three usual anal setae and three larger most anterior accessory setae. 

 Ventral body setae not so numerous as in adults. Peritreme weakly 

 chitinized, differing from adults in that tubular portion extends to 

 level of midpoint of coxae II ; lateral flaps present. Epistome as in 

 adults. Chelicerae as in female but relatively shorter. Maxillae not 

 clear. Setation of palpi as in adults. Legs as in adult female but 

 may be relatively shorter. 



Remarks. — Distinctive features of H. harperi^ which make it pos- 

 sible to distinguish female, male, and nymph from those of other 

 species are: Female: All setae smooth; relatively narrow dorsal 

 shield ; small number of accessory setae on sternal shield, four to seven 

 in specimens examined ; stout usual sternal setae with embossed bases ; 

 narrow genitoventral shield with relatively small number of setae, 

 11 to 18 in available specimens; anal shield relatively narrow; over 

 twice as long as it is wide ; with seven accessory setae which are larger 

 than usual anal setae ; anus almost entirely in posterior half of shield ; 

 both chelae toothless; relatively short tarsi which narrow abruptly 

 distally; short, stout setae on distal ends of tarsi. Male: Setation 

 as in female ; narrow ventral shield, which does not cover entire ven- 

 tral surface or curve anteriorly lateral to coxae IV; second pair of 

 usual sternal setae on lateral margins of shield; accessory sternal 

 setae absent; long, narrow anal region; femur, genu, tibia, and tarsus 

 of leg II each with a conspicuously strong ventral seta ; that of tarsus 

 II about midway between anterior and posterior ends of tarsus. 

 Nymph : Setation as in adults ; ventral shield more gradually tapered 

 posteriorly than in other species; anal shield with six setae; acces- 

 sory setae larger than usual setae; mouth parts as in female; short, 

 abruptly tapering tarsi as in adults. 



Size. — Seven measurable females varied in length from l,075;Lt to 

 1,300/a; mean length was 1,129/^; it was impossible to obtain accurate 

 measurements of width. Eighteen measurable males varied in length 

 from 925ju, to 1,025/x; width of the same series varied from 55/a to 

 600)a; mean length was 968/x; mean width 555ju,. Length of measur- 

 able nymphs was 975/x and 800/x; width of the latter specimen was 

 475/..
