measures and measurements introduced by me are not applied 

 by future students in determining or describing the species, 

 especially the females or immature forms, the result will be 

 confusion. As a warning I may tell, that among the whole 

 material obtained by me from various sources only three 

 species had been determined (by three different Zoologists) — 

 typical specimens of €Ourse not taken into account — but all 

 three had been very wrongly named! 



Finaily a few remarks on the terminology. In the general 

 account of the tribe our interpretation of the joints of the 

 appendages and the corresponding names can be found. In 

 the description of the palps I ha ve abbreviated the names 

 of the joints, using trochanter, fem ur, etc. for the trochanterial 

 part, the femoral part, etc. Furthermore I use the denomina- 

 tion »foot» for the sum of the two-jointed metatarsus and the 

 six-jointed tarsus. Of the abdominal flagellum in the male 

 the short, slender basal portion is named »the stalk», while the 

 remaining large portion is described as »the main piece».
