CHAPTER II. 



AN INTRODUCTION TO THE STUDY OF THE ANATOMY AND 

 MORPHOLOGY OF INSECTS. 



The body in all insects may be regarded as a simple thick- 

 walled tube, the cavity of which forms the alimentary canal. 

 There is no distinct continuous body-cavity, in which the 

 viscera lie, corresponding to the pleuro-peritoneum of a verte- 

 brate, or the continuous ccelom of a hollow-bodied worm 

 (nematoid) ; but all the organs are connected together by a 

 delicate sustentacular tissue^ formed of branching cells, in the 



Bibliography. — The general subject of insect anatomy and morphology.

Not an anatomical work in any sense, but often quoted ; a treatise 

 on systematic entomology. 



7. Fabricius, J. C, ' Philosophia Entomologica.' Hamburgi et Kilonii, 



1778. 



A curious little book, which is useful in regard to nomenclature of 

 parts, but of no use as a treatise on structure. His ' Systema Ento- 

 mologia;,' Flensburgi et Lipsia;, 1775, is a work on systematic ento- 

 mology.
