Closely resembling X. nanuSy but tbe elytra decidedly more elliptical in 

 form, i.e. narrower at the shoulders and more regularly rounded on the sides, 

 the apex being jointly rounded ', the surface is of the coppery black or dark 

 brown of the full-coloured examples of X. nanus ; and the grey pubescence is 

 spotty in the same way on the elytra ; but the dark patches lie in two places, 

 forming irregular broad fasciae, one at the middle and the other at the apex. 

 The antennae are rather more slender, and have a larger portion of the apices 

 of the joints pitchy black. Beneath, the insect is more densely clothed with 

 grey pubescence. 



Christchurch {Mr. Fereday) ; one example. 



Xylotoles scissicauda, n. sp. 



X. elongato-ellipticus, castaneo-fuscus, griseo-pubescens j thorace medio 

 utrinque dilatato-tumido, supra sulcis duobus transversis fortiter impressis, 

 alteroque dorsali, basi subtiliter transversim multistrigoso j elytris humeris 

 paululum productis, obliquis, postice gradatim attenuatis, apice dehiscentibus 

 ibique sutura emarginata, supra fere ad apicem lineatim punctatis, costulisque 

 utrinque tribus. Long. 3 J — 4 lin. 



This very distinct species may be recognized at once by the thorax — tumid, 

 almost tubercular in the middle on each side, with the anterior and posterior 

 transverse sulci deeply impressed and united in the middle by a longitudinal 

 dorsal impressed line. The tubercle on each side is coarsely sculptured j and 

 the basal surface is covered with a multitude of fine transverse striae. The 

 punctuation of the elytra extends nearly to the apex, and is interrupted by 

 three raised costae on each elytron ; the apex is tapering, and the suture widely 

 gaping, having on each edge a curved sinuation. The sides and apex of the 

 elytra have a few whitish bristles. The legs are concolorousj the antennae 

 have a speckled pubescence and are robust. 



Christchurch {Mr. Fereday) j three examples. This species tends to 

 connect Xylotoles with Tetrorea. 



MiCROLAMiA, nov. gen. 

 Gen. Xylotoli affine ; differt antennis articulis brevibus, primo basi extus
