INDEX ENTOMOLOGICUS; 



OR 



A COMPLETE ILLUSTRATED 

 CATALOGUE 



OF THE 



LEPIDOPTEROUS INSECTS OF GREAT BRITAIN. 

 By W. WOOD, F.B..S. & F.L.S., &c. 



The object of this Work is to incorporate, in one or two volumes,

 inhabiting Great Britain ; — reduced, where necessary, to a small size, 

 but with a degree of accuracy that will enable the Entomologist to fix 

 at once upon any particular Species he may wish to define. 



The utility of such an undertaking, if properly conducted, will be 

 readily acknowledged ; as we have not any Work that figures even a 

 tithe of the Species which are known at present to inhabit this country. 

 Any book, therefore, must become important to the Entomologist that 

 will comprise an accurate Figure of every Species of Insect, included in 

 the Order to which it belongs. 



It may be objected, that to combine so much in so small a space, it 

 will be necessary to reduce the Figures till we lose the essential charac- 

 ter. This, however, will by no means be the case. The larger Butter- 

 flies and Moths will not be reduced to less than an inch : some hun-

 magnifying. 



With reference to the Plates, it may not be improper to remark, that 

 they will be executed by the same Artist (Mr. W. Wood, Jun.), whose 

 accurate Figures are already before the Public, in the Illustration of the
