 and abdominal lobes semicircular or crescent shaped of equal 

 width though, if we exclude the hyaline membrane (which

 sufflexes a little ventralward laterally, apparently to clasp 

 the female during copulation. Hairs. Outside of the proxi- 

 mal ends of epimera I a pair of very small hair. Before the 

 proximal epimerites IV a pair of ditto. Inside of the proximal 

 ends of epimera IV a pair of ditto. On the posterior margin 

 of the genital shield a pair of ditto. In the middle of the 

 lateral shields the accompanying smaller thin lateral hair ; 

 whereas the long one has become dorsal. 



Mandibles normal. 



Maxillae. The subcapital median tubercle is not very 

 distinct. 



Legs as long as or slightly shorter than the width of 

 the abdomen ; comparatively thick. 



Habitat. Totanus f usais. 



Patria. Probably the geographical distribution of the 

 mite is the same as that of the bird.
