Prionus tet aniens. 



P. fuscus, prothorace scutelloque nitidis, interrupte et subtiliter 

 punctatis ; elytris rugosis, fere obsolete quadricostatis. 



Hab. Chosan (Japanese Sea). 



Dark brown ; bead not very closely punctured : protborax 

 sinning, two rather strong teeth on each side, the posterior 

 angle well-marked, but not spiniform; punctures very fine, 

 interrupted in the middle; scutellum smooth and shining, 

 marked by a few small punctures : elytra somewhat narrow, 

 finely rugose, very closely covered with very numerous small 

 punctiform impressions separated from each other by minute 

 zigzag lines, very clear and distinct under a good lens, each 

 elytron marked by two scarcely elevated but sufficiently obvious 

 lines : body beneath and femora glossy brown : legs rather long, 

 robust ; tibiae spinosely rugose, especially the two posterior pair, 

 fluted; tarsi reddish chestnut : antennae 12-jointed, the joints 

 large, mostly depressed and dilated on both sides from the third 

 to the ninth or tenth, but gradually less on one side as they 

 approach the twelfth, which is oblong-ovate. Length 14< lines. 



Allied to P. BesicanuSj but, among many other points of dif- 

 ference, distinguished by the numerous small spines covering 

 the intermediate and posterior tibiae. I owe my specimen to 

 Arthur Adams, Esq., R.N. 



Hoplideres lavicollis. 



( $ ) iy. brunneus, subnitidus ; prothorace bicalloso, obsolete punc- 

 tate ; elytris antenuisque muticis. 



Hab, Madagascar. 



Reddish brown, subnitid ; face with crowded but very shallow 

 punctures : protborax with five spines on each side, the two 

 posterior united at the base ; the disk with two large flat callo- 

 sities, from each of which projects a short lateral tooth, the 

 interval obsoletely punctured ; scutellum nearly semicircular, 

 minutely punctured : elytra very glossy and thickly punctured 

 at the base, suddenly becoming very finely and then almost ob- 

 soletely punctured, and at the same time losing much of the 

 glossiness, not spined at the shoulders, and the sides beneath 

 not serrated : body beneath with a short_, greyish pile ; antennae 

 without spines. Length 14 lines. 



Much shorter and more glossy than H, spinipennis ; the head 

 and protborax not coarsely and roughly punctured; the shoul- 

 ders and sides of the elytra beneath without armature, the 

 punctures at their bases equally disposed from side to side, and 

 no spines on the antennal joints. On account of the last cha- 

 racter, it comes rather badly into Hoplideres, in a technical 

 point of view.
