OF SOME RHODESIAN TENEBRlONIDiE. 1)3 



legs strongly fosso rial ; anterior tarsi without marginal pro- 

 jections other than basal spines. Spines on inner margin ot* 

 anterior legs : — 



Tarsal claw 1, at base, moderately prominent (note also one 



projection short and rounded, on outer side of 

 claw at base). 



Tibia 1 to 3, usually 2, moderately slender and sharp. 



Femur 2 to 3, short and blunt. 



Trochanter 2, short and blunt. 



Dorsal surface of anal segment concave in profile ; chitinoiis 

 projections on posterior and latero-posterior margin mainly 

 in form of stout spines and moderately numerous (14-20). 

 Pseudopodia prominent and not armed with spines. 



Type No. 2. (Plate lY. fig. 2 ; Plate V. fig. 2 ; Plate VI. 

 fig. 2). 



Recorded up to 24 mm. in length, but specimen much 

 distended; greatest length from living specimens 20 mm. 

 Specimens nearing full growth are much darker than Type 

 No. 1, especially on the dorsal surface, which is of a rich 

 brown colour, the under parts being yellowisli brown. Owing 

 to the darkest coloration on each segment being sometimes 

 confined to the middle region specimens may present a 

 banded appearance. This type differs from No. 1 in the less 

 marked lossorial development of the anterior ])air of legs 

 (see Plate VI. fig. 2), and in the paucity of the spines on the 

 margin of the anal segment : in the specimens in our 

 collection these number only three a side (see Plate IV. fig. 2). 

 It is noteworihy that in these and other characteristics, Type 

 No. 2 approaches nearer to the \xv\ix of G. simplex than to 

 the commoner type of G. a? quale larva. The spines on 

 the inner maroin of the anterior leos are as follows : — 



Tarsal claw 1, prominent (also one equally prominent on 



outer margin at base). 



Tibia 3 to 4, moderately slender and sharp. 



Femur 2, moderately prominent. 



Trochanter 1; moderately prominent.
