482 Longicornia Malay ana. 



Tmesisternus immitis. 



T. angustatus, fuscus, pube sordide grisea tectus ; 

 prothorace omnino pubescente, basi baud dilatata ; 

 elytris sub-cuneiformibus, macula centro-basali gla- 

 bra^ nitida. 

 Eab. — Mjsol. 



Closely resembling T. agriloiJes, but the elytra are 

 more rounded towards the apex, and not so broad at the 

 base ; the prothorax shorter, the disk altogether pubes- 

 cent, the sides only slightly broader posteriorly. 



Sphingnotus. 



Sphingnotus, Perroud, Ann. Soc. Linn. Lyon, ii. 410. 



Capwi^ magnum, exsertum, porrectum, antice valde trans- 

 versum. Oculi profunde emarginati. AntenncB cor- 

 pore breviores, setaceae, basi valde distantes ; scapo 

 obconico, articulis tertio et quarto gequalibus, caeteris 

 brevioribus. Prothorax brevis, transversus, lateraliter 

 marginatus et bilobatus, infra marginem spinosus, 

 apice truncatus, basi bisinuatus, lobo mediano trun- 

 cate. Elytra postice sensim angustiora, basi lobata. 

 Femora compressa ; tihi(£ valida; ; tarsi dilatati, 

 antici breviores, postici articulo basali brevi, trian- 

 gulari. Pro- et meso-stcrna ut in Tmesisterno. Abdo- 

 men segmento ultimo apice inermi. 



In M. Perroud's lengthened description and remarks 

 on this genus, he has not said a word as to the reasons 

 which induced him to separate it from Tmesisternus ; but 

 we infer from his italics that he was guided by the 

 " entirely divided " eyes, the form of the prothorax, the 

 lobed bases of the elytra, &c., and the non-clavate femora. 

 The first character is not exactly correct, a connection 

 between the two lobes really exists, and although the line 

 of union is very narrow, it is very distinct ; the other 

 characters are good. The type, S. mirahilis, is sometimes 

 divided in collections into two or more species ; it would 

 not be difficult to find characters for half-a-dozen, but cha- 

 racters do not make species, and I cannot satisfy myself 

 that there is more than one. M. Perroud has, however, 

 described two, which seem to be, and no doubt are, very 

 distinct; and as the work in which they appear is not 

 always at hand, I have given here the most essential of
