Abstract
The Colony of Southern Nigeria was traversed by the writer in 1910, and the following short report is founded on observations made during the first seven months of that year. As will be seen later on, various officers, chiefly medical, stationed in the Colony, afforded material help in the investigation, and the results of their work are also incorporated here; the collections of injurious insects made by them have been duly acknowledged in previous issues of this Bulletin, and also, as far as possible, throughout this report.
