2. Tyroglyplnna. — Donnadieu was the first, who separated 

 Tyrogli/phus and its nearest allies under the name «Tyrogly- 

 phiens» from the other Acaridiae (Ann. Sc. Nat. (5), X, 

 p. 69, 1868.) Synonyms of this name are: 



Betriticolae , Mégnin, 1872, in Journ. Anat. Phys. 8, p. 337.

hypopiales).

3. Acarus L, Linné in his Systema Naturae, Ed. 1, Leyden , 

 1735, created this genus for the cheese-mite and allies. Amongst 

 the four species of Acarus he called the cheese-mite Pedicubcs 

 scaUei for he then believed that the cheese-mite was the cause 

 of the itch. Afterwards he called it Acarus siro (siro = itch). 

 The meal-mite he then called Acarus siro var. farinae , and 

 the very itch-mite finally Acarus siro var. scabiei. — Moreover 

 he took the expression Acarus from Aristoteles, who must have 

 meant by his «k«^* the cheese-mite, which he found ^v y'iQÌM — 

 in wax — . A conjectiire has therefore been made that t" 3<'74»/'j' 

 should been written èr rv^ûo. What it may be, I think we have 

 reason enough to consider the cheese-mite Acarus siro as the type 

 of the genus Acarus L. 1735.
