Abstract
It is not with the intention of assisting the narrow specialist that this paper is written ; the purpose is to enable the observant student of nature and the economic entomologist to recognize those formsthat often come to their notice and thus obviate the frequent delays and discouragements in obtaining information through other channels.Keywords
