that based on the varying length of the palp and of its 

 segments. It should be noted, however, that large and small 

 males of the same species present some appreciable difference 

 in this respect ; in small males the pal[)al segments tend to 

 become rather more elongated than in large ones of the same 

 species. I give tentatively the following key : 



Preliminary Key to the Species of the Genus 

 STASIMOPUS, 



BASED ON STRUCTURAL CHARACTERS OF THE ADULT MALES. 



I. 1. Pressed forwards the palp reaches a point about ^ or 



•■* of the distance along tibia I, the patella distinctly 



shoi-ter than patella I : metatarsus I not scopulate, 



with strong spines on either side but not along the 



median area inferiorly : tarsvis I with 2 or 3 spines 



on the anterioi- side and 7-8 on the posterior side, 



lY with a strip of spines along the anterior side 



except in the basal ^ or |^ : tibia III with a few 



spiniTles at the apex above : the three keels of the 



carapace are depressed, the lateral ones flattened out 



and transversely ridged, the ridges becoming lost 



in the reticulation of the sides of the cephalic area. 



(King Williamstown.) S. insculptus Poc. 



a . Similar to the typical insculptus but differing 



as follows : Metatarsus I without spines or 



spinules below or at the sides, or only with 



one or several spinules at the sides. (Peddie.) 



S. insculptus var. peddiensis var. nov. 

 h. Similar to insculptus but differing as follows : 

 Metatarsus I with strong spines below both 

 over the median area and at the sides and 

 bearing a few scopular hairs near the apex : 

 tibia III with a dense patch of short spinules 

 at the apex above : tarsus I with 10-12 spines 

 on both anterior and posterior sides, IV with 

 many spines on the anterior side and about 

 13 on the posterior side. (Qumbu.)

 2. Pressed forwards the palp not quite reaching the apex 

 of tibia I, the patella short, half as long as tibia I :
