Arcfop/iila, according to Schiner, its founder, should have con- 

 siderably thickened liind femora and curved hind tibiie, but Verrall 

 in describing A. mussitans, F., says, "hind femora rather thick, 

 hind tibiic sliglitly curved" ; as, therefore, the characters are not 

 so pronounced in the latter case, the present species is referred to 

 this genus, thougli the liind femora and tibia? are but little thicker 

 or more curved respectively than the others. The genus is, how- 

 ever, otherwise sufficiently characterised.
