made to the Species lusectoriim, and a different origin is indicated by 

 " Habitat et Halee Saxouum Dom. Hybner." So far, tliougli in any case 

 a homonym, this Tenehrio ferrugineus may be intended to mean a 

 different insect from the Tenehrio ferrugineus of the Species Insectorum. 

 The description of Trogosita ferruginea, Ent. Syst. I, 1792, quite dis- 

 poses of this possibility, for here it is definitely synonymised with the 

 Tenehrio ferrugineus of the " Mantissa," and Fabricius continues : 

 " Habitat in Africa sequinodiali Mus. Dom. Banks, in Americse Insulis 

 Dr. Pflug," the words in italics being obviously quoted from the 

 Species Insectorum, 1 781 . It is perfectly clear, theref oi-e, that Fabricius 

 supposed that he was dealing with one and the same species in these 

 three instances. Furthermore, this conclusion is borne out by Sherboru's 

 "Index Animalium," which quotes Trogosita ferruginea (1792) as 

 synonymous with Tenehrio ferrugineus (1781), and in the " Epitome 

 Entomologise Fabricianse," by Bergstrasser, p. 18, where Trogosita 

 ferruginea is the only one that appears. From these facts then, it is 

 evident that the na,m.e ferrugineum, F., as applied to the Tribolium, can 

 have no locus standi whatever. 



That Dermestes navalis, Fab., Syst. Ent., 1775, p. 56, cannot refer 

 to this insect, has been sufiiciently demonstrated by Champion, loc. cit., 

 yet the name navale, Herbst, Kaf. IV, 1792, still appears in Junk's 

 Catalogue as a synonym of " ferrugineum, F., 1787," though this 

 reference is nothing more than a quotation, and translation, of the 

 description of Fabricius. 



In Kaf. VII, 1797, p. 282, t. 112, f. 13, however, Herbst gives a 

 description of our insect, together with a sufficiently recognisable 

 figure, as Golydium castaneum; the name castaneum, Herbst, there- 

 fore remains in possession of the field as the specific name of this 

 Triholium. 



It may be noted that the genus Tribolium (1825) was made by 

 Macleay for the reception of Golydium castaneum, Herbst, and though 

 Trogosita ferruginea. Fab. (Syst. Eleuth. 1, 1801), is cited amongst its 

 synonyms, this is merely a reference to Trogosita ferruginea (Ent. 

 Syst., 1792), and Macleay was evidently doubtful of the correctness of 

 the synonymy. 



Neither Mr. Waterhouse nor Mr. Champion seems willing to 

 assign to any genus the true ferrugineus, ¥., but rather than let it 

 continue longer without any generic appellation I propose for it the 

 name Triholioides, which may be characterised as follows : —
