of ticklers, bee-parasites, fleas, thysanura, 

 anoplura; and concluding observations.

 the case with the Papilionites, Cimicites, and 

 Cicadites : other orders limited to a single genus, 

 as Panurgites, may, perhaps, eventually, when 

 better known, merge in some neighbouring order. 



813. Besides the orders already described under 

 their respective classes, there are others which do

 unknown. Imago with antennae eight-jointed ; 

 mandibles long, corneous, and possessed of hori-
