridge 

 in either of these two species, the apex only bears erect scales. 



887. T. densus, n.s. This species closely resembles T. ferrugatus, 

 but is larger and broader, with more elongate antennae. The general 

 ground-colour is piceous ; the clothing, which is rather dense, consists 

 of elongate white and yellowish scales, those of the latter colour being 

 chiefly confined to the anterior portion of the thorax, where they assume 

 the form of tufts, and the base and margins of the elytra. The rostrum 

 in front is finely punctulated, behind grooved and carinated, the grooves 

 are coarsely punctured, but the punctation is partially concealed by 

 griseous scales. The thorax is of the normal form, the posterior portion 

 being of the same width as the elytra, the anterior abruptly contracted 

 so that it becomes almost as narrow as the head ; the sides are rounded 

 towards the base, those of T. ferrugatus being straight, and the base has 

 a more prominent central lobe than that species ; the surface is punc- 

 tate and squamose. The elytra are convex, abruptly deflexed poste- 

 riorly ; the sides are vertical and straight to beyond the hind thighs, 

 from this point they are suddenly contracted, so that the apex has a 

 strongly lobed appearance ; each elytron bears seven rows of very large 

 oblong punctures. The legs are pitchy-red, and clothed with setulae. 



Length, 3 lines (rost. excl.) ; breadth, nearly if. 



I found two examples of this species at Whangarei Heads. 



888. T. verruCOSUS, Pascoe; Ann. Mag. Nat. Hist., July, 1876. 

 T. ovatus, niger, subfusco-squamosus ; rostro modice arcuato, prothorace 

 vix breviore ; antennis ferrugineis ; funiculo articulo secundo quam 

 primo paulo longiore ; prothorace subtransverso, pone apicem modice 

 constricto, apice ipso bifasciculato, in medio transversim quadrifasci- 

 culato ; elytris brevibus, convexis, substriato-punctatis, tuberculis fasci- 

 culatis dispersis, postice declivibus ; femoribus infra dente parvulo 

 instructis ; tibiis breviusculis. 



Long., 3 lin. 



Tairua (Capt. Broun). 



NOTE. The oblique tubercular line, extending from the shoulder to 

 the suture, bears pale-rufous erect scales, as do a few of the other 

 tubercles ; the size given is exclusive of the rostrum, but most specimens 

 do not exceed two lines in length. The three species are rare, T. ferru- 

 gatus most so. 



Sympedius.
