elongati, articulis terminalibus vix dilatatis oblique truncatis. Antennce basi 

 distantes, haud ciliatse ; scapo et articulis tertio et quarto requalibus, brevibus 

 quinto usque undecimum paulo longioribus. Thorax rhomboideus, tavis. 

 Elytra linearia, utrinque postice leviter attenuata, apice acute truncata, supra 

 fere lsevia. Prosternum inter coxas angustum j mesosternum oblongum ; 

 metasterni episterna fere parallela, apicem versus tantum angustata ; acetabula 

 antica et intermedia extus paulo aperta. Abdomen (P.) lineare, elongatum ; 

 segmentis primo usque quartum normalibns, quinto ventrali late excavato et 

 dense atque longe piloso ; pygidio valde convexo et arcuato. Pedes robusti ; 

 femora gradatim incrassata ; tarsi breves, posticorum articulo primo vix 

 secundo tertioque conjunctim longiore. 



Another anomalous genus, having no near affinity with any other known 

 form; it seems, however, to come nearest such genera as Callimus, and 



Australian 



differs 



the same sex in Earinis in the concentration of the hairiness of the abdomen 

 on the fifth ventral segment and on the arched borders of the pygidium. The 

 form of the metathoracic episterna is very similar to that of Earinis, as is also 

 the thorax— oblong, with an angular dilatation in the middle of each side. The 

 head and thorax together are small relatively to the rest of the body. The 

 antennae (F.) are not much more than three-fourths the length of the body.

The head is sparingly but strongly punctured, except the middle of the 

 crown, which is convex and glossy. The thorax is small, very faintly 

 punctured, and with a tranverse depression near the anterior and posterior 

 margins. Each elytron tapers gradually from base to apex, the latter being 

 broadly and sharply truncated, and not reaching the tip of the abdomen ; the 

 surface is glossy, and bears only a few punctures, strongest near the base.
