586 COLEOPTERA 



Another anomalous genus, having no near affinity with any other 

 known form ; it seems, however, to come nearest such genera as Calli- 

 mus, and especially the Australian Earinis. I know only the female, 

 which differs from 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 transverse 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.

Nov. gen. 



Antenna not longer than the body, sparingly pilose ; the scape of 

 moderate length, incrassated but not clavate ; second joint minute ; 

 third not perceptibly shorter than the fourth ; joints three to nine sub- 

 equal ; nine to eleven shortest, except the second. The eyes are moder- 

 ately facetted considering their size, they are coarsely rather than finely 

 granulated ; they are of a sub-lunate form, the more bulky portion being 

 in front, whilst the central part, before its junction with that behind the 

 antenna, is a mere narrow band. The palpi have sub-ovate terminal 

 joints. The head is nearly as wide as the apex of the thorax, rather 

 abruptly deflexed anteriorly, with an impressed dorsal line and short 

 muzzle. The thorax is about as long as broad, moderately convex, with 

 an acute lateral tubercle behind the middle, and two small obtuse eleva- 

 tions on the disc in front ; the sides are rounded, and it is a little con- 

 stricted near the base and apex. Scutellum sub-oblong. Elytra oblong, 

 scarcely convex, slightly compressed, and rounded laterally ; the shoul- 

 ders are prominent, from thence they are gradually attenuated towards 

 the apices, which are, individually, acutely rounded, so that the apex 

 (entire) has the appearance of being triangularly excised at the suture. 

 The legs are of moderate length, the femora incrassated, the intermediate 

 and posterior tibise flexuose. 



The characters of this genus are totally distinct from those assigned 

 to Eburida by White, but as the species on which he founded the name 

 belongs to Didymocantha (D. sublineata), I have adopted his name for
