This species may prove to be the same as that described below as WN. spinipes. In 
many structural points the two are evidently closely allied; but since Humbert and 
de Saussure say nothing about the spine-armature of the lower surface of the femur 
and patella of the anal legs, one is compelled to refer to the figure for information on 
this point: so far as can be judged, the four strong spines which project from the 
lower surface of the femur in J. spinipes, as well as in the other species of this genus 
(three in WV. pusilla), are represented by about two much smaller spines; and one cer- 
tainly has no right to assume without further evidence that the authors overlooked such
