In those species that attack dead tissue only, some 

 of which, like the cigarette beetle and death watch, 

 are treated in Chapter X, we get an approach to the 

 scavenger type; and yet the term scavenger seems 

 scarcely a fitting one since the material attacked is 

 not in a condition of either ferment or active decay. 



In the "soldier beetles" and "fireflies," which by

we have a wide departure from the general feeding 

 habit, most of them being predatory in the larval 

 stage, and feeders among flowers, where they feed at

The series Lamellicornia, containing species with 

 the feet 5 -jointed and the antennae terminated by a 

 leaf -like club, includes vegetable feeders almost ex- 

 clusively, in both larval and adult stages, and, in gen- 

 eral, the feeding is upon live vegetation. There are
