Appendix Entomology of the Rose. 



357 



of insects, which will we think be of assistance for the better handling of our subject. Many 

 authorities, from Linnseus downwards, have occupied themselves on this subject, and in 

 consequence many systems have been put forward. The one, however, which recommends 

 itself to us as being the simplest and easiest to comprehend takes the pupa or chrysalis state 

 as the basis of the arrangement, and divides insects into eight orders, viz.: 



LEPIDOPTEBA Consisting of moths and butterflies. 



DIPTERA Represented by gnats and the common house fly. 



HYMENOPTERA Examples : bees, saw flies. 



COL.EOPTERA Consisting of beetles. 



STEGOPTERA Examples : caddis flies. 



NEUROPTERA Examples : dragon flies. 



ORTHOPTERA Such as grasshoppers and crickets. 



HEMIPTERA Of which a better example than the aphis can hardly be cited to the Bosarian. 



Having thus given an outline of the various orders into which insects are divided, we will lay 

 before the reader a synopsis of such insects as may be deemed really injurious to the Rose. 

 It is somewhat difficult to estimate what proportion of the whole of the depredators of the 

 Rose this list includes ; although the observations from which it has been compiled have 

 extended over a considerable period their area has been necessarily limited, and therefore 

 the non-appearance of many injurious species, by reason of climate, locality, and soil, is 

 possible. Much remains yet to be done. Observations from various parts of the country, duly 

 chronicled, would afford much useful information, and all that this list can pretend to is the 

 enumeration of such species as are universally noxious, or, if local, especially destructive 

 where they occur.
