326 Transactions. — Zoology. 



This curious and minute Longicorn in the proportions of its body resembles 

 the genus DeitcaUon rather than Xylotoles ; but the thorax is unarmed at the 

 sides. The basal joint of the antennae forms a pyriform club, as in the genus 

 Blax. Its chief peculiarities reside in the great width of the pro- and 

 mesosterna between the coxae, and in the very thick clavate thighs, also in the 

 robust filiform antennae — not ciliated, but haiiy on all sides, and with rather 

 short joints, the tliird and fourth not much longer than the rest. 



Auckland {Mr. Lawson) j one example. 



SoMATiDiA, Thomson, Syst. Ceramb. p. 39. 



Gen. ParmencB affine ; differt thorace hand ai-mato, femoribusque fortiter 

 clavatis basi pedunculatis. Corpus ovatum, gi'osse punctatum. Caput inter 

 antennas hand concavum. Antennoi filiformes, ciliatae j scapo ovato, articulo 

 tertio caeteris paulo longioribus. Prosternum inter coxas arcuatum. Meso- 

 sternum 'oblongum, declive. Epimera mesothoracica obliquaa, cetabula hand 

 attingentia. Tihice intermediae extus emarginatae. Ungues divaricati. 



Closely allied to the Mediterranean genus Farmena, and very similar in 

 facies, except that the general form is shorter and more ovate. 



Somatidia antarctica. 



Parmena antarctica, White, Voy. Ereb. and Terr., Ins. p. 22. 



The elytra have distinct, almost toothed humeral angles ; but their outline 

 is very oblique from the angle to the true base j each elytron has two small 

 tufts of hair. Long. 2J — 3 lines. 



Port Nicholson j also Auckland {Mr. Lawson). 



Somatidia ptino'ideSy n. sp. 



S. cupreo-fusca, fulvo-griseo pubescens, setosa ; thorace ovato, crebre grosse 

 punctate ; elytris a medio usque ad basin fortiter angustatis humeris nullis, 

 macula utrinque exteriore basali, fascia mediana maculaque apicali suturali 

 nigi'is, penicillis nullis; antennis et pedibus rufescentibus. Long. \l — 2 J 

 lin. 



Auckland {Mr. Lawson) ; four examples. The fourth joint of the antennae 

 is veiy short. 



Stenellipsis, nov. gen. 



Corpus angustum, ellipticum, convexum, subtile tomentosum, laeve. Caput 

 exsertum, inter antennas modice late concavum, fronte quadrata. Palpi 

 Bubelongati, robusti, articulis ultimis fusiformibus. Thorax transversus, antice 

 et postice constrictus, medio convexo, lateribus tumidis, inermibus. Elytra 

 convexa, prope basin transversim depressa, apice obtuse rotundata, fere 

 truncata ; stria suturali solum impressa, versus basin abbreviata. A cetahula 

 antica et intermedia extus clausa. Prosternum inter coxas vix arcuatum, 

 angustissimura, ai)icc dilatatum ; mesosternum oblongum, vix declive.
