 capitulum ; when gorged may attain 11x7 mm. Body light grey when 

 alive, thickly clothed with white hairs. Scutum : (1*6 x 1*1 mm.) dull 

 yellow-brown, a few short hairs or hairless, much longer than broad, 

 broadest near its anterior end ; cervical grooves well marked, long, 

 reaching the posterior border ; no lateral grooves ; numerous moderate, 

 deep punctations ; emargination almost absent ; scapulae often some- 

 what rugose. Venter: very hairy in young specimens: the hairs are 

 absent in the region corresponding to the anal plate of the male, and 

 are caducent in the anterior portion in older specimens. Vulva facing 

 the second intercoxal space ; genital grooves sub-parallel for half their 

 length, then slightly divergent ; anal grooves slightly divergent; spiracle 

 (Fig. 259) nearly circular. Capitulum (03 mm. I.), base much broader 

 than long, slightly broader in front ; porose areas oval or semilunar, the 

 interval very narrow ; palps far apart at their base, article 1 conspicuous 

 dorsally, article 3 broader than article 2, giving the palps a clavate 

 appearance (articulations 2, 3, indistinct). Digit (see Fig. 258). 

 Hypostome strong, well covered with 2 1 2 strong equal teeth, about 

 8 per file. Legs : long and more slender than in the J, leg 4 not
