Closely resembling X. nanus > but the 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 antennse 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 ; thorace medio 

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

 alteroque dorsali, basi subtiliter transversim multistrigoso ; elytris humeris 

 paululum productis, obliquis, postice gradatim attenuatis, apice dehiscentibus 

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



utrinque tribus. Long. 3| — 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 ; 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

The legs are concolorous; the antennae 



have a speckled pubescence and are robust. 



Christchurch (Mr. Fereday) ; three examples. This species tends to 



connect Xylotoles with Tetrorea. 



Microlamia, nov. gen. 

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

 haud subito dilatato, femoribusque fortiter tumido-clavatis. Corpus minimum, 

 longe hirsutum ; elytris quam corpore anteriore haud longiore. Elytra basi 

 transverse depressa, humeris rotundatis. Tliorax magnus, lateribus tumidis. 

 Mesosternum brevissimum. Pro- et mesostema inter coxas latissima, plana.
