 E. oblongus, aureo-fulvus, squamoso-setosus, supra irregularis ; rostro 

 prothorace vix breviore, curvato, versus apicem gradatim crassiore, 

 rugoso-squamoso ; mandibulis nigris, bidentatis ; prothorace latitudine 

 longiore, basin versus majus tenuato, supra tricarinato, carina media 

 dimidio apicali limitata ; scutello nullo ; elytris ovalibus, basi arcuatis, 

 humeris elevatis, supra seriatim punctatis, interstitiis paucituberculatis, 

 tuberculis subfasciculatis ; pedibus rostroque setulis curvatis vestitis. 



Long., 2\ lin. 



Tairua. 



NOTE. The assigned habitat is a mistake. I sent several specimens 

 to Pr. Sharp from Tairua, but they were extracted from the decayed 

 root of a tree in the Domain at Auckland. 



765. E. SCalbiOSUS, n.s. Elliptical-ovate, rather broad, piceous, 

 rough. Rostrum stout, bicarinated ; the squamosity, though dense, is 

 most apparent in the form of four tufts near the scrobes and a dorsal 

 line behind. The thorax is sub-quadrate, rough, coarsely punctate ; the 

 disc bears a dorsal ridge which is obliquely furcated towards the base, an 

 entire oblique one near each side, and a curved marginal one, all of 

 which are densely squamose ; it is depressed at the base, which is 

 bisinuated and closely adapted to the elytra. The elytra are oviform, 

 with porrected humeral angles and sub-acuminate apex ; their sculpture 

 consists of large foveiform punctures irregularly disposed, except on the 

 abruptly declivous portion behind where the punctation is much finer 

 and placed along three fine striae ; the intervals between the discoidal 

 punctures are elevated, rugose, and crested with, in some places fuscous, 

 in others griseous, setulae ; there are also, on each elytron, a griseous- 

 crested humeral ridge, and several more or less distinct tubercles, and 

 the suture is broad and densely squamose. The legs are closely covered 

 with scales and setae ; the antennae and tarsi are ferruginous and finely 

 pubescent. 



Length, 2f lines. 



I cut one specimen out of the stump of a tree at Tairua. 



766. E. castanetlS, n.s. At first sight this species might be 

 mistaken for the preceding one ; the eyes, however, are smaller and less 

 prominent, the punctation of the thorax is much finer, and its colour is 

 dark-chestnut, with paler clothing. The elytra are rather narrow, their 

 sides sub-parallel but rough, the shoulders oblique, apex somewhat 

 produced ; each bears three well-defined strongly punctured sutural 

 striae, those beyond being interrupted and irregular ; the interstices are 

 irregular and somewhat tubercular, except near the apex ; the sutural 

 line and the more elevated parts are clothed with small reddish scales, 

 the humeral ridges and three tubercles behind are crested with griseous 

 setae. 



The basal depressions of the prothorax and elytra are well-marked 

 as in the preceding species. The structure of the antenna in both these 

 two species (E. scabiosus and the present one) is similar, resembling 

 that of the typical species.
