Tetbalophus, a new genus of the Etimidee, which appears to approach most 

 nearly to the genus Mythites of Schonherr, but, judging from the description, must 

 have the antenna? shorter, and differs, moreover, in having two longitudinal crests on 

 the rostrum, the sides of the thorax much produced and angular, and the upper sur- 

 face with two high crests ; the legs very slender. 



T. sculpturatus is 5f lines long; black, and has two series of angular tubercles on 

 each elytron, the hindermost tubercle being the largest in the inner series, and the 

 foremost and last tubercles of the outer series are both very large. Hab. Swan River. 



Leptostethus, a new genus of Pachyrhynchida, near Polyphrades in its charac- 

 ters, but with the body much more elongated, and the anterior coxae separated, 

 leaving a narrow chest between them. 



L. marginatus, a large insect, being 7| lines long,* and 2f wide ; much elongated, 

 the rostrum very broad and flat above, the sides of the body nearly parallel : black ; 

 thorax thickly covered with small glossy granules ; elytra crenato-striated : both thorax 

 and elytra with a broad, yellow, squamose band at the sides ; femora red, with the 

 apex black. 



L. Waltoni is black, covered with pale, dirty yellowish scales ; has the femora red, 

 the rostrum with four keels ; thorax thickly granulated ; elytra punctato-striate, the 

 apex somewhat produced at the suture; length 5 lines; breadth 2 lines. Both spe- 

 cies are from South-West Africa. 



Achlainomus, new genus of the Pachyrhync hides. General form most near to 

 Prostomus, the rostrum wants the longitudinal ridges seen in that genus ; the jaws 

 are short, the joints of the antenna? rather shorter, the thorax less convex ; the elytra 

 shorter and less convex, separated from the prothorax, and with the humeral angles 

 not produced : fore tibia? much curved and very strongly dentated within ; middle 

 and hind tibia? dilated and produced externally and internally at the apex. 



A. ebeninus is from India: glossy black, destitute of scales; antenna?, and termi- 

 nal joint of tarsi pitchy red ; rostrum canaliculated ; thorax very delicately punctured, 

 canaliculated ; elytra punctato-striated. Its length is 4^ lines ; width If line. 



Enaptorhinus, a new genus of the Brachyderida, nearly related to Geotragus, but 

 differs in the form being much more elongated, the rostrum somewhat convex above, 

 separated from the head by a transverse depression, the antenna? stouter and with 

 shorter joints. The male has the hinder tibia? clothed with very long pale hairs. 



A. Sinensis is 4f lines long, and l£ line broad, of a pitchy brown colour, sparingly 

 clothed with scales; thorax rugose, and with three pale lines : elytra punctato-striate; 

 the back much depressed, and even slightly concave in the middle, but somewhat 

 humped near the apex, where there are numerous long hairs. Hab. N. China. 



Cubicosomus, a new genus of the Cleonidce, near Leptops, but with the elytra 

 very short and nearly of a cubical form ; the two basal joints of the funiculus only are 

 obconic, the rest very short ; the rostrum rather longer than in Leptops. 



The rostrum is not included in the dimensions of length given in the paper.
