ing that the trichomes are absent on the ventral 

 plates (of the adult). They appear even on the 

 genital valve of the female. Nymphs — not known 

 to Michael or Berlese — do not present any notable 

 feature. The characteristic trichomes are present 

 but less numerous than in the adult.

Type : obscura, Koch (according to Berlese !)

 generic name here is technically indefensible.

Length 900-1, 2oOyu.. Outline a long oval; dorsum 

 strongly arched ; colour dark reddish brown ; 

 surface slightly scabrid. The median scutum 

 merges into the marginal in front, where there is a 

 very slight pseudo-cephalic prolongation of the 

 dorsum. The whole dorsal surface is pretty densely 

 and rather coarsely punctured ; but as usual there 

 is a median strip with modified cuticle — smoother 

 and more finely punctured. This strip is broad 

 behind, tapering gradually forward, bounded on 

 either side by the two innermost rows of setae, and 

 runs to the extreme edge of the scutum behind, 

 thus including the area which in obscura is cut off" 

 by a transverse furrow. There are three rows of 

 setpe on each side of the median scutum, and one
