otlier six legs end in three claws. It is proved that this animal 

 belongs to the same genus as the Acarus deutlculatus Schrank = 

 Nicoletia corunta Can. et Fanz. — The name Lab'ulostonima is 

 wrongly spelled; orthographically we must write Labldostoma. — 

 Here we have a generic name , which is not preoccupied and 

 therefore must be adopted. 



In 1882 G. and R, Canestrini proposed the generic name 

 Nicoletlella to substitute Nicoletia, which was preoccupied. This 

 was quite superfluous. 



Thus we have the genus i/(aöiß?o#^owä! Kramer, 1879; synonyms: 

 Panoplia Von Heyden, 1826 (non Pa^/o/j/m Hübner, 1816); i>'ico- 

 letia Can. el Fanz., 1877 (non Nicoletia Gervais, 18..); Nico- 

 letiella G. et R. Can., 1882. 



The two species, belonging to this genus are : 



1. Labidostoma denticulatum (Schrank). Synonyms : Acarus 

 denticulatus Schrank, 1781; Panoplia denticulata (Von Heyden), 

 1826; Nicoletia cornuta Can, et Fanz., 1877, 



2. Labidostoma luteum Kram. 1879. 



The family therefore must be called Labidostomidae.
