XXX. — Notes on Longicorn Coleoptera of the Group Ceram- 
bycinae, with Descriptions of new Genera and Species . By 
Charles J. Gahan, M.A., Assistant in the Zoological 
Department, British Museum. 
The extreme difficulty which the systematic treatment of the 
group Cerambycinse (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 purpose consulted most of the types. To M. Rend 
Oberthur, of Rennes, I must in particular acknowledge my 
thanks, 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 — Cleonice 
vestita — is quite foreign to the group. It has been redescribed 
and figured by Mr. Pascoe under the name Seuthes sericatus , 
and undoubtedly belongs to the group Glaucytinge, in which 
Mr. Pascoe placed it. 
Taurotagus, Lacord. 
Taurotagus subauratus , sp. n. 
Antennis ( c? ) corpore plus sesqui-longioribus ; capite supra sulco 
medio elongato impresso ; prothorace apice valde constricto, 
lateraliter et supra obtuse tuberculato et valde rugoso ; elytris 
pube brunneo-aurata holosericea dense obtectis, apicibus angustim 
truncatis vel subrotundatis, et ad suturam breviter mucronatis. 
Long. 44, lat. 1 2\ mm. 
Hab. Abyssinia (J. C . Bowring , Esqi). 
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 moir£ reflexions. The head carries 
above a median longitudinal groove, commencing between 
the eyes and extending back to the occiput. The antennee 
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 
18*
