NOMENCLATURE. 27 



of Cicindela is now applied to the Tiger Beetle, and that of 

 Lampyris to the glow-worm. 



As to the arrangement of this large and important group of 

 insects, there have been, and are still, many conflicting opinions. 

 Some entomologists divide them into a number of distinct 

 families, while others gather them all into one family under 

 the common name of Cicindelidse, but subdivide that rather 

 unwieldy family into a number of tribes. I certainly think 

 that the latter plan is the most in accordance with zoological 

 fact, and I have therefore followed it in this work.
