XXX. — Notes on Lnn'jlrorn Coleoptera of the Group Ceram- 

 byciiuB, ivith Descriptions of new Genera and Species. By 

 Chaulks J. Gauan, M.A., Assistant in the Zoological 

 Departnieut, British ^Iiiseuin. 



The extreme difficulty which the systematic treatment of the 

 group Cerambycina3 (Cerambycides vrais, Lacord.) presents 

 has been recognized by every entomologist who has attempted 

 it. Our collections are, I think, still in too incomplete a state 

 to enable this difficulty to be overcome. Without attempting 

 to give a complete revision of the group, I have in the fol- 

 lowing paper made such notes upon genera and species as will, 

 I hope, help the student in his determinations. I have 

 corrected the synonymy of a good many species, having for 

 this jjurpose consulted most of the types. To M. liend 

 Oberthur, of Kennes, I must in particular acknowledge my 

 tiianks, for having so kindly forwarded to me the types of 

 those of Thomson's species which, from their descriptions, I 

 was unable satisfactorily to make out. One of these — Gleonice 

 vestita — is quite foreign to the group. It has been redescribed 

 and figured by Mr. Pascoe under the name Seuthes sericatusj 

 and undoubtedly belongs to the group Glaucytina3, in which 

 Mr. Pascoe placed it. 



TaueotaguS, Lacord. 

 Taurotagus subauratuSj sp. n. 



Antennis {S) corpore plus sesqui-longioribus ; capite supra sulco 

 medio elongato impresso ; prothoracc apice valde constricto, 

 lateraliter et supra obtuse tuberculato et valde rugoso ; elytris 

 pube brunneo-aurata holoscricea dense obtectis, apicibus angustim 

 truncatis vel subrotundatis, et ad suturam breviter mucronatis.

Hah. Abyssinia (J. C. Bo7cring, Esq.). 



The unique specimen of this species was in a rather greasy 

 condition ; but after soaking in benzole it is seen to have, at 

 least on the elytra, a beautiful golden-brown and rather dense 

 pubescence, giving slight moire reflexions. The head carries 

 above a median longitudinal groove, commencing between 

 the eyes and extending back to the occiput. The antennge 

 are more than half as long again as the body, with the scape 

 strongly rugose-punctate, and at the same time very minutely 

 and closely punctulate ; the third joint is much longer than
