During the last decade, however, as specialists have taken up the work of monographing the more neglected orders, and as large general collections of insects have been obtained from what were, at one time, inaccessible parts of Australia, a writer can now obtain satisfactory data as to the classification and number of Australian insects hitherto wanting. With these views the present text book has been prepared. TABLE OF CONTENTS. PREFACE iii. CONTENTS vii. LIST OF PLATES xi. INTRODUCTION xiii.
