MODERN CLASSIFICATION OF INSECTS. 



in my monograph upon this family, I have endeavoured to show the 

 propriety of their removal to the Necrophagous stirps. In the ge- 

 nera Paussus, Hylotorus, and Platyrhopalus W., the antennas appear to 

 be only 2-jointed, the terminal joint being very large and irregular, 

 varying very considerably in its shape. In Pentaplatarthrus W. the 

 antennae are very large, the five terminal joints being very flat. In 

 Lebioderus TV., the same number of joints also apparently exists, each 

 joint of the club being posteriorly spined ; and in Cerapterus the an- 

 tennae are also very large, and 10-jointed. The genus Trochoideus W. 

 I have ascertained, by the dissection of a second species from Mada- 

 gascar, to belong to the Erotylida?. 



The sixth family Mycetophagid^ *, as a provisional group, may 

 be considered as comprising the residue of the family Engidse Stephens, 

 in which the species are rather fungivorous than subcortical ; the
