slightly reciirx'ed and tht- ixjsterior stnuigly ])nicur\e(l; sidu e\-es linked 

 together. I.egs strung, moderately long, hesijined. Kelatixe lengths, 4, 1, 2, 3. 

 Palpi rather k)ng. bespined. Falces rather long, arched, parallel ; su|)erior 

 margin armed with three teeth, and the inferior with two. JNlaxillae li-'ng. 

 dilated, similar to f^rassodes. Labium longer than l)r()ad, somewhat parallel- 

 sided, apex obtuse, ."sternum cordate, jjosterior extremity acuminate, and termin- 

 ating between fourth pair of coxae, .\bfiomen o\ate. Spimierets compactly 

 grouped, cylindrical, long, truncated; inferior mammillae shorter and stouter than 

 sui)erior. 



This genus comes closest to Lc^todrassiis, e\en more so than Drassus dchilis. 

 In I.cf^todrassus the front median eyes are much the largest, whilst in Adclpho- 

 drassiis they are of ecpial size. In both genera. howe\er. the side eves are con- 

 tiguou-^. The stermmi and leg formulas conform to those of /'. drbilis.
