Named tor the American arachnologist, the late Prof. X. M. llentz.

Fuiir <pi ( iinciis. oin- of them in duplicate and all of them tolerably 

 preserved, represent both sexes of this species. Cephalothorax of female 

 i that of the male too \auiii for determination of form) rounded subquadrate, 

 bi.iailest ami subangulated behind the middle, the rapidly narrowing front 

 almost >traight anteriorly, and scarcely more than one-fourth the width of 

 the posterior portion ; cephalic separated from the thoracic portion of the 

 corselet l'\ a rectangular incision and by the slightly concave curve of the 

 Miles of the anterior half; the cephalic is also distinctly darker than the 

 thoracic region. Nothing can be said of the eyes. The last palpal joint of 

 the male i> lar^e, rounded quadrate, about twice as Inn^-as broad : the palpi 

 of the female are a> >toiit as the base of the front tarsi, hairy, tapering oidy 

 mi tin- apical half uf the terminal joint, rather bluntly pointed, extending 

 nearly as far beyond the front as the whole length of the cephalothorax. 

 Abdomen as dark as the cephalic portion of the corselet, in the female 

 plump, rounded, slightly ovate, considerably larger than the cephalothorax, 

 tin- apex almo>t an-nlated: in the male rounded subfusiform, much longer 

 than the cephalothorax. but not greatly broader. Legs very hairy but 

 without conspicuous >pines, tin- femora very stout, and at the tip rapidly 

 tapering, the IVM \ tin- h-M> diminishing in size less noticeably than in the 

 preceding species.
