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 costas 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 concolorous ; the antennse have a speckled pubescence and 

 are robust. 



Christchurch [Mr. Fereday) • three examples. This species 

 tends to connect Xylotoles with Tetrorea. 



MiCROLAMiA, nov. gen. 



Gen. Xglotoli affine ; differt 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, hnmeris rotun- 

 datis. Thorax magnus, lateribus tumidis. Mesosternum brevis-, 

 siuiuni. Pro- et mesostema inter coxas latissima, plana. 



Microlamia pygmcea, n. sp. 



M. elongato-ovata, rufo-castanea nitida, antennis pedibusque palli- 

 dioribus, illis undique pilosis; capite punctato; thorace lateribus 

 grossissime punctatis, disco lasvissimo, sine linea dorsali, basi et 

 apice transversim strigoso ; elytris sparsim, basi densius punc- 

 tatis, apice snbabrupte declivibus. Long. 1^ lin. 



This curious and minute Longicorn in the proportions of 

 its body resembles the genus Deucalion rather than Xylotoles ; 

 but the thorax is unarmed at the sides. The basal joint of 

 the antennas forms a pyriform club, as in the genus Blax. Its 

 chief peculiarities reside in the great width of the pro- and 

 mesosterna between the coxas, and in the very thick clavate 

 thighs, also in the robust filiform antennas — not ciliated, but 

 hairy on all sides, and with rather short joints, the third and 

 fourth not much longer than the rest. 



Auckland [Mr. Laivson) ; one example. 



Somatidia, Thomson, Syst. Ceramb. p. 39. 



Gen. Parmenai affine ; differt thorace haud armato, femoribusque 

 fortiter clavatis basi pedunculatis. Corpus ovatum, grosse punc- 

 tatum. Caput inter antennas haud concavum. Antenna', filiformes, 

 ciliatae ; scapo ovato, articulo tertio cseteris paulo longioribus. 

 Prosternum inter coxas arcuatum. Mesosternum oblongum, de- 

 clive. Epimera mesothoracica obliqua, acetabula haud attingentia. 

 Tibiae intermedia) extus emarginatae. Ungues divaricati. 



Closely allied to the Mediterranean genus Pam/ena, and
