[The almost complete absence of the members of apo- 

 sematic Coleopterous groups is very marked. In fact, the 

 whole of the nuuierous beetles are probably cryptic, with 

 the following exceptions. The species of the Eumolpid 

 genus Syagrns is probably distasteful; for it freely exposes 

 itself on leaves, where its shining black appearance renders 

 it conspicuous. It is worthy of note that the only bird in 

 which it was found, Marronyx capcnsis, also ate Reduviid 

 bugs. The Phytophagous Macroeoma aurcovillosa belongs 

 to a probably distasteful group, but it is itself green in 

 colour ; it was only eaten by one species. The Hispid 

 Platypria is probably distasteful, and here too the only 

 species of bird which ate it, Trrisor erythrorrhynchus, also ate 

 the conspicuous Gassida {Asindomorpha) ininctata and 

 Pentatomid bugs. The above-named Cassid was also found 

 in two other species of bird. The most remarkable exception 

 is however the typically-coloured Can th arid, Mylahris 

 octilata, only detected in Meroi^s natahnsis. Here we 

 find the interesting proof that under certain circumstances, 

 and with certain enemies, the most marked distasteful
