a Family of Coleopterous Insects. 677 
It only remains for me to add a few observations upon the 
only remaining insect which has been introduced into the family, 
but which does not appear referable thereto. 
Fabricius, in his Systema Eleutheratorum, comprised in the 
genus Paussus an insect under the name of P. flavicornis, with 
the remark, ‘‘ Animalculum singulare vix hujus generis." La- 
treille is the next author who mentions this insect, in his Histoire 
Naturelle &c. tab. 11. 209. no. 4. with the following ** Nota: 
Cet insecte, que nous n'avons pas été à méme d'examiner, doit 
sans doute former un autre genre, c'est aussi le sentiment de 
Fabricius." Schönherr, however, in his Syn. Inis. vol. i. p. 3. 
no. 9, notwithstanding these observations of Fabricius and La- 
treille, and evidently overlooking the specific description of the 
terminal joints of the antennz, has placed it amongst the species 
of Paussus without any expression of doubt. Dalman, in the notes 
inserted at the end of his Analecta Entomologica, agrees with 
Fabricius and Latreille, observing ** De Pauso flavicorni Fabr.: 
Hoc insectum minime Pausi est generis, tarsi enim omnes eviden- 
ter 5-articulati, elytris molliusculis, toto habitu atque colore ad 
Malachios nimis accedere videtur, et ipsa antennarum singularis 
forma sat bene congruit cum earundem structura in masculis 
Malachii enei et specierum affinum. Pausi flavicornis foemina 
nobis haud est visa, quare de ejus antennarum structura sumus 
inscii, sed insectum ad ulteriorem indagationem in muszo nos- 
tro, sub nomine Malachii flavicornis, militat."—pp. 103, 104. 
Latreille, profiting by these observations, adds the following 
note at the foot of his family Melyrides in the Familles Natu- 
relles: ** Le Pausus flavicornis de Fabricius parait devoir en 
former un nouveau genre près des précedens."—p. 353. 
The preceding remarks, added to an examination of a conge- 
nerous insect in Mr. Haworth's cabinet, under the manuscript 
name of Cerocoma marginata, subsequently mentioned, have
