approximately equal length; segment 2 arising from pedicle, with 

 straight outer margin, convex inner margin, and subparallel ante- 

 rior and posterior margins; segment 3 with lateral margins slightly 

 converging to bluntly rounded anterior margin, posterior margin 

 straight though forming a slight, more or less downcurved projec- 

 tion at junct\ire with inner margin; segment 3 ventrally with 

 short, broad spur reaching basal margin; segment 1 narrow, 

 pediclelike, not observed to bear a ventral knob as in male; 

 palpi with hairs as illustrated. Hypostoroe larger but otherwise 

 similar to that of male. 



Scutum three-fourths as wide as long; outline slightly convex 

 anterior of eyes, slightly converging from eyes to juncture of 

 cervical grooves, abruptly converging posteriorly; anterior emar- 

 gination deep. Cervical grooves reaching lateral margins as in 

 male and delimiting an anterolateral area that is hirsute and 

 somewhat punctate as in male. Surface otherwise smooth except for 

 a transverse row of hairs bordering anterior margin between cervical 

 grooves and a few scattered hairs arising from punctations in cen- 

 tral field. Etyes on lateral margins at scutal midlength, slightly 

 convex. 



Spiracular plate of similar construction to that of male 

 but differing slightly in outline. Genital apron a wide oval 

 at level of coxae II . Genital grooves subparallel to level of 

 spiracular plates, thence divergent to level of posterior margin 

 of anvis. 



Integument with numerous fairly regular rows of short hairs 

 on both dorsal and ventral svirfaces; heiirs more dense on posterior 

 margin between spiracular plates. 



Legs similar to those of male except that the free segments 

 are narrower and tarsi more elongate; tarsus IV lacking ventral 

 siibapical spur; anterior projection of coxa I variable, as dis- 

 tinctly produced as that of male or more truncate. 



NYMPH (Figures 352 to 358): Gapitulum . Basis capituli 

 three times as wide as long, with straight basal margxn, roiinded 

 junctures, and divergent lateral margins. Palpi four times as 

 long as wide; segment 1 forming a slight pedicle; segments 2 

 and 3 of approximately equal length and subrect angular; apex
