Section V.—ACIUDTODEA. 
To tliis section belongs tlie bulk of tlie collection, and includes a considerable 
number of large and moderate-sized species, besides a few small ones. Many of 
these have been previously collected, though scientitically they may be new or 
hitherto unrecognised. The literature of this section at my command is too 
incomplete to allow me to deal thoroughly with the collection. In addition to 
those described below, the collection includes specimens belonging to the family 
Tryxalidce (one species) and to the genera Pezotettix (one species), Brachytettix 
(two species), Caloptenus (two species), and to the group Eremoboides (seven 
species).
