100a. Mandible symmetrical. Fig. 299 Family COLYDIIDAE 



Some species are known to feed 

 upon decaying vegetable matter, 

 a number of them are predacious 

 upon larvae or pupae of several

 Fig. 300 Family MYCETOPHAGIDAE 



The members of this fam- 

 ily chiefly live in rotting 

 wood or under bark, asso- 

 ciated with fungi. The lar- 

 vae of Berginus maindroni 

 Grouv. are reported to feed 

 upon lac and the lac insects 

 in India.

102a. Cerci present 103 



102b. Cerci absent Subfamily Oedemerinae, OEDEMERIDAE 



Most of the members of this interesting family fall here. They are 

 small to medium size. The known larvae live largely in decaying
