54 MR. G. A. K. MARSHALL OX COLEOPTERA [Jan. 19, 



rather elongate, slender, scape nearly reaching eye ; the two basal 

 joints of funicle subequal. Prothorax a little longer than the 

 width at base, apex narrowei", sides slightly ampliated and armed 

 with a sharp spine about middle, dorsal anterior margin slightly 

 ■convex, ocular lobes well developed. Upper surface slightly con- 

 vex, with a shallow transverse impression near apex, modei-ately 

 closely set with large rounded tubei'cles, leaving a shallow central 

 furrow containing a short carina ; tubercles bare, with depressed 

 pale sette, the interstices with thin brownish scaling. Elytra 

 oblongo- ovate, much nari'ower in c? , shouldei's sloping, sides 

 scarcely rounded, broadest about middle, apical processes short and 

 bluntly conical in $ , rather longer and sharper in S • Upper 

 surface convex, with rows of distinct granules instead of punctui-es ; 

 interval 1 granulate ; 2 with a short subcristate row of tubercles 

 on the declivity and with small depressed tubercles continuing 

 interruptedly to base, though occasionally altogether absent ; 

 intervals 3, 5, and 7 with complete rows of small, closely set, sub- 

 conical tubercles ; 4 and 6 entirely devoid of tubercles or with 

 a few isolated ones ; tubercles bare, with depressed pale setfe, the 

 interspaces with thin brownish-grey scaling and two paler patches 

 at the top of the declivity. Legs rather long, with sparse pale 

 scaling and a denser ring near apex of femora ; posterior tarsi 

 with the 3rd joint slightly broader than the other two, 2nd and 

 3rd subequal in length, 1st longer.

Dr. Kolbe and Mons. Fairmau-e compare this species respectively 

 with spectrum Gyl. and tuherculatus Boh. MS. {:=severus Gyl.), 

 but it is still more closely allied to ficrvus Fahr., of which I at 

 first regarded it as a variety. HoAvever, the absence of the in- 

 ferior basal furrow of the I'ostrum is a good character by which 

 the species can be at once recognised, for this fuiTow is quite 

 distinct in all the three species mentioned above. H. tenuegranosus 

 differs further from IT. furvus in its longer and more strongly 

 curved rostrum, its longer and more slender antenna?, and finally 

 the much smaller size of the pi-othorax in proportion to the elytra, 

 which is specially noticeable in the $ . This species has a wider 

 range than any other in the genus.
