After all, the geographical range of our fauna, as regards the distribution of insects, is but incompletely marked, and the fact that artifical lines cannot limit the habitat of a species is every day made more apparent. The Florida coast is constantly turning up species properly belonging to the fauna of the West Indies, and Texas and Arizona are as often adding Mexican forms to our list. It is, nevertheless, somewhat strange that three such conspicuous species as those hereafter noted should have only recently appeared within our limits, or at least for so long a time have escaped the watchful eyes of our numerous observers.
