222 VARROA JACOBSONII. 



ventrally hairy; only legs IV have ventrally only one distal 

 strong thorn on each joint (fig. 2). The ambulacra have 

 no claws and consist only iu an enormous almost bell-shaped 

 adhesive disc, being thus well fit to fasten the creature on 

 the smooth surface of a flying and always moving bee. 

 Habitat parasitical on Apis indica Fabr. 

 Patria: Java (Semarang). 



Collected by Mr. Edward Jacobson and presented by 

 him to the Zoological Museum at Leyden. 



Remark. The Museum above mentioned received these 

 mites (four females) and the bees, from Mr. Edward Jacobson 

 at Semarang. The larvae, protonymphae, deuteronymphae and 

 males are not yet known. They may be found in bee's 

 nests, in the dust and dirt at the bottom of the nests and 

 in the honey-combs, probably on the larves of the bee. At 

 all events the discovery of these female mites is a fortunate 

 one and a brilliant contribution to parasitism. Mr. C. 

 Ritsema Cz,, Conservator to the Museum, had the kindness 

 to send them to me for examination. 



Arnhem, April 1904.
