Remark s. 



1. Acaridlae. Latreille created a group of mites under this name 

 in 1806 (Consid. génér. and Gen. Crust. Ins), containing Trovi- 

 hidium , Erytliraens ^ Gamasus , Or ibata Rnd Acar us (^— Tyroglfplms), 

 Though Leach in 1814 already removed the first three genera 

 from the two last ones, it is clear that Latreille gave this name 

 to this group of mites with the genus Acarus (— Tyroglyphus) 

 as type. Leach , as I already said , removed the genera TroinUdium, 

 Ei'ylhraeus and Gamasus from Orihata and Acarus. Thus the group 

 of Acaridiae Latr. 1806 contained only the genera Orihata and 

 Acarus, but Leach now gave the name of ^mrir/t'.y to the restiicted 

 group. Subsequently Oribata was removed again fiom Acarus, 

 Sarcoptes was placed next to Acarus in the same group , Acarus 

 was s[)lit into several other genera and new genera were created 

 and placed into the same group ; even the group was split into 

 several smaller groups, but tliis all is the I'esult of the increase 

 of our knowledge, but the group itself is still the same. The 

 name Acaridiae is also used by Nitzsch in 1818 (Ersch. u. Grub. 

 Allg. Encycl.) and Acarides also by von Heyden in 1826 (Isis)
