4 GO Mr. C. J. Galian on new Longicorn Coleoptera. 



M. Fairmaire has recently published a short diagnosis of a 

 species of this genus (T. rufullpennis^ Coniptes Rend. Ann. 

 8oc. Ent. de Belgique, 1880) whicli is apparently much more 

 nearly allied to pectinicornis than is the species above 

 described. 



Imerinus, gen. nov. 



Female. — Head with the front transverse, scarcely concave 

 above, divided longitudinally by a fine median groove, and 

 separated from the epistome by a deep, transverse, slightly 

 arcuate impression. Last joint of palpi subfusiform. Eyes 

 coarsely faceted. Antennaj barely surpassing the elytra ; 

 first, third, and fourth joints subequal, each shorter than the 

 fifth, the sixth and succeeding joints decreasing in length. 

 Prothorax strongly constricted near base and apex, tubercled 

 at the middle of each side, and with four or five tubei'cles on 

 the disk. Anterior margin of pronotum slightly produced 

 and rounded ; posterior margin rounded in the middle and 

 sinuate towards each side. Elytra each rounded at the apex 

 and terminating in a short sharp spine. Legs increasing in 

 length from the anterior to the posterior. Femora thickened 

 below the middle. First joint of tlie posterior tarsus longer 

 than the two succeeding joints combined. Prosternal process 

 moderately broad, subcanaliculate along the middle, bilobately 

 dilated posteriorly. The anterior cotyloid cavities closed in 

 behind, strongly angnlate externally. Litermediate cotyloid 

 cavities widely open on the outside. Abdomen with the first 

 ventral segment very long, the second much shorter, trun- 

 cate, and thickly fringed with long hairs behind ; the 

 remaining ventral segments almost entirely concealed. 



Of somewhat doubtful atlinities, the genus will, I think, be 

 best placed near the riilyctenodides. 



Imerinus granidlfcrus J sp. n. 



Brunneo-ferrni^ineus, griseo subtilitor pubescens ; prothorace dorso 

 utriiujuc bituberculato, tuborciilo antico bifido obtuso, tuberculo

Head and prothorax impunctatc, the latter with an acute 

 tubercle on the niidiUe of each side and a strong transverse 

 callosity close to tlie antero-lateral margin ; with four tubercles 

 above, of which the two ajitorior arc obtuse and each some-
