black, paler at the sides ; it is broadJy but slightly sinuate 

 at the base on each side, the extreme hind angle just a 

 little rounded. The elytra are the width of the thorax at 

 the l)ase, almost straight at the side, a little narrowed 

 behind, the hind angle much rounded ; they are sparingly 

 and extremely finely punctured. The hind body is pitchy, 

 Avith the last segment and the hind margins of those before 

 it paler; its punctuation fine, closer and more distinct 

 than that of the elytra. The legs dark yellowish. 



In the female the dorsal plate of the 7th segment of the 

 hind body terminates in four veiy long, equidistant, slender 

 spines, of which the two middle ones are slightly more 

 slender than the lateral ones ; the ventral plate of the same 

 segment also ends in four slender spines, of which the two 

 in the middle are rather longer, but not stouter than the 

 lateral ones. 



Ega ; two female specimens. 



4. Coproporus retrusns, n. sp. Piceus, convexus, 

 nitidus, antennis apicem versus incrassatis, pedibusque 

 rufis ; capite prothoraceque la3vissimis, elytris pai'ce sub- 

 tilissime punctulatis, lateribus subparallelis, angulo externo 

 minus fortiter rotundato. Long. corp. 2| lin. 



This species is very closely allied to the thi-ee preceding 

 ones, and is about the same size, but has the antennte 

 stouter and more thickened towards the extremity, and 

 its elytra are straighter at the sides. Antennae moderately 

 long, rather stout, distinctly thickened towards the ex- 

 tremitv, of an obscure reddish colour in the middle, with 

 the three basal and the lltli joints paler; 3rd joint longer 

 than the 2nd ; 4th to 10th each a little shorter and 

 broader than its predecessor, the 10th scarcely so long as 

 it is broad ; 11th joint stout, one and a half times as 

 long as the 10th. Thorax as broad as the elytra, much 

 narrowed to the front ; a little sinuate at the base on each 

 side, so that the hinder angles project a little backwards, 

 the extremity of these rounded. Elytra rather straight 

 at the sides, with the external angle moderately rounded, 

 Avitliout any lateral impri'ssit)n ; very finely and sparingly 

 punctured. Legs dark yellowish. 



Ill the female the ventral plate of the 7th segment of 

 the hind bodv ends in four spines, of which the two 

 middle ones are very elongate; the lateral ones are a good 

 deal shorter than the middle ones, and but little stouter;
