Ovata ; sat brevis ; rubro-ferruginea, vix iridescens, capite

 setoso ; capite confertim riigulose confluenter nee crasse,

 elytris (his geminato-striatis) obscure, punctulatis ; antennis

 manifeste longiori. 



Maris (exempli typici) antennis carentibus ; pygidio apice late 

 sinuato-ti'uncato. 



Feminse antennarum clava 5-articulata, hujus articulo 2° quam 

 3° (et basali quam ille) quarta parte breviori ; pygidio valde 

 gibboso apice minus late truncato. [Long. 11-|-, lat. 6 lines. 



Very near the S. Australian C. fortis, Blackl)., from which it 

 diflPers by its darker colour, somewhat broader and more robust 

 build, less distinctly punctured elytra, and the antennal characters. 

 In the female the basal joint of the club is not much more than 

 half as long as the third joint, and the second joint is about 

 intermediate in length between the first and third, whereas in C. 

 fortis (female) the basal joint of the club is scarcely shorter than 

 the second, and the second is scarcely shorter than the third. 

 The pygidiura also in C. campestris (female) is very much more 

 gibbous than in C. fortis. In the male the pygidium is much 

 more widely and less straightly truncate at the apex than in the 

 male of G. foTtis, and no doubt the antennal characters are 

 different. From C. giganteo,, Burm., the five-jointed (in the 

 female and no doubt in the male also) flabellum of the antennae 

 distinguishes the present insect. In C. dubia, Blackb., the 

 antenaiB (female) are much like those of C. campestris, — the 2nd 

 joint of the flabellum, however, being markedly less abbreviated, — 

 but the species inter alia is considerably more strongly punctulate, 

 more nitid and more elongate. The other species of this group of 

 Colpochila (large insects having a sharply defined lateral protho- 

 racic gutter set with long soft hairs) difi'er still more widely. In
