Tonkin: Hoabinh (August). 



A series of specimens was found by M. Vitalis. 



This is an addition to the very insufficiently known group 

 of forms allied to the genus Clemmus, in which the tarsi are 

 filiform and consist of only three joints, apparently through 

 tlie complete fusion of the 1st and 2nd. Pararhymbus 

 differs from the latter genus by the less prominent and less 

 coarsely granulated eyes, the very slender 11-jointed antennae, 

 of which all the joints except the penultimate one are 

 elongate, the absence of lateral prothoracic ridges due to the 

 production of the basal fovese in Clemmus to the front margin, 

 and the more broadly dilated elytra, with produced apical 

 angles. 



The upper surface is clothed with a fine and not very close 

 greyish pubescence, which is almost absent from the middle 

 of the prothorax and the region of the scutellum. The 

 elytra are everywhere strongly and regularly ])unctured. 



It is very deep brown in colour, with the lower surface, 

 the front of the head, the legs, and anteunoe red, but the last
