denticles. Legs stout ; fourth pair very much longer than the three anterior pairs. 

 Numerous hairs and spines are present on the legs and only the more conspicuous of 

 them are mentioned in this description. One of the two hairs at the distal end 

 of the dorsal surface of the femur is of great length. Anterior surface of coxa 

 of second leg finely serrate and armed with a small but distinct tooth ; femur of 

 this leg with a fairly loDg hair at the distal end above, and a strong but not very Ions: 

 spine on its ventral surface; a similar but finer spine occurs in the same position 

 on the femur of the third leg. Trochanter and femur of fourth leg each with a 

 long and conspicuous spiniform seta. There are a number of spines on the tarsi of the 

 second and third legs, but only fine hairs on that of the fourth. Colour dark brown.

6 . Body practically subcircular in shape, its length bein.g slightly less than the 

 width, but the shoulders are somewhat squared. Cervical grooves of scutum short and 

 inconspicuous ; marginal grooves are not present ; festoons not visible on dorsal 

 surface. Some distance in front of the posterior margin there is a dark narrow 

 central line, which is smooth (unpunctured) and slightly raised, and on either side 

 of this linear marking at some distance from it there is a short shallow oblique groove 

 with a smooth posterior border. Surface of scutum densely punctured throughout, 

 the punctures deep and well defined. Eyes obsolete. Stigmal plate large and very 

 wide. Base of capitiihim with distinct cornua ; each half of the hyposfome has 

 four longitudinal files of denticles, but the innermost file is shorter and the denticles 

 of which it is composed are much weaker than is the case in the other files. 

 Legs : first coxa armed with two rather short spurs ; coxse 2-4 also with two spurs, 

 the inner ones being small and inconspicuous, but the outer ones well developed. 

 Trochanters of legs 2-4 each armed with a distinct spur. Tarsus of fourth leg without 

 a distinct hump, but with the terminal part rather gradually narrowed. Colour : 

 scutum dark brown, but there are very faint traces of light green markings on it, 

 two patches near the posterior margin being fairly distinct (probably these markings 

 are distinct and much more extensive in well-preserved specimens). 



Ljength of body (not including capitulum) 2'4 mm.
