EXPLANATION OF PLATES. 



Plate V. —Mound nest of Termes redemanni, with a solid 

 apex, and a single "chimney'* on the right. The nest was 

 built round a branch of a rose bush : this emerges just below 

 the chimney. The branch was not attacked by the termites, 

 and bore healthy shoots and leaves. Herbaceous plants are 

 growing on the nest. 



Plate VI. — Section of the same nest. The apex (above the 

 chimney) is solid, the apparent hollows being caused by the 

 tool used in cutting the section. The chimney shaft runs 

 down on the right, and the orifices of the small lateral galleries 

 may be seen on its wall. The subterranean portion and the 

 royal cell are not shown. 



Plate VII. — Three combs from a nest of Termes redemanni: 

 the upper layers are newly built, and have no " spheres " on 

 the outside : the latter are seen at the edges of the galleries, x \ 



Plate VIII. — Two combs from a nest of Termes obscuriceps : 

 the lower one bears numerous aborted agarics of the Plvti us 

 form. The open galleries on the top distinguish this comb 

 from that of Plate VII. x !,. 



PlaU IX. — Developing agarirs {Armillaria form) on the 

 comb of an underground nest of '/'< riucs rxhniunrii in situ. The 

 stalks of the five which have appeared above ground are at 

 the back of the cavity, x ] 



Piatt X. -Developing agarics (ArmiUaria form) <>n a oomb 

 of Termes redemanni. x \. 



Plat> A'/. —Mature agaric. The I'luteus form with a thin 

 cartilaginous covering on the pileus ; developed in moderately
