110 MR. HALDEMAN'S DESCRIPTIONS OF COLEOPTERA. 



To these may be added nossidium Er. and sph^rius Waltl Motchulsky has 

 stated a point overlooked by Gillmeister, namely, that Gyllenhal placed T. atomaria 

 and fascicularis in the genus Ptilium, and he accordingly applies the latter term to 

 the first group, without inquiring how far it may be synonymous with Kirby's name, 

 which he applies to the fifth and part of the third group ; another portion of the third 

 with the fifth, forming his genus Ptinella. Allibert, Rev. Zool. 1847, p. 189, says 

 that Ptinella " est un nom impropre qui signifie petit Ptinus et non petit Ptilium ;" 

 an objection which is untenable, the names in question being as distinct as Callidium 

 and Callidema ; nor is it certain that Ptinella was intended as a diminutive of 

 Ptilium.
