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 SfC. tab. 11. 209. no. 4. with the following ^' Nota : 

 Get insecte, que nous n'avons pas ete k meme d'examiner, doit 

 sans doute former un autre genre, c'est aussi le sentiment de 

 Fabricius." Schonherr, however, in his Syn. Ins. 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 antennae, 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 anei et specierum affinum. Pausi jlavicornis foemina 

 nobis haud est visa, quare de ejus antennarum structura sumus 

 inscii, sed insectum ad ulteriorem indagationem in musaeo 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 Mely rides in the Families Natu- 

 relles : *' Le Pausus flavicornis de Fabricius parait devoir en 

 former un nouveau genre prtis des precedens." — 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
