sides with irregularly disposed tubercle-like teeth; the region 

 of the posterior angle is somewhat swollen, the angle itself 

 produced (slightly backwards) into an acute process ; the base 

 very slightly sinuous (nearly straight) in its middle portion, 

 but rather strongly sinuate behind each posterior angle. The 

 elytra are parallel, very slightly narrowed at their apex, 

 convex at the base, depressed posteriorly ; very strongly, 

 closely, and rugosely punctured at the base ; the rest of the 

 surface, although strongly and closely punctured, is not so 

 strongly sculptured as the base ; each elytron has an obtuse 

 ridge near the suture, rising before the middle of the elytron 

 and terminating before the apex ; there is a somewhat more 

 marked jfeld near the margin, rising near the shoulder and 

 extending nearly to the apex ; the space between these ridges 

 is nearly flat (with an indication of a third short ridge in the 

 middle) ; the side beyond the lateral ridge is suddenly deflexed ; 

 the sutural angle is slightly dentiform. The legs are long ; 

 the anterior femora and tibia? very rough and closely beset 

 with small shining tubercles, which on the edges of the tibiae 

 form small teeth ; the underside of the femora is transversely 

 rugulose ; the other legs are not so rough, and the base of the 

 femora is nearly smooth. The fifth segment of the abdomen 

 is very slightly sinuate in the middle.

Lepturinae. 



Artelida asperata, n. sp. 



Nigra, subtilissirae griseo-pubescens ; oculis fortiter granulatis ; 

 thorace medio rugoso, quadrituberoso, lateribus dente conico 

 armatis ; elytris dorsaliter paulo impressis, regione basali granu- 

 loso-punctatis ; antennis, tibiis tarsisque piceis. 



Long. 6-8^ lin. 



Rostrum very short. Eyes prominent and strongly gra- 

 nular, moderately separated below and above. Thorax mode- 

 rately transverse, constricted in front, rather thickly and 

 rugosely punctured, with four distinct tumours on the disk ; 

 the lateral tubercle prominent, conical. Elytra not much 

 narrowed posteriorly, finely coriaceous, with the basal region 

 moderately thickly punctured with horseshoe punctures, the 

 apex of each elytron obtuse ; there is a slight costa-like fold 

 running obliquely from the shoulder, not extending to the 

 apex. The claw-joint of the male is much dilated at the 

 apex.
