I. TRÄGÅBDH, DISCOMEGISTUS NOV. GEN. 



Discomegistus pectiuatiis nov. spec. 

 With the characters of the genus. 

 Male: Length 720 jx. Width 900 [x. 



Colour straw-yellow. Texturs finely scaly. The shape of 

 the body is very extraordinary, on account of its length being 

 only ^3 of its width. As far as I know, the present form is 

 the comparatively broadest one yet known amongst the acari. 

 The ventral side is flat, the dorsal one very slightly are hed. 



The body is broad oval, posteriorly well rounded, almost 

 semicircular; anteriorly the median portion of the edge is

set off by a sinuosity from the antero-lateral portions or 

 »shoulders», which project forward to nearly the same level 

 as the median portion. 



The dorsal shield (Fig. 1) is protected by two shields, one 

 central and one marginal; the central one covers almost the 

 whole surface and leaves unprotected only a very narrow strip 

 of soft cuticle, surrounded by a comparatively broad marginal 

 shield, which extends forwards to the shoulders, where it narrows 

 abruptly to a narrow börder. As a matter of fact, but for 

 the marginal shield the outline of the body would be an 

 alniost perfectly equilateral oval.
