BLAIE, F.E.S. {Published by permission of the Trustees of the British Mnseuiu). Ill the Ann. and Mag. Nat. Hist. (6) XVII, pp. 230-231, Mr. C. 0. Waterliouse publislied a re-description of the type of " Tenehrio ferrnginens, Fab.," still preserved in the British Museum, drawing attention to the fact that it belongs to the family Cucujidx, and that the insect kno-wn in our collections as " Triholinm ferrugi-neum, F.," which had been wrongly identified, " will have to bear a different specific name." Mr. Champion followed (Eiit. Mo. Mag., 1896, p. 82) by disputing this eouclusiou. While admitting that the original description of Tenehrio ferrvgineus by Fabricius (Spec. Ins. I, 1781, p. 324) certainly did not refer to our insect, he contends that the Tenehrio ferruginens of the " Mantissa Insectorum," 1, 1787, p. 212, or the Trogoaiia ferrtiginea of the " Entomologia Systematica," 1, 1792, p. 116, may quite well refer to oiu-species, and says that in these works " no reference whatever is made to the original description in the Species Insectorum." He continues -. " It is perfectly evident that he (Fabricius) confused more than one species under the name ferrngi-nens, and till the contrary is proved the name ferrnginens (1787) can be retained for the Triholinm.'' Grebien, in Junk's " Coleopterorum Catalogus," 1911, accepts Champion's view, and cites the insect as T. ferrnginenm, F., Mant. Ins. I, 1787, p. 212. But this Tenehrio ferrnginens (1787) is an absolute homonym of Tenehrio ferrnginens (1781), and I'onsequeutly, even if difPering in meaning from its previous usage, is invalid. We have no evidence, liowever, that a different meaning is intended. Though Mr. Chanij)ion says that in the two later descriptions no reference whatever is made to the original description, this is hardlv correct. As recrards the " Mantissa," no reference is
