The first Acarus, belonging to the subfamily of Antenno- 

 phorinse, was described in 1877 under the name of Antenno- 

 phorus Uhlmanni by G. Haller^ who found it on ants in Ger- 

 many. In 1886 Berlese^ added to the genus A. scolopendra- 

 rum, found in Italy on Scolopeiidra sp. and in 1888 he added 

 two new species, A. caputcarabi and viduus found by A. Bal- 

 ZAN in South-America, the former at Matto-grosso in Brazil, 

 the latter at Rio- Apa in Paraguay. 

 i In 1892 he raised the genus to a family, the Antennopho- 



f ridce in which he inciuded the genus Megistanus, which was 

 created by Thorell* in 1882. 



During the last years several new species'^ have been des- 

 ^ cribed, so that Berlese 1904 in his most valuable paper Acari

^ I do not take into consideration in the present paper the genus 

 Megistanus, which is certainly not so closely related to the other genera as 

 they are to each other.
