INTRODUCTORY NOTE 
T he majority of the specimens recorded in the present paper are from 
the Patani States, but some are from Perak and a few, for which Mr. 
Robinson is solely responsible, from Selangor. Mr. Distant remarks 
that a peculiarity of the collection is the poor representation of conspicuous 
forms. This is due to no scheme of the collectors, for we took all that we saw 
or that fell into our sweep-nets ; but it may be due, at any rate in part, to the 
fact that the nine months we spent in the Patani States were very dry and to 
the subsequent disappearance of the larger species, as the ‘ Skeat ’ collection, 
which was obtained in the same district in a very much wetter year, is 
particularly rich in conspicuous forms. 
Another point of interest, not fully brought out in the paper, is the 
number of Hcteroptera which resemble ants in appearance and movements. 
Unfortunately, the majority of such forms are immature, and Mr. Distant 
prefers not to express an opinion as to their identity ; some of them will be 
mentioned again in the notes added to Colonel Bingham’s Report on the 
Aculeate Hymenoptera, which is unavoidably postponed for the present. 
Mr. Robinson is mainly responsible for the editing of the report on the 
Heteroptera, but his departure for Malaya, to take up the curatorship of the 
State Museum at Kuala Lumpur, has obliged me to write this note.
